美国有关冶金学家认为,蒸汽处理有助于延长部件寿命,防止腐蚀,弥合气孔,改善表面质量。该种处理技术常被忽视,有必要重新提请人们使用。在处理黑色金属时,先用空气将炉子加热至370℃,保温30分钟,注入蒸汽置换炉膛中的空气。然后,将工件加热至处理温度并保温一定时间,蒸汽连续流动通过炉膛。处理完毕后,工件取出空冷。
The United States, metallurgists believe that steam treatment can help extend component life, prevent corrosion, to close the pores, improve the surface quality. Such treatment techniques are often overlooked and need to be re-introduced to people. In the treatment of ferrous metals, the furnace is first heated to 370 ° C with air and incubated for 30 minutes to inject steam to replace the air in the furnace. Then, the workpiece is heated to the processing temperature and incubated for a certain period of time, and the steam flows continuously through the hearth. After processing, the workpiece removed air-cooled.
