Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] like figure 1 and figure 2 As shown, the device for replacing the furnace mouth of the converter of the present invention includes a column 1 and a movable table 2. There are four columns 1, and the top of the column 1 is connected by a platform beam 3 and a platform cover is provided. A working beam 4 and a rotating beam 5 are arranged between the columns 1 below the platform cover. The working beam 4 and the rotating beam 5 are parallel to each other and are respectively arranged on different columns 1. The two ends of the rotating beam 5 are installed on the columns through bearings 6. 1, so the rotating beam 5 can be rotated, and the two ends of the working beam 4 are fixedly installed on the column 1.
[0032] The upper surfaces of the working beam 4 and the rotating beam 5 are located on the same horizontal plane and form a gap with the lower surface of...

The invention discloses a device and a method for replacing a converter mouth, and relates to the technical field of converter steelmaking in metallurgical industry, which solves the problems of waste of time and labor, long construction cycle and low safety in the temporary built overhauling platform. By adopting the technical scheme, the device for replacing the converter mouth comprises vertical columns and a movable worktable, wherein the top ends of the vertical columns are connected by a platform transverse beam, and a platform cover plate is arranged on the vertical columns; a working transverse beam and a rotary transverse beam are arranged between the vertical columns under the platform cover plate; the movable worktable is arranged on the working transverse beam and the rotary transverse beam, and can be extended or retracted; a counterweight for balancing the worktable is arranged on the platform transverse beam, away from one side of the rotary transverse beam, at the top end of each vertical column, a tool kit is arranged on the platform beam, close to the rotary beam, at the top of each vertical column. According to the device and the method for replacing the converter mouth, the extending length and direction of the movable worktable can be flexibly adjusted, the tilting angle of the converter is adjusted, the auxiliary material carrying time of an operator is shortened, and the quick and safe operation effect is realized.
Description
technical field [0001] The invention relates to the technical field of converter steelmaking in the metallurgical industry, in particular to a device and method for replacing a converter mouth. Background technique [0002] Oxygen top-blown converters are commonly used in the metallurgical industry for steelmaking production. The furnace mouth is an important device for protecting and protecting the refractory layer. It can reduce the adhesion of steel slag on the sub-furnace mouth, strengthen the furnace mouth rigidity, reduce the deformation of the furnace mouth, and improve the stress state. , to prolong the life of the furnace cap and furnace lining. [0003] At present, the water-cooled furnace mouth is generally used. The water-cooled furnace mouth is located in the upper part of the furnace body, and the temperature is above 1600 ° C. The inside of the furnace mouth is cooled by circulating water, and the cooling water pressure (inlet) is 0.4 ~ 0.6MPa. The mouth is p...
