Operation Practice of Shouqin No.1 Blast Furnace in the Late Stage of Service
The No.1 blast furnace of Qinhuangdao Shouqin Metal Materials Co.,Ltd.started operating in 2004 and entered the later stage of furnace service after 13 years of operation.Factors such as aging of blast furnace equipment,deformation of furnace shape,and damage to cooling equipment affect the stability and smooth operation of the blast furnace.Meanwhile,influenced by the market,there have been significant changes in the raw materials used in blast furnaces,with a decrease in grade and an increase in slag ratio.In order to adapt to the smelting of late stage blast furnaces,measures such as strengthening raw material and fuel management,iron production management,rational optimization of upper and lower operating systems,and strengthening the maintenance of furnace body and hearth longevity have been taken to ensure the stable and smooth operation of the blast furnace.
