土铁中硅、錳的含量几乎等于零,平均含量只在0.1左右。因此用土鉄在轉爐中炼鋼吹炼是一个很大的问題。沒有硅、錳第一期吹炼不起来,鉄水温度提不高,这就可能造成越吹铁水越凉的危險,是一个很不利的因素。毛主席經常教导我們应当善于把不利的东西变成有利的东西。土鉄硅、錳低,不能利用硅、錳的氧化来提高鉄水温度,可是,吹炼的时間却可以縮短。一般炼鋼时,吹去硅、錳的时間大約5分鐘左右,如果沒有硅、錳就可以省去这5分鐘。使
Soil iron in silicon, manganese content is almost equal to zero, the average content of only about 0.1. Therefore, it is a big problem to make steel blowing in the converter by using soil clay. There is no silicon, manganese can not blow the first phase of the boil water temperature is not high, which may result in the more the risk of blowing hot metal hot water is a very unfavorable factor. Chairman Mao often teaches us that we should be good at turning bad things into favorable things. Soil silicon, manganese low, can not use silicon, manganese oxidation to improve the water temperature, however, the blowing time can be shortened. General steelmaking, blown to silicon, manganese time about 5 minutes, without silicon, manganese can save this 5 minutes. Make
