Metallurgical slag sampling device and usage thereof

A metallurgical slag sampling device and usage thereof belong to the technical field of metallurgy and are useful in online sampling of high-temperature molten metallurgical slag on a production site. The technical scheme of the invention includes: the metallurgical slag sampling device comprises a paper protection sleeve and a glass vacuum sampling core; the vacuum sampling core is mounted in the protective sleeve and fixed via pug; a sampling actuator holds the protective sleeve and extends into slag on the surface of molten steel, after a moment of standing, the slag sampling device is taken out of the slag and cooled, and a slag sample is submitted for inspection after completely solidifying. The invention is innovation on metallurgical slag sampling processes, and the backward situation of present metallurgical slag sampling is changed. The metallurgical slag sampling device and usage thereof of the invention are simple and feasible, a field operation environment and labor intensity of workers are improv
