Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel production, more particularly, it relates to a control method of high-speed wire water tank. BACKGROUND

[0002] The water tank of the double high-speed wire of the rolling mill is very important, because the cooling efficiency and the cooling effect of the water tank are directly related to the quality of the finished product. If uneven cooling or delayed cooling occurs, it will cause the relevant finished product to appear local waste, and then the waste needs to be sheared, thereby ensuring the quality of the finished product.

[0003] At present, the control of the water tank is mainly based on signal triggering and distance tracking, time optimization for integrated control. There are ten water tanks in the high-speed area of the double high-speed wire. However, during the integrated control and optimization process, a new problem occurs. The best control effect based on integration will be affected by the differential degradation of the relevant water tank. That is to say, when the local components or water valves of each water tank respond to degradation, the corresponding water tank will become a short board, thereby affecting the control effect of the overall water tank. However, the existing technology can only control and dynamically optimize the ten water tanks in an integrated manner, which brings a bottleneck to the control and optimization of the entire water tank. Therefore, the existing technology has great drawbacks and defects, and cannot match the adjustment and optimization of the differential degradation of each water tank, thereby causing uneven cooling of the rolled piece, delayed cooling, and quality problems of the finished rolled piece, thereby reducing the yield during normal rolling. At the same time, due to the need to shear the tail at the shearing head, the labor intensity of the post personnel is greatly increased. Furthermore, due to the lack of a personalized adjustment and control system for the differential degradation of the water tank, it brings a bottleneck to the integrated control and optimization of the entire water tank, thereby further increasing the length of the waste rolled piece, thereby further reducing the yield and increasing the ton steel consumption cost.
