Single-station RH process arrangement method for rail crossing of two molten steel vehicles

Abstract

The invention discloses a single-station RH process arrangement method for rail crossing of two molten steel vehicles, and belongs to the technical field of steelmaking RH vacuum treatment. The method involves a buggy ladle system, a rail device and a jacking system. Two molten steel vehicles cross rails are designed, a steel ladle of molten steel to be treated are conveyed by one rail to reach a treatment position, the molten steel begins to be treated, after the treatment is finished, the steel ladle is transported to a continuous casting span bull ladle by the molten steel vehicle on the rail; a steel ladle is arranged on the molten steel vehicle on the other rail in advance, and when a buggy ladle is not at the treatment position, the molten steel vehicle on the other rail is driven to the treatment position for molten steel treatment; and in the process, two molten steel car transport tracks are subjected to cross operation and continuous operation is carried out, and the two rails have intersections at the molten steel transport line and the RH treatment position, and meanwhile, a transport vehicle on one rail is a special-shaped molten steel vehicle, so that the operations that the molten steel can be treated at the treatment position, a ladle cover can be picked off and hung on, and a stationary ladle is hoisted through a crown block are met. The single-station RH process arrangement method for the rail crossing of the two molten steel vehicles has the advantages that the RH vacancy time can be greatly saved, the influence of cold steel in a RH vacuum tank on molten steel component in the treatment process can be reduced, and the reasonable arrangement of the production organization can be facilitated.

Description

Technical field [0001] The invention belongs to the technical field of steel-making RH vacuum treatment, and particularly relates to a single-station RH process arrangement method in which two steel water wagon tracks cross. Background technique [0002] With the country's requirements for industrial upgrading and structural adjustment of the metallurgical industry, many steel companies have tried every means to optimize and upgrade the existing processes. Among them, the demand for RH refining equipment for smelting high-end automotive panels is becoming more and more common. RH vacuum treatment technology is an efficient method for refining outside the furnace and one of the effective means to improve product quality and expand product range. [0003] At present, the layout of the RH process molten steel transportation track in domestic steel plants has a variety of process layout schemes such as single station single steel car track, single station double track hydraulic jacking...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a single-station RH process arrangement method in which two molten steel truck tracks cross each other, so as to solve the high energy consumption of alternating cold and heat in the RH vacuum chamber of the steel plant and the impact of cold steel on production, and at the same time ensure single-station RH continuous smelting meets the continuous pouring requirements of a continuous casting machine
