Abstract
The utility model discloses a melting furnace metal export and clearance structure thereof, including resistant firebrick, it has the metal export to open in resistant firebrick to and the wooden plug, its characterized in that: the metal export includes funnel shape hole and round hole, the major diameter end in funnel shape hole is located resistant firebrick one side outer wall, and the minor diameter end in funnel shape hole is located resistant firebrick, the inner in round hole links to each other with the minor diameter end in funnel shape hole, and the outer end of round hole is located resistant firebrick opposite side outer wall, the outer end of round hole is equipped with the chamfer, cork and round hole interference fit. The utility model has the beneficial effects that the continuous metal melting furnace can be used safely and long-term and maintained conveniently when metal liquid is put into the ladle process.
Description
Technical field
The utility model relates to casting technology field, specifically a kind of melting furnace metal outlet and cleaning structure thereof.
Background technology
At present, using the foundry of continous way metal molten stove (such as: furnace cupola, natural gasification aluminium stove etc.), when storage deposite metal forehearth interior metal liquid is to time a certain amount of, will carry out putting the operation of metal liquid to casting ladle.
Metal outlet repairing and use are a very meticulous job, in metal fusion process, often metal molten stove can be caused normally not dissolve because metal outlet breaks down.Easily there is following problem under normal circumstances:
1, most of foundry adopts two kinds of methods when repairing metal outlet: one is repair metal outlet with fire clay, and two is repair metal outlet with indefinite form material (refractory cement).First method flows out about 30t when metal liquid, has just brushed metal outlet bad.Second method is merely able to single use, again repairs and is not suitable for because baking time needs a couple of days to produce.
2, each continous way metal molten stove dissolves after task completes, and residual metal and slag stick in metal outlet inside, and when again repairing, metal outlet cleans out metal and slag just easily damages.
Once occur that metal outlet damages in fusion process, work of dissolving just is difficult to carry out.
Utility model content
The purpose of this utility model is the deficiency existed to solve above-mentioned background technology, proposes a kind ofly can to use and melting furnace metal outlet easy to maintenance and cleaning structure thereof by safety and effectivity to watering in packet procedures carrying out putting metal liquid at continous way metal molten stove.
In order to realize above object, a kind of melting furnace metal outlet that the utility model provides and cleaning structure thereof, comprise refractory brick, metal outlet is had in described refractory brick, and stopper, it is characterized in that: described metal outlet comprises funnel-shaped hole and circular hole, the larger diameter end of described funnel-shaped hole is positioned on the outer wall of refractory brick side, the smaller diameter end of funnel-shaped hole is positioned at refractory brick, the inner of described circular hole is connected with the smaller diameter end of funnel-shaped hole, the outer end of circular hole is positioned on refractory brick opposite side outer wall, the outer end of described circular hole is provided with chamfering, described stopper and circular hole interference fit.
As preferred version of the present utility model, the length of described stopper is not less than the length of circular hole.
Further, described refractory brick is prepared from by clay material.
The same day dissolve after task completes, entered by stopper in metal outlet, residual metal and slag can be extruded metal outlet by stopper, are cleaned out by the stopper carbonized when within second day, forehearth is repaired in metal outlet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
In figure: refractory brick 1, metal outlet 2, funnel-shaped hole 2.1, circular hole 2.2, hypotenuse 3, stopper 4.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: as Fig. 1, a kind of melting furnace metal outlet shown in Fig. 2 and cleaning structure thereof, comprise the refractory brick 1 be prepared from by clay material, metal outlet 2 is had in described refractory brick 1, and stopper 4, it is characterized in that: described metal outlet 2 comprises funnel-shaped hole 2.1 and circular hole 2.2, the larger diameter end of described funnel-shaped hole 2.1 is positioned on the outer wall of refractory brick 1 side, the smaller diameter end of funnel-shaped hole 2.1 is positioned at refractory brick 1, the inner of described circular hole 2.2 is connected with the smaller diameter end of funnel-shaped hole 2.1, the outer end of circular hole 2.2 is positioned on refractory brick 1 opposite side outer wall, the outer end of described circular hole 2.2 is provided with chamfering 3, described stopper 4 and circular hole 2.2 interference fit.The length of described stopper 4 is not less than the length of circular hole 2.2.
When smelter according to normal repair forehearth time refractory brick 1 is installed to the position of needs, because refractory brick 1 does not prefabricatedly in advance worry that metal outlet 2 is containing the not dry situation of moisture baking, other repairing and baking are with identical in the past.The same day dissolve after task completes, filled in by stopper 4 in metal outlet 2, residual metal and slag can be extruded metal outlet 2 by stopper 4.Meanwhile, due to metal outlet extreme temperatures, stopper 4 can be carbonized, and is cleaned out by the stopper 4 carbonized when within second day, forehearth is repaired in metal outlet.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
