Abstract

The invention discloses a temperature measurement and sampling device of molten steel. The device comprises a sampling part, a thermocouple part, a paper sleeve part and a metal cap. The sampling part comprises a quartz tube, resin precoated sand and a sampling sample box. The paper sleeve part comprises a paper outer sheath tube and a paper inner sheath tube. The thermocouple part comprises a U-shaped quartz tube, a thermocouple pouring material, a thermocouple mud head, a precious metal wire and two compensation lead wires. The thermocouple part and the sampling part are placed in the paper sleeve side by side. The quartz tube of the sampling part and the U-shaped quartz tube of the thermocouple part are covered by the metal cap. The device can simultaneously achieve sampling and temperature measurement of molten steel, and meanwhile take out samples as quickly as possible. In the steel smelting process, temperature measurement is conducted while sampling is performed on the molten steel, so operation steps are simplified, the time for sampling analysis is shortened, labor intensity of workers is relieved, the cost is lowered, and the requirement for quickening steel smelting rhythms is satisfied.

Description

Technical field [0001] The invention relates to a temperature measurement and sampling tool used in iron and steel smelting, in particular to a device capable of simultaneously realizing sampling and temperature measurement. Background technique [0002] Molten steel sampling is to quickly take out samples from liquid molten steel for rapid spectral analysis, so as to obtain the composition and homogeneity of the molten steel in the furnace, which is used to guide the smelting process. The basic premise for accurately collecting data such as molten steel temperature and composition is that the time from sampling to obtaining analysis results is as short as possible. If the sampling speed is slow, the analysis results of sophisticated instruments are of no reference value. Therefore, the sampling speed is the key, and the development of a simple and fast sampler is the key to the success of the spectrum analysis before the steelmaking furnace. The traditional sampler is to bury ...
