What are the materials for induction furnace lining?
The selection of induction furnace lining materials mainly depends on factors such as furnace type, type of smelting metal and working temperature. Common induction furnace lining materials include acidic refractory materials, neutral refractory materials and alkaline refractory materials, as well as some special materials.
Acidic refractory materials
Quartz ramming mass: low cost, high refractoriness (about 1700°C or above), but poor thermal shock resistance, suitable for melting acidic slag (such as siliceous slag) environment, often used for melting cast iron, copper and its alloy induction furnace lining
Neutral refractory materials
Corundum dry ramming mass: suitable for melting different types of metals, with good chemical stability and high strength, high refractoriness, good thermal shock resistance, suitable for melting steel, stainless steel, copper and its alloy induction furnace Furnace linings
Magnesium-aluminum spinel ramming mass: has good corrosion resistance and thermal stability, suitable for induction furnace linings for melting special steel or high alloy steel
Basic refractory materials Magnesium ramming mass: suitable for melting alkaline slag (such as magnesium slag) environment, high refractoriness (about 2000°C or more), good alkaline corrosion resistance, suitable for induction furnace linings for melting carbon steel and alloy steel
Magnesium-chrome bricks: has good slag resistance and refractory performance, suitable for high temperature and slag resistance environment
