The 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.
