Special Insulating Bricks

It is made under the standard of JM international standard.The main
characteristics of this priduct are:low Fe2O3 content,even structure,
good heat shock stability,low thermal conductivity,excellent penetration
resistance in the reducing condition,It may be widely used as the lining
or heat insulation layer of various kiln such as blast furnace,hot blast
furnace,silicon steel heat-treating furnace,hot galvanizing furnace,
penetration resistance furnace,ethylene cracking furnace,hydrogen making
furnace,single-stage invert furnace,sulphur recovery device roller kiln,
shuttle kiln and so on...
