Problems solved by technology
[0002] At present, a speed detection device is installed on the transmission device of the continuous casting stretching and leveling machine, but this technology can only detect the running speed of the transmission device when the continuous casting machine draws steel, and cannot detect the actual running speed of the billet when the continuous casting machine draws steel Therefore, when the billet clamping occurs during the casting machine drawing process, the original equipment will display that the casting machine drawing steel is normal, but the actual casting billet has stopped running in the casting machine, thus delaying the troubleshooting time and leading to more serious accidents Occurs and has a negative impact on normal production

Embodiment Construction
[0023] A continuous casting slab speed detection device, such as figure 1 As shown, it includes a measuring roller, a speedometer, a PLC control system, an alarm system and an HMI operating system. One end of the speedometer is connected to the measuring roller, and the other end is connected to the PLC control system; the PLC control system is respectively connected to the alarm system and the HMI operating system.
[0024] The speedometer can adopt encoder, infrared speedometer or laser speedometer. Such as figure 2 As shown, the PLC control system includes a regulated power supply, a power module, a CPU central processing unit, a communication module, a counting module and a digital I / O module. The controller is respectively connected with the communication module, the counting module and the digital I / O module. Such as image 3 As shown, the alarm system includes a relay and an alarm, and the alarm is connected to the PLC control system through the relay. Such as Fi...

The invention relates to a device and a method for detecting the speed of a continuous casting blank. The device comprises a measuring roller, a velometer, a programmable logic controller (PLC) control system, an alarm system and a human machine interface (HMI) operating system, wherein one end of the velometer is connected with the measuring roller, and the other end of the velometer is connected with the PLC control system; and the PLC control system is connected with the alarm system and the HMI operating system. The method for detecting the speed by utilizing the device comprises the following steps of: arranging the liftable measuring roller at a tapping hole of a casting machine, so that the measuring roller is lifted and butts against the casting blank; when the casting blank moves, running the measuring roller passively with the casting blank; acquiring and calculating detected speed signals by the PLC control system to obtain the actual speed during the movement of the casting blank; and comparing the actual speed during the movement of the casting blank with the speed of a steel drawing transmission device of the casting machine, and if an alarm happens, taking steps in time. By the device and the method, the actual speed of the casting blank in the casting machine is obtained accurately, a failure rate is reduced, and the production can be performed stably and smoothly.
