Carbon Bricks
The production process of carbon bricks is roughly similar to that of other refractory bricks, but the carbon must be prevented from oxidizing at high temperatures, so the roasting of raw materials and the firing of products must be carried out in a reducing atmosphere. Anthracite must be roasted before use to eliminate volatile matter, sulfur, and moisture, and to improve the volume stability, mechanical strength, and oxidation resistance of anthracite. The coke must be dried first to avoid molding difficulties due to excessive moisture content and cracking of the product during the firing pro

Carbon Bricks Details
The production process of carbon bricks is roughly similar to that of other refractory bricks, but the carbon must be prevented from oxidizing at high temperatures, so the roasting of raw materials and the firing of products must be carried out in a reducing atmosphere.
Anthracite must be roasted before use to eliminate volatile matter, sulfur, and moisture, and to improve the volume stability, mechanical strength, and oxidation resistance of anthracite. The coke must be dried first to avoid molding difficulties due to excessive moisture content and cracking of the product during the firing process. The asphalt must be melted and dehydrated first to make its moisture less than 0.2%, and the dehydration temperature should be 120 to 160°C.
The ingredients are roasted granular anthracite as aggregate, and its particle size depends on the size of the product: 8 to 12 mm for large bricks and 4 to 6 mm for small bricks. The amount of anthracite added is about 60%.

Application
1.Carbon bricks are widely used in the metallurgical industry. Among them, the largest amount of carbon bricks is used in blast furnaces. The bottoms and hearths of many blast furnaces are built with carbon bricks.
2.They are also used in aluminum electrolysers.
3.In addition, carbon bricks are also widely used in electrochemical industry, chemical industry, petrochemical industry, electroplating industry, ferroalloy industrial furnaces (or linings of equipment), acid and alkali tank linings and pipelines, and smelting non-ferrous metals (such as Aluminum, lead, tin, etc.) furnace lining.
