Problems solved by technology

[0002] At present, the operation control of casting machine accident handling at home and abroad cannot achieve real-time monitoring and feedback
Because the personnel who perform the operation cannot gain insight into the actual situation of the equipment, the handling of accidents and faults is slow, and at the same time, it is possible that the equipment will be further damaged or the repair time will continue to be extended due to misoperation.

Embodiment Construction

[0011] Place two industrial wireless APs (2.4GHz) on the casting machine platform, equipment on each floor and control room to detect the wireless signal strength of the casting hydraulic control valve station, secondary cooling water flowmeter and valve station, casting platform and sector area Whether it can meet the requirements of wireless terminals. After the test signal is passed, the location where the wireless hotspot is installed includes the hydraulic control valve station of the casting stream, the secondary cooling water flow meter and valve station, the casting platform and the segment area. At the same time, the specific operation interface and man-machine interface are edited and run in the handheld wireless terminal to realize real-time control of secondary cooling water, driving roller position and roller gap control, etc., and achieve the effect of interactive feedback detection and control.

Abstract

A method for controlling accident treatment equipment of 400mm extra-thick slabs belongs to the technical field of continuous casting in steelmaking, and includes: mounting wireless AP (access point) devices in a strand hydraulic control valve station, a secondary cooling water flowmeter and valve station, a casting platform and a segment position station of a casting machine, and accessing a PLC(programmable logic control) system network to the stations by means of Ethernet or optical fibers; turning on a handheld wireless terminal touch controller based on a Windows CE 6.0-6.5 system; starting the wireless network of the system to search accessible wireless AP IEEE802.11a / b / g / n; starting images of the equipment required to be controlled and testing whether the images of the equipment are normal or abnormal; controlling the following operations: regulating volume of the secondary cooling water by regulating the opening degree of a pneumatic diaphragm value by 0-100%, regulating the opening degree of a segment by the aid of hydraulic sensors of the segment and regulating actual slab drawing speed by regulating speed of driving rolls of the segment, by touching the images in the strand hydraulic control valve station, the secondary cooling water flowmeter and valve station, the casting platform and the segment position station which are required to be controlled. The method has the advantages of monitoring field conditions in real time and controlling action of the equipment.

Description

technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting, and in particular provides a method for controlling accident handling equipment for 400mm extra-thick slabs. After accidents occur in 400mm extra-thick slabs, special equipment can be used to monitor the site conditions in real time. And control the device action. Background technique [0002] At present, there is no real-time monitoring and feedback for the operation control of casting machine accident handling at home and abroad. Because the personnel performing the operation cannot gain insight into the actual situation of the equipment, the handling of accidents and faults is slow, and at the same time, the equipment may be further damaged or the repair time may continue to be extended due to misoperation. Contents of the invention [0003] The purpose of the present invention is to provide a method for controlling accident handling equipment for 400mm extra-thic...
