Description
Technical Field
The invention relates to an online temperature detection device, in particular to an online roll surface temperature detection method and device.
Background
In the casting process in the vacuum furnace, molten steel at about 1500 ℃ is cast on a copper roller rotating at high speed to obtain a rapid quenching strip. Because the water cooling copper roller is adopted, in order to guarantee the safety of the use of the copper roller and the quality of products, the surface temperature of the copper roller needs to be detected.
The existing testing means comprises contact type temperature measurement and non-contact type temperature measurement, if a contact type thermocouple which is not subjected to any treatment is used for measurement in the contact type temperature measurement, the contact degree of a thermocouple head and a copper roller rotating at a high speed is different, so that the difference between the measured temperature and the actual temperature is too large, the copper roller is scratched, and the thermocouple head is damaged.
The non-contact infrared temperature measuring device is mature in technology for measuring some static objects or high-temperature objects, but cannot accurately measure the surface temperature of the copper roller due to the influence of working conditions such as high-speed rotation, high reflectivity, surface smoothness change along with time and the like in the casting process; the interference of smoke can be generated in the casting process in the vacuum furnace, and even the infrared temperature measuring device can not be used for measuring.
Shanghai BaoXin software GmbH reported a method and a device for monitoring the state of a crystallization roller (CN 102463328A). The device uses the infrared scanning crystallization roller method to measure the surface temperature of the crystallization roller. The crystallization roller made of metal has higher reflectivity, so that the test is inaccurate. Under the condition of long-time production, oxide skin is generated on the surface of the crystallization roller in a non-vacuum environment, the thermal conductivity is reduced, and the test error is large. The test error is greatly increased by the influence of the glossiness of the surface of the crystallization roller and the distance between the infrared scanner and the crystallization roller.
Baoshan iron and Steel products Inc. discloses a temperature measuring device (CN 201172098Y) for the roll surface of a crystallizing roll. The temperature measuring system provided with the spring tightly presses the crystallization roller and is positioned right below the crystallization roller, the device can measure the temperature of the surface of the crystallization roller in real time, the crystallization roller is not scratched, the thermocouple head is protected from being damaged, and the method is simple. However, when the soft crystallization roller is under pressure for a long time, local deformation defects are inevitably generated, and the integrity of the crystallization roller is damaged. The spring is always in a compressed state, has a limited life and is prone to failure. If the crystallization roller needs polishing and grinding, the thermocouple can be damaged by dust, and the diameter of the grinded crystallization roller is reduced due to the limited extension amount of the spring, so that the thermocouple head can be in poor contact with the crystallization roller, and normal measurement cannot be performed.
Qingdao cloud road new energy science and technology ltd reports a method for measuring the surface temperature of a high-speed rotary crystallizer and a device thereof (CN 102914387A). The contact degree of the thermocouple head and the surface of the copper roller in the strip spraying process is controlled, the temperature of the copper roller in the strip spraying process and before the strip spraying process is measured, the difference value is calculated, and the temperature of the surface of the copper roller is indirectly measured. The method is simple and ingenious, is low in cost, is greatly influenced by the jumping of the copper roller and the uneven degree of the expansion of the copper roller, and the response of an expansion measurement system can lag behind the factors, so that the adjustment cannot be carried out in time, and the desired temperature point is easily missed to be measured. What is more neglected is that the air heat at the thermocouple head before the spraying zone is too much different from that in the spraying zone, and the difference is not measured and calculated, so that the error is large.
Therefore, it is urgently required to develop a device capable of accurately detecting the surface temperature of the copper roller during the casting process in the vacuum furnace.
