摘　　要：对影响AOD炉冶炼300系不锈钢周期的因素进行了探讨,并针对各影响因素提出了相应的缩短冶炼周期的措施。缩短AOD炉冶炼周期是降本增效的途径之一,影响AOD炉冶炼300系不锈钢周期的主要因素包括热值不足,加入冷料过多、生产协调性欠缺,设备方面的除尘系统、余热锅炉、下料系统。提出了增加母液供应、原料采购选择、高镍铁水生产要求三个提高入炉原料热值的措施,提升配气人员技术水平、操作制度、现场管理三个生产协调问题解决办法以及除尘系统、余热锅炉系统、下料管改造等三个设备改造方法。期望通过提出的九项解决措施缩短AOD炉冶炼周期,助力钢厂降本增效。The article explores the factors that affect the smelting cycle of 300 series stainless steel in AOD furnace,and proposes corresponding measures to shorten the smelting cycle for each influencing factor.Shortening the smelting cycle of AOD furnace is one of the ways to reduce costs and increase efficiency.The main factors affecting the smelting cycle of 300 series stainless steel in AOD furnace include insufficient calorific value,excessive addition of cold materi-als,lack of production coordination;dust removal system,waste heat boiler,and feeding system in terms of equipment.Three measures have been proposed to increase the calorific value of raw materials in the furnace,including increasing the supply of mother liquor,selecting raw material procurement,and meeting the production requirements for high nickel molten iron.The solutions to three production coordination problems,including improving the technical level of gas distribution,operating systems,and on-site management,as well as three equipment transformation methods,including dust removal system,waste heat boiler system,and discharge pipe transformation.It’s expected to shorten the AOD furnace smelting cycle and assist steel mills in reducing costs and increasing efficiency through the nine proposed solutions.
