  • GREEN THINKING..... IN OUR MINE

    In our working mine, we reduce the "Visual impacts" avoiding work in areas that are displayed from the usual passage of people. As you can see in the photo, the front of work mine is holding on the side of the mountain refugee from the village and the road,  so you can not see the mine from both. A ...

With two stages : One promising, wit ...

  • THE CAN VALUE

    Do you know that a can has one of the most fast recycling processes? 90 days are estimated from when you consumed to get back on the supermarket. Aluminum is one of the most valuable waste household garbage. The average price in 2010 for recovered aluminum was 350 euros per ton, if we compared with ...

  • IT IS TIME TO JOIN FORCES

    It is time to join forces, cooperations,agreements and collaborations. In this way, INSERTEC, has signed three collaboration agreements with: 1.- ELKEM 2.- STELLAR CANADA. 3.- STELLAR MATERIALS USA ELKEM: Norwegian manufacturer of refractory materials "CERAMITE".One of the materials that arise of t ...

  • What is the silicon lining of an induction furnace for a refractorist?

    It is the refractory ceramic element that separates an energized coil with water flowing inside and the liquid iron at high temperature. ...

  • What should we monitor during the melting?

    - Do not raise the temperature beyond what is strictly necessary. - To control the melting process. - Keep the metal for the shortest possible time. - Maintain the shortest possible time the furnace in a sloping position or spillage with molten metal. - Perform the necessary strain and return the fu ...

  • What should we monitor at the start of melting?

    - To verify correct melting of the metallic load realized in the sintered one. - Indispensable to have maintained for 1 hour, 50ºC above the nominal temperature of strain. - Check thtaa the vent-walls is in good condition and there is no crack formation. If any apply a plastic mass in the zone as I ...

  • Does the induction influence the wear of the lining?

    Yes. The electromagnetic agitation provokes the movement of the metal inside the crucible. The speed thereof is resposible for the erosion on the wall of the lining. ...

  • Why do the walls at the bottom of the furnaces wear away more?

    When melting with the foot of bath the most frequent wear takes place in the bottom part of the furnace. This type of wear it is known as elephant leg. By adding a new load for melting and putting power, a part of this one warms the metal of the bottom doing that this raises its temperature favourin ...

  • Why do horizontal cracks appear in the lining?

    There is no single answer. There are several possible reasons that we can number as being responsible for the appearance of these cracks: -  Lining  compaction inappropriate. - Segregation of the lining. - Loss of thin through the coil. - Hanging of the lining from the pan. What can happen? Most l ...

  • Why do vertical cracks appear in the cooling?

    The formation of cracks is inherent in the nature of the raw material quartzite when the silicon lining are done. They are contractions and volume changes involving breakage of the lining. What can happen? The vertical cracks, normally they close. What to do? - Ideally working in 3 shifts and the fu ...

  • What is the natural mechanism of wear away of silicon lining?

    The carbon reduction of the silica is a natural reaction accentuated with temperature. SiO2 lining + 2 C metal > Si metal + 2 CO gas It is impossible to avoid this reaction and the silicon lining of the induction furnace will be getting worn out naturally. ...
