氧—乙炔焰表面淬火是一种传统的淬火工艺。本文中,作者提供了一些新的数据,包括钢在表面加热时的温度测量以及氧和乙炔气混合燃烧时中性焰的混合比,可供参考。 Oxygen - acetylene flame quenching is a traditional quenching process. In this paper, the authors provide some new data, including the temperature measurement of steel when heated on the surface, and the mixing ratio of neutral flame when mixing oxygen and acetylene gas for reference.
