一、前言五机架冷轧后的钢卷必需经过退火方能消除加工硬化,故罩式退火炉是冷轧厂的一个重要生产环节,其生产能力关系到整个冷轧厂的生产能力的发挥,关系到冷轧厂的产量和利润的提高。为了搞清楚不同品种、不同宽度规格产品的吨占炉座时间,妥善地安排产品结构,以便充分地发挥罩式退火炉的能力,我们根据冷轧厂84年和85年的部份生 I. INTRODUCTION The steel coil after cold rolling of five stands must be annealed to eliminate work hardening. Therefore, the hood annealing furnace is an important production link of the cold rolling mill. Its production capacity has a bearing on the production capacity of the entire cold rolling mill. , Related to cold rolling mill production and profits increase. In order to clarify the different varieties, different width specifications of the tons of stoves occupy the time, properly arrange the product structure, in order to fully develop the capacity of the bell-type annealing furnace, according to our cold-rolled plant 84 and 85 years of some students
