Problems solved by technology

However, due to the difficulty of temperature measurement and sampling in a vacuum state, the current production process generally adopts artificially in the atmospheric environment before and after vacuum treatment.
As a result, it is difficult to grasp the state of the metal during vacuum treatment, especially to find various deviations during vacuum treatment, and then lose the opportunity to correct deviations in time
In addition, the operating environment for manual temperature measurement and sampling is poor, and it is necessary to wear high-temperature and radiation-resistant equipment

Abstract

A vacuum temperature measurement sampling system is characterized by comprising an automatic opening-and-closing vacuum chamber system and an automatic temperature measurement sampling gun system, wherein the automatic opening-and-closing vacuum chamber system is welded on an outer shell of a vacuum metallurgy container. The automatic temperature measurement sampling gun system comprises an automatic temperature measurement system sampling gun which is installed in the automatic opening-and-closing vacuum chamber system. The automatic temperature measurement system sampling gun comprises a paper tube probe which is capable of achieving self-sampling of molten metal in a melted steel bag in the vacuum metallurgy container due to the up-and-down movement of the paper tube probe. According to the vacuum temperature measurement sampling system and an operation method thereof, due to the fact that the automatic temperature measurement system sampling gun system is arranged in the automatic opening-and-closing vacuum chamber system, the automatic temperature measurement sampling gun can enters the vacuum metallurgy container for obtaining sample of melt steel at any time on the premise that vacuum environment of the metallurgy container is not damaged, process time is saved, operation environment of workers is improved, the operation method is simple and easy to implement, consistency of test conditions is guaranteed, and accuracy of a test result is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid metal treatment process in the field of metallurgy, and in particular relates to a system for sampling and measuring temperature of molten metal from an atmospheric environment into a vacuum container and an operation method thereof, which is suitable for various vacuum refining metallurgical equipment such as VD and VOD. Background technique [0002] In steelmaking production, vacuum refining plays a very important role in improving the quality of steel products, expanding varieties, reducing costs, and optimizing steelmaking production processes. Sampling, measuring temperature, determining hydrogen and oxygen directly on the smelted metal are important means to understand the metallurgical process and the quality of molten steel. However, due to the difficulty of temperature measurement and sampling in a vacuum state, the current production process is generally carried out manually in an atm...
