近年来,国内炼铁技术改造采用了一些新措施,这些新措施大都投资少,回收期短,经济效益显著,在技术上具有可行性,值得有关企业借鉴和推广。 1.利用高炉冷却水落差发电马钢一铁厂300米~3高炉的冷却水消耗量约800吨/时,从集水箱至排水沟的自然落差 In recent years, some new measures have been adopted in the technological transformation of domestic ironmaking. Most of these new measures have less investment, short payback period and significant economic benefits. They are technically feasible and worth learning and promotion from relevant enterprises. 1. The use of blast furnace cooling water power generation Maanshan Iron and Steel Works Iron Works 300 m ~ 3 blast furnace cooling water consumption of about 800 tons / h, from the catchment to the natural drainage gap
