Description
Technical field
The utility model relates to steelmaking equipment technical fields, more particularly to a kind of inserted safe converter bottom structure.
Background technique
Existing converter bottom is big furnace bottom, and furnace bottom seam is difficult to handle when closing furnace bottom, and there are larger for body brick and bottom brick
Gap, can only be made up by clogging resistance to material, cause furnace bottom to seep steel serious, brought to furnace body safe operation greatly hidden
Suffer from.In addition, furnace bottom and furnace body are not easy to combine, also once there were the accident that furnace bottom falls off in production process in other steel mills.Big furnace bottom is unfavorable
It is safeguarded in furnace body, is unfavorable for shop safety production, there are biggish hidden danger, big bottom construction figure such as Fig. 1.
Utility model content
The utility model in order to make up for the deficiencies of the prior art, provides a kind of inserted safe converter bottom structure, solution
It has determined problems of the prior art.
The utility model is achieved by the following technical solution:
A kind of inserted safe converter bottom structure is equipped with a circular open in furnace shell center bottom, sets on the inside of furnace shell
There is furnace lining, the furnace lining is built by shaft brick along furnace shell circumferential direction, the bottom face and furnace shell bottom end inner sidewall of shaft brick
Fitting；A small furnace bottom is equipped with below furnace shell, small furnace bottom matches with the circular open of furnace shell center bottom, the small furnace bottom by
Furnace bottom brick masonry forms, and bottom brick top, which is protruded into molten bath, to be arranged；Bonding makes material firm by ramming between small furnace bottom and furnace lining junction；?
It is fixed with a Bottom Blowing Ejection Gun through flangeseal on small furnace bottom, Bottom Blowing Ejection Gun top is pierced by small furnace bottom top setting, bottom blowing spray
Rifle bottom end is pierced by small furnace bottom and is connected with external Bottom Blowing source.
The small furnace bottom and furnace shell use screw bolt reinforcing, and bolt penetrates shaft brick bottom by furnace shell bottom end and is arranged.
The small furnace bottom includes bottom brick and the supporting steel plate set on bottom brick bottom end, and shaft brick and supporting steel plate are connected,
Bottom brick and furnace shell pass through the screw bolt reinforcing across supporting steel plate and shaft brick.
Bottom brick height is at least 5 layers of shaft brick height.
The utility model has the beneficial effects that
The inserted safe converter bottom structure optimization masonry way and structure are convenient for masonry of well using small furnace bottom,
The block furnace time has been saved, has reduced furnace bottom and seeps steel, eliminate security risk, improve furnace bottom safety coefficient, has improved smelting effect
Rate；The inserted safe converter bottom structure fastens furnace bottom and furnace body combination more, not easily to fall off.
Detailed description of the invention
Fig. 1 is existing big bottom construction schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model.
In figure, 1 furnace shell, 2 furnace linings, 3 supporting steel plates, 4 small furnace bottoms, 5 molten baths, 6 make material, 7 Bottom Blowing Ejection Guns, 8 bolts firm by ramming.
Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
If Fig. 1 is existing big bottom construction schematic diagram, the junction between furnace bottom and shaft is fixed for flat contact, closes furnace
Furnace bottom seam is difficult to handle when bottom, and there are biggish gaps for body brick and bottom brick, can only be made up, be made by clogging resistance to material
It is serious at furnace bottom infiltration steel, great hidden danger is brought to furnace body safe operation.
As shown in Fig. 2, the inserted safe converter bottom structure is small furnace bottom design structure, furnace shell 1 is specifically included, in furnace
Shell center bottom is equipped with a circular open, and furnace lining 2 is equipped on the inside of furnace shell, and the furnace lining is built by shaft brick along furnace shell circumferential direction
It builds, the bottom end of the shaft brick is bonded with furnace shell bottom end inner sidewall；It is equipped with one below furnace shell 1 and is equipped with one below furnace shell
Small furnace bottom 4, small furnace bottom 4 are matched with the circular open of furnace shell center bottom, and the small furnace bottom 4 is formed by furnace bottom brick masonry, furnace
Bottom brick top, which is protruded into molten bath, to be arranged；Bonding makes material 6 firm by ramming between 2 junction of small furnace bottom 4 and furnace lining；Through method on small furnace bottom 4
Blue disk sealing is fixed with a Bottom Blowing Ejection Gun 7, and 7 top of Bottom Blowing Ejection Gun is pierced by small furnace bottom top setting, and Bottom Blowing Ejection Gun bottom end is pierced by
Small furnace bottom is simultaneously connected with external Bottom Blowing source.
The small furnace bottom 4 is reinforced with furnace shell using bolt 8, and bolt penetrates shaft brick bottom by furnace shell bottom end and is arranged.
The small furnace bottom 4 includes bottom brick and the supporting steel plate 3 set on bottom brick bottom end, and shaft brick and supporting steel plate 3 are solid
Even, bottom brick and furnace shell are passed through reinforces across the bolt 8 of supporting steel plate and shaft brick.
Bottom brick height is at least 5 layers of shaft brick height.
The furnace shell bottom of the inserted safe converter bottom structure first builds shaft brick along furnace shell, the furnace after finishing building shaft brick
Shell is the open structure of center bottom；Build bottom brick obtain small furnace bottom, or on supporting steel plate build bottom brick formed it is small
Small furnace bottom is transported to below furnace shell by furnace bottom, by small furnace bottom it is vertical on move to and cooperate at the circular open of furnace shell center bottom,
The junction filling of small furnace bottom and furnace lining, furnace shell makes material firm by ramming, carries out ramming using tamping tool, makes material firm by ramming and hit by tamping tool
