Metallurgy molten slag sampling device

Abstract

The invention discloses a metallurgical slag sampling device, which comprises a power processing box and a connecting rod. The connecting rod is arranged on the left side of the power processing Fixed connection, a forward current device is installed above the inside of the power processing box, and the forward current device is embedded in the power processing box. This kind of metallurgical slag sampling device has the function of automatic sampling, and after sampling, it is isolated from the outside world and will not The metallurgical slag reacts with the outside world, and the forward current device works, so that the motor drives the driving shaft and the driven shaft to pass forward. Since the sampling tube and the connecting block are welded, the connecting block drives the sampling tube to rotate counterclockwise, and the sampling tube is subjected to metallurgical The extrusion of slag, etc., the tube cover is opened inward, and the metallurgical slag enters the sampling tube. The high temperature resistant protective layer prevents the high temperature slag from damaging the sampling tube.

Description

technical field [0001] The invention relates to the technical field of metallurgical sampling devices, in particular to a metallurgical slag sampling device. 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, timely grasping the composition data of molten steel top slag is the key to guiding production and controlling quality. At present, the slag sampling method commonly used in metallurgical production is to manually use a simple iron sampling spoon to penetrate into the high-temperature slag, take out the high-temperature slag and pour it into a slag mold or directly dump it on the platform at the operation site. [0003] However, in the existing sampling method, due to the influence of the on-site operating environment, the high-temperature slag i...

Problems solved by technology

[0003] However, in the existing sampling method, 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 components of the slag and slag samples. The metallurgical production site is a high-temperature operation area, and the operating environment is relatively harsh. When sampling, 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. In addition, the simple sampling method is not conducive to the automation of the production site, and cannot adapt to the automation and intelligence of metallurgical equipment. Development requirements and trends are not conducive to the assurance of slag sampling quality, the stable detection of slag components, the improvement of on-site operating environment, and the further improvement of metallurgical automation.
