bell furnace

基本解释

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.
本发明不依靠冶炼时采用真空冶炼大幅度降低钢中的碳含量，而是采用罩式炉退火工艺，使钢中的碳在加热时充分固溶于钢中。

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.
在罩式炉内进行成品退火，快速升温到700-880℃范围内，保持8 -16小时，先缓慢冷却，再自然冷却至80℃以下时出炉。

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.
公司不锈钢冷轧项目采用这一技术后，实现了罩式炉生产的完全自动化，提高了生产的效率。
