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.
本發明不依靠冶鍊時採用真空冶鍊大幅度降低鋼中的碳含量，而是採用罩式爐退火工藝，使鋼中的碳在加熱時充分固溶於鋼中。

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.
在罩式爐內進行成品退火，快速陞溫到700-880℃範圍內，保持8 -16小時，先緩慢冷卻，再自然冷卻至80℃以下時出爐。

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.
公司不鏽鋼冷軋項目採用這一技術後，實現了罩式爐生産的完全自動化，提高了生産的傚率。
