侧吹转炉在冶炼操作过程中,为了避免鼓风设备频繁的停风操作,一般是采用蝶形放风阀切断放风。但是,由于放风量大,雨产生强大的噪声,并使风机负荷与电耗都增加,机械振动也加大。为此,苏州钢铁厂对风阀进行了改革。经过一年多时间的生产实践证明,得到了较好的消音效果。改进措施是:取消原进入转炉前的蝶形放风阀,在手动调节控制的反板阀上安装皮带盘、配上减速箱、马达、限位开关等。为 Side blowing converter in the smelting operation, in order to avoid the frequent blasting blasting equipment operation, the butterfly valve is generally used to cut off the wind release. However, due to the large amount of wind, rain produces strong noise, and fan load and power consumption are increased, mechanical vibration also increased. To this end, Suzhou Iron and Steel Plant on the valve reform. After more than a year of production practice has proved that get better noise reduction effect. Improvement measures are: to cancel the butterfly valve before entering the converter, in the manual control of the anti-plate valve installed on the belt plate, coupled with gear boxes, motors, limit switches. for
