Production Process of Pre-baked Carbon block for Electric Arc Furnace
The production process of carbon bricks is roughly similar to other refractory bricks, but it must prevent the oxidation of carbon at high temperatures, so the baking of raw materials and the firing of products must be carried out in a reducing atmosphere.
The Pre-baked Carbon block for Electric Arc Furnace ingredients are roasted granular anthracite as aggregate, the firing temperature is 1300~1450℃, the holding time is about 20 hours, the total firing time is about 240~420 hours, and the kiln is cooled to 40~60℃. Carbon bricks leave the kiln at high temperature, which is easy to catch fire.
Feature of the Pre-baked Carbon block for Electric Arc Furnace
Pre-baked Carbon block for Electric Arc Furnace has good thermal stability, small thermal expansion coefficient, high temperature resistance, resistance to various acids, alkalis, salts and organic solvents, but it is easily oxidized in an oxidizing atmosphere.
Use of the Pre-baked Carbon block for Electric Arc Furnace
Carbon bricks are widely used in the metallurgical industry. Among them, the blast furnace Pre-baked Carbon block for Electric Arc Furnace is the most used, and the bottom and hearth of many blast furnaces are made of Pre-baked Carbon block for Electric Arc Furnace. Carbon bricks are also used in aluminum electrolytic cells. In addition, it is also widely used in pickling tanks, electroplating tanks in the electroplating industry, dissolution tanks in the paper industry, reaction tanks and storage tanks in the chemical industry, and autoclaves in the petrochemical industry.
Production capacity: Our factory actively response to government environmental protection policy, we designed and built the fully automatic controlled high temperature gas tunnel kiln (1700℃), and got capacity of annual output 70,000 tons of high quality refractory products.
