Description
Technical Field
The invention relates to the technical field of continuous casting and hot rolling production in a steel mill, in particular to a production control method and system for a continuous casting-hot rolling production line in the steel mill.
Background
Continuous casting and hot rolling are two major links of steel production in steel mills, wherein a continuous casting production line casts liquid steel into billets through a continuous casting machine, the continuously cast billets are conveyed to a hot rolling production line through a roller way, and the billets are produced into hot rolled steel coils through processes of heating furnaces, rough rolling, finish rolling, curling and the like in the hot rolling production line. The hot rolled steel coil has a unique steel coil number when a production plan is carried out, all information of the steel coil, including customer information, contract information, raw material proportion, rolling process parameters and the like, can be inquired in a production system through the number, the steel coil is cast according to the production plan in the production system and enters a hot rolling production line for rolling, and each steel coil is produced according to the production plan sequence. However, since the continuous casting line and the hot rolling line respectively use respective automatic systems, and a plurality of continuous casting lines are butted with one hot rolling line, when one of the continuous casting lines temporarily stops production due to unexpected factors, the steel billet which should be produced originally does not enter the next process, the sequence of the steel billet produced by continuous casting is changed, and the subsequent hot rolling line is executed according to the production plan sequence, so that the steel billet is hot rolled according to wrong production process parameters, and the steel mixing defect occurs.
The scheme for solving the steel mixing problem in the current production line is divided into two types: one is the machine number spraying: after the casting of the steel billet is finished, spraying a corresponding steel coil number on the side surface of the steel billet through a number spraying machine, and identifying whether the steel coil number corresponds to the steel coil number before entering a heating furnace of a hot rolling production line; the other is an artificial spray mark: manually spraying the mark after the billet is cast, and checking whether the mark corresponds to the billet before entering a heating furnace of a hot rolling production line.
