摘要
通过试制18Mn12Cr18Ni2N钢船用尾轴,确定了该产品的制造工艺:电炉冶炼+电渣重熔,始锻温度1 120℃,终锻温度950℃,初始压下量小于30 mm。
By the trail production of 18Mn12Cr18Ni2N Steel tail-shaft for ship, the manufacture process of this product has been defined. That is electric-furnace smelting ＋ electro-slag remelting, 1 120 ℃ of the beginning forging temperature, 950℃ of the end forging temperature and less than 30 mm of the begin screwdown.
