近年来随着钢铁、机械、造船、石油化工等工业的迅速发展,国内外的气割机械化和自动化有了很大的提高,且在采用液化石油气取代常用的乙炔气也有所进展。这种先进的工艺方法不仅可提高切割速度和切口表面光洁度,而且还可降低成本,是:有发展前途的。本文将重点介绍氧-液化石油气快速切割工具的设计和制造(关 In recent years, with the rapid development of industries such as iron and steel, machinery, shipbuilding and petrochemicals, the mechanization and automation of gas cutting at home and abroad have been greatly improved. In addition, liquefied petroleum gas has been used to replace common acetylene gas. This advanced process not only improves cutting speed and cut surface finish, but it also reduces costs and is: promising. This article will focus on oxygen - liquefied petroleum gas rapid cutting tool design and manufacture (off
