CUPOLA FURNACES

The dictionary defines a cupola as a domed roof, a gun turret or a vertical cylindrical Furnace to melt metal to further refine it in other furnaces, or to cast it into useful shapes. The editors of Encyclopedia Britannica claim that René-Antoine Ferchault de Réaumur built the first cupola furnace on record, in france, About 1720. Cupola melting is still recognized by some as the most economical melting process if the furnace is operated continuously. A lot of grey iron is still melted and cast by this method.  Improvements in the process over the last 200 years have included the construction of the larger furnaces and the application of the heated air at the tuyeres.  Many foundries however as we shall see have invested in other more modern furnace designs and INSERTEC are able to supply a complete range of  refractory lining products for all.cubilote croquis

Cupolas were traditionally lined with brick but in the last 50 years many of these units and other vertical shaft furnaces have switched to monolithic linings because the quality and availability of monolithic refractories have improved enormously and they are more cost effective when properly engineered and expertly installed.

At the top of the furnace the refractories must resist mechanical and thermal shock while in the lower part of the lining the most important properties are the ability to resist attack from molten metal and slag at elevated temperature. Intermittently operated furnaces are sometimes cleaned and given a protective wash on the hot face each day but continuously operated units must be constructed from premium products for long life and low cost.

INSERTEC, have a complete range of monolithics for the original linings of both ferrous and non ferrous furnaces of all sizes and you are invited to contact us for precise recommendations.

For economic and operational reasons many ferrous and nonferrous foundries have more recently invested in crucible and induction furnaces for melting and casting their products.

Crucible furnaces are one of the oldest and also one of the simplest types of melting unit used in a foundry where small batches of low melting point metal or alloys are required.  The charge is placed in a refractory crucible and heated mainly by conduction through the walls of the crucible using gas oil or electricity as the fuel. Most modern foundries however use electric induction furnaces for the efficient melting of both ferrous and non ferrous metals and alloys and these have largely now replaced crucible furnaces especially for elting of high melting point alloys such as cast iron and steel.  Induction furnaces are generally easier to control with regard to temperature and chemistry and better suited to the enviorement.

DEVELOPMENT IN CUARSIL RANGE

_JMA3024The metallurgy of iron ever needs faster melting processes. This fact make furnaces with high current density near the periphery of the lining ; for this reason the temperature in this area suffering the effects of overheating and logical sudden cooling of fusion process.

When lining has a good resistance to thermal shock will cause cracks, if dosent close, they are  the way of metal infiltration. These metal penetrations can compromise the final performance of all lining.

INSERTEC, have developed a complete range of CUARSIL IS6 PAN, with some improved performance thermomechanical that means, better resistance of the lining to the formation of cracks.

These properties have been got with a very studied particle size of the product and the mix of different qualities of quartzite for get  the optimum mineralogy  of the product.

This new development enables the lining of induction furnace to behave better against sudden changes in temperature, higher demands power from fusion of the furnace and, ultimately, getting to increase the service life of the refractory lining.

IDEX Our green furnace

IDEX® System

The IDEX® is designed to give maximum flexibility together with minimum fuel consumption and emissions. It is an indirectly fired rotary kiln for thermal delacquering / drying that removes volatile organic compounds (VOC), such as water coolants, paints, oils, … from the surface of crushed aluminium materials.1-sistema-idex-reciclado-aluminio-e6d04a0210

The system is completed with a postcombustion chamber for the incineration of the hazardous gases generated during the drying/decoating process.

Hot exhausted gases are recirculated to the rotary kiln to eliminate the VOC, without any additional energy supply and so reducing the overall thermal consumption to the minimum.

Final exhausted gases to the atmosphere are innert and comply with the most strict EU enviromental regulations.

ECO-Kiln® System

It is compact system where the postcombustion and drying chamber are in the same rotary kiln.

ALUMINIUM, Key in the construction of modern aircraft.

Link

A combination of lightness, ressitance and high electrical and thermal conductivity, is the property that became a key to Aluminium and its alloys, for the construction of aircraft,  automobiles, or engines, among many other applications. And it is that a given volume of aluminium weighs less than one-third of the same volumen of steel. Unique lighter metals are Lithium, Berylium and Magnesium.avion

On the other hand, only has a 63% of the electrical conductivity of the copper wire of the same thickness, but weighing less than half.  This means that a comparable one of cooper conductivity aluminium wire is thicker, but still lighter.  All of  this has its importance in case of  the transport of electricity of high voltage-700,00 volts or more-longer distance for what, precisely, are used for aluminium conductors.

TILTING ROTARY FURNACES

Due to the considerable savings produced during recycling and to the simplicity of the process, the aluminum started to be recycled a long time ago, and today is a widespread activity, technically solved and profitable, In fact, more than the 75% of the last 100 years produced aluminum is today in use because of the recycling.

Over the past 20 years , Insertec has developed a range of specific products for the aluminum recycling sector, in which we can remark tilting rotary furnaces.

Looking at this type of equipment, the refractory lining is one of the critical points , and where our refractory division provides differentiated and innovative engineering refractory solutions.

