较长时期来,国内滑动水口钢包浇注不锈钢的引流技术未得到良好解决,当采用“电弧炉+VOD精炼+液渣保护浇注”的不锈钢冶炼工艺路线时,完善开浇引流问题显得格外重要,因此曾被冶金部列为1984年炉外精炼攻关项目之一。国内有些钢厂为了正常开浇,不得不将精炼后的不锈钢再倒入陶塞杆钢包去浇注,这无疑会影响钢液温度和破坏精炼效果。上海第三钢铁厂从1983年2月起,经过2—3年的努力,反复试验,开发了一种适
Over a long period of time, the drainage technology of domestic sliding ladle ladle for stainless steel casting has not been well solved. When adopting the stainless steel smelting process route of “electric arc furnace + VOD refining + liquid slag protection pouring”, it is especially important to improve pouring drainage. Metallurgical department was listed as 1984 one of the furnace refining project. Some domestic steel mills in order to open normal, had to pour the refined stainless steel into the trowel ladle to pour, which will undoubtedly affect the molten steel temperature and destroy the refining effect. Shanghai Third Steel Works from February 1983 onwards, after 2-3 years of hard work, repeated tests and developed a suitable
