Abstract To solve the problem of high venting explosions rate，low recovery of gas and bad de-dusting effect while the dry de-dusting technology was applied on 200 t semi-steel steelmaking converter of Xichang Steel-Vanadium Steel Plant of Pang Gang Group，the theory of venting explosions and the difficulty while applying on semi-steel steelmaking converter were analyzed based on the practice of production. Some measurements，such as optimizing rotation speed of wind turbine，oxygen blowing system，choosing reasonable charging process and position of oxygen lance，were proposed. The effects after industrial application indicated that by optimizing the technological parameter of semi-steel steelmaking，the venting explosions rate decreased from 7.60% to 0.08%，the LDG recovery ratio increased from 54.6 m3/t to 123.6 m3/t，and the fly ash recovery ratio increased as well. In addition，the smelting cycle and the oxygen consumption were reduced by 4 min and 2.4 m3/t，respectively，and the effect of dust removal was better，which ensured the normal blowing of converter and greatly reduced the energy consumption.
