Study on laser texturing on cone roller surface

When the strip steel is rolled by the cone rollers,in order to strengthen the friction force between the cone roller surface and the strip steel,the laser texturing(LT) technology on the cone roller surface is adopted.The LT technology on cone roller surface was introduced.The composition of the LT equipment was presented.The control principle of the LT equipment was given.Because the processing process of LT on the cone roller surface is a process of changing diameter,in order to gain the same distance between two adjoining LT dots on the same processed circle,the computational formulas of the diameter,the number of LT dots and the frequency division coefficient on every processed circle must be worked out.The formulas were provided which can solve the problem that the distance between the last LT dot and the first LT dot is larger than the usual.The practical application shows that the LT on cone roller surface enhances the friction force between the cone roller surface and the strip steel and extends the life of the cone roller.
