我厂六吨电弧炉,主要冶炼高锰钢(ZGMn13)在还原期加入大量锰铁。过去习惯的方法,是将锰铁烘烤700~800℃,氧化末期,运上炉前操作平台,还原开始,工人要冒着高温把20%(约1400~1600公斤)烤红的锰铁投进炉内,确实劳动强度大,体力消耗多,特别是高温季节,劳动条件相当恶劣。广大炼钢工人,在厂党委的关怀下,研制成一种铁合金简易加料器,结构见下图。
I plant six tons of EAF, the main high-manganese steel smelting (ZGMn13) in the reduction period by adding a lot of ferromanganese. In the past, the method used to roast ferromanganese is 700-800 ° C, and the end of oxidation is transported to the operating platform in front of the furnace. At the beginning of the reduction, the workers should braze the ferromanganese cast iron 20% (about 1400-1600 kg) Into the furnace, really labor-intensive, physical exertion and more, especially in the hot season, working conditions are quite harsh. The majority of steel-making workers, under the care of the factory party committee, developed a simple ferroalloy feeder, the structure shown below.
