一、电热罩式退火炉的结构及工作情况电热罩式炉是用作普通薄板及低矽钢片退火的。功率为250瓩,装炉量为18至20吨,最高炉温为850℃,退火温度为600℃～700℃。从工作条件来看,是属于周期作业炉。二台一罩为一组,炉台周期约48小时左右,即升温18至20小时,保温4至6小时,保温结束后吊外罩,随炉台冷却16至18小时出炉, First, the structure and work of the electric bell annealing furnace Electric bell furnace is used as ordinary sheet and low silicon steel annealing. The power is 250 瓩, the loading capacity is 18 to 20 tons, the highest furnace temperature is 850 ℃ and the annealing temperature is 600 ℃ ~ 700 ℃. From the working conditions, it is a cycle furnace. A set of two sets of a stove, stove cycle about 48 hours or so, that is, heating 18 to 20 hours, holding 4 to 6 hours after the end of the suspension hanging cover, with the stove cooling 16 to 18 hours baked,
