摘要
河钢集团邯钢新区系邯钢东区退城整合搬迁项目,受山区地形及土地面积限制,该项目采用紧凑式布局,高炉到转炉最近距离450 m,吨钢占地面积仅0.3 m^(2),铁钢界面采用汽车“一罐到底”模式进行铁水驳运,铁水罐受铁完毕后10 min即可拉到炼钢生产,并运用了数字、物联网等新技术加以辅助,经过投产以来的改进优化,新区铁水罐周转率达到7.0次/日、进炼钢铁水温度1440℃、“一罐到底”比例99%,较搬迁前分别提高4.0次/日、98℃、39百分点;铁水温降降低到82℃,较搬迁前减少81℃,界面热量损耗大幅降低,为炼钢工序增钢降耗创造了有利条件,符合国家节能减排的理念,对行业“双碳”战略具有一定借鉴意义。
Hangang New Area is an integrated relocation project of Hangang East District.Limited by the mountainous terrain and land area,the project adopts compact layout,the nearest distance from blast furnace to converter is 450 m,and the area of tons of steel is only 0.3 m^(2).The iron and steel interface adopts the“one tank technology”mode using vehicle for the transportation of hot metal,and the hot metal tank can be pulled to steelmaking production in 10 minutes after receiving hot metal.And the use of digital,Internet of Things and other new technologies to assist,after the improvement and optimization since the operation,the new district hot metal tank turnover rate reached 7.0 times/day,the steelmaking hot metal temperature of 1440℃,the proportion of“one tank technology”99%,which respectively increased 4.0 times/day,98℃,39 percentage points higher than before the relocation.Hot metal temperature decreased to 82℃,81℃lower than that before the relocation.The significant reduction in interface heat loss has created favorable conditions for increasing steel and reducing consumption in the steelmaking process,which is in line with the national concept of energy conservation and emission reduction,and has certain reference significance for the“dual carbon”strategy of the industry.
