2,Conditions that must be met for carbon bricks for furnace bottom:

1) Hot metal can not be immersed into tissues through stomata.

2) Less melting due to molten iron

3) High heat conductivity and good cooling effect

4) Strong alkali resistance

5) Low permeability to prevent zinc and oxidizing gas intrusion

6) Low elasticity, high strength, heat shock resistance

3,Types of carbon bricks for hearth and bottom of blast furnace:

1) Standard carbon bricks

2) Ultrafine Porous Carbon Bricks (Graphite Bricks)

3) Microporous semi-graphite brick

4) Graphite Bricks

4,Characteristic of Carbon Brick For Blast Furnace Hearth: It is easy to be eroded by air, carbon dioxide and water vapor, as well as iron and alkali metals at high temperature,The damage mechanism of different parts of blast furnace lining is different. Carbon refractories of different materials must be selected according to the damage mechanism and cooling conditions.The product has good thermal shock stability, small coefficient of thermal expansion, high temperature resistance, corrosion resistance of various acids, alkalis, salts and organic solvents. Carbon brick is widely used in metallurgical industry, in which the consumption of carbon brick in blast furnace is the largest, such as the bottom and hearth of blast furnace. In addition, carbon brick is well used in pickling tank, electroplating tank, dissolving tank in paper industry and reaction tank in chemical industry.

5.Good feedback of product use effect,the products have been exported to Australia, Kenya, Mexico

6.We are a professional supplier, who can provide customers with free product technology, use and other issues.
