现代石油、化学、发电工业的发展,出现了结构大型化的趋势,如压力容器、反应器和高压贮槽等,更是向高参数、大容量的方向发展。对高压容器的制造,采用热套工艺,在我国发展很快。我厂曾对14MnMoNbB高强钢筒体的热卷、热校,以及调质处理后套合面不经机械加工的套合工艺,作了生产性验证,表明这种高强度钢热套容器的制造工艺是可行的;性能 With the development of modern petroleum, chemical and power generation industries, large-scale structural trends have emerged. For example, pressure vessels, reactors and high-pressure storage tanks are developing more toward higher parameters and larger capacity. The manufacture of high pressure vessels, the use of thermosetting process, developed rapidly in our country. Our factory has 14MnMoNbB high-strength steel cylinder of the hot roll, hot school, and quenched and tempered after the sleeve without mechanical processing sets of technology, made a productive verification, indicating that the high-strength steel thermowell manufacturing Process is feasible; performance
