  bof slag
A treatment process was developed when basic oxygen furnace slag (BOF slag) and hydrogen peroxide were used to oxidize 2,4-dinitrophenol from an aqueous solution.
      
BOF slag, final waste slurry from steel making plants, contains about 12.5% by weight of ferrous oxide.
      
In an acid solution, BOF slag can be dissociated to produce ferrous ions and react with hydrogen peroxide to produce hydroxyl radicals and oxidize 2,4-dinitrophenol.
      
Various factors critical to the oxidation of 2,4-dinitrophenol were studied, including hydrogen peroxide concentration, concentration of BOF slag, initial concentration of 2,4-dinitrophenol, and pH value of solution.
      
Experimental results proved that 100 mg/L 2,4-dinitrophenol and its oxidation intermediate could be totally decomposed within 60 min by 10 g/L BOF slag, 0.18 g/L hydrogen peroxide and pH 2.8 ± 0.2.

As regards the effect of the iron oxide content of molten slags upon desulphurization in iron- and steelmaking, different conclusions have been given in the literature: (1) pure iron oxide slag has a desulphurizing effect and gives a sulphur-distribution ratio of 3.6 at 1600℃; (2) variation of the iron oxide content of openhearth slags from 3 to 70% has practically no effect upon the sulphur-distribution ratio; (3) with electric furnace (or blast furnace) slags, the less the iron oxide content, the higher the...

As regards the effect of the iron oxide content of molten slags upon desulphurization in iron- and steelmaking, different conclusions have been given in the literature: (1) pure iron oxide slag has a desulphurizing effect and gives a sulphur-distribution ratio of 3.6 at 1600℃; (2) variation of the iron oxide content of openhearth slags from 3 to 70% has practically no effect upon the sulphur-distribution ratio; (3) with electric furnace (or blast furnace) slags, the less the iron oxide content, the higher the sulphur-distribution ratio; and (4) with less basic slags within a certain range of basicity, increase in the iron oxide content brings about an increase in the sulphur-distribution ratio. In the present paper, through calculations with the help of the sulphur-distribution ratio formula: (%S)/[%S]=2.56fs/γ_s--·(Σn+Σn_-)/n_(FeO) derived from the complete-ionization theory of slag constitution and with the introduction of activity coefficients, it has been shown that the above-mentioned four conclusions are not contradictory against one another, and between them there exists an intimate relation. They simply signify that under different conditions iron oxide exerts different actions, and all these different actions could be amalgamated and generalized under the same formula. On the assumption that SiO_2 is present as SiO_4~(4-)in the slag, the formula is not suitable for application to acid slags, while at the same time the effect of temperature upon the sulphur-distribution ratio needs further investigation. The formula has been used to evaluate the sulphur-distribution ratio of basic cupola and basic side-blown converter slags from data in actual practice, and the following resuits have been obtained: (1) desulphurization in the basic cupola practice has practically reached equilibrium; and (2) in basic side-blown converter practice, owing to the presence of gaseous desulphurization, the sulphur-distribution ratio found in actual practice is less than that calculated from the formula.

根据由炉渣完全离子化理論导出的硫分配比公式: (%S)/[%S]=(2.56fs)/(γ_s--)·(∑n_+∑n_-)/(nFeO),在充分引用活度系数的条件下,研究炉渣氧化鉄含量对脫硫的作用。文內采用三种碱度的炉渣进行了計算,結果証明文献內前人对FeO作用四种分歧的評价不是相互矛盾的,而相反地是有內在联系的;它們說明FeO在不同条件下显示不同的作用,而这些不同的作用都可用上列硫分配比公式統一地表示出来。最后,对該公式能否适用于碱性化铁炉及側吹碱性轉炉炉渣,以及对該公式存在的某些缺点和問題进行了討論。

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.

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.
