Description

Technical Field

[0001] The present invention relates to the technical field of steel production, and in particular to a system and method for air-cooling driving an excitation component of a high-speed wire finishing mill LCI transmission system. Background Art

[0002] The cooling fan in the excitation section of the high-speed wire finishing LCI transmission system is controlled solely by a circuit breaker, without an intermediate buffer control link. Furthermore, the circuit breaker is frequently used by each production rolling shift, which can easily damage the circuit breaker and lead to accidents. Specifically, during normal production rolling, when process personnel need to stop the finishing area for inspection, an emergency stop and a corresponding power outage are required in the finishing area. This requires a power outage on the cooling fan control circuit breaker, which must then be powered back on after the process personnel have completed the inspection. This operation occurs several times per shift.

[0003] The most important thing is that each time power is restored, there are at least 10 minutes before steel rolling. However, since power has been supplied at this time, the cooling fan and the supporting fan of the excitation part of the high-speed wire finishing LCI transmission system are already in a rotating state, which will cause power consumption waste before the actual steel rolling. In summary, first of all, there is no buffer link, which causes damage to spare parts and related equipment accidents. On the other hand, the existing technology can only start the machine in advance, which causes waste of electricity. Therefore, the present invention proposes a system and method for air-cooled drive of the excitation component of the high-speed wire finishing LCI transmission system to solve the problems existing in the prior art.

A method for air-cooling the excitation assembly of a high-speed wire finishing mill LCI transmission system, characterized in that: The method is implemented by using the air-cooled drive system of the excitation component of the high-speed wire finishing LCI transmission system according to any one of claims 1 to 6, comprising the following steps: Step 1: Design the dry contacts of the LCI control system A500 control unit to drive the contactor through dry contact docking and linkage drive control system; Step 2: Design a closing linkage drive unit through dry contact docking and linkage drive control system, and perform timing control on the dry contacts of the A500 control unit of the LCI control system; Step 3: Design the dry contact action status monitoring and bright spot visualization display system of the LCI control system A500 control unit through action status monitoring and sequential logic control system, track the feedback closed-loop state of the dry contact action status, and provide accurate quantitative feedback and bright spot display of the dry contact action status; Step 4: Design the closing timing logic through the action status monitoring and timing logic control system. When the entire system is closed, the normally open dry contact output is controlled, the contactor is attracted, and the cooling fan starts to run; Step 5: Design the tripping timing logic through the interconnected drive and digital signal control system. When the entire system is tripped, the normally open dry contacts are controlled to stop outputting, the contactors are disconnected, and the cooling fans stop running. Step 6: Design a circuit breaker action status detection and digital signal conversion system through a connected drive and digital signal control system. This system detects the closed or open status of the power input circuit breaker that controls the cooling fan of the excitation part of the high-speed wire finishing LCI transmission system, and converts the status signal into a digital signal to monitor the power input. Step 7: Design a contactor action status detection and digital signal conversion system through the power control and time sequence power consumption reduction system to detect the pull-in or disconnection status of the power output contactor that controls the cooling fan of the excitation part of the high-speed wire finishing LCI transmission system, thereby monitoring the power output; Step 8: Design the timing relationship between the closing system and the on-site equipment transfer and steel rolling through the power control and timing reduction system. Plan the timing relationship between the closing system and the production equipment transfer and steel feeding, as well as the time quantitative comparison relationship, to maximize power consumption savings.
