Description

Technical Field

[0001] The invention relates to the field of quenching, and in particular to an online temperature measuring device for quenching. Background Art

[0002] Quenching heat treatment is a key process to improve the comprehensive performance of metal plates and strips, especially in improving their toughness, corrosion resistance, high temperature performance, fatigue performance, processing performance and other aspects. There are many types of metal plates and strips that are subjected to quenching heat treatment, such as: plain carbon steel, stainless steel, aluminum alloy, titanium alloy, high temperature alloy; the specification span is large, with a thickness of 2 300mm and a width of 800ˉˉ5000mm; the heat treatment process is complex, such as: solid solution, quenching, controlled cooling, weak water cooling, etc. The roller quenching machine has the advantages of strong cooling capacity, uniform cooling, high production efficiency, and good plate shape. It is the preferred equipment for quenching heat treatment of metal plates and strips. The equipment is designed with different cooling sections according to the cooling path requirements of metal plates and strips. It adopts cooling methods such as slit jets, multi-row inclined circular hole jets, and arc surface scattering jets. By controlling parameters such as water volume, water pressure, roller speed, and roller gap, the cooling process of metal plates and strips is accurately controlled to meet the diversified temperature drop requirements.

[0003] As users' requirements for the strength and toughness of metal plates and strips and their service performance gradually increase, many new technologies have been gradually developed in the roller quenching process, such as temperature-controlled quenching technology, quenching, partitioning, tempering (QPT) technology, sub-temperature / reciprocating / graded quenching technology, etc. By regulating the thermodynamics of the cooling process of metal plates and strips, controlling the phase change, precipitation and other processes, the strength and toughness of metal plates and strips can be further improved, and the processing performance such as corrosion resistance, wear resistance, fatigue resistance, high temperature performance, forming and welding performance can be improved. Whether it is the traditional quenching cooling path control, cooling rate control, or the newly emerging organization and precipitation control, it is necessary to obtain the temperature of the cooling process of metal plates and strips, and design the quenching heat treatment process according to the temperature, which is crucial for conventional heat treatment production and new product development. In the high-temperature metal quenching heat treatment process, there are various heat exchange forms such as nucleate boiling, film boiling, overboiling, and radiation heat exchange on the wall. The flow field, thermal field, phase field, and stress field are coupled with each other. The mathematical modeling of the quenching temperature field of metal plates and strips is very complex and has low calculation accuracy, poor reliability, and difficult model correction and learning. If the actual measured temperature value of the metal plate and strip quenching process can be directly obtained through the temperature measuring instrument, and the temperature of the metal plate and strip quenching heat treatment process can be controlled based on this, on the one hand, it can be used as direct data for process design and performance regulation, and on the other hand, it can be used as a correction value of the heat treatment mathematical model, which is very beneficial to quenching performance regulation and process automatic control.
