Acid induction furnace refractory concrete lining ram silica sand refractory ramming mass
It is a mixture of quartz sand as the main raw material and a small amount of sintering agent.ramming mass are divided into acid ramming materials. It is used as the lining of coreless medium frequency furnace and cored induction furnace. It is very suitable for melting gray cast iron, cast iron alloy, melting carbon steel, alloy steel, high manganese steel, stainless steel, melting aluminum and its alloy, melting copper, brass, white copper and bronze and other copper alloys.
1. Silicon carbide ramming material has high strength and good corrosion resistance to liquid slag
2. Due to the addition of a resist with high hardness and good corrosion resistance in the ramming material, it can reduce the erosion of alkaline substances on the furnace lining
3. It can make the thinner liquid slag hang a layer of slag on the furnace lining to form a slag film and protect the furnace lining
4. Silicon carbide ramming material has small thermal expansion coefficient, good thermal shock resistance and good thermal conductivity
