炼铁厂煤粉输送过去采用螺旋泵。该设备对于制粉系统远离高炉喷吹站的武钢,经过十多年的生产实践证明,不能满足向高炉喷吹站输送煤粉的要求,是高炉喷吹量受到限制的一个环节;尤其是在高炉喷吹量越来越大的情况下,这个限制环节会更加突出。因此,要加以改造,使之能适应高炉大喷吹量的要求。 1.仓式泵输送系统的选择炼铁厂拥有四座大型高炉,目前高炉平均日产量在11000~12000t,四座高炉都喷吹煤粉,喷吹量已达50~60kg/t铁,个别高炉有时达70kg/t铁以上,每天的煤粉需要量在600~700t。在“七五”期
Ironworks pulverized coal transportation in the past using a spiral pump. The equipment for the milling system away from the blast furnace station Wugang, after more than 10 years of production proved that can not meet the requirements of blast furnace pulverized coal delivery, blast furnace injection is limited to a link; especially in the Blast furnace injection more and more circumstances, this part of the restrictions will be more prominent. Therefore, to be modified so that it can adapt to the requirements of blast furnace large injection. 1. Bunker pump delivery system selection Ironworks has four large blast furnace, the current blast furnace average daily output of 11000 ~ 12000t, four blast furnace are pulverized coal injection has reached 50 ~ 60kg / t iron, individual blast furnace sometimes Up to 70kg / t iron, the daily requirement of 600 ~ 700t pulverized coal. In the “seven five” period
