土法坩堝煉鋼是利用圖1所示的地爐煉的。地爐可以連續使用1—2星期,每只坩堝可用2—3次。以后还可用以熔化低溫合金。使用的原料是廢鋼。燃料以白煤为主,辅以木炭。可以煉出碳素鋼和不锈钢。
Induction crucible steelmaking is the use of floor furnaces shown in Figure 1. The furnace can be used continuously for 1-2 weeks, each crucible available 2-3 times. Later used to melt the cryogenic alloy. The raw material used is scrap. White coal-based fuel, supplemented by charcoal. Can be carbon steel and stainless steel.
