现在转炉炼钢一股均采用化铁炉铁水生产,用化铁炉铁水需建化铁炉并多耗燃料,如能普遍采用热装高炉铁水,则可节约基建投资及生产费用。马鞍山钢铁公司在转炉热装方面作过很多工作,现在已有二个转炉车间采用铁水热裝。铁水成分含矽1～1.5%,含磷0.7～1.2%,含硫0.05%。高炉的有效容积为70～255立方米。1957年马钢曾建两座0.5吨小转炉,当时即采用高炉铁水热装生产,供铁水的炉子系70～80立方米的小型高炉,高炉铁水用5吨铁水缶装盛,置于窄轨火车小平板车上,运至转炉车间用吊车吊装入炉,尚能满足生产要求。1959年5月马钢一炼钢厂三车间投入生产,车间原设计6吨直筒型转炉,后改为3吨涡鼓型转炉(现在实际装5吨),亦采用热装高炉铁水,用普通的6～10吨铁水缶置于大平板车上,每个平板车可放置二个铁水缶,缶的外围在平板车上加角铁栏杆,以
Now a converter steelmaking furnace are used iron production, use iron furnace iron and iron to be built and consume more fuel, such as hot blast furnace hot metal can be used, you can save capital investment and production costs. Maanshan Iron and Steel Company has done a lot of work in the converter hot-wear, now has two converter workshop hot metal hot-fix. The hot metal contains 1 to 1.5% of silicon, 0.7 to 1.2% of phosphorus, and 0.05% of sulfur. The effective volume of blast furnace is 70 ~ 255 cubic meters. In 1957, Magang once built two small transformers of 0.5 tons. At that time, the hot blast furnace was used to produce the hot blast furnace hot metal. The furnace for molten iron was a small blast furnace of 70 to 80 cubic meters. The blast furnace hot metal was filled with 5 tons of molten iron, Rail train small flat car, transported to the converter workshop crane hoisting furnace, still able to meet the production requirements. In May 1959, the first workshop of the Masteel Steel Mill was put into production. The workshop originally designed a 6-ton straight-type converter and was later converted into a 3-ton scroll converter (now actually loaded with 5 tons). Hot-blast blast furnace hot metal Of 6 to 10 tons of molten iron placed in a large flatbed car, each flatbed can be placed two hot metal 缶, 缶 outside the flatbed plus angle iron railings to
