Used for casting, cast iron, cast steel, cast will have a requirement for carbon, carburant just as its name implies is to increase the carbon content in liquid iron, and, for example, commonly used in smelting furnace charge for pig iron, scrap steel, back to the furnace charge, iron carbon content is high, but relatively scrap purchase price is higher section, so adding scrap supply, reduce the quantity of pig iron, increase carbon agent, can reduce the casting cost play a role.
The use of carbonizing agent can not only make up for the loss of carbon in the process of steel smelting and ensure the carbon content of specific steel brands, but also be used for after-furnace adjustment.
As an important raw material for melting molten iron in induction furnace, the quality and usage of carbonizer directly affect the state of molten iron
The carbon content in the ladle can be adjusted by adding a specific brand of carbonizing agent to the ladle after slag removal and gas removal.The main materials used for carbonizing agent are graphite, graphite, electrode block, coke, silicon carbide and other materials.The commonly used electrode block and silicon carbide carbonizer have the advantages of high carbon content and strong oxidation resistance.The production cost of coke powder and graphite is lower than that of electrode block, but the ash and sulfur content are higher and the carbon content is lower.
