In the face of the "new normal" of China's steel industry, a variety of steelmaking auxiliary materials, such as pre-melting refining slag, can reduce costs and increase efficiency by accelerating energy saving in the steelmaking industry and effectively relieve the financial pressure of enterprises, which is very important for steel enterprises in difficulties. Iron and steel enterprises mainly from the promotion of iron and steel industry cycle economy development and improve smelting technology two major aspects, so that the development of steel and steel industry in line with the long-term goal of sustainable development, and the implementation of strict industry exhaust emission reduction self-discipline principle.
The pre-melting slag is also called the pre-melting slag or the pre-melting aluminum calcium slag. It has uniform chemical composition, low melting point and fast melting speed, which can shorten the smelting time. No fluorine, no erosion of furnace lining and ladle; Compact structure, non-absorbent, easy to store storage bin; Because the phase is stable and the slag is formed fast, it can reduce the dust pollution to the steel plant and stabilize the refining process. No hydrogen, nitrogen, carbon and other impurities, to improve the quality of steel. It has been proved by users that the curve function of the stability of the fused calcium aluminate produced by Huaxin Refining Slag Company with time is almost a straight line. To avoid the middle and low grade products (sintering products, cupola products) wavy, sawtooth curve function to the metallurgical production brought about a lot of inappropriate phenomenon.
