滚子热轧是将加热的棒料沿轴向送入两个同一方向旋转的孔型轧辊中,利用轧辊凸棱(螺旋沟槽)逐升而使所包容的金属体积不变,并依毛坯连接颈长度和轧辊凸棱宽度变化相应的原理轧制成型。我厂热轧滚子用的设备为φ25～40毫米热轧机,轧辊是由一个深孔型、一个浅孔型和一双旋转的轧辊组成。轧辊的相对倾斜角为5°20′。轧制温度为860℃。轧机传动原理如图1所示,轧制原理如图2a和b所示。
Roller hot rolling is the heated bar along the axial direction into the same direction of rotation of the hole-type roll, the use of roller convex edge (spiral groove) so that the volume of the metal does not change, and according to the rough Connection neck length and the width of the convex roller ridge corresponding to the principle of rolling molding. Hot-rolled roller plant with the equipment for φ25 ~ 40 mm hot rolling mill, the roller is a deep hole type, a shallow hole type and a pair of rotating roller composition. Roll relative tilt angle of 5 ° 20 ’. The rolling temperature is 860 ° C. Mill drive principle shown in Figure 1, the rolling principle shown in Figure 2a and b.
