Automatic probe delivery and draw-out system capable of converter steelmaking endpoint parameter detection and liquid steel sampling and telescopic pipe assembly

Abstract

The invention provides an automatic probe delivery and draw-out system capable of converter steelmaking endpoint parameter detection and liquid steel sampling and a telescopic pipe assembly. The system comprises a rotating stand and an elevating part. The rotating stand is connected to a rotating drive. The elevating part is connected to the rotating stand. A multi-layer telescopic pipe assembly is mounted on the elevating part, and a lower end of the multi-layer telescopic pipe assembly serves as a coupling end for a compound probe. The multi-layer telescopic pipe assembly is provided with hollow cavities serving as compound probe pipe and line passages. A compound probe pipe/line deploying-retracting mechanism is mounted on the top of the rotating stand. An elevating drive for the elevating part is also mounted on the top of the rotating stand. The multi-layer telescopic pipe assembly is designed into a double-cylinder combination of both cylinders and pistons. The elevating part comprises a kinematic pair formed by a vertical guide rail connected to the rotating stand and a sliding plate, and the drive thereof. The multi-layer telescopic pipe assembly is connected to the sliding plate. The multi-layer telescopic pipe assembly is matched with the elevating part such that the overall height of the system is significantly reduced, and the rotating stand is driven by a motor to change working positions. Under the control of a converter control room workstation, accurate, safe and stable sampling and signal acquisition are achieved.

Description

technical field [0001] The invention relates to a converter steelmaking end point parameter detection and molten steel sample extraction probe automatic feeding system and telescopic tube assembly, which is used for converter steelmaking end point parameter detection and a composite probe for automatic feeding of molten steel sample extraction function The steel is subsurface and extracted from the device. Background technique [0002] In the production process of converter steelmaking, it is necessary to accurately detect technical indicators such as temperature, carbon content, and oxygen content of molten steel in the converter molten pool, especially the technical indicators of the final molten steel to ensure the quality of the final steel product. The traditional detection method is to turn the converter in a vertical state, turn it down, and manually sample the molten steel. After testing, analyze the temperature, carbon, and oxygen of the sampled molten steel, and de...

Problems solved by technology

However, at present, only a few large steel mills in China, such as Wuhan Iron and Steel, Baosteel, etc., adopt sub-gun detection technology, and other small and medium-sized steel mills are restricted by the following factors if they adopt this technology: first, the sub-gun equipment requirements The space is large and the factory is high enough; secondly, the cost investment is large, the general auxiliary gun equipment costs about 20 million yuan, and the maintenance cost can reach more than 4 million yuan, so currently only large furnaces with a capacity of 150 tons or more can be installed in China
