随着机械零件制造工艺水平的提高,少无切屑工艺的广泛采用,在精密模锻、热挤压和精辊等工序前,坯料必须采用少无氧化加热。根据叶片精辊精锻工艺的要求,由华中工学院与东方汽轮机厂合作,共同研制成功了一台新型的转底式天然气少氧化加热 With the improvement of the manufacturing technology of mechanical parts and the widespread adoption of less chip-less process, the blanks must be less non-oxidized and heated before precision die forging, hot extrusion and finishing rolls. According to the requirements of the precision forging process of the blade fine roller, Huazhong Institute of Technology cooperated with Dongfang Steam Turbine Plant to jointly develop a new type of rotary oxidation-less natural gas heating
