Abstract

The invention discloses an automatic jacking device for a molten steel tank of an RH vacuum refining furnace and a control method, the device can comprise a binocular camera, a jacking mechanism, a displacement sensor and a control system electrically connected with the displacement sensor, and the binocular camera is used for collecting the distance from the liquid level of the molten steel tank to the binocular camera; the jacking mechanism is used for jacking the molten steel tank by a preset distance, the displacement sensor is used for measuring the jacking distance of the molten steel tank, and the control system controls the jacking mechanism to act according to data collected by the binocular camera and the displacement sensor so as to achieve automatic jacking of the molten steel tank. Further, the dip pipe is always kept to enter the molten steel by 0.5 m during production. The device is convenient to install, high in automation degree and capable of greatly improving the production efficiency, reducing the cost and improving the product quality.

Description

technical field [0001] The invention belongs to the field of molten steel desulfurization in the metallurgical industry, and in particular relates to an automatic jacking device and control method for an RH vacuum refining furnace molten steel tank suitable for a molten steel desulfurization system. Background technique [0002] RH (the acronym of Rheinstahl (Rheinstahl) and Heratus (Heraus)) vacuum refining furnace is an indispensable steelmaking and refining process in modern steelmaking plants, and is used in the production of special steels such as low carbon steel and low hydrogen steel. has an irreplaceable role. The intelligent development of the iron and steel industry is one of the main directions of the technological development of the iron and steel industry. Intelligentization and automation of the RH vacuum refining furnace The automatic jacking control of the molten steel tank is the "stuck" link in the development of a one-button automatic vacuum. At present...
