近来,冷轧带钢生产技术的发展主要有以下几个方面:(1)增加钢卷质(重)量:增加钢卷质量是提高设备生产能力的有效方法,因为冷轧带钢是以钢卷方式生产的,每一个钢卷在送到机组内轧制或处理前,都必须经过拆捆、开卷、穿带,然后加速到正常速度工作,在每一卷终了时又需要有减速、剪切、卷取及卸卷的过程,占用较多的生产时间。钢卷质量增大后,可相应地增加作业的时间,而且由于每卷带钢长度的增加,带钢在稳定速度下轧制的时间也相应增加,机组的速度才能真正
Recently, the development of cold-rolled strip production technology mainly in the following areas: (1) increase the volume of steel (heavy) volume: increase the quality of the coil is an effective way to improve equipment production capacity, because the cold-rolled strip steel is steel Volume production, each coil sent to the unit within the rolling or processing, must be demolished bundles, unwinding, wearing, and then accelerated to normal speed work, at the end of each roll also need to slow down, cut Cutting, coiling and unloading process, take up more production time. When the quality of the coil increases, the operating time can be correspondingly increased, and as the strip length per roll increases, the rolling time of the strip at the steady speed increases correspondingly, and the speed of the unit can be real
