Description

Hot Rolled Steel Strip Surface Grinding Information System

The invention relates to an information system for surface grinding of hot-rolled steel strips, especially an information system integrating information and grinding images of hot-rolled steel strips.

In the process of making the steel strip, in order to make the steel strip finally have the expected size, the size of the steel strip is usually adjusted through a rolling process. The rolling process can include hot rolling as well as cold rolling. Hot rolling uses slabs (mainly continuous casting slabs) as raw materials, and after heating, steel strips are made by rough rolling mills and finishing mills. Cold rolling takes hot rolled steel coil as raw material, pickling to remove oxide scale and then cold rolling, and the finished product is rolled hard coil. Before cold rolling, due to the defects on the surface of the hot-rolled steel coil, it needs to be slit to remove the defective part before the follow-up process can be carried out. The best treatment is to first carry out surface grinding treatment for the harmful defects of the hot-rolled steel coil, and then carry out related processes such as cold rolling, which can effectively reduce the problem of insufficient coil weight and further improve the productivity of cold rolling.

However, for the hot-rolled steel coil that has undergone surface grinding treatment for the defective portion, the thickness of the grinding portion is thin, and the types of grinding defects are also different. In addition, if the grinding place is located in the no-grinding zone of the hot-rolled steel coil, it is likely to cause strip breakage during cold rolling. Therefore, for the hot-rolled steel coil after surface grinding treatment, the information of the grinding place (eg, location, type, etc.) must be provided together with the cold rolling treatment to avoid the situation of strip breakage. The grinding information of the current hot-rolled steel strip is only reported for the grinding place, and the report only has simple numerical information (for example, the thickness, width of the steel coil, how many meters the grinding place is located in the steel coil, etc.), but there is no complete defect position information and corresponding information.
