用于热轧带卷快速冷却的强制水冷法和空冷法获得了最广泛的应用。带卷采用水冷可以缩短冷却时间(在日本钢管公司2400热轧机上36吨以下带卷的水冷时间比空冷时间短2/3),并且可以缩短酸洗时间(20吨以下带卷使用10%的盐酸溶液可缩短1/2～2/3的酸洗时间)。36吨带卷从550℃冷到50℃的强
Forced cooling of hot-rolled coils forced cooling and air-cooling method has been the most widely used. Water cooling of the coil reduces the cooling time (2/3 of the 36-ton coil on the Nippon Steel Corporation 2400 hot-rolling mill) and shortens the pickling time (coils up to 20 tons use 10% Hydrochloric acid solution can be shortened 1/2 ~ 2/3 pickling time). 36 tons of coil from 550 ℃ cold to 50 ℃ strong
