Precautions for choosing ramming material for melting cast iron in induction furnace?
It is worth noting that not all quartz sand with SiO2>98% can be used as the lining of the furnace wall of the induction furnace. The important thing is the size of the quartz crystal grains. The coarser the grains, the fewer lattice defects, the better. Mainly for casting refractory materials, it provides enterprises with internal fire materials. Among them, the acidic furnace wall lining material is quartz refractories for coreless induction furnaces, and the material is acidic. Adding part of fused silica on the basis of silicon ramming material can obviously improve the disadvantages of the expansion of the furnace wall lining. The rise of the furnace wall lining during the drying furnace is significantly reduced, and the greater the capacity of the crack-free furnace during the cooling furnace, the higher the requirements for crystal grains.
