Blastfurnace hot air valve, combustion valve and reverse flow rest valve, and swap with the original conventional hot air valve
The tension and deterioration of water resources is an urgent global problem,so saving water and saving energy has become a common trend in the world. Asfar as blast furnace equipment is concerned, the cooling water consumption of conventional hot air valve is large and the energy consumption is large, which becomes the key to energy saving and consumption reduction of blast furnace.Shangfa valve Co., Ltd. actively tracks the latest technology of blast furnace equipment in the world, adheres to the research and development of high-tech products for a long time, and cooperates with iron and steel equipment research colleges and steel enterprises to develop micro-water energy-saving hot air valve. Through the new design, the cooling water of the hot air valve has been greatly reduced, and the loss of hot air has been reduced. It has become the first choice of key equipment for energy saving and consumption reduction of blast furnace, and won the national invention patent.
Four mature patented technologies of conventional lining hot air valve are applied.(fully covered with amorphous ceramic refractories, asymmetric water cavity structure of valve body, composite protection of valve plate, full floating sealing device of valve stem)
