三辊卷板机能力的大小是由其能卷制钢板的最大厚度和宽度限制的。例如19×2000三辊卷板机只能加工2米宽19毫米厚的钢板。如果超过这个限度就被视为超过了设备的设计能力,而这种超负荷操作是不允许的,也不安全。但是在实际生产中,常常会遇到欲加工的钢板厚度超过卷板机所允许的 The capacity of a three-roll coiler is limited by its maximum thickness and width that can be rolled. For example, 19 × 2000 three-roll coiler can only process 2 meters wide and 19 mm thick steel. Exceeding this limit is considered to exceed the design capability of the equipment, and such overloading operations are not permitted nor safe. However, in actual production, often encounter the plate thickness to be processed more than the bending machine allows
