目前,三辊轧机仍是小型轧钢厂的主要设备,但在结构上存在一些问题,如压上装置即为其中之一。 压上装置是三辊轧机的下辊调整机构,调整是否方便、灵活,直接影响着产量和质量。现在使用的压上装置大多数为锯齿形螺纹结构。 (如图1) At present, the three-roller mill is still the main equipment of the small rolling mill, but there are some structural problems, such as the pressure on the device is one of them. Pressure on the device is a three-roll mill under the roll adjustment mechanism, the adjustment is convenient and flexible, directly affects the production and quality. Most of the pressure-applying devices currently used are serrated threads. (Figure 1)
