How does a large electric arc furnace work?

/ / news

An electric arc furnace is an electric furnace that smelts ores and metals using the high temperature generated by an electrode arc. When the gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc zone is above 3000 °C. For metal smelting, the electric arc furnace is more flexible than other steel making furnaces, and can effectively remove impurities such as sulfur and phosphorus. The furnace temperature is easy to control, and the equipment occupies a small area.

Beijing Great Pack Materials Co., Ltd. specializes in the research, development and sales of heat-resistant sleeve and other high-temperature materials. Fiberglass Sleeve, alias: fireproof pipe, high temperature cable protection sleeve. Block molten iron from splashing, and will not be damaged by high temperature and flame. The high temperature resistant fireproof jacket has an advanced two-layer combination: wear-resistant-flame-retardant layer, heat-insulation-water-proof and fire-proof layer, fire-resistant layer, even a single layer in use. If the second layer is burnt through, the second layer can also be effectively protected, which will save time for the next maintenance. Hoses, cables and pip
