Method for lowering installation height of Ruhstahl Hausen (RH) vacuum processing device under low rail surface elevation condition

Abstract

The invention belongs to the technical field of a steel-making Ruhstahl Hausen (RH) process, and in particular relates to a method for lowering the installation height of an RH vacuum processing device under a low rail surface elevation condition. The method for lowering the installation height of the RH vacuum processing device under the low rail surface elevation condition is characterized by comprising the following steps of: 1) lowering the top elevation of a top-blown oxygen lance: firstly, arranging an RH buggy ladle jacking device below a 0.000m plane at an RH vacuum processing position, and reducing the distance between the heat insulating frame of an RH buggy ladle and the 0.000m plane by 50 to 100mm; secondly, reducing the total height of a vacuum room by 700 to 800mm; and thirdly, optimizing the arrangement position of a top-blown oxygen lance inserting hole uncovering device on the top of the vacuum room; and 2) lowering the elevation of an alloy loading and charging system: arranging an alloy loading system, an alloy feed bin and a charging system in adjacent areas, and transferring an alloy from the alloy feed bin to the charging system by using a conveyer belt. The RH vacuum processing device can be installed by the method under the condition of insufficient crane rail surface elevation in an RH area in a steel-making workshop.

Description

technical field [0001] The invention belongs to the technical field of steelmaking RH technology, and in particular relates to a method for reducing the installation height of an RH vacuum treatment device under the condition of low rail surface elevation, so as to adapt to equipment installation under the low rail surface elevation. Background technique [0002] With the development of my country's national economy, the user's demand for steel products continues to expand, and the requirements for steel quality are also increasing. From the point of view of the process itself and experience, the RH series vacuum treatment technology has become one of the effective means to expand the product range and improve product quality. [0003] Most of the existing RH vacuum treatment devices in domestic steel mills are arranged offline, and there are various types of process design schemes such as single station, double station, and ladle rotating type. These process design schemes...

Problems solved by technology

This may not have any problem for the supporting RH vacuum treatment device in the new steelmaking plant, but for the addition of RH vacuum treatment device in the existing steelmaking workshop, there may be insufficient elevation of the crane rail surface in the RH area of ​​the steelmaking workshop, which cannot meet the requirements of the alloy. The setting requirements of the feeding device and the top blowing oxygen lance device at the processing position, at this time, it is necessary to seek a new process design scheme
