株洲机械修配厂用湖南高硫土鉄,不用矽鉄、锰铁和铝提温,不用苏打炉外脱硫,炼出了转炉合格钢,总脱硫率达88—90％以上。钢的含硫量一般在0.09％左右,最低达0.027％。含磷0.005％。株洲机械修配厂炼钢车间系今年7月开始筹建,边建设边生产,至10月全部球成。主要设备计有:1.5吨酸性D型转炉二台(因改为碱性缩小到1.2吨,由一台风量48M~3/分、风压2300公厘水柱(常用风压200—240毫米水银住)的高压离心鼓风机送风;3吨碱性化鉄炉二台,附有前炉及管式热风炉(热风温度200—300℃),用两台#8罗茨鼓风机并传送风(常用风压70毫米水住);3吨、5吨桥式超重机各一部。厂房面积840平方米。湖南大部分土铁硫高,矽、锰低,在冶炼工作上主要是去高硫和提高温度的问题。全厂职工在党的正确领导下,采取了分段去硫,层层防御的办法,对硫的斗争基本上取得了一些经验。在这次土铁炼成合格钢的斗争中,我们坚决地贯彻了冶金部的指示,不用苏打炉外脱硫,不用矽鉄、锰铁、铝提温。采取的措施如下:
Zhuzhou machinery repair plant with high-sulfur soil in Hunan, without silicon, ferromanganese and aluminum temperature, without baking soda outside the desulfurization, refining the converter qualified steel, the total desulfurization rate of 88-90%. Sulfur content of steel is generally about 0.09%, the lowest up to 0.027%. Phosphorus 0.005%. Zhuzhou Machinery Repair Factory steel plant started construction in July this year, while building production, to all of the ball into October. The main equipment includes: 1.5 tons of acid D converter (due to the basic reduced to 1.2 tons, from a typhoon 48M ~ 3 / min, pressure 2300 mm water column (commonly used pressure 200-240 mm mercury live ) Of the high-pressure centrifugal blower air supply; 3 tons of two basic boilers, with a former furnace and tube stove (hot air temperature 200-300 ℃), with two # 8 Roots blower and send the wind (commonly used wind Pressure 70 mm water); 3 tons, 5 tons of a bridge overweight machine each. Plant area of 840 square meters. Most of Hunan soil iron high sulfur, silicon, manganese low, mainly in the smelting work to high sulfur and increase Temperature issues.All workers in the factory under the correct leadership of the party, took a section of desulfurization, layers of defense approach, basically gained some experience in the struggle for sulfur.In this soil iron into the battle of qualified steel , We firmly implement the instructions of the Ministry of Metallurgy, without desulfurization outside the soda stove, without silicon, ferromanganese, aluminum to take the temperature to take the following measures:
