当没有高中频设备而需进行齿轮表面淬火时,可用中、低压乙炔发生器,采用火焰淬火。当不具备这种乙炔发生器时,我们采用几个浮桶式乙炔罐串联(见图),并通过配重的方法解决了齿轮表面淬火问题。该法是将2～3个乙炔罐串联为一组,用粗皮管(3/4英寸钢管亦可) When there is no high-frequency equipment required gear surface hardening, the available low-voltage acetylene generator, flame quenching. When this type of acetylene generator is not available, we use several float barrel acetylene cascades in series (see photo) and solve the problem of gear surface hardening by counterweighting. The law is to 2 to 3 acetylene cans in series as a group, with a rough skin (3/4 inch steel pipe can be)
