Abstract
A molten steel continuous temperature measurement sensor comprises a pedestal. A thermocouple is tube is disposed on the pedestal. A protective tube is disposed on an outer side of the thermocouple and is fixed onto the pedestal. Fillers for blocking oxidation atmosphere and reinforcing insulation are arranged between the thermocouple tube and the protective tube. A conversion apparatus which converts the thermocouple information acquired by the thermocouple tube into electrical signals is disposed on the pedestal. The molten steel continuous temperature measurement sensor is simple in structure, long in service life and is cheap, and has the measurement precision which satisfies production requirements.
Description
Technical field
The utility model relates to a kind of temperature probe, is specifically related to a kind of Continuous Temperature Measurement Sensor for Liquid.
Background technology
Metallurgical process online measuring technique is the important supplement of offline inspection technology, developing metallurgical sensor and detection system is in order to adapt to the continuous flow procedure technological requirements such as smelting, have important practical significance, for metallurgical continuous flow procedure, online detection combines with offline inspection technology, undoubtedly can be to improving metallurgical production technique, realize metallurgical process robotization control, minimizing quality accident brings about tangible results.Metallurgical sensor and detection system are the urgent need products of metallurgy industry become must obligato important tool in metallurgical production rubbish journey.
In field of steel-making, along with improving constantly of the kind to steel and quality requirements, continuous casting production process needs to measure exactly continuously the temperature of Metal in Tundish, liquid steel temperature is stabilized in certain scope and guarantees continuous casting billet quality.Broad research of continuous measurement of molten steel temperature technology various countries, but be all subject in actual applications the impact of the factor such as sensor cost and technology, do not promoted, both cheapnesss are all being found by each state, life-span is long again, and measuring accuracy meets the practical continous temperature measuring sensor of need of production.
Summary of the invention
