graphite carbon block
The production process, method and purpose of graphite carbon block
The graphite carbon block and airtight paste produced by CGM Carbon are used in closed, semi-closed, and open submerged arc furnaces. They have achieved good results and are highly praised by many users.
The graphite carbon block production process is roughly as follows: raw materials (petroleum coke, coal, etc.) crushing-grinding-sieving-ingredients-kneading (add melted mid-temperature asphalt to the dry material, and maintain a certain temperature by steam heating. A mechanical stirring process under temperature)-molding-the impact on the environment during the production of finished products mainly includes: crushing-grinding-air pollution from dust in the screening process, noise pollution caused by mechanical operation, The asphalt fume produced during the kneading and molding process pollutes the atmosphere, and some also pollutes the surface water by the cooling water. The production process of graphite carbon block has a serious impact on the environment. It is necessary to be cautious when making such EIA reports, and pollution prevention measures must be in place.
Graphite carbon block is a conductive material for electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces.
It can withstand high temperatures and has a small coefficient of thermal expansion. It has a relatively small resistivity, which can reduce the loss of electrical energy. With a small porosity, the electrode in the heated state can be oxidized slowly. The higher mechanical strength prevents the electrode from breaking due to the influence of mechanical and electrical loads.
Electric current is smelted by the electric arc that is input into the furnace through the electrode. The electrode occupies a very important position in the entire electric furnace. Without it, the electric furnace cannot function. To make the electrode work normally at the temperature generated by the arc, it needs to have a high degree of oxidation resistance and conductivity. This is only the electrode made of carbon material, because the carbon electrode can withstand up to 3500 ℃ The arc temperature only slowly oxidizes.
