鞍钢炼铁厂在消化引进国外新型高温热风阀技术后,与秦皇岛冶金机修总厂合作,设计研制了我国第一代新型高温热风阀,并于1981年10月首次在鞍钢9号高炉上应用获得成功。该阀主要特性是,水圈冷却水为双进双出,冷却强度提高一倍;阀板的冷却水通道改为“蚊香”状,使流向更趋合理,阻力减小,水流速度由旧阀的0.27米/秒提高到0.69米/秒:阀柄和水圈捣打耐火材料,使热阻增大近三倍。生产实践表明,新型高
After digesting the introduction of a new type of high-temperature hot-blast valve technology in foreign countries, Anshan Iron and Steel Co., Ltd. cooperated with Qinhuangdao Metallurgical Machinery Plant to design and manufacture the first generation new high-temperature hot-air valve in China and applied for the first time in No.9 blast furnace at Ansteel in October 1981 success. The main features of the valve is that the water ring cooling water is double inlet and outlet, the cooling intensity is doubled; the cooling water channel of the valve plate is changed to “mosquito-coil” shape, the flow direction is more reasonable and the resistance is reduced; 0.27 m / s to 0.69 m / s: The valve stem and water ring ramming refractory material increases thermal resistance nearly threefold. Production practice shows that the new high
