What refractory ramming material is used for the intermediate frequency furnace?

What refractory ramming material is used for how to make an intermediate frequency furnace? IF furnaces generally use quartz sand or neutral refractory ramming materials. The process is different. Generally, there are two types of blasting methods for intermediate frequency furnaces, one is dry and the other is wet. It is made of tuned quartz sand material with high temperature agent added in it. No matter which type, the old furnace must be disassembled and cleaned. The glass cloth is laid, the furnace bottom is discharged, and the furnace bottom depth is normal. Put the iron crucible mold in about two circles of the induction loop, fill the material, pay attention to the right position, dry beating and directly smash it firmly, wet beating is to fill the material with water, and then beat the iron crucible mold to make the material strong , And finally pull out the iron crucible mold at the right time.
