摘要
为解决高炉铁水含钛无法进行硅钢冶炼问题,在4000m3高炉上进行了炉前铁水脱钛工业试验研究。试验条件:使用自行开发的脱钛喷吹小车装置、碱性氧化物烧结矿返矿进行炉前脱钛,喷吹量为1%,喷吹位置为铁水沟前端。试验结果表明,铁水脱钛率为56.9%,脱硅率为41.2%,铁水从高炉到炼钢脱硫站的温降为140℃,属正常温降水平,但由于烧结矿中含硫使铁水硫含量有升高趋势。此外,整个脱钛工业试验无扬尘和喷溅,符合炉前环保和安全要求。
In order to solve the problem of high titanium content in hot metal of blast furnace and unable to produce silicon steel,the industrial test of titanium removal from hot metal was carried out in 4000m3 blast furnace.The test conditions are as follows:using the self-developed Ti removal injection car device and returning alkaline oxide sinter to remove Ti in front of the furnace,the injection amount is 1%,and the injection position is at the front end of the iron ditch.The results show that the rate of Ti removal and Si removal is 56.9%and 41.2%respectively,and the temperature drop of hot metal from blast furnace to desulfurization station is 140℃,which is a normal temperature drop level.However,the sulfur content of hot metal tends to increase due to the S content in sinter.In addition,there is no dust and splash in the whole industrial test,which meets the requirements of environmental protection and safety in front of the furnace.
