在钢铁元帅和铜铝副帅升帐后,冶金焦已感供不应求,是从事冶金工作的生产人员和科学研究人员当前的一个重要课题。我厂职工响应党中央开展增产节约,猛攻技术关的号召,于今年3月份起,对铜鼓风炉使用土焦代替冶金焦(一开始便是100％的代用)已经获得了成功。(一)土焦与冶金焦的物理性质及化学成份的比较土焦火焰短、着火点低、强度差、比重大、热稳定性差、燃烧后灰份高、挥发物高、含固定炭低发热值小,是地方采取土办法所生产的成品。1.工业分析比较:
Metallurgical coke has been in short supply after the marshal of steel and the copper-aluminum sub-Shuai account, which is an important issue currently facing the production personnel and scientific researchers engaged in metallurgy work. In response to the Central Party Committee’s call for increasing production and saving energy and storming the technology, our factory workers have succeeded in using the pyrometallurgy coke instead of the metallurgical coke for the copper blast furnace since the start of this year (at the outset, 100% substitution). (A) Comparison of the physical properties and chemical composition of coke and metallurgical coke Coke has a short flame, low ignition point, poor strength, large proportion, poor thermal stability, high ash content after combustion, high volatility, low calorific value Small, is the place to adopt the local production of finished products. 1 industrial analysis and comparison:
