Graphite Electrodes applied in Foundry Industries

While applying graphite electrodes in foundry industries, it is mainly used in high-temperature process functions like smelting and refining metals, etc. Graphite electrodes can be applied on cast metals like iron and steel, as well as non-ferrous metals like brass, aluminium etc. Through conducting electrical energy in electric arc furnaces, graphite electrodes find use in foundries melting scrap metal or raw materials. Normally, the heat can reach a very high temperature which is enough to melt steel, iron, and other alloys. To get defined products, foundries featuring graphite electrodes produce alloys by melting base metals with other materials. The temperature of heat has been controlled, while graphite electrodes can work to precisely melt and mix the metals resulting in certain quality requested alloys.

 

Besides electric arc furnaces, graphite electrodes can be found in ladle furnaces where molten metal is further refined to adjust chemical composition. This procedure usually works for removing impurities or adding alloying elements. The supplementary heating always needs to keep the molten metal's temperature sufficient for refining. When the production of cast iron from scrap and pig iron, cast iron foundries apply graphite electrodes in electric arc furnaces. During the process of casting, the motel state is necessary to maintain stability, the generated heat melts the raw materials. This is used in the production of cast iron items for more efficiency.

 

Similar to graphite electrodes, graphite crucibles and molds also can be utilized as the component of melting materials. Due to the features of resistance to high temperatures and excellent thermal conductivity, graphite crucibles are a great item for melting some metals, like gold and silver.
