Visual and intelligent system and method for determining hot rolling temperature of steel coil

Abstract

The invention discloses a visual and intelligent system and method for determining hot rolling temperature of a steel coil, and belongs to the technical field of hot rolling. The system for determining the hot rolling temperature comprises a hot rolling first-stage system, a hot rolling second-stage system, a temperature detection device, an encoder, a data acquisition machine and a QMS managementapplication platform. According to the system, through input of the order information of a relevant steel coil on the QMS management application platform, Differentiation configuration of evaluationtolerances is performed in a server of the QMS management application platform according to the steel coil output event information, and the steel coil hot rolling temperature curve data collected onsite is transmitted to the QMS management application platform; and through development of a set function is developed and formulation of a quality factor on the QMS management application platform, the hot rolling temperature curve is analyzed and processed. Whether the hot rolling temperature of the steel coil to be detected is qualified or not is automatically judged, so that manual query workcan be greatly reduced, and the working efficiency and judgment accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of hot rolling, and more specifically relates to a visual and intelligent judgment system and method for hot rolling temperature of steel coils. Background technique [0002] The temperature control of hot rolling is the core of hot rolling process control, and the two most critical temperatures are the exit temperature of finishing rolling (abbreviated as: FDT) and the entrance temperature of coiling (abbreviated as: CT). The fluctuations of these two temperature controls not only directly affect the structure and performance of the hot-rolled sheet, but also affect the thickness accuracy, width accuracy, and plate shape of the product. As the customer's judgment range for product performance becomes more and more stringent, the concept of process steel judgment is also gradually formed. As an important part of the entire product production chain, the control of hot rolling temperature has gradually been i...
