从钢锭的加热、锻造、锻后处理三方面提出控制大型锻件质量的方案。
Quality control of large pieces of forging lies in the manipulating of heating, forging and post-forging treatment of steel ingots.
锻造钢锭多采用热锭加热，其特点是在恒温炉中一段加热和在变温炉中两段或三段加热方式。
Hot ingots are often heated in forging furnaces, the feature of which is one-stage type in a constant temperature furnace and two-or three stage type in a temperature-variable furnace.
对发生热脆锻裂的钢锭的加热规范进行了统计分析，发现现行的热锭加热规范有可能造成钢锭热脆。
After the statistical analysis of the heating specification on the hot-short ingot, we found that the heating specification of hot ingot would probably cause the ingot hot short.
