Abstract
The utility model discloses a flow stabilizing block for casting and pouring a fired mould. Key technology is that the flow stabilizing block is shaped like a circular truncated cone, wherein shape of a conical surface of the flow stabilizing block is matched with that of the inner surface of a pouring cup of the cast mould shell; and an inclined sprue is arranged on the flow stabilizing block. The flow stabilizing block disclosed by the utility model has a simple structure, directly adopts the existing material, and is simple and convenient to manufacture, and convenient to apply; before pouring, the flow stabilizing block is placed into the pouring cup of the mould shell for pouring, molten steel flows down from the sprue in an inclined manner, flushes to the side wall of the pouring cup, and flows into a mould cavity along the side wall of the pouring cup, so that flow stabilizing effect is achieved. The flow stabilizing block disclosed by the utility model can be repeatedly applied for pouring a plurality of mould shells, so that defects of surface gas pits and slag gas pits of a casting piece are effectively avoided, surface quality of the casting piece is improved, sharpening-welding recharge is lowered, and rejection rate is lowered.
Description
Technical field
The utility model relates to a kind of model casting cast current stabilization piece.
Background technology
During model casting smelting and pouring, generally all adopting steel fork that shell is delivered to fire door directly pours into a mould, because liquid stream size is by Artificial Control, easily there is molten steel turbulent flow phenomenon, cause molten steel volume gas, there is the defects such as air pit, slag air pit in cast(ing) surface, has a strong impact on casting quality, cause soldering reconditioning quality to increase, when serious, cause foundry goods to scrap.Avoiding rolling up the method that gas is conventional is to reduce poring rate, or inclination shell rushes to cup inwall molten steel, along tangent line, flows into running channel, poring rate reduction easily causes foundry goods cold shut and misrun defect, during inclination shell, workman operation is more difficult, is difficult for grasping unstable product quality.
Therefore in the urgent need to a kind of novel technology, can effectively improve the quality of product.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, make easy to use, steady flow result good and can improve the model casting cast current stabilization piece of casting quality.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of model casting cast current stabilization piece, its key technology is: the block-shaped circular cone bench-type that is of described current stabilization, the conical surface shape of this current stabilization piece matches with the cup inner surface of the shell that waters, and described current stabilization piece is provided with the running channel of inclination.
The entrance of described running channel is positioned at the upper surface home position of current stabilization piece, and the outlet of described running channel is positioned at current stabilization piece lower surface edge position.
Described current stabilization piece Facing material is Ludox zirconium powder slurry and zircon sand, and inner materials is that zirconium powder, corundum mix slurry and emergy.
Described current stabilization piece is pancake shape.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, it directly uses current material, make simple and convenient, easy to use, before cast, current stabilization piece being put into shell cup place pours into a mould, molten steel flows down and is flushed to cup sidewall from running channel inclination, along cup sidewall, flows in die cavity, reaches steady flow result.A plurality of shells of this novel reusable cast, have effectively avoided cast(ing) surface air pit, slag air pit defect, improve surface quality of continuous castings, reduce reconditioning soldering amount, the rate of reducing the number of rejects and seconds.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this novel cross-sectional schematic;
Fig. 3 is this novel use schematic diagram;
Wherein, 1, current stabilization piece; 2, cup; 3, running channel; 4, the conical surface.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, this current stabilization piece 1 shape is circular cone bench-type, is pancake shape in short transverse, and the conical surface 4 shapes of this current stabilization piece match with cup 2 inner surfaces of the shell that waters, and described current stabilization piece 1 is provided with the running channel 3 of inclination.The entrance of described running channel 3 is positioned at the upper surface home position of current stabilization piece 1, and the outlet of described running channel 3 is positioned at current stabilization piece 1 lower surface edge position.
The preparation method of this current stabilization piece is as follows: with current stabilization piece Mold Making wax-pattern die cavity, be coated with refractory material in die cavity, surface layer is used Ludox zirconium powder slurry, spreads 120 order zircon sands, and all the other levels are used zirconium powder, corundum to mix slurry, spread 120 order emergies.Alternately stucco is dry, until die cavity fills up, after dewaxing, upper plane is polished with abrasive band.Alternately be coated with, stucco will guarantee that every layer is coated with closely, thoroughly dry, prevents said minuscule hole, to guarantee the intensity of current stabilization piece, impacts cracked while avoiding pouring into a mould.
Referring to accompanying drawing 3, using method of the present utility model is as follows: before use, with the shell that will pour into a mould, together enter roaster roasting, before cast, current stabilization piece 1 is put in the cup 2 of watered shell and poured into a mould, molten steel flows down and is flushed to cup 2 sidewalls from running channel 3, along cup 2 sidewalls, flow in die cavity, reach steady flow result.Pour after a shell, current stabilization piece 1 is chosen from cup 2, can use continuously.
The utility model is used high-temperature refractory to make, and refractoriness is high, can effectively avoid molten steel volume gas, improves surface quality of continuous castings, and it adopts full form casting process, make simple and convenient, any surface finish.
