Acid lining material
I. General introduction
A-- *** Acid lining material is made of the highest purity silicon ore and powder, and specially added part of fused quartz, adding high temperature sintering agent and mineralizing agent and using a proprietary particle size ratio mixed. It is mainly used for the working lining of coreless induction furnace for melting, insulating cast iron and general carbon steel. The main features of the product are resistance to acute cooling and heat, anti-erosion, anti-erosion, oven and use of the furnace lining rise is small, cold furnace without cracks, especially suitable for large and medium-sized induction furnace intermittent operation.

4. Packaging and storage
Three layers of moisture-proof paper plus one layer of inner membrane, 25Kg/ bag. Store in a cool, dry environment for 12 months. Store in a dry place to prevent moisture absorption.
5. Furnace building and sintering process
The correct furnace building and sintering process is the key to the normal work of the lining, before the furnace building and oven sintering, please refer to Hubei Anaijie furnace lining Material Co., LTD.