The success key in the performance of these solutions is given by the combination of 3 factors:

Design and selection of the more appropiate materials. (zones)

Best Lining design (anchoring way, insulation, thickness and geometry)

Correct installation.rotativos

REFRACTORY ENGINEERING purpose is to get together those 3 factor and INSERTEC, Ingeniería y Servicios Técnicos is able to reach the target giving solutions such as:

 

  • The use of REFRACTORY PRECAST SHAPES à remove the main disadvantages of the use of bricks and monolithic mases, providing all the advantages of each one of them:
    • Manufacturing according to a quality system: (moulds design and manufacturing, mixing, vibration, demoulding, drying and fyring) = Homogeneity in the technical characteristics in all the shape geometry.
    • Specifically designed (materials y geometry) = best behaviour taking into account the requirements of each zone of the installation.
    • The customer receives the shapes just ready for their installation and put in operation. They could be installed by mechanical team with some drawings and assemblying instructions.
    • Installation days and scheduled stops are considerably descreased.
    • There can be spares in the customer or in the manufacturer warehouse, so in case of non scheduled stop of the plant, replacement of the shape and repairing works are reduced at minimum.
    • The characteristics of the shapes are homogeneus and materials and designs the best in each application = increases in the life of the refractory components à less repairing costs (refractory and metallic elements that are protected by the refractory), and less operations inside the furnace.
    • Less operations inside the installation à less exposure of the workers to more occupational hazard (demolitión, equipments and tooling handling in reduced spaces, activities in reduced accesses zones,etc) = Improvement in SAFETY and Health conditions.
    • The possibility of accidents and incidents  decrease due to the minimizing of the number of repairing operations..
    • The increase in the life of the refractory components involve an enviromental and economical improvement due to the less waste creation and its latest management.

How we can optimize the performance of cupola furnace?

cubilote croquisMethods of improving the behavior of cupola:

  • Keep Furnace in optimum regime of operation.Relationship between inyection velocity coke charging & melting velocity (see Junblüth diagram)
  • Avoid excessive temperatures in the casting and reduce overheating.
  • Ensure uniform load: The distribution of metal and coke must be  uniform during charging.
  • Improve the control of charges weight , the inyection flow and metal temperature.
  • Minimize air leaks. Supply the correct amount of air is essential for the proper performace of the cupola. It is necessary to take extra care to prevent leaks and ensure efficent operation of the furnace. These losses are common in the hot wind cupola and take place in the exchanger of heat. As result, oxygen in the nozzles should be injected to compesate lost air.
  • Avoid vaults formation in the cupola. vaults stickings and jams of the load in charging area creates efficency loses during the melting and ocassionally, even in severe cases stop it completely.
  • Improve the Refractory linning. During the melting process,  the wear in the refractory linning modifies the dimensions of it; afecting directly to the performance. For this reason minimizing the attack to the linning , is a way of energy saving. The maintanaince of the linning must be taken carefully.

ALUMINIUM CAR

Some of the early designs used completely aluminium structure was built by a Norway company called BJERRING. They only manufactured 4 prototypes until the Lord  Raufoss take the control of the company and tried to transfer the advances developed in the space technology of aluminium frame design in cars and buses.

This project could not be held due to lack of resources and technolcoche alogy ( we are talking of 1930s). The first car manufactured using abodywork and structure entirely of aluminium was the PANHARD DYNA, a prototype made in France in 1954. This vehicle was powered by a two stroke engine, weiged only 629 kgr. and could carry 6 people.

METAFO 2015

METAFO fair is the largest fair of IRAN. This has been the twelfth edition. In 2014 doubled participation and designated space for the this Fair. FUNDIGEX has participated, on behalf of the ICEX in a grouped stand with Basque companies.INSERTEC, had its own stand.metafo2015stand

Since 15 years ago in Iran, The foundry has been growing, espacially the sector of steel and aluminium parts:

The production of casting can be decomposed into:

  • 70% Iron Casting
  • 8% steel parts.
  • 10% aluminium
  • 12% are castings of other non-ferrous materials.

70% of Iron castings goes to the automotive sector, which is growing in Iran and moves a significant volume of business.

MEDIEVAL IRON FURNACE in GALDAKAO (Spain)

In 2013, a reduction of iron furnace was located in Galdakao (Bizkaia-Spain). This building,is the largest in Europe, with 5.5 meters tall and 4 wide, this large furnace that was based on the manual work against others later which were helped from the force of the water was really great.horno galdakao 3

Before the revolution industrial, at the beginning of the 19th century, this metal (Iron) also was very  importan in Basque country life. The iron was good, had little phosphorus, for this reason they could manufacture more flexible tools. They obtaining the Iron through these funaces drilled on the slopes. They pouring the mineral into the furnace and with the heat  were obtained  iron in one side and slag on the other.

Researchers have given them the name of  “BASQUE FURNACE”. In fact, compared with other structures, the zone have walls curved – the European are straight- and channel which gives air is located on one side rather than in the center of the bottom.horno galdakao bis

We consider an  interesting news, because we can see that  this town has its history very linked to the iron, also seemed a curosity that one of the locations of INSERTEC was in this town.

The market situation is of general uncertainty. All are waiting for a recovery, but few companies dare to make new investments. There is not a clear tendency in  2015, even though we are forecast to close some projects before year’s end.

ITACOLUMITAS

Featured

Itacolumitas are special sandstones which reach this unexpected flexibility due to special interlocking of its grains, coming from its geological growth. Name comes from the Brazilian country of Itacolumia, Minas Gerais, where it was firstly identified.  This strange elastic behavior developed by nature, has been focused by scientists of different areas due to, for example, potential application of itacolumite inspired microstructures, to develop flexible concretes capable to resist, in terms of its own flexibility, vibration coming from earthquakes.
