本钢有三座120t大型转炉,年产钢200万t。生产中每天向大气中排放大量煤气,不仅污染环境,而且浪费大量能源。 为此,该公司对煤气净化系统又进行了改造,还从西德引进了先进的磁氧分析仪,炉口微差压自动调节装置和微机自动控制装置,特别是对控制煤气回收中开关用的“三通阀”进行了改造和修理,达到了氮气压力在0.35MPa的情况下能够开关自
Bengang has three 120t large converter, with an annual output of 2 million tons of steel. A large amount of gas is emitted into the atmosphere every day in production, which not only pollutes the environment but also istes a lot of energy. To this end, the company has carried out the gas purification system has been transformed, but also from the West introduced advanced magnetic oxygen analyzer, automatic differential pressure regulating device and micro-computer automatic control device, especially for the control of gas recovery switch Of the “three-way valve” was modified and repaired, reaching a pressure of 0.35MPa in the case of nitrogen can switch
