本文根据金属学和传热学原理,提出了一种铝质软管高温快速退火的新工艺,给出了与该工艺相适应的新型退火炉的设计方案。该炉采用传导和短距离辐射加热软管,发热元件同时兼作软管的承载件,因而将退火温度由480℃提高到550℃左右,退火时间由60s缩短到20s。现场使用表明,这种炉型具有明显的经济效益,节能达75%。 In this paper, according to the principles of metallography and heat transfer, a new rapid annealing process of aluminum hoses at high temperature is proposed, and a new annealing furnace design scheme is given. The furnace uses conductive and short-distance radiation heating hose, heating element also doubles as the hose carrier, so the annealing temperature increased from 480 ℃ to 550 ℃, annealing time reduced from 60s to 20s. Field use shows that this furnace has obvious economic benefits, saving up to 75%.
