Eight plants of Hunan Shuikoushan Nonferrous Metals Company adhered to the road of scientific and technological innovation. After more than one year of trial operation, the technical indicators of the lead content in the blast furnace slag were reduced to below 3.5%, and the technical indicators of the bottom lead blast furnace lead rate reached over 45%. The creation of the domestic first-class technical level marks the significant improvement and development of the production process of the Shuikoushan Smelting Base.
Due to the strong compactness of the high lead slag smelted by the blast furnace, the furnace knot of the blast furnace hearth is easy to form. The plant aimed at this technical problem, formulate a reasonable ingredients program, to avoid the frequent occurrence of blast furnace hearth furnace knot, and achieved a major breakthrough in key technical indicators. Since March, the lead content of the blast furnace slag has been steadily dropped below 3.5%. The lead blasting rate in the bottom furnace has reached over 45%, and the lead grade of the high lead slag has dropped below 40%, both reaching the leading level in the domestic industry.
The plant achieved a major breakthrough in the key technical indicators in the technical field of oxygen bleed blast furnace blast furnace reduction lead smelting process, accumulated rich experience for the rapid development of China's lead smelting industry, so that "Haikoushan lead smelting method" production process more To become more sophisticated, the smelting economic and technical indicators have become more mature.
