中温电阻炉一般指700℃～1250℃的电炉。在这个温度范围内,主要靠辐射传热。温度的上限决定于金属加热元件在氧化性气氛(空气)中所能使用的温度。温度再高时,就必须采用非金属加热元件或者采用只能在真空或保护气氛中工作的金属加热元件。所以高温电炉的结构同中温电炉的结构有显著的不同。 中温电阻炉主要用于一般钢制品的正火、退火和淬火。中温电阻炉的种类非常多。目前
Medium temperature resistance furnace generally refers to the 700 ℃ ~ 1250 ℃ electric furnace. Within this temperature range, heat is mainly transmitted by radiation. The upper limit of temperature depends on the temperature at which the metal heating element can be used in an oxidizing atmosphere (air). When the temperature is high, non-metallic heating elements must be used or metal heating elements that work only in a vacuum or in a protective atmosphere. Therefore, the structure of high temperature electric furnace temperature furnace structure with significant differences. Medium temperature resistance furnace is mainly used for normal steel products of normalizing, annealing and quenching. Medium temperature resistance furnace type is very large. Currently
