Technical Field
The invention belongs to the technical field of billet continuous casting, and particularly relates to a billet fixed-length cutting redundancy system for small square billets.
Background
The steel billet cutting is a comparatively important ring in steel production, and in order to satisfy the demand of follow-up technology, the billet of conticaster production need cut into the steel billet of certain length through dedicated cutting equipment with continuous billet, and the cutting equipment that uses comparatively extensively at present mainly has hydraulic pressure to cut with the flame cutter, and whatever cutting mode, all need make clear and definite when the steel billet is cut, and will guarantee that cutting signal sends the continuity and the stability of cutting equipment.
For a multi-machine multi-stream continuous casting production system, if a sizing control system cannot accurately send a cutting signal to a cutting system, the existing emergency disposal scheme mostly adopts a manual cutting mode, and if the problem is not timely processed, unplanned shutdown is caused, and the stability and the continuity of production are seriously influenced.
Disclosure of Invention
The invention aims to provide a billet fixed-length cutting redundant system, which ensures the stable operation of the cutting system and ensures that the fixed-length system sends a correct signal to cutting equipment in the whole casting production process.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a little square billet sizing cutting redundant system, includes HMI system, flame cut quick-witted PLC, infrared scale equipment, the network camera of encoder, casting PLC, L1 system, the HMI headtotail of encoder through casting PLC and L1 system, the network camera is connected with infrared scale equipment, and infrared scale equipment passes through flame cut machine PLC and flame cut quick-witted HMI headtotail, is connected with the watchdog module between casting PLC and the flame cut quick-witted PLC.
Further, the encoder is installed at the tail of the withdrawal straightening machine.
Set up a set of infrared scale equipment outside encoder main scale cutting system, infrared scale equipment passes through the on-the-spot billet shift position of network camera detection, corresponding scale position is markd on the scene to set for corresponding scale cutting scale line in infrared scale system, corresponding cutting signal is through relaying with cutting start signal input to flame cut quick-witted PLC's digital quantity input module, and set for encoder and infrared scale switching button in flame cut quick-witted HMI system, under normal condition, the flame cut quick-witted procedure sets for encoder scale signal as main cutting signal.
In order to realize the redundancy switching between the encoder fixed length and the infrared fixed length, a watchdog module is additionally arranged between the casting flow PLC and the flame cut machine PLC, the status of a watchdog program is 1 in a normal state, when the communication between the casting flow PLC and the flame cut machine PLC fails, the watchdog point position is set in the flame cut machine program, and then the watchdog point position is actively switched to the infrared fixed length cutting signal program section, so that the rapid redundancy switching after the encoder cutting signal failure is realized.
The invention has the following beneficial effects: according to the invention, through the redundant switching of the two sizing systems, the quick switching can be realized when one sizing system fails, the unplanned shutdown accident caused by the failure of the sizing cutting system and the untimely problem handling is avoided, and the stable operation of the equipment is greatly ensured.

As shown in fig. 1, the billet sizing and cutting redundant system comprises an encoder 1 installed at the tail of a withdrawal straightening machine, an HMI system 3 of a casting PLC2 and an L1 system, an HMI system 4 of a flame cutter, a PLC5 of the flame cutter, an infrared sizing device 6 and a network camera 7. The encoder 1 is connected with an HMI system 3 of an L1 system through a casting PLC2, the network camera 7 is connected with an infrared sizing device 6, the infrared sizing device 6 is connected with a flame cutting machine HMI system 4 through a flame cutting machine PLC5, and a watchdog module 8 is connected between the casting PLC2 and the flame cutting machine PLC 5.
The method comprises the steps that an encoder 1 installed at the tail of a straightening machine is used as main counting and sizing equipment for sizing lengths of steel billets, from the beginning of casting, the numerical value of the encoder is converted into the actual production length of the steel billets through logic conversion of a casting PLC2, an HMI (human machine interface) system 3 of an L1 system is connected with a cutting length setting variable, when the accumulated counting of the lengths of program steel billets reaches the set numerical value, a program sends a cutting start point position, a cutting signal is sent to a flame cutter PLC5 through a TCP (transmission control protocol) network, and after the flame cutter PLC5 receives the cutting start signal, a clamping and clamping instruction is sent to an execution system of the flame cutter to start execution of a cutting program. When cutting is started each time, the steel billet cutting length is set to 0 by taking the holding and clamping action signal of the flame cutting machine as a trigger point, the length of the next steel billet is counted accumulatively, and the process is executed repeatedly when the set cutting length is reached.
