在轧管过程中向变形区投入润滑剂,在顶头与毛管内壁接触面上形成一层润滑膜,改变了变形区内顶头与毛管内壁的接触摩擦条件,从而使接触面的摩擦系数下降,使钢管内表面光滑,提高顶头的使用寿命.通过大量实验证明,014润滑剂性能最好,轧制过程稳定,是适用于自动轧管机组的良好润滑剂. In the rolling process to the deformation zone into the lubricant in the head and the capillary wall contact surface to form a layer of lubricating film to change the deformation zone head and the inner wall of the capillary contact friction conditions so that the contact surface friction coefficient decreased The inner surface of the steel pipe is smooth and the lifespan of the head is increased.It has been proved by a large number of experiments that the 014 lubricant has the best performance and the rolling process is stable and is a good lubricant suitable for the automatic pipe rolling machine.
