Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a ground vehicle arrangement system for an RH refining system. Background Art

[0002] Liquid steel circulation degassing (RH) is a molten steel refining process. Its principle is to use the pressure difference to make the liquid steel enter the vacuum degassing chamber from the circulation pipe, and at the same time blow the driving gas from one of the two circulation pipes (the riser), and use the bubble pump principle to draw the liquid steel through the degassing chamber and the downcomer to produce a circular motion, and remove the gas (N2, H2, O2) in the vacuum chamber. In order to improve production efficiency, most modern RH vacuum refining equipment adopts a double-station layout. The vacuum system is arranged on the upper floor, and two sets of ladle car systems are arranged parallel to the ground. After the vacuum treatment of one station is completed, the station is switched through the vacuum system, and the other station can be processed immediately. Compared with the single-station layout, it saves the preparation time of one station. When one station is vacuum-treated, the other station has sufficient time to use the nozzle maintenance vehicle to perform top slag treatment and spray repair maintenance of the immersion tube. The nozzle maintenance vehicle needs to move continuously between the processing position and the standby position.

[0003] At present, the demand for RH refining is gradually increasing. The existing steel mills are basically mature, with compact overall layout and small remaining space. It is difficult to build a new RH refining project in the existing workshop, and the issue of space occupancy needs to be considered.

[0004] The ground vehicle arrangement of the existing RH refining system mainly includes a nozzle maintenance vehicle system 5 and a ladle car system 1, wherein the nozzle maintenance vehicle mainly includes two parts: a slag removal device 23 and a gunning device 33, which respectively perform slag removal and gunning maintenance of the nozzle. At present, there are two schemes for the arrangement of the nozzle maintenance vehicle. The prior art is that one nozzle maintenance vehicle system 5 is arranged on each of the two ladle car tracks 11 (as shown in the attached figure). Figure 2 ), each nozzle maintenance vehicle system 5 corresponds to a workstation, and they do not interfere with each other; the prior art is that the maintenance vehicle track 51 is perpendicular to the ladle vehicle track 11, and two nozzle maintenance vehicles are arranged on the maintenance vehicle track 51, and the top slag treatment and spray repair maintenance of the nozzles of the two workstations are realized by the transverse movement of the vehicles (such as the attached Figure 3 ).

[0005] The slag-removing device 23 and the spraying device 33 are concentrated on the nozzle maintenance vehicle, which prolongs the overall length of the vehicle, whether it is arranged on the same rail as the ladle car (such as the attached Figure 2 ) or vertical arrangement (such as attached Figure 3 ), all of which increase the floor space of the entire system and even require the expansion of the upper platform area, increasing investment costs.

[0006] Therefore, the inventor, relying on his many years of experience and practice in related industries, proposes a ground vehicle arrangement system for a RH refining system to overcome the defects of the prior art. Utility Model Content
