Problems solved by technology

[0012] Since the diameter of the inner tube of the temperature measuring tube is required to be much larger than that of the protection tube, the response speed of the infrared temperature measurement is even worse than that of the thermocouple under the condition that the service life of the two tubes is similar

Embodiment Construction

[0020] As can be seen from Fig. 1, the bottom of the present invention is a tubular temperature-measuring tube 9, the temperature-measuring tube 9 is a single-layer structure, its lower end is blind, the upper end is open, and a cylindrical taper shaft connector 6 is packaged at the upper open end; The temperature tube 9 meets the requirements of high temperature resistance, corrosion resistance, erosion resistance, thermal shock resistance, high thermal conductivity, and low density, and can be referred to as: a single-layer high-temperature-conducting temperature-measuring tube. The tube wall of the temperature measuring tube 9 is allowed to generate harmful gas substances and volatilize in its cavity, and the harmful gas phase in the molten steel is allowed to enter the cavity of the temperature measuring tube 9 through penetration and diffusion. The inner and outer surfaces of the blind end of the temperature measuring tube are designed with concentric spherical surfaces to...

Abstract

An infrared device can measure quick-response of liquid steel temperature continuously. It contains temperature tube, temperature gun, tubular conical connecter packaged on open end of temperature tube and measuring probe equipped in center of upper cavity. Upper open end of temperature gun is connected with a protective metal hose, which both as the delivery channel of cooling gas and laying channel of fiber optic cable, communication and power cable. Cavity outside protective shell of inner measuring probe of temperature gun is cooling gas channel. In the middle of temperature gun set a measuring locator with gas caulking ring. Tubular measuring locator is under gas caulking ring and there are many blow holds on their joint. A microtubule honeycomb duct spirals on central port of caulking ring. The conical connecter inserts in the measuring locator. The invention adopts special function of training temperature gun and monolayer temperature tube with high temperature conductivity to realize except baking, quick response and precious dynamic measuring of the temperature tube.

Description

technical field [0001] The invention relates to a measuring device for the temperature of molten steel in a molten pool. Background technique [0002] At present, steel mills generally use the method of manually inserting a "disposable fast thermocouple" to measure the temperature of molten steel. This method belongs to intermittent measurement, and the measurement interval is 5 to 10 minutes. Each measurement consumes a precious metal (platinum) thermoelectric Even for the price. Due to the slagging on the surface of the molten steel during the production process, when the slag layer is thick, the thermocouple cannot be inserted into the molten steel, resulting in a time blind zone in the measurement, affecting production control and even leading to production accidents. This measurement method: high cost; high labor intensity; not conducive to the realization of temperature-related automatic control of metallurgical production. [0003] Continuous temperature measurement...
