Technical Development of EAF Steelmaking - Graphite Electrode Manufacturer

-
图片
The Technical Development of EAF Steelmaking   has a history of about 100 years. Although always facing the challenges and competition of several other steelmaking methods, especially the impact of high-efficiency oxygen converter steelmaking, the proportion of steel production in electric arc furnace steel production in the world's total steel output continues to rise year by year. Electric arc furnace steelmaking relies on graphite electrodes to generate electric arc, which converts electric energy into thermal energy in the arc light. Steelmaking method of melting furnace charge and removing impurity components such as sulfur and phosphorus, and then adding required elements (such as carbon, nickel, manganese, etc.) to smelt various steels or alloys with different properties. Furnace temperature can be accurately controlled with electric energy heating, which produces less high-temperature exhaust gas, and the thermal efficiency of electric arc steelmaking fur

Construction of Wear-Resistant Refractory Plastics  at the water-cooled air chamber. Due to its special design and construction, the following points should be paid attention to in the construction of refractory plastics for water-cooled air chambers:   RS High Quality Plastic Refractory (1) The surface of the water-cooled pipe and pin is painted with asphalt paint, and the duct is covered with 2mm thick ceramic fiber paper. (2) Refractory plastics must be driven at one time, the thickness exceeding the standard shall be excavated, and the thickness less than 45 ° shall be excavated to make up. However, the plastic must be compacted, and there must be no voids or cavities. (3) Leave an expansion joint at an interval of 600mm × 600mm to avoid irregular cracks. Divide and frame construction during construction. The expansion joint is left in the middle of the tube and cut out with a knife. The thickness is half of the refractory plastic. It is also necessary to use a 3mm ve
