喷雾冷却;喷雾降温
This paper introduces the principle, construction and application of a mist cooling device for H-beam rolling. The mist cooling device is developed and manufactured by the State Key Lab of Rolling Technology and Automation ( Northeastern University) and has applied at Laiwu Steel.
从原理、结构以及现场应用效果方面,介绍由东北大学轧制技术及连轧自动化国家重点实验室自主设计和制造的H型钢气雾冷却装置。
By means of the heat treatment process such as mist cooling after forged+ normalizing mist cooling+ spheroidal annealing, in this case, the qualification rate of carbon network of the bearing steel forging shall be improved from 66% to ( 93.4%).
通过采用锻后雾冷+正火雾冷+球化退火的热处理工艺,将轴承钢锻件网状碳化物的合格率从66%提高至93.4%。
