This article describes a new process for the continuous decopperization of crude lead, which has been applied in the Shenyang Smelter since September 1974. The basic principle of the process and the structure of the furnace are described. The production practice, operational experience, principal technical indices and process improvements in the past five years are given in detail. The article further describes the following new propositions about the process. (1) There is no relationship between the copper content in decoppered lead and the lead content in the matte produced. Even when the Cu content in the decoppered lead is less than 0.08%, high Cu: Pb ratio matte can be produced. (2) The ratio be- tween sulfur and copper (S/Cu) in the charge should be 0.5 instead of 0.25. A ratio of 0.25 is not sufficient for the process. (3) In order to decrease the lead content in the matte and to raise the Cu: Pb ratio, it is necessary and reasonable to add some scrap iron to replace the lead in it. To judge the correct end point of iron addition is the crux of the process. The composition of the crude lead treated is as follows (%): 96-97.5 Pb, 0.8- 1.3 Cu, 0.3 As, 0.8 Sb and 0.2-0.5 S. The blast-furnace crude lead is charged into the furnace as hot liquid. Then 0.6-0.8% soda, 0.2-0.3% coke and 2% lead sulfide con- centrate are added. The decoppered lead is discharged from the end of furnace by syphoning. De- pending on the degree of aggregation, the matte and slag are discharged about once a day. After discharging the slag, scrap iron is added into the matte to replace the lead in it. The Cu content of the output lead is 0.05-0.08%, it may be cast into anodes directly for e1ectrolysis. Lead content of the tapped slag is<2%. The matte has a Cu: Pb ratio of 3-5 (average 4), and can be sent to the copper smelter to re- cover copper without additional treatment. The productivity of the furnace bed is 10-l2 t/m~2. day. The decopperization efficiency is about 95%. In the output lead the recovery of Pb is about 99%, Sb-80%, As-70%. The volatility of lead is 0.3-0.4%. Finally, it is pointed out that maintaining a S: Cu ratio of 0.5 is of importance to the decopperization and matte formation process and in the elimination of bloc- kage.

本文简要地叙述了沈阳冶炼厂的粗铅连续脱铜新工艺。文中就脱铜过程阐述了如下一些新的论点:脱铜铅含铜与产出的冰铜含铅(或铜铅比)无关。在脱铜铅含铜低于0.08%的同时,能够产出钢铅比较高的冰铜;炉料中的硫铜比应保持0.5,而不是0.25;为了降低冰铜含铅,提高铜铅比,向冰铜中加入铁屑置换其中的铅是必要的,合理的,准确地判断加铁过程的终点是这一操作过程的关键。

This paper summarizes the results of research and application of oxygen sensor with solidelectrolyte in molten steel since 1975. It indicates some key points for raising the rate of successfuldeterminations and signal stability. The reliability of the data obtained has also been identified inmany ways. In a study of electric furnace melting using oxygen sensors, it was found that the oxygenactivity in the bath before tapping and final deoxidation is closely related to the oxide inclusiongrade of the steel product, decreasing the oxygen activity before final deoxidation being advantageousto the cleanness of the product. By using aluminium for preliminary deoxidation, the reduction pe-riod in the furnace may be shorten considerably. Oxygen content changes in bottom oxygen-blownconverter steelmaking were also studied with oxygen sensor. It was found that the use of ferro-manganese for preliminary deoxidation at end-point has no evident effect, but that the oxygen contentis decreased about 50% by blowing in nitrogen. Oxygen sensor may also be used to judge and controlthe tendency towards swelling and skin blowhole formation in ingot teeming.

文章总结了作者1975年以来研制和使用钢液固体电解质浓差定氧电池的经验。通过对比试验,指出了提高其测成率和信号稳定性的一些关键。对测定结果的可靠性亦用多种方法进行过鉴定。用浓差定氧对电炉冶炼工艺进行研究得知:出钢终脱氧前熔池中的氧活度与钢材的氧化物夹杂评级密切有关,降低终脱氧前的钢中氧活度对提高钢材的洁净度有利。当采用铝预脱氧工艺时,电炉还原期可以大大缩短。用浓差电池定氧还研究了氧气底吹转炉冶炼过程中熔池含氧量的变化规律。判明了在吹炼终点使用锰铁预脱氧无明显效果。而鼓入氮气可以使钢中含氧量降低约50%。浓差定氧还可用于判断和控制钢锭上涨及皮下气泡的发生。

The essential globular inclusion in bearing steel smelted with white slag process in electric fur-nace are oxides of Al and Ca and small amount of Mg. This paper describes the forming mechanismof coarse globular inclusion through the agency of the redioisotope Ca~(45) as a "tracer". It is con-cluded that these inclusions are formed on the emulsified slag drip un-removed during tapping. Thispaper shows the reason of the analysis difference between the coarse globular inclusions in the prod-uct and slag during tapping. The relationship between the amount of inclusions come from mixedslag (Y) and time (X) follows the formula Y=De~(e/x). Some process factors such as: oxidation andeffervescence of steel, composition of reducing slag, desulfurizing efficiency and killed time etc.must be controlled so as to improve and stablize the quality of bearing steel. Utilization of headboxis beneficial to diminishing the amount of inclusions in ingot head.

电炉白渣法冶炼的轴承钢中的点状夹杂主要是Al和Ca的氧化物,此外还有少量Mg的氧化物。本文以放射性同位素Ca~(45)作为示踪元素研究了大颗粒点状夹杂的形成机构。结果表明,这些夹杂是由出钢过程未被排除的浮化渣滴生成的。本文指出了成品材的大粒点状夹杂和出钢时炉渣之间成分差别的原因,来自混渣造成的夹杂物的量(Y)和时间(X)之间的关系遵循下式:Y=de~(c/x)。一些工艺因素,诸如脱氧、钢的沸腾、还原渣成分、脱硫效率和镇静时间等必须很好控制,以改善和稳定轴承钢的质量。使用绝热帽有利于减少钢锭头部的夹杂。
