Abstract

The invention discloses online smelting sampling equipment used for laser inducing of plasma spectral analysis. A drive device is connected with a transmission device and drives the transmission device to enable a sampling staining rod connected with one end of the transmission device to move along a straight line. The other end of the sampling staining rod is inserted into an argon sealing sleeve. The argon sealing sleeve is provided with an argon inlet hole and a laser measuring hole. The lower end of the argon sealing sleeve is closed. According to the online smelting sampling equipment used for laser inducing of plasma spectral analysis, interference is avoided, and sampling is convenient.

Description

technical field [0001] The invention relates to the field of laser-induced plasma spectroscopy, in particular to a smelting on-line sampling device for laser-induced plasma spectroscopy analysis. Background technique [0002] Laser-Induced Plasma Spectroscopy (LIPS), also known as Laser-Induced Breakdown Spectroscopy (LIBS), is a quantitative analysis technique based on the emission spectrum generated by the interaction between laser and material. Quantitative analysis of components can be achieved with only a few micrograms of the tested material, which belongs to non-destructive testing technology. During the detection process using LIPS, the composition ratio analysis of substances in any physical state can be realized without sample pretreatment. Because LIPS technology has long-distance measurement and analysis capabilities, it is very suitable for high-temperature metallurgical field applications. The whole process of metallurgical on-line component analysis using LI...
