锻造温度，锻造温度控制在820～850℃，当然，如果内在冶金质量不错，锻坯表面质量不错的话，也可在780℃左右轻锻、修光、精整等等。
碳钢正确的锻造温度范围应不包括工业纯铁。
So the correct carbon steel forging temperature range does not include industrial pure iron.
重要的是较低的锻造温度和热处理固溶温度比较高的好得多。
It is important to control the forging temperature and solution treatment temperature lower rather than higher.
