脱碳退火热处理线(DCL):冷轧带钢经过辐射管炉加热到退火温度,缓慢冷却到600°℃,冷却速度控制在10°℃/Sec,再快速冷却100°℃以下。炉内气氛为氢气(最高比例达到75%)和氮气,同时可以对保护气氛加湿或通入适当的氨气,可用于对带钢脱碳或渗氮功能。退火后,钢带表面会被涂上 MgO涂层,最后进行涂层干燥、冷却。
Decarbonizing Annealing line (DCL): Cold rolled strip is heated to annealingtemperature in a radiant tube furnace(RTF) and cooled slowly to 600cwith controlled cooling speed at 10°C/Sec, then cooled down below100°℃ rapidly . The atmosphere gas in the furnace is hydrogen (up to 75%)and nitrogen, a proper amount of ammonia gas or moisture is injected inorder to decarburizing or nitriding of strip. After annealing the surface of steel strip is coated with MgO and finally the coating is dried and cooled to ambient temperature.

最终热拉伸平整线(FCL):绝缘涂层后带钢进入明火加热，带钢加热到700°℃左右,进入辐射管加热到工艺温度,保温;缓慢冷却到~600°℃,冷却速度控制在10°℃/Sec,再快速冷却300°℃以下,该段炉内采用N2+H2保护气氛;出炉后采用空气喷射冷却方式冷却到~80°℃。
Final Hot Stretching and Flatting Line (FCL): After the insulation coating,strip is heated to 700°C by open fire, then proceeds into the RTF and continue heating to the process temperature, holding for a period of time, then cooled slowly to 600°C with controlled cooling speed at 10°C/Sec, after that cooled down below 300°C rapidly，hydrogen and nitrogen are adapted as atmosphere gas in RTF; finally strip is cooled to 80°℃ by air jet cooling(AJC) at the out of the furnace.

无取向硅钢退火线(ACL):冷轧钢带通过辐射管炉或者明火无氧化加热炉加热到退火温度,均热一定时间,炉内气氛为氢气和氮气,或加入湿气氛来控制脱碳能力。然后开始时缓慢冷却，温度降到600°C后快速冷却至80°℃。退火后,钢带表面会涂上绝缘涂层,并进行涂层干燥、烧结。

Non-oriented silicon steel annealing line (ACL): Cold rolled strip is heated to annealing temperature in a RTF or in an open fire non-oxidationfurnace, holding for a period of time, the atmosphere gas in the furnaceis hydrogen and nitrogen and humidifying atmosphere is also used tocontrol the decarbonizing.After that strip is cooled slowly to 600°cthen cooled rapidly below 80°℃.After annealing the surface of steel strip is coated with insulating coating, and the coating is dried and sintered in the end.
