Wide-band thin stainless steel rolling equipment and wide-band thin stainless steel hot rolling process

Abstract

The invention discloses wide-band thin stainless steel rolling equipment and a wide-band thin stainless steel hot rolling process. The steel rolling equipment comprises a rough rolling device, a finish rolling device and a coiling device, wherein the finish rolling device is arranged on one side of the rough rolling device, and the coiling device is arranged on one side of the finish rolling device. According to the equipment, a strip steel interception device is arranged and is used for collecting waste strip steel on a rolling line, so that normal rolling production work can be effectively prevented from being influenced by the waste strip steel, under the combined action of a transmission box and a push rod device, side guide plates can get close to a rolling center line in a synchronous and symmetric mode so as to get close to precisely center the strip steel, and the situation that steel heaping occurs or the side guide plates are impacted by the strip steel due to the fact that centering deviates is prevented from occurring.

Description

technical field [0001] The invention belongs to the technical field of integrated production of stainless steel casting and rolling, and in particular relates to a wide-band thin-plate stainless steel rolling equipment and a hot rolling process thereof. Background technique [0002] At present, in the steel rolling industry, the narrow band is defined as the band less than 1m, and the band is defined as the band greater than 1m. What’s more, the steel band greater than 0.6m and less than 1.2m is defined as the medium band. Strictly speaking, the strip greater than 1.2m Steel strips less than 1.7m are defined as broadband, especially for broadband stainless steel composite panels, the steel strip is wider, the surface area exposed to the air is larger, and the surface quality control of the steel strip is more difficult; generally the thickness is ≦0.3mm, as thin as 0.01mm stainless steel is called ultra-thin stainless steel. It belongs to the field of stainless steel special...

AI Technical Summary

Problems solved by technology

[0003] And the following problems easily occur in the existing wide-band sheet rolling production process: 1) scrap steel will be produced in the rolling process, and the scrap steel will not be collected in time and will affect the normal rolling work. 2) In the process of strip centering, there will be dimensional deviations that will cause the strip to hit the side guide plate or the accident of stacking steel. Once the deviation occurs, the stainless steel of the wide-band thin plate will be twisted and deformed, which will affect the wide-band thin plate. The quality of stainless steel
