由于精品钢及机械制造业高性能构件生产的需求,对低杂质精炼铁合金的需求逐年增加。为缩短工艺流程,降低能耗,减少渣量及硅铬合金中间产品及含有六价铬废弃物的产生,通过以氧代电,开发出一种新型精炼铁合金生产工艺和装备,生产低杂质的精品合金,降低冶炼综合能耗,减少精炼工艺的排渣量,杜绝生产环节中产生危险废弃物,实现工艺过程渣、尘循环利用,提高了产品质量,降低了生产成本,满足了精品钢及高性能构件生产的需求。
Demand for low-impurity refined ferroalloy has been increasing year by year due to the demand for high-performance component production in fine steel and machinery manufacturing. In order to shorten the process, reduce energy consumption, reduce the amount of slag and chromium-chromium intermediate and hexavalent chromium waste generated by oxygen generation, to develop a new type of refined ferroalloy production technology and equipment to produce low-impurity Quality alloy, reduce the comprehensive energy consumption of smelting, reduce the amount of slagging in the refining process, eliminate hazardous wastes in the production process, realize the recycling of slag and dust in the process, improve the product quality and reduce the production cost, meet the requirements of fine steel and Demand for high performance component production.
