The production process, method and use of graphite blocks for sale

The production process of graphite blocks for sale is roughly as follows:

Raw materials (petroleum coke, coal, etc.) crushing-grinding-sieving-ingredients-kneading (a mechanical stirring process in which melted medium temperature pitch is added to the dry material and maintained at a certain temperature by steam heating)- —Molding—The impact on the environment during the production process of the finished product mainly includes: crushing—grinding—the air pollution caused by the dust in the screening process, the noise pollution generated by the mechanical operation, and the asphalt smoke generated during the kneading and molding process. Atmospheric pollution, and some of the surface water pollution caused by cooling water, etc. The production process of graphite blocks for sale 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 blocks for sale are conductive materials used in 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.
