Embodiment Construction

[0020] refer to figure 1 As shown, the present invention discloses a strip return control device after the continuous annealing furnace is shut down, including: a mode selection device 102 , an actuator 104 , an automatic tension control mechanism 106 , an automatic time control mechanism 108 and an operation console 110 .

[0021] The mode selection device 102 receives the mode selection instruction, and selects one of the automatic tension mode, the automatic time mode and the manual mode.

[0022] The actuator 104 is connected to the equipment of the continuous annealing furnace, and the actuator 104 instructs the equipment of the continuous annealing furnace to perform a strip return operation or a tension reduction operation.

[0023] The automatic tension control mechanism 106 is connected to the mode selection device 102 and the actuator 104. When the mode selection device 102 selects the automatic tension mode, the automatic tension control mechanism 106 controls the a...

Abstract

The invention discloses a band steel return control apparatus after the shutdown of a continuous annealing furnace. The apparatus comprises a mode selection device, an execution mechanism, an automatic tension control mechanism, an automatic time control mechanism and an operation table, wherein the mode selection device can select one of an automatic tension mode, an automatic time mode and a manual mode; the execution mechanism indicates equipment of the continuous annealing furnace to execute a band steel return operation or a tension reduction operation; the automatic tension control mechanism controls the execution mechanism to gradually reduce the tension of the continuous annealing furnace in time period; the automatic time control mechanism controls the execution mechanism to uniformly return the equal-length band steel with the work segment as a base in time period; and the operation table receives a manual operation instruction, and controls the return operation of the execution mechanism to be carried out according to the manual operation instruction when the mode selection device selects the manual mode. According to the invention, the band steel can be automatically returned to the furnace after the abnormal shutdown of the technical segment of the continuous annealing furnace, so problems comprising band breakage, furnace deformation, furnace roller displacement and the like can be effectively prevented.

Description

technical field [0001] The invention relates to the field of metallurgical automation, in particular to a strip return control device after a continuous annealing furnace is shut down. Background technique [0002] The process section of the continuous annealing unit under normal production status is not allowed to stop. Under abnormal circumstances, after the process section is shut down, the furnace heating device stops immediately, and the temperature in the furnace drops rapidly, causing the strip steel to shrink and the strip steel tension to rise rapidly. If it is not controlled, it will lead to many problems such as broken belt, ladle warp, furnace deformation, furnace roller shift and so on. [0003] The application number is "200510028320.9", and the patent application titled "Method for Automatic Identification of Strip Deviation in Continuous Annealing Furnace" discloses an image recognition method for strip deviation in continuous annealing furnace. This method...
