该定向结晶浇铸炉已于1980年10月初在上海电炉厂完成总装和冷态调试工作。目前正准备装箱,运往西北工业大学,以便最后完成热态调试。今后将供西北工业大学作科研和教育使用。 该炉由上海电炉厂和三机部六二一所联合设计,并由上海电炉厂加工制造。 该炉用于研制和生产高温合金的真空重熔、真空浇铸定向结晶叶片(涡轮叶片和导向叶片)。 炉子参数:坩埚最大容量15公斤。熔化温度1700℃,壳模加热温度1700℃。极限真空5×10~(-4)毫米汞柱,漏气率
The directional crystal casting furnace has been completed in early October 1980 in Shanghai Electric Furnace Factory assembly and cold start debugging. Is currently preparing packing, shipped to Northwestern Polytechnical University, so that the final completion of thermal debugging. Northwestern University for future research and education for future use. The furnace by the Shanghai Electric Furnace Factory and the Ministry of Machinery June 21 jointly designed and manufactured by the Shanghai Electric Furnace Factory. The furnace for the development and production of high-temperature alloy vacuum remelting, vacuum casting directional crystal blades (turbine blades and guide vanes). Stove parameters: crucible maximum capacity of 15 kg. Melting temperature 1700 ℃, shell mold heating temperature 1700 ℃. Extreme vacuum 5 × 10 ~ (-4) mmHg, leak rate
