Application:
Carbon bricks are widely used in variety heating environment. There are blast furnace carbon bricks, electric furnace carbon bricks, calcium carbide furnace carbon bricks, aluminum electrolytic cell cathode carbon blocks(semi graphite cathode carbon blocks) ,etc.
Advantages:
High refractoriness and high refractoriness under load.
Good thermal shock resistance.
Good resistance to molten slag or iron liquid impregnation.
Excellent resistance to various kinds of salts and organic materials corrosion.
Strong slag erosion resistance, good high hot volume stability.
High mechanical strength, good abrasion resistance.
Excellent thermal conductivity.
Our main exporting brand of refractory bricks are:
Direct bonded magnesia-chrome bricks
ííííthe product is manufactured by taking high purity magnesia and high quality chrome as raw materials through the process of high pressure moulding and high temperature burning.It has a good thermal shock resistance and volume stability and is applied in the cement and glass industries.
