本钢炼铁厂360m2烧结机1#、2#风箱翻板采用双轴双板翻板式蝶阀,结构简单,但在生产中易堵,堵后处理难、使用寿命短,很难控制适宜的烧结点火负压。通过对烧结机1#、2#风箱翻板的改进,彻底解决了点火炉膛内微压操作条件下,翻板式蝶阀堵料及堵料后阀门开、关失效的问题,同时也灵活控制了烧结点火负压,降低烧结煤气消耗。
Burnishing Machine 360m2 sintering machine of Benxi Iron and Steel Mill 1 #, 2 # bellows flap using biaxial double plate flap butterfly valve, the structure is simple, but easy to block in the production, blocking processing difficult, short service life, it is difficult to control the appropriate sintering Ignition negative pressure. Through the improvement of the sintering machine 1 #, 2 # bellows flap, completely solve the ignition chamber under the conditions of micro-pressure operation, the flap-type butterfly valve plugging material and blocking the valve after the opening and closing failure, but also flexible control of the sintering ignition Negative pressure, reducing the consumption of sintered gas.
