Metallurgical slag sampling device and usage thereof

Abstract

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 improved effectively, quality stability and sampling success rate of high-temperature slag sampling are improved, online automatic sampling for metallurgical high-temperature slag is achieved, and further increase in the metallurgical automation level is facilitated.

Description

technical field [0001] The invention relates to an online sampling device for metallurgical slag in a high-temperature molten state at a production site and a method for using the device, and belongs to the technical field of metallurgical sampling devices and methods. Background technique [0002] In the field of iron and steel metallurgy, the composition detection of molten steel top slag is an important means to ensure the smooth production of steelmaking and improve the cleanliness of molten steel. In the process of molten steel smelting, it is the key to guide production and control quality to grasp the composition data of molten steel top slag in time. At present, the slag sampling method commonly used in metallurgical production is to manually use a simple iron sampling spoon to insert into the high-temperature slag, take out the high-temperature slag, pour it into the slag mold or directly dump it on the platform at the operation site, this kind of sampling The meth...

AI Technical Summary

Problems solved by technology

[0003] First, use a slag mold or directly dump the extracted slag on the on-site operating iron plate or cement platform. Due to the influence of the on-site operating environment, the high-temperature slag is easy to stick to impurities, which affects the accuracy of the detection of the slag sample composition;

[0004] Secondly, the metallurgical production site is a high-temperature operation area, and the operating environment is relatively harsh. When using a simple sample spoon to sample, the working conditions of the on-site workers are difficult, which affects the quality of sampling work. At the same time, the operating skills of the operators are different, and the sampling quality is also unstable;

[0005] Furthermore, the simple sampling method is not conducive to the automation of the production site, and cannot adapt to the development requirements and trends of metallurgical equipment automation and intelligence

[0006] In short, the manual and simple slag sampling method commonly used at present is not conducive to the guarantee of slag sampling quality, the stable detection of slag components, the improvement of on-site operation environment, and the further improvement of metallurgical automation. be improved
