罩退生产灵活,产量低,造价低。连退不适合超薄板,产量大,造价高。工艺不同,罩退590-710度,周期长。连退600-700度,30S-180S.
连退、罩退都是三个过程,即加热、保温、冷却。连退加热均匀,根据板宽、板厚、材质、速度制定工艺,罩退是根据板宽、板厚、材质、炉况制定工艺。

    如果是选项的话,这二种类型各有优势,还有考虑你工件、产量、工艺等要求来考虑。

  连续退火炉是连续炉,产量高,劳动强度低。特别适合简单热处理工艺,大批量小型工件的退火热处理,相对来说炉子成本高。

  罩式退火炉属于周期性炉,具有保温性能好、节能、气氛可控、多种工艺可用、炉子成本相对连续炉低。特别适用于带材、卷材、不锈钢、铜材等热处理。
