第一汽車制造厂用鑄鋼堆焊的方法制造成功十吨鍛錘用的鍛模。用这种鍛模生产5万瓩汽輪机叶片,質量和用合金鋼鍛模生产的完全一样。在使用寿命方面,10吨錘原用的高級合金鋼鍛模鍛打5万瓩汽輪机叶片定额为3000片,現在用鑄鋼堆焊鍛模已打1700片,估計还可以再打1700片左右;在节約方面,制造成本减少了75％,节約合金元素铬、钼95％左右;焊縫質量經过鉴定完全合乎技术要求。
First Automobile Manufacturing Plant with a method of welding steel to create a successful ten-ton hammer forging die. With this die for the production of 50,000 瓩 turbine blades, the quality and production of alloy steel forging exactly the same. In terms of service life, 10 tons of original high alloy steel forging die forging 50,000 瓩 turbine blade quota of 3000, and now cast steel forging die has hit 1700, it is estimated that you can play about 1700 ; In terms of saving, manufacturing costs reduced by 75%, saving alloying elements chromium, molybdenum about 95%; weld quality is fully qualified to meet the technical requirements.
