Embodiment 1

[0016] Embodiment 1: see figure 1 In this embodiment, a continuous annealing furnace with a preheating section, a heating section, a soaking section, a cooling section, an aging section, and a final cooling section is used. A dancing roll and a four-roll tensioning roll group are arranged in front of the furnace, and a four-roll sheet is arranged in the back of the furnace. Tight roller group, its process diagram is as follows image 3 shown.

[0017] In view of the above problems, the "one-key belt feeding" scheme is adopted after the continuous annealing furnace is shut down, which can effectively prevent the problem of steel strip bending in the furnace. The control flow chart is as follows figure 2 . The implementation is as follows:

[0018] Step 1: The front of the continuous annealing furnace is equipped with a BR3 tension roller set in front of the furnace, which is used to control the tension in front of the furnace and to cut off the tension; the pressure roller ...

Abstract

The invention relates to a control method for quickly feeding belts after the continuous annealing furnace is shut down. In this embodiment, the heating furnace has a preheating section, a heating section, a soaking section, a cooling section, an aging section, and a final cooling section. Dancing rollers, tension rollers and pressure rollers, a continuous annealing furnace with tension rollers and pressure rollers at the back of the furnace provides a method and device for one-key conveyance of strip steel in front of the continuous annealing furnace; this scheme combines conventional on-site multi- The one-step operation is simplified to remote "one-key" operation, which reduces the labor intensity of production operators, ensures rapid on-site operation and disposal, and ensures the safety of the strip steel in the furnace. It has the characteristics of saving time and effort, ingenious technology, and simple implementation. This scheme can effectively prevent the strip buckling and buckling deterioration effects after the continuous annealing furnace is shut down, and greatly reduce the occurrence of belt breakage accidents in the furnace after shutting down.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for rapid strip feeding after a continuous annealing furnace is shut down, and belongs to the technical field of cold rolling computer control. Background technique [0002] The continuous annealing furnace is the key equipment for producing high-quality cold-rolled ultra-thin strip steel. The strip steel is heated and recrystallized annealed in the annealing furnace to improve the microstructure of the strip steel and improve the plasticity and stamping formability of the strip steel. If the continuous annealing furnace is passively shut down due to a fault during normal operation, the temperature in the furnace will reverse and the tension of the strip steel in the furnace will rise. Even the vicious accident of breaking the belt has a great impact on the rapid recovery of the unit. Therefore, ensuring the safety of the strip steel in the furnace is the most important thing...
