Description
Technical field
It is espespecially a kind of to reduce plate temperature the utility model relates to inhale the water-cooled plate structure of casting device in a kind of negative pressure
Degree, and can effectively extend plate service life, and ensure the sealing effect person between cover and plate.
Background technique
The gravity-assist pouring method of traditional steel casting factory, mainly with calciner by steel melt to 1450~1700 DEG C it
Afterwards, the molten steel of high temperature is contained in metal bucket, then molten steel is toppled in the mold for being cast in pre-production, allow molten steel by gravity
Effect, pours pond, sprue and runner by flow path system, and by being flowed into die cavity into Tang Kou, after molten steel cooled and solidified certainly
It is taken out in mold, through cleaning appropriate and processing, to obtain required casting.
Above-mentioned gravity-assist pouring method mostly uses the casting in steel MTR.However, examining based on casting cost and casting quality
Amount, the utility model designer, which proposes, inhales pouring procedure in a kind of negative pressure, including the following steps:
A. by the flat plate cover with suction pipe together in the top of calciner, the molten steel of melting, and suction pipe are loaded in calciner
Bottom end protrude into molten steel；B. the air duct of connection die cavity is formed on mold, and mold is placed on plate, makes mold
Flow path system be connected to the top of suction pipe；C., one cover is covered on to the top of mold and plate, and extracts the intracorporal sky of cover
Gas makes the decrease in air pressure in cover and die cavity, is drawn up the molten steel in calciner via suction pipe, and molten steel is made to flow into die cavity
It is interior；And d. stands a period of time, allows solidifying between flow path system and die cavity into soup mouth, then the intracorporal air negative pressure of release cover
State reversely flows back towards the molten steel in flow path system in calciner.
Utility model content
By pouring procedure is inhaled in above-mentioned negative pressure, cost can be effectively saved really, and improves the thin and complex product of meat
Casting shaping efficiency.However, in actual use, since flat plate cover is together in the top of calciner, high-temperature fusion steel in calciner
The phenomenon that radiant heat that liquid is distributed can allow plate to be easy to produce bending deformation, and make the sealing effect between cover and plate
It reduces, influences the formation of negative pressure.It therefore, generally all can be in plate in order to reduce the speed of plate deformation to prolong the service life
Lower section installation have suitable thickness refractory cotton, with obstruct molten steel rising hot gas.But since the thickness of refractory cotton is too thick,
Opposite will reduce the molten steel capacity that can be contained in calciner, and the frequency for causing molten steel to supplement increases and reduces production effect
Rate.In view of this, in order to provide a kind of structure for being different from the prior art, and improve above-mentioned disadvantage, utility model designer
The experience of product many years and continuous research and development improve, and have the generation of the utility model then.
One purpose of the utility model provide it is a kind of inside plate equipped with horizontal buckling shape cold water pipe water cooling it is hardened

System；Top of one flat plate cover with suction pipe together in a pouring furnace；Mold is placed on plate, has connection die cavity on mold
One air duct, the flow path system of mold are connected to the top of suction pipe；The top lid of mold and plate unifies cover, cover connection
One air extractor covers intracorporal air for extracting.Its main technical characterstic is: water-cooled plate structure includes above-mentioned plate and one
There is a top surface and a bottom surface, cold water pipe to be folded between top surface and bottom surface with horizontal buckling shape for cold water pipe, plate, cold water pipe tool
There are interconnected water inlet end and water outlet, and water inlet end and water outlet are located at the outside of plate, for conveying circulating water flow to drop
The temperature of low plate.
When implementation, the utility model further includes a top plate, and the top face for being positioned at plate is laminated in top plate, and top plate has
Upper and lower perforative through-hole, through-hole are connected to up and down with the top of suction pipe.
The utility model has the advantage that
1, the utility model is evenly distributed on inside plate with cold water pipe, therefore, can be when conveying circulating water flow, effectively
The temperature for reducing plate prevents plate because of heated the phenomenon that generating bending deformation, and then extends plate service life, and ensure cover
Sealing effect between body and plate.
2, the temperature of plate can be effectively reduced in the utility model, and therefore, the refractory cotton that can be greatly decreased below plate is thick
Degree, and then increase the molten steel capacity that can be contained in calciner, to improve production efficiency.
3, the top face that top plate stacking is positioned at plate is not necessarily to by the utility model system in top plate bending deformation
Plate and cold water pipe are replaced, and is only therefore direct replacement top plate can reduce manpower maintenance activity cost.
