bell furnace

基本解釋

The invention adopts annealing technology of the bell furnace instead of vacuum smelting greatly reducing the C content to dissolves C into the steel during heating.
本發(fā)明不依靠冶煉時(shí)采用真空冶煉大幅度降低鋼中的碳含量，而是采用罩式爐退火工藝，使鋼中的碳在加熱時(shí)充分固溶于鋼中。

To complete final annealing in the bell furnace, heat the temperature to 700-880 C degree quickly and keep for 8-16h, cooling slowly and naturally below 80 C degree to convert.
在罩式爐內(nèi)進(jìn)行成品退火，快速升溫到700-880℃范圍內(nèi)，保持8 -16小時(shí)，先緩慢冷卻，再自然冷卻至80℃以下時(shí)出爐。

After this technique was adopted by stainless steel cold rolling project of company, the full automation is realized and the efficiency is improved in production of bell furnace.
公司不銹鋼冷軋項(xiàng)目采用這一技術(shù)后，實(shí)現(xiàn)了罩式爐生產(chǎn)的完全自動(dòng)化，提高了生產(chǎn)的效率。
