Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill production auxiliary equipment, in particular to a water return type rolling mill bottom box device. Background Art

[0002] During the production and use of rolling mills, it is usually necessary to cool the hot-rolled steel from the high temperature at the end of rolling to room temperature. Post-rolling cooling will affect the performance and appearance of the rolled material, and sometimes also affect the output of the rolling mill. Post-rolling cooling control is to control the coiling temperature of the strip, the intermediate temperature ultra-fast cooling outlet temperature, the cooling rate and the cooling path according to the process requirements. Its control accuracy directly affects the quality and performance of the product. However, the post-rolling cooling process is a complex heat transfer process, which includes radiation heat transfer, convection heat transfer, contact heat transfer between the strip and the heat output roller, and the phase change latent heat generated by phase change during the cooling process; among them, water-cooled convection heat transfer is also related to many factors such as the material of the strip, the final rolling temperature, thickness, speed, the amount of cooling water, water pressure, water temperature and water flow movement form, and the equipment working conditions of the cooling device. Post-rolling cooling will affect the performance and appearance of the rolled material, and sometimes also affect the output of the rolling mill. Post-rolling cooling can be divided into natural cooling, forced cooling and slow cooling according to the cooling intensity. According to different cooling methods, it can be divided into air cooling, pile cooling, wind cooling, water cooling, spray cooling, pit cooling, furnace cooling, etc. Different steels use one cooling method or a combination of two or more cooling methods according to their steel types and performance requirements.

[0003] The cooling water pipes of the rolling mill are installed on the rolling mill. Every time the mill is offline, check to see if there is any blockage.

[0004] Therefore, there is an urgent need to design a return water rolling mill bottom box device to solve the problem that the cooling water pipe can only be statically checked visually but cannot be dynamically checked. Utility Model Content
