本文介绍的是对苏钢原有83.5m~3高炉进行改造性易地大修设计。根据苏钢意见,在仍采用现有300m~3/min风机的基础上合理调节炉型,在保持斜桥布置基本不变的基础上又要求铁口标高提高400～500mm的前提下设计一座有效容积为90～100m~3高炉。并要求在矿石含铁品位在58%(去CaO)、熟料率85%、喷煤粉60～80kg/t铁、喷油～20kg/t铁的条件下获得利用系数2.0t/m~3·d、综合折算焦比550kg/t铁的较先进指标。现将该项设计特点作一简介,供同级高炉技术改造时参考。一、炉体新高炉在调整炉型的同时将有效容积扩大到94m~3,炉缸直径2800mm,炉腰直径3600mm,Hu/D=3.64。在保持斜桥布置
This article describes the original Soviet Union Steel 83.5m ~ 3 blast furnace easy to overhaul design. According to Su-Steel’s opinion, while still using the existing 300m ~ 3 / min fan on the basis of a reasonable regulation of the furnace, while maintaining the basic layout of the inclined bridge on the basis of the requirements of the iron mouth elevation 400 ~ 500mm under the premise of an effective design Volume of 90 ~ 100m ~ 3 blast furnace. And requires that the utilization factor 2.0t / m ~ 3 be obtained under the condition of 58% (CaO removal), 85% clinker rate, 60 ~ 80kg / t iron pulverized coal, and ~ 20kg / · D, the integrated conversion coke 550kg / t iron more advanced indicators. Now the design features for a brief introduction for the same level of technological transformation of blast furnace reference. First, the new furnace blast furnace furnace while adjusting the effective volume will be expanded to 94m ~ 3, hearth diameter 2800mm, waist diameter 3600mm, Hu / D = 3.64. Stay in a skewed bridge layout
