What is the service life of the ramming material of the 20t induction furnace?
The ramming material is used for induction furnaces of 500kg to 10t, and the life of the furnace wall lining is usually about 250 to 450 heats, and the service life of the 20t induction furnace is up to 300 heats. In foreign countries, fused silica is more commonly used in cast iron induction furnaces. Compared with natural quartz ramming material, fused silica ramming material has the characteristics of small thermal expansion coefficient and excellent thermal shock resistance. At the same time, it overcomes the phenomenon that natural quartz has a thick sintered layer or even burned through during long-term use, and retains A sufficiently thick unsintered layer. Avoid crack penetration and ensure the safe and stable operation of the induction furnace. According to reports, the ramming material is used in induction furnaces of 500kg to 10t, and the life of the furnace wall lining is usually about 250 to 450 heats, and the service life of the 20t induction furnace is up to 300 heats.
