冶金用盛渣车 (或渣罐车 )倾转装置上的大螺母是装在渣车翻转装置的丝杠上 ,螺母内有梯形螺纹 ,沿着旋转的丝杠运动而驱动渣罐翻转。螺母受应力和摩擦相当大 ,属于承载大、速度小的耐磨零件。因此要求材质应具有好的力学性能和耐磨性能 ,从 80年代末期开始 ,我们和本溪钢铁公司
Metallurgical slag truck (or slag truck) tilting device on the large nut is mounted on the slag car turning device screw, the nut has a trapezoidal thread, screw along the rotation of the movement of the slag tank driven flip. Nuts by a considerable stress and friction, belonging to the bearing large, small wear-resistant parts. Therefore, the material requirements should have good mechanical properties and wear resistance, from the late 80s, we and Benxi Iron and Steel Company
