冶金焦的来源是比较缺乏的,价格昂贵,对于生产方面影响很大。因此,寻求冶金焦的代用品的试验,是从事冶金工作的生产人员和科学研究人员的一个重要课题。本刊在去年第8期上,曾报导过关于铜鼓风爐,使用天然焦代替冶金焦的筒单试验情况。第一冶炼厂的职工们响应党中央开展增产节约的号召,自1956年9月份开始,到今年1月份止,对铅鼓风爐使用天然焦,先后进行了3次试验。试验结果证明:用天然焦代替冶金焦到25％,全年可节省冶金焦1,800吨,使生产成本大大降低(天然焦与冶金焦的每吨单价相差10倍)。此外,使用天然焦对于降低渣含铅、改进技术操作上,也起着一定作用(该厂去年9月份渣含铅平均为1.511％今年1月则下降平均为1.165％)。本刊发表此文,希望能引起各方面的重视,继续从理论上和生产上加以研究,以期获得全面总结,达到普遍推广的要求。
The source of metallurgical coke is relatively scarce, expensive, for the production of a great impact. Therefore, the test of seeking substitutes for metallurgical coke is an important issue for producers and researchers engaged in metallurgy work. In the last issue of the 8th issue, we reported on a single trial of copper blast furnaces using natural coke instead of metallurgical coke. In response to the Party Central Committee’s call for increased production and saving, the workers of No. 1 Smelter conducted three experiments successively using natural coke for lead blast furnaces since September 1956 and ending January of this year. The test results show that replacing 25% with natural coke instead of metallurgical coke can save 1,800 tons of metallurgical coke throughout the year, greatly reducing the production cost (the difference between natural coke and metallurgical coke is 10 times of the unit price per ton). In addition, the use of natural coke also plays a role in reducing the lead content in the slag and improving the technical operation. (The average slag content of the plant in September last year was 1.511%, while the average drop in January this year was 1.165%). This article published this article, hoping to arouse the attention of all parties, continue to study in theory and production, in order to obtain a comprehensive summary, to achieve universal promotion requirements.
