During the past two and a half years, lining lives of LD converters in Chinahave markedly increased with everal ampaigns exceeding 2000 heats. The averageLD lining life of the Capital Iron and Steel Company has surpassed 1000 heats.Improving the quality of refractory materials used has played a decisive role inthis increase. It has been proved hat natural dolomite and magnesitic dolomite are suitableraw materials for LD lining; the technical properties of bricks ade from them arequite satisfactory and high lining life can be achieved. A two-stage calcination process has been dopted or the preparation of highpurity dolomite (or magnesitic dolomite) clinker, by which the sintering tempera-ture can be owered 100--200℃. The clinker thus produced possesses uniform com-position and structure as well as improved ydration-resistant and slag-resistant pro-perties. Tar-impregnated burnt brick and tar-impregnated tempered block based n ighpurity clinkers have been developed for zoned lining and considerable increase inLD lining life has been attained. ased on the study of the wear mechanism of LD refractories by slags, it ispostulated that the process consists of ecarburization followed by chemical cor-rosion, which proceeds in two stages-attack by the initial acidic slag and then t-tack by the high ferrous slag at high temperatures. Slag resistance tests have shownthat synthesized magnesitic lomite xhibits superior resistance to both acidic andferrous-bearing slags.

近两年多来,我国转炉炉龄有显著提高,已有若干超过2000炉的炉役.首钢的平均炉龄已在1000炉以上.改善炉衬材料质量,对提高炉龄起决定性作用. 原料采用天然白云石和镁质白云石.实践说明:这类原料是制造转炉炉衬的适当材料,砖的性能可以满足要求,可以获得高炉龄. 采用二步煅烧法制备纯度较高的白云石和镁质白云石熟料,能降低烧结温度约100—200℃.熟料组成和结构均匀,抗水化和抗渣蚀性能大为改善. 以这种高纯熟料为基础,发展了烧成油浸砖和轻烧油浸砖,实行综合砌炉,炉龄可以大幅度提高. 根据转炉炉渣对炉衬材料侵蚀机理的试验结果,认为炉衬损毁过程首先是碳的氧化,脱碳后主要是化学侵蚀.基本上可以分为两个阶段.即初期酸性渣侵蚀和后期高温下高氧化铁渣的侵蚀.抗渣试验表明,合成镁质白云石对酸性渣和高铁渣的抗侵蚀性都很好.

Chemical composition, mineral constitution and properties of hydration of the oxygenconverter slag were investigated by chemical analysis, petrographic technique, XRD, DTAand physical testings. The minerals identified are tricalcium silicate, dicalcium silicate and its phosphorouscontaining solid solution, dicalcium ferrite, RO-phase, free lime and some amount of alumi-nate, aluminoferrite, fluor apatite, fluorspar, and metallic iron. The quality of the slag was graded by its content of tricalcium silicate and free lime.When the steel slag has a content of tricalcium silicate>40% and that of free lime<3%,it can be ground together with gypsum to produce qualified steel slag cement. Compressivestrengths of 50~60N/mm~2 and 30~40N/mm~2 have been obtained from slags containing tri-calcium silicate 50~55% and 40~46% respectively.

本文主要阐述氧气转炉钢渣试制水泥的若干问题。用化学分析、岩相分析、X射线衍射分析、差热分析测定了钢渣的化学成分、矿物组成和水化性能,并进行了各主要矿物的理论计算以及钢渣水泥的物理力学性能的测定。 转炉渣的主要矿物为硅酸三钙、硅酸二钙及其含磷固溶体、铁酸二钙、RO相、游离石灰以及其含铁固溶体,此外,有少量的铝酸盐、铁铝酸盐、氟磷灰石、萤石、金属铁粒等。 转炉渣的质量可由硅酸三钙和游离石灰量大体鉴别,以便分级管理和充分利用。对于硅酸三钙含量在40%以上,游离石灰含量在3%以下的钢渣可配以一定量的石膏磨制成钢渣水泥。当钢渣中硅酸三钙含量达50~55%时,其钢渣水泥的28天抗压强度可达50~60N/mm~2;含量在46~50%时,28天抗压强度可达40~50N/mm~2;含量在40~46%时,28天抗压强度可达30~40N/mm~2。

The crystal structures of the compositions in the converter slag at different temperatures are studied. This is of great significance to the appropriate choice of the technology for slag forming and to the production of slag cement.

本文利用X射线高温衍射技术探讨了转炉炉渣成分的晶体结构随温度的不同而发生变化的规律.这对选择合理的造渣工艺,研制纲渣水泥等有重要意义.
