The classification of lining materials is varied, and the lining materials in the medium frequency induction furnace can generally be divided into three categories:
1. Acid lining material: the main component of acid lining material is quartz sand, chemical formula SiO2, its content is generally more than 98.5 percent, because quartz sand has low cost, moderate heat resistance, good shock resistance advantages, suitable for low melting temperature such as cast iron, cast aluminum and so on. Acid lining material can be used in medium frequency induction furnace lining for non-ferrous metals and ferrous metals continuous and intermittent operation environment.
2. Basic lining material: Basic lining material is mainly made of high purity fused fused corundum, high purity fused magnesia and high purity spinel as the main raw materials, and composite additives as the sintering agent. Mainly used in melting high alloy steel, carbon steel, high manganese steel, high chromium steel, tool steel, stainless steel and other alloy steel, medium frequency induction furnace lining.
3. Neutral lining materials: mainly materials containing more than 80% aluminum as the main material, such as calcined bauxite, fused corundum and so on. Bauxite has the characteristics of low cost, high refractoriness, good chemical stability and good shock resistance. Mainly used in melting gray iron, ductile iron, carbon steel, high manganese steel and other materials. And it is not easy to react with basic and acidic slag, and it is not easy to crack in indirect opening. The neutral lining material produced by Lingshou Detai Mineral Products Co., Ltd. is added with special binders and effective ingredients of anti-erosion and anti-sticking slag, thus giving the whole material a unique thermal performance. Generally can be used dry vibration or ramming molding, without maintenance and long baking cycle, heating through ceramic reaction sintering, to obtain high hot surface strength, to resist the erosion and penetration of liquid aluminum, while the unsintered liner to maintain a granular state, the liner can prevent local stress concentration, prevent the extension and expansion of hot surface cracks. ** Added to improve the corrosion resistance of aluminum and aluminum alloy, anti-sticking slag special ingredients, tied good lining, with aluminum and aluminum alloy non-reaction, non-etching, non-sticking slag and other advantages.
