In-situ on-line detection device for metallurgy liquid metal component

Abstract

The invention relates to an in-situ on-line detection device for a metallurgy liquid metal component. The device comprises a front-end high-temperature-resisting optical probe, a middle-end signal generating and acquiring part and a rear-end control platform, wherein the front end of the front-end high-temperature-resisting optical probe is arranged in metallurgy liquid metal to generate an optical signal and is used for transmitting the optical signal to the middle-end signal generating and acquiring part; the middle-end signal generating and acquiring part is used for converting the received optical signal of the front-end high-temperature-resisting optical probe into an electrical signal and outputting the electrical signal to the rear-end control platform; and the rear-end control platform is used as a manual operation and display platform and is used for receiving the electrical signal transmitted by the middle-end signal generating and acquiring part, processing the received electrical signal, controlling a laser signal of the middle-end signal generating and acquiring part and controlling the flow of water and gas in the front-end high-temperature-resisting optical probe. By the device, detection time is greatly shortened, the quality of a product is substantially improved, production cost is reduced, and energy consumption is reduced; and the device has an accurate measurement result and can be used for measuring difficultly-measured components such as C, S, P and the like.

Description

technical field [0001] The invention relates to an on-line monitoring technology for high-temperature liquid components, in particular to an in-situ and on-line detection device for metallurgical liquid metal components. Background technique [0002] Metals and alloys need to detect changes in chemical composition during the smelting process to control product quality and judge the smelting end point. At present, due to the lack of advanced online measurement technology, the smelting process generally adopts the offline detection method of manual sampling and sample preparation. For example, in the process of steelmaking, the detection of high-temperature molten steel needs to go through a series of processes such as sampling, cooling, grinding, polishing, etc., and then take it to an analytical instrument for measurement and analysis. The whole process takes 3 to 5 minutes. It takes up more than one-tenth of the smelting time. This time-consuming off-line detection method...
