Tungsten-molybdenum mill biting device and tungsten-molybdenum mill
In the rolling process of tungsten and molybdenum sheet, especially for the rolling parts of large size and wide width, due to the large size of the sheet, if the rolling material appears small position deviation in the rolling conveying process, it will cause the accumulation of error. In this way, when the rolling material bites into the platform, there will be friction between the rolling material and the biting platform, and the friction is more serious. The friction of the rolling material bites into the platform, which not only affects the quality of the rolling material, but also causes damage to the structure of the biting platform and reduces the service life of the biting platform.
In addition, it is difficult to bite into tungsten and molybdenum sheet during the rolling process, which leads to the increase of defects such as delamination and coarse grain after rolling.
Therefore, how to solve the defects of tungsten and molybdenum sheet after rolling, such as delamination and coarse grain, has become an urgent problem for technicians in this field.
The invention relates to a biting device for a tungsten-molybdenum rolling mill and a tungsten-molybdenum rolling mill equipped with the biting device. The biting device comprises a mounting groove member having a mounting groove arranged on a tungsten-molybdenum rolling mill and located below a guide surface of a biting platform of a tungsten-molybdenum rolling mill; Used to contact with rolling parts of the free, the free wheel includes a mounting shaft, on the outside of the mounting shaft can be rotated with a wheel, the free wheel is arranged in the installation slot, and the stick can be rotated in the installation slot, the upper end of the stick for the guide outwardly protruding to roll contact with rolling parts. Through the technical scheme provided by the utility model, the friction mode between the rolling slab and the biting platform is changed from sliding friction to rolling friction, which reduces the friction force between the slab and the biting platform, makes the rolling piece bite smoothly, improves the biting ability of the rolling mill, avoids the appearance of defects such as delamination and coarse grain, and ensures the smooth production.
We can produce the molybdenum sheet and tungsten sheet according to your demand.
