火焰淬火时由于水嘴与火嘴的行进速度有时不一致,水压波动,火焰不稳定及模具形状的影响,淬火冷却水往往妨碍加热的正常进行,或者延长加热时间,或者飞溅的水使火焰熄灭。在加热时,一旦熄火,淬火间断,必然增加回火区,影响淬火质量。为了防止熄火,我们采取了加挡板的办法。在火嘴与水嘴间,加一块0.5～2mm厚的400×300mm铁板,距火嘴的加热中心
Flame quenching due to the sometimes inconsistent with the speed of faucet and nozzle speed, water pressure fluctuations, flame instability and the shape of the mold, quenching the cooling water often hindered the normal heating, or extend the heating time, or splashed water to extinguish the flame . In heating, once the flame, quenching intermittent, will inevitably increase the tempering zone, affecting the quenching quality. In order to prevent stalling, we have taken a baffle approach. Between the faucet and the faucet, add a piece of 0.5 ~ 2mm thick 400 × 300mm iron plate, away from the heating center of the faucet
