在带材连续作业精整机组中,张力对控制带材跑偏有较大作用,如果张力过小,容易出现带材跑偏现象,而且带卷也不能卷紧卷齐;张力过大,则会使开卷机和卷取机,以及机组中的其它张力装置的传动设备过大,功率过高,从而增加设备投资,甚至还会拉断带材而影响机组正常工作。因此恰当选择机组各部分的张力是精整机组设计中很重 In the continuous operation of the strip finishing unit, the tension on the control strip deviation has a greater role, if the tension is too small, prone to strip deviation phenomenon, but the coil can not be rolled tight Qi Qi; tension is too large, It will make uncoiler and coiler, as well as other tension devices in the unit transmission equipment is too large, high power, thereby increasing equipment investment, and even pull the strip will affect the normal operation of the unit. Therefore, the appropriate choice of the tension of the various parts of the unit is finishing unit design is very heavy
