So the correct carbon steel forging temperature range does not include industrialpureiron.
碳钢正确的锻造温度范围应不包括工业纯铁。
2
The qualified industrialpureiron whose carbon content is below 0.025% has been made in laboratory.
在实验室中制备出含碳量低于0.025%合格的工业纯铁。
3
A new way for making industrialpureiron is put forward. It includes three steps-hot metal granulation, solid state decarbonization and electric furnace melting down.
