一、前言辐射管作为一种合理的加热元件已在可控气氛炉等热处理设备上普遍使用。据报道,日本现在热处理主要设备都采用辐射管加热技术,尤以连续渗碳炉和万能炉为多。辐射管加热具有以下特点:①生产中可以更换而不影响生产;③功率分布更加合理;③有利于炉内气氛的流动;
I. Introduction Radiation tube as a reasonable heating element has been widely used in heat treatment equipment such as controlled atmosphere furnace. It is reported that Japan now heat treatment of major equipment uses radiant tube heating technology, especially in continuous carburizing furnace and multi-purpose furnace. Radiation tube heating has the following characteristics: ① production can be changed without affecting the production; ③ power distribution more reasonable; ③ is conducive to the flow of furnace atmosphere;
