I. General introduction
170R4G acid lining material is made of pre-phase change silica sand and powder, adding a certain proportion of electromelting quartz sand, high temperature sintering agent and mineralizing agent, and using a proprietary particle size ratio. Mainly used for melting, insulation cast iron, general carbon steel coreless induction furnace lining. The product is especially suitable for the intermittent operation of large and medium induction furnace, can effectively improve the shortcomings of large expansion of the furnace lining, the furnace lining rise is small in the process of oven and use, the rapid cooling and rapid heating performance is excellent, and the crack rarely appears in the cold furnace.
