Description
Technical Field
The utility model relates to a hot rolling steel pipe production field especially relates to a carry roller bed equipment and system of hot steel pipe.
Background
The long-term use of hot-rolled steel pipe conveying roller equipment can cause serious abrasion of the conveying roller or obvious collision damage on the surface of the roller due to the influence of high temperature and impact, and can not ensure long-term stable effective operation. Thereby causing the continuous regular roller way on the surface of the steel pipe to be scratched and influencing the quality of the outer wall of the product. In the prior art, hot-rolled steel tube factories adopt modes such as regular batch replacement or online grinding to solve the problem of roller bed scratch. However, the problems of long grinding time, high frequency, influence on yield and high maintenance cost occur occasionally, and the quality problem of the outer surface of the product is caused by the abrasion of the conveying roller way and the collision of the surface. In order to save the quality problem of the outer wall of the steel pipe, a large amount of manpower and material resources are required to be invested for grinding, so that the aims of improving the yield and reducing the cost are fulfilled.
Therefore, the utility model provides a carry hot steel pipe's roll table equipment and system to greatly improved the high temperature wearability on roll table surface, and shock resistance, thereby effectually solved the scotch problem of roll table to hot steel pipe, played important effect to product outer wall stable in quality.
