前言高炉铁水炉外脱硫因长年连续生产,必须要求可靠,否则会因硫高废铁而造成经济损失。喷枪是喷射法脱硫必不可少的消耗器材,要求一定寿命并保证及时供应。我国铁水脱硫起步晚,至今尚不普及,对喷枪的研究也少,大部分脱硫(或脱硅、脱磷)试验,均用袖 Preface Blast furnace hot metal outside the desulfurization continuous production for many years, we must request reliable, otherwise it will be caused by high sulfur scrap iron and economic losses. Spray gun spray desulfurization is an essential consumer equipment, require a certain life expectancy and to ensure timely supply. China’s hot metal desulfurization started late, so far not yet widespread, the research on the gun is also less, most of the desulfurization (or desiliconization, dephosphorization) test, both with sleeve
