全量铁水“三脱”必要性的探讨

Discussion on necessity of hot metal full pretreatment

分析了铁水预处理功能的演进,认为其实际功能已超越了原来对质量调控的范畴,逐渐演进为工序及工序间的质量、能量以及协调缓冲的调节器。从6个方面对全量铁水进行"三脱"的必要性进行了探讨,指出新建的大型钢厂全量铁水"三脱"的模式是建立高效低成本的洁净钢生产平台、增强产品竞争力、推动我国钢铁工业快速高效发展的必然之选。

The evolution of the hot metal pretreatment functions is analyzed and its considered that actual function of this process has already overpassed its originally designed limit of quality control and evolved step by step into an adjustor for coordinating and buffering the quality and energy in between processes. The necessity of ＂tri-de＂ for full hot metal is elaborated from six aspects and its pointed out that development of a new mode of ＂tri-de＂ of full hot metal in a large scale integrated steel work means to establish a platform for production of the clean steels high efficiently and cost-effectively and its also an inevitable road for strengthening the competitiveness of the products and pushing forward the development of Chinas iron and steel industry in a high efficient way.
