成型轧辊轧制直径的确定方法有两种:一种是按各架成型轧辊(下辊)底径相等的方法配置轧辊直径;另一种是按各架成型轧辊轧制线相等的方法配置轧辊直径。在确定成型轧辊的直径时,无论采用那种方法,均应在各成型架次之间增加0.5～0.65％的微拉力。以往我公司所使用的成型轧辊轧制直径的确定方法是按各架成型轧辊下辊底径为准,并以每架轧辊之间递增0.5～0.65％的微拉力,再按机组上、下轴速比确定上辊直径的方法计设制造轧辊的(见图一)。
There are two ways to determine the rolling diameter of the forming roll: one is to set the diameter of the rolls according to the method of equalizing the bottom diameter of each forming roll (the bottom roll); the other is to configure the rolls according to the method of equalizing the forming rolls of each frame. diameter. In determining the diameter of the forming roll, no matter which method is used, an increase of 0.5 to 0.65% of the microtensile force should be added between the forming passes. In the past, the method of determining the rolling diameter of the forming rolls used by our company was based on the bottom diameter of each roll forming roll and 0.5 to 0.65% micro-stretch between each roll, and then the upper and lower axes of the set. The method of determining the diameter of the upper roll is used to design the rolls (see Fig. 1).
