There exists a certain kind of difficulty to smelt the vanadium-bearing titanomagnetite in a conventional blast furnace. The overwhelming important condition to smelt such kind of the magnetite is to choose reasonable burden structure so as to control the reduction of TiO_2. The result obtained from the research works and the praetices e.g. the burden reduction in the lump zone, the smelting at high temperature, the forming of the first slag as well as the reaction of the slag with iron showed that...

There exists a certain kind of difficulty to smelt the vanadium-bearing titanomagnetite in a conventional blast furnace. The overwhelming important condition to smelt such kind of the magnetite is to choose reasonable burden structure so as to control the reduction of TiO_2. The result obtained from the research works and the praetices e.g. the burden reduction in the lump zone, the smelting at high temperature, the forming of the first slag as well as the reaction of the slag with iron showed that the smelting properties of the sinter can be improved by addition of SiO_2 and adding some fluor-spar, ferriferous manganese ore or some irreducible ores.

利用普通高炉冶炼高钛型钒钛磁铁矿有很大的难度。选择合理的炉料结构,控制高含量TiO_2的还原,是冶炼该矿石的首要条件。炉料在块状带的还原、高温还原熔化、初渣的生成以及高温带渣铁反应的研究结果和生产实践都表明:提高炉料中SiO_2含量,适当配加萤石、铁锰矿或配加部分难还原的矿石都可以改善钒钛烧结矿的冶炼性质。

A coating material for the lining of torpedo ladle was made by using special grade bauxite,corundum powder, sili-con carbide and silica fine powder as raw inaterial and composite phosphate as binder added with 9 % water. The servicelife of the coating material in the middle and bottorn part of the torpedo reaches 40d and 17 d in the upper part beforethe first slag removing (3~5 d for the traditional brick lining). The whole service life in the upper part of the vessel isinore than 30 d. So the coating...

A coating material for the lining of torpedo ladle was made by using special grade bauxite,corundum powder, sili-con carbide and silica fine powder as raw inaterial and composite phosphate as binder added with 9 % water. The servicelife of the coating material in the middle and bottorn part of the torpedo reaches 40d and 17 d in the upper part beforethe first slag removing (3~5 d for the traditional brick lining). The whole service life in the upper part of the vessel isinore than 30 d. So the coating material has ged wear and corrosion resistance.

以特级矾土、刚玉粉、碳化硅、SiO2微粉等为主要原料,复合磷酸盐为结合剂,外加水9%,制成喷涂料,喷涂于铁水罐内村。铁水罐中、下部(铁水区)使用寿命达40d;其上部(结渣区)17d后第一次除渣(传统砖衬3~5d除一次渣),使用寿命30d以上。该材质有效地抵抗了渣、铁水的冲刷与侵蚀。

The factors affecting the increasing of sulfur in liquid metal at the first slag off from converter were analyzed theoretically and practically, The causes of increasing sulfur in liquid metal and the appropriate way to deal with it were found out, According to Grey System, the main factors were the original sulfur content of the hot metal and the sulfur distribution coefficient between slag and molten metal, Under present production conditions, the present sulfur distribution coefficient of LYSW's...

The factors affecting the increasing of sulfur in liquid metal at the first slag off from converter were analyzed theoretically and practically, The causes of increasing sulfur in liquid metal and the appropriate way to deal with it were found out, According to Grey System, the main factors were the original sulfur content of the hot metal and the sulfur distribution coefficient between slag and molten metal, Under present production conditions, the present sulfur distribution coefficient of LYSW's converter is low, so the increasing sulfur can not be avoided, Optimizing the component of slag and improving the sulfur distribution coefficient are a practical way to avoid increasing sulfur.

结合理论与实践分析了影响略钢转炉炼钢“一倒回硫”的因素 ,找出了回硫原因 ,并提出了相应对策 .灰色系统理论分析表明 ,影响“一倒回硫”的主要因素是铁水初始含硫量 ( [S%]0 )和硫的分配系数 ( LS) .在略钢转炉现行生产条件下 ,硫的分配系数偏低是产生“一倒回硫”的主要原因 .故优化炉渣成分 ,提高转炉冶炼硫的分配系数是避免“一倒回硫”的切实可行途径
