Description

Multi-multiple-length production system for long fixed-length steel plate Technical Field The utility model relates to the technical field of steel plate production, in particular to a multi-length production system for a long fixed-length steel plate. Background During the production of steel sheet, the panel design is a complex problem, which is limited by a number of factors, wherein the cooling bed length severely limits the large panel length in the panel design. The cooling bed is used as conveying equipment for cooling the steel plate in the steel plate rolling process, and the length of the cooling bed directly determines the maximum length of the rolled steel plate. The billet size cannot be increased without limit due to the limited length of the cooling bed, otherwise the length of the rolled steel plate exceeds the length of the cooling bed, and cooling and subsequent treatment cannot be performed. However, for current medium plate production, the variety of orders, the complexity of production scheduling, and the comprehensive consideration of multiple environmental factors all present challenges to the traditional process. The traditional process is difficult to meet the requirements of high precision and high efficiency, and particularly when various orders are produced, the traditional fixed blank size and rolling mode are difficult to flexibly adapt to the production requirements of steel plates with different specifications.
