增压器涡轮的整铸工艺,早在1966—1969年由天津机车车辆机械工厂、上海新中动力机厂、南字836部队、戚墅堰机车车辆工艺研究所组成的研究小组,对50~#增压器涡轮进行了研制工作,并于1970年1月经过了有关部门鉴定。但是80系列增压器涡轮的工作条件比50~#增压器涡轮更为恶劣、条件更为苟刻。增压器涡轮材料采用的是K_(13)奥氏体铁基耐热合金。因此,给熔模铸造工艺和加工工艺增加了一定的
Turbocharger turbine casting process, as early as 1966-1969 by the Tianjin rolling stock machinery factory, Shanghai Xinzhong Power Plant, the Southern word 836 units, Qishuyan rolling stock Technology Research Institute composed of research groups, 50 ~ # booster Turbine turbine has been developed, and in January 1970 after the relevant departments appraisal. However, the working conditions of the 80 series turbocharger turbines are even worse than those of the turbochargers 50 ~ #, and the conditions are even worse. Turbocharger turbine material is used K_ (13) austenitic iron-based heat-resistant alloys. Therefore, to the investment casting process and processing technology increased a certain amount
