Abstract
The invention relates to a method for building a new converter station in a steel plant room without stopping production of the station, which increases the converter station at the tail part of a molten iron incoming direction by analyzing an original plant room and utilizing an auxiliary high span adjacent to a high span of the steel plant room. The high span is formed into an independent stable system by adding the support, the auxiliary high span is locally improved, and a frame is added at the position of the auxiliary span to construct a converter platform. Because the station is added at the tail part of the incoming material and the high-span factory building forms a stable system, the original converter is not influenced by the reconstruction of the factory building to stop production, and the purpose of production preservation is achieved.
Description
Technical Field
The invention belongs to the technical field of metallurgy, and particularly relates to a method for continuously producing a new converter station in a steel plant without reserving the station.
Background
With the strict control of the steel production in China, newly-built metallurgical plants are gradually reduced, but the steel-making converter transformation project happens occasionally, and a new converter station is frequently added in the old steel-making plant. According to the general scheme, an original factory building is modified, a low span is dismantled, a high span factory building is newly built at the position of the dismantled low span factory building according to the process requirement, and then the stations of the converter are increased; the other scheme is that a converter factory building is newly built in an adjacent old factory building to form an independent structure system, so that the converter stations are increased. The two schemes have the problems of long production or construction period, high manufacturing cost and the like of the original converter. The invention is invented under the condition that a converter station is newly added in an old factory building.
Disclosure of Invention
The invention aims to provide a method for not stopping production of a newly-built converter station in a steel plant room without reserving the station, which adds the converter station in the original plant, does not influence the production progress of the original converter, and has short construction period and low manufacturing cost.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for building converter stations in a steel plant without stopping production of the steel plant without station reservation is characterized in that the station of the converter is increased at the tail part of a molten iron incoming direction by utilizing the position of an auxiliary high span adjacent to the high span of the steel plant.
The method specifically comprises the following steps:
1) a stable column support is added at the original high span, so that the original high span forms an independent stable system;
2) adding a new high-low span column support at the tail of the original auxiliary high span;
3) and cutting off the original secondary high-span column support, locally reforming the original secondary high span, and adding a frame at the position of the original secondary high span to construct a converter platform.
Compared with the prior art, the invention has the beneficial effects that:
1. after the method is implemented, the production progress of the original converter is not influenced.
2. The invention does not need to build a converter high-span factory building, thereby reducing one-time investment.
3. The invention is improved in the original factory building, and the new factory building is not built, thereby saving the construction period.

FIG. 1 is a floor plan of an embodiment of the present invention.
In the figure: 1-original auxiliary high-span column support, 2-new high-low-span column support, 3-newly-added frame column, 4-molten iron incoming material direction, 5-original converter station, 6-newly-added converter station, 7-stable column support, 8-original high span, 9-original auxiliary high span and 10-original low-span factory building position.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only illustrative and are not intended to limit the present invention.
The invention relates to a method for not stopping production of a newly-built converter station in a steel plant room without reserved stations, which increases the stations of a converter at the tail part of 4 in the molten iron feeding direction by utilizing the position of an auxiliary high span adjacent to the high span of the steel plant room.
The method specifically comprises the following steps:
1) a stable column support 7 is added at the original high span 8, so that the original high span 8 forms an independent stable system;
2) a new high-low span column support 2 is added at the tail part of the original auxiliary high span 9;
3) and cutting off the original auxiliary high-span column support 1, locally reforming the original auxiliary high span 9, and adding a frame at the position of the original auxiliary high span 9 to construct a converter platform.
According to the invention, through the analysis of the original workshop, the converter stations are increased at the tail part of the molten iron incoming direction by utilizing the adjacent auxiliary high span of the steelmaking workshop. The high span is formed into an independent stable system by adding the support, the auxiliary high span is locally improved, and a frame is added at the position of the auxiliary span to construct a converter platform. Because the station is added at the tail part of the incoming material and the high-span workshop forms a stable system, the original converter is not influenced by the reconstruction of the workshop to stop production, and the purpose of production conservation is achieved.
Example 1:
as shown in figure 1, two converter stations are arranged in an old factory building, and after the molten iron feeding direction 4 is determined, the newly added converter station 6 is arranged at the tail part of the feeding direction. The original auxiliary high-span column support 1 of the plant needs to be cut off, a new converter station 6 is vacated, before cutting off, a new high-low-span column support 2 is formed at the position 10 of the original low-span plant (the tail of the original auxiliary high-span 9), and the construction of a high-span newly-added stable column support 7 is completed at the position 8 of the original high span, so that the plant at the positions of the original two converter stations forms a stable system, and the production of the original converter station 5 is not influenced.
And constructing a newly-added frame column 3 in the position area of the original auxiliary high span 9 of the converter to form a supporting main steel frame of the high span operation platform of the converter, wherein the newly-added frame column 3 is constructed in a plant and is required to be constructed in sections from top to bottom, and the specific sections can be comprehensively determined according to the requirements of construction and plant height.
The invention has the advantages that the newly-built converter can be realized without stopping the production of the original converter, the position of the station of the newly-built converter determines the influence of the station on the production of the original converter, and the key point of the invention is to arrange the new converter at the tail part of the molten iron feeding direction and use the auxiliary high-span position of the original converter platform for construction, thereby avoiding the new high-span plant.
The steel-making converter platform has large load, an auxiliary span workshop without reserved converter stations cannot bear the load, and a frame is added at the position of the auxiliary span, so that the key for successfully building the converter platform is.
In order to not influence the original converter production, a stable column support 7 is added at a high-span factory building to ensure the independent stability.
