80年代后期,抚顺钢厂承担了为某工程的大型汽轮机叶片用TC4钛合金方棒研究课题,要确保按时完成课题要求,考虑到在蒸汽锤上锻造的弱点,进而采用了锻压技术. 合金锭用1t真空白耗电弧炉,经两次熔炼熔铸成中380mm。铸锭,并车光。锭坯在重油炉中加热,开坯加热温度在1010～1150℃范围内,采用2000t快锻机制坯,先把铸锭直接镦粗,再采用带钳把平镦,后又反复镦
In the late 1980s, Fushun Steel undertook a research project on the square rods of TC4 titanium alloy for large steam turbine blades of a certain project. It was necessary to ensure the completion of the project requirements on time and to take into account the weaknesses in the forging of the steam hammer and further the forging technology. With 1t vacuum consumption of electric arc furnace, after two melting cast into a 380mm. Ingot, and car light. Billets are heated in a heavy oil furnace, the billet heating temperature in the range of 1010 ~ 1150 ℃, the use of 2000t fast forging billet, the first direct upsetting ingot, and then use the pliers flat upsetting, and then repeatedly upsetting
