A process facility for continuous casting slab weight determination based on neural network method

Abstract

The invention discloses a process facility and method capable of carrying out continuous casting blank basis weight based on a neural network method. The facility comprises a continuous casting blanklength, width and thickness real-time measuring device, a continuous casting blank temperature measuring device, a continuous casting blank casting speed measuring device, a tundish liquid face heightand molten steel temperature recording device, a crystallizer size and steel total amount recording device, a continuous casting blank density recognizing module, a continuous casting blank cutting device and a continuous casting blank weight measuring device. The length, the width, the thickness, the temperature and the pulling rate of a continuous casting blank, the tundish liquid face height,the molten steel temperature, the crystallizer steel total amount and other information are recorded at certain intervals, the neural network method is adopted to analyze collected continuous castingmachine and continuous casting blank big data, the influence factor of various continuous casting machine, molten steel and continuous casting blank parameters on the density of the continuous castingblank can be accurately recognized, the accuracy of the weight of the basis weight steel blank can be effectively improved, the yield is improved, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting, in particular to a process facility and method for determining the weight of continuous casting slabs based on a neural network method. Background technique [0002] At present, national standards and industry norms require that continuous casting slabs are cut into sections based on the fixed length of the slab, and the weight is not used as the basis for delivery, but is only a reference index. Due to the influence of the casting speed, molten steel temperature and crystallizer wear during the billet movement, the unit weight changes from time to time. The continuous casting billet of the same batch number basically differs by more than 40kg, or even exceeds 100kg. After the billet is rolled, the length of the steel The change is large, and the tail cannot be cut off or included in the indeterminate size material if it cannot meet the fixed length requirements, result...

Problems solved by technology

The disadvantage is that the adjustment target is not for the same continuous casting slab, and the change of working conditions will cause system instability and large weighing errors
