氧气顶吹转炉炼钢耗电量最大的是除尘通风机,约占炼钢车间总耗电量的2/5.我厂炼钢车间为15吨转炉三座,通风机用低效率8-18-12、16~#离心通风机,电机为6千伏300千瓦.过去通风机从开炉吹炼到停炉止,一直处在负荷状态下工作,这样运行浪费电能.经测算,除尘风机对转炉生产真正起净化除尘作用的利用率低于60％. 为了节省电能,对除尘风机的进口蝶阀进行了改造,分别在两座(1~#与2~#炉)转炉风机蝶阀上安装了控制装置.经2个月的试验共测试25次,通过2585炉考验,效果比较好.到目前为止共使用一年十个月,工作正常,共节电62万度. 对蝶阀负荷自动控制要求:转炉在吹炼时,除尘风机进口蝶阀应打开,除尘系统起净化
Oxygen top blowing converter steelmaking power consumption is the largest dust fan, accounting for about 5% of the total power consumption of steelmaking plant. I plant 15 tons of steel plant converter three, the fan with low efficiency 8-18 -12,16 ~ # centrifugal fan, the motor is 6 kilovolts 300 kilowatts. In the past fan blowing furnace to stop furnace only, has been at work under load, so running waste of electricity. After calculation, dust fan pair In order to save electric energy, the import butterfly valve of the dedusting air blower has been reformed, installed on two butterfly valve (1 ~ # and 2 ~ # furnace) converter fan butterfly valve respectively After 2 months of testing a total of 25 tests, 2585 furnace test, the effect is better. So far a total of ten months a year, working properly, a total of 620,000 power-saving. Automatic butterfly valve load control requirements: Converter blowing, dust fan inlet butterfly valve should be opened, the dust removal system from the purification
