瑞典铁合金制粒技术在世界上享有一定的声誉,发展较早,技术成熟。1.粒化的必要性炼钢要求铁合金具有一定的块度,以缩短加入钢液中的熔化时间,使合金元素分布均匀。铁合金的粒化工业就是根据炼钢工业对铁合金的要求逐渐发展起来的。同时,粒化对铁合金生产厂也是有益的:通常铁合金生产厂生产的铁合金(如硅铁、铬铁等),铸,成大锭,须人工或机械破碎才能运出,这样合金损失很大、工人劳动强度大、粉尘大,
Sweden ferroalloy granulation technology in the world enjoy a certain reputation, the development of earlier, mature technology. 1. The need for granulation Steelmaking requires ferroalloy has a certain degree of lumps, in order to shorten the melting time added to the molten steel, the alloying elements are evenly distributed. Ferroalloy granulation industry is based on the steel industry’s requirements for ferroalloy gradually developed. At the same time, granulation is also beneficial for ferroalloy production plants: ferro-alloys (such as ferrosilicon, ferrochrome, etc.) produced in ferroalloy production plants are generally cast or made into large ingots which must be manually or mechanically crushed to be shipped out so that the alloy suffers great losses, Labor intensity, dust big,
