Carbon Brick is a kind of neutral refractory material that can resist high temperature erosion, which are manufactured with carbonaceous as the raw material and added suitable binding agent. Carbon Brick can be used in the blast furnace to built furnace bottom and hearth with its features of good thermal shock resistance and low thermal coefficient of expansion.

Description For Carbon Brick
Carbon brick includes raw materials of anthracite, coke and graphite, and binding agents of pitch, tar and carbolineum. Anthracite has few volatile component and dense structure, which is often used as aggregate and then added metallurgical coke with pitch as the binding agent when manufacturing carbon bricks for sale.
Carbon Bricks Manufacturing Process
Carbon Bricks Manufacturing Process is similar with other refractory fire bricks’. But it is necessary to prevent carbon’s oxidation in the high temperature. So all the firing for the raw materials and products must be produced in the reducing atmosphere. Calcine anthracite to eliminate volatile component, sulfur content and moisture before using. And improve the anthracite’s volume stability, mechanical strength and inoxidizability. Dry coke to avoid the crack in the firing process caused of much more moisture contained. Fuse pitch and dry it in the temperature between 120~160℃ till its moisture is lower than 0.2%.
Carbon Bricks Properties
Carbon Bricks have properties of good thermal shock resistance, low thermal coefficient of expansion, high temperature resistance, and resisting erosion from all kinds of acid, alkali, salt and organic solvent. Carbon Brick is easily oxidized in the oxidizing atmosphere.
Carbon Bricks Application
Carbon Bricks are widely used in the metallurgical industry. Of which carbon bricks are more used in the blast furnace. Many blast furnaces’ furnace bottom and hearth are built with carbon bricks.Carbon Bricks uses,Carbon Bricks supplier
Carbon Bricks also can be used for pickling bath, plating bath in the electroplating industry, for the dissolving tank in the paper manufacturing industry, for the reactive tank and storage tank in the chemical industry, and for the autoclave in the petrochemical industry.Leave your requirements about our refractory bricks.
