Self Roasting Carbon Brick

Self roasting carbon brick aggregate is high temperature calcined anthracite, so that, the self roasting carbon bricks composition is the powder material calcined anthracite and coke mixture, middle temperature coal pitch is serves as binding agent. At certain temperature, the raw materials are evenly kneaded and then molded into shapes by high frequency vibration. Self roasting carbon bricks not only have accurate dimension but also have specific physiochemical performances. 

 

Self baking carbon bricks have high refractoriness, good thermal conductivity.

Good high temperature strength, strong slag iron corrosion resistance

Simple production process, low price, good workability.

Self roasting blast furnace carbon bricks have accurate size, can be directly used to mason furnace lining without machining. 

Roasting can be carried out during roasting furnace and production, furnace lining almost has no joints.

Self baking carbon bricks can absorb temperature stress during furnace lining heating process, so thermal stress caused furnace lining damage can be reduced.

Due to the properties of self roasting carbon bricks and the qualitative change in blast furnace, blast furnace lining stability and endurance are finally improved. Therefore, self roasting carbon bricks lining are popularly used in middle size and small size blast furnaces and economic effect is very good. In large capacity blast furnaces, semi graphite self baking carbon bricks are adopted, which can not only decrease liquid iron melt index, but also increases thermal conductivity, enhances alkali corrosion resistance, improves oxidization resistance, increases washing abrasion resistance and reduces residual shrinkage.
