1.内容简介转炉炼钢在吹炼过程中要产生大量含CO的烟气。为此,冶金部自动化研究所、建研总院、上海冶金设计院等单位,在消化吸收国外引进技术与结合国情之后,在上钢一厂、三厂等单位进行了回收转炉煤气。该系统除气体净化与分析外,已全部立足国内。煤气回收的主要内容包括:可调喉口—RD文氏管阀及炉口微差压控制系统;液压伺服机构;转炉煤气三通切换阀;转炉煤气文氏
1. Introduction BOF in the blowing process to produce a large number of CO-containing flue gas. To this end, the Ministry of Metallurgical Institute of Automation, Research Institute, Shanghai Metallurgical Design Institute and other units in the digestion and absorption of imported technology and the combination of national conditions, the first steel plant, three plants and other units for the recovery of converter gas. The system in addition to gas purification and analysis, have all based on domestic. The main contents of gas recovery include: adjustable throat -RD venturi valve and mouth differential pressure control system; hydraulic servo; Converter gas three-way switch valve;
