A temperature-displacement coupling device for real-time monitoring of on-line crystallizer copper plate

Abstract

The invention discloses a temperature displacement coupling device for real-time monitoring of a crystallizer copper plate in an on-line mode. The temperature displacement coupling device comprises a temperature sensing probe, displacement probes, a spring sliding channel, a guide rod, a clamping sleeve device, displacement compensating lead wires, a swivel nut, a fastener and a temperature compensating lead wire. Due to the fact that the thermocouple and displacement couple measures are taken, temperature variation and displacement variation under the condition that the crystallizer copper plate is heated can be monitored at the same time, the equipment reliability and stability of the crystallizer device are guaranteed, the overall breakout ratio of a continuous casting machine is lowered, and the economic benefits of a steel mill are increased. For the reason that the temperature sensing probe and the four displacement probes are adopted, the monitoring purpose can be achieved to the greatest extent under the condition that space is definite. The temperature displacement coupling device for the crystallizer copper plate and a crystallizer breakout prediction PLC system of the continuous casting control system are connected, so that timely monitoring of the on-line crystallizer copper plate is achieved, and the purpose of on-line control over the crystallizer copper plate is achieved.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery and equipment, in particular to a temperature displacement coupling device used for real-time monitoring of an online crystallizer copper plate. Background technique [0002] The mold is the heart of the steel continuous casting machine. It has been working in a harsh environment with limited space, continuous vibration, ambient temperature between -20 and 200 °C, a large amount of water vapor and a small amount of oil. [0003] The failure form of the mold copper plate is mainly manifested in two aspects: one is the denaturation of the copper plate material due to overheating and uneven temperature distribution of the mold copper plate, and the other is the deformation of the mold copper plate in the continuous casting environment (stress and thermal stress). Under the action, the copper plate is seriously deformed under stress. These two aspects will directly determine the material proper...

AI Technical Summary

Problems solved by technology

[0005] Since the copper plate of the crystallizer has a certain thickness and the installation space is limited, the thermocouple installation holes already have a certain density distribution on it. It will be difficult to add additional holes for the displacement monitoring device to the copper plate.

And adding a displacement monitoring device to the repair of the old mold copper plate will increase the processing capacity of the copper plate and reduce the performance of the copper plate
