锻件生产模锻化的新捷径用铸钢堆焊法造大型锻模第一汽车制造厂用铸钢堆焊的方法制造成功十吨锻锤用的锻模。用这种锻模生产锻件,质量和用合金钢锻模生产的完全一样。用锻模生产锻件的方法来代替不用锻模(自由锻)生产锻件的方法,是我国机械工业技术革命的一项重要措施。模锻比自由锻生产的产品质量高,又可以节约二
Forging a new shortcut for the production of Forging with cast steel surfacing welding large forging die First Automobile Works with steel surfacing welding method for the success of ten tons forging hammer forging die. Forging is produced from this forging die, the quality of which is exactly the same as that produced from an alloy steel forging die. The method of producing forgings by using forging dies instead of using forging dies (free forging) is an important measure for the technological revolution of China’s machinery industry. Forging than the free forging production of high quality products, but also can save two
