美国空气制品与化学制品公司为气体研究院研究成功一种埋入式燃烧法,并已在这种废钢熔炼法的样机上完成了初步试验。据预测,这种方法将成功地取代现今各种电弧炉,甚至比新设计的一些电炉操作效果更佳。该系统设计的核心在于使用埋入式和顶部煤气/氧气烧嘴,使加入的废钢形成熔池。在出钢前切断煤气/氧气流,改喷惰性气体,以避免烧嘴堵塞。为下一次装料需在炉内留部分钢水。还要注意一些问题,例如控制钢水氧化、设计和研制一种合适的烧嘴及钢水喷溅炉壁
American Air Products and Chemicals Company, a successful in-built combustion method for the Gas Research Institute, has completed preliminary tests on a prototype of this scrap melting process. It is predicted that this method will successfully replace all kinds of current electric arc furnaces and even operate better than some newly designed electric furnaces. At the heart of this system design is the use of in-line and top gas / oxygen burners to make the added scrap form a weld pool. Shut off the gas / oxygen flow before tapping and change the inert gas to avoid clogging the burner. For the next charge to stay in the furnace part of the molten steel. Also pay attention to some issues, such as control of molten steel, design and development of a suitable burner and molten steel splashing furnace wall
