压力容器用钢氧化物冶金技术研究

Researches on Oxide Metallurgical Technology of Steel Using in Pressure Vessel

随着我国工业化进程的飞速发展,压力容器在工业企业中的应用越来越广泛,对于压力容器的质量、性能也提出了更高的要求。不仅要求压力容器要具备高强度和高韧性,还要具备良好的焊接性。目前,压力容器焊接过程中,经常会出现晶体粗化、焊接裂纹等方面的问题,对压力容器的产品质量造成了严重的影响。氧化物冶金技术是现阶段压力容器制造过程中一种比较常见的技术手段,对于抑制粗化、减少裂纹都有很大的帮助。

With the development of industry, in our country,the using of pressure vessel become more and more wide in industrial enterprise,which put forward higher request to the quality and performance of pressure vessel,not only demand the pressure vessel has high strength andtenacity,but also better weldability.At present,during the process of vessel soldering,the problem of crystal coarsening and the welding crackoccur frequently,which bring serious influence to the quality of pressure vessel.Oxide metallurgical technology is the usual technology in pres-sure vessel producing, which do a lot of help in coarsening control and crack reduce.
