前言国内的喷射冶金工艺目前正在迅速发展,但作为该项工艺技术的核心设备——喷粉罐,在结构上能满足喷吹过程中实现调节供粉速度方面仍存在不少困难。我院在总结唐山钢厂氧气底吹转炉喷粉和首钢、济南二钢氧气底吹转炉喷粉系统的基础上,又在我院实验室设计制造了半工业规模的“可调喉口式流态化喷粉罐”。经过将近一年的实验室试验, Preface Domestic jet metallurgical process is rapidly developing, but as the core technology of the process equipment - spray cans, in the structure to meet the injection process to achieve regulation of powder feeding speed there are still many difficulties. On the basis of summing up the oxygen bottom blowing converter dusting of Tangshan Iron and Steel Plant and the powder blowing system of oxygen bottom blowing converter of Jinan Iron and Steel Co., Ltd., our hospital also designed and manufactured semi-industrial scale “adjustable throat flow State of the duster. ” After nearly a year of laboratory tests,
