众所周知,由于步进式加热炉有着推钢式加热炉无法比拟的优点,诸如,不拱钢,不粘钢,氧化烧损小,脱碳少,加热时间短,加热操作灵活,易干和轧制节奏相匹配,加热过程中不划伤,炉子长度不受限制(从理论上讲)自动化程度高,易于采用计算机控制等优点.因此尽管步进炉一次投资费用高,但是,自从1967年4月由美国米德兰公司设计的二面供热的步进梁式炉首先在美国格兰那特城钢铁公司问世以来,接着同年5月由日本中外炉公司为名古屋钢铁厂设计的世界上第二座步进梁式炉又相继投产,以后步进式加热炉在世界上获得了长足的发展.尤其近10多年来,随着轧钢技术向着连续化、大型化、自动化、多品种、高精度的发展,步进式加热炉为适应工艺的要求,也朝着大型化、多功能、优
As we all know, because the stepping furnace has a push-type furnace unparalleled advantages, such as not arch steel, non-stick steel, small oxidation loss, less decarburization, heating time is short, flexible heating operation, easy to dry and rolling The pace of the match, the heating process is not scratched, the furnace length is unlimited (in theory) a high degree of automation, easy to use computer control, etc. Therefore, despite the stepping furnace investment costs are high, but since 1967 4 Month By the United States Midland designed two-sided heating of the walking beam furnace First in the United States Grant Lancaster Iron and Steel Company since its inception in May the same year by Japan and foreign furnace company for the Nagoya Steel Works designed the world’s second Walking beam furnace have been put into operation, after the step-by-step furnace in the world has made considerable development.Especially in the past 10 years, as the rolling technology toward continuous, large-scale, automation, variety, high-precision development step Into the furnace to meet the requirements of technology, but also toward large-scale, multi-function, excellent
