Abstract
A kind of air-cooled iron for casting, including chill body are the utility model is related to, it is characterized in that：Air channel is provided with the chill body, the upper surface of chill body is provided with air inlet and air outlet.The time for being passed through cold wind increase iron chill shock chilling effect spends in the air-cooled Tie Tong for casting, can either accelerate the heat transfer speed of chill, also greatly increases the heat storage capacity of chill, so as to effectively eliminate shrinkage porosite, reduces casting wasted product rate.
Description
Technical field
It the utility model is related to a kind of chill, especially a kind of air-cooled iron for casting.
Background technology
Wind energy is increasingly paid attention to by countries in the world as a kind of regenerative resource of cleaning, and the casting of big MW series
Part requires also more and more stricter.Base is as the important spare part in unit, and performance requirement is especially high, especially casting punching position
Put, it is desirable to which higher, shrinkage porosite can not appear, if finding that misrun casting will then be scrapped, loss is too big, solves the problems, such as the shrinkage porosite of casting
Become an important ring for casting industry.To eliminate Shrinkage Porosity defect, inside die cavity, mold cavity surface and casting mold placed inside
The a kind of of routine solves the problems, such as the mode of shrinkage porosite when chill is existing production, and it is that Quench, tradition are carried out to casting that chill acts in itself
Chill form may can reduce to the chilling action in later stage, such as use graphite chilling block, heat transfer speed is fast, but the storage of itself
Heat energy power is small, that is to say, that graphite chilling block can allow casting is local quickly to cool down, when casting temperature is also without reducing too many
Wait, graphite chilling block is just " having enough ", it is impossible to absorbs heat again, therefore can not effectively solve the problems, such as Shrinkage Porosity.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of air-cooled iron for casting,
The time for increasing iron chill shock chilling by being passed through cold wind and acting on, the heat transfer speed of chill can either be accelerated, also greatly increase chill
Heat storage capacity, so as to effectively eliminate shrinkage porosite, reduce casting wasted product rate.
According to technical scheme provided by the utility model, the air-cooled iron for casting, including chill body, its feature
It is：Air channel is provided with the chill body, the upper surface of chill body is provided with air inlet and air outlet.
Further, the one side of the chill body or two sides are provided with raised hanging sand structure.
Further, the hanging sand structure is symmetrical set.
Further, the chill body is welded by steel plate.
Air-cooled iron described in the utility model for casting is placed in casting suitable position, can improve Feeding channel, is improved
Internal Quality of Cast grade, there is provided premium casting；Coordinate the circulation of cold wind to extend the chilling action of chill, accelerate the solidifying of casting
Gu speed, crystal grain thinning tissue, improve the mechanical property of casting.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is utility model works view.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2：The air-cooled iron for casting include chill body 1, air channel 2, air inlet 3, air outlet 4,
Hanging sand structure 5 etc..
As shown in Figure 1, 2, the utility model includes chill body 1, and air channel 2, chill body are provided with the chill body 1
1 upper surface is provided with air inlet 3 and air outlet 4, and the one side of the chill body 1 or two sides are provided with raised hanging sand structure
5, hanging sand structure 5 is symmetrical set；The chill body 1 is welded by steel plate.
Operation principle and the course of work of the present utility model：The air-cooled iron for casting mainly by steel plate weld and
Into, it is desirable to can not there are gap, welding to do infiltration test after terminating.As shown in figure 3, the working surface polishing light by air-cooled iron
It is sliding, and molding sand is embedded in by the hanging sand structure 5 of projection, it is allowed to fixed, prevents air-cooled iron from being sunk in top box face, be then placed within
Casting punch position；Cold wind is passed through from the air inlet 3 of air-cooled iron, cold wind is flowed through behind air channel 2 from the row of air outlet 4 during pouring molten iron
Go out.
Operation principle is aweather to be passed through cold wind in chill, and cold wind takes away the heat that air-cooled iron is absorbed, and reduces air-cooled iron table
Face temperature, extend chill time of the air-cooled iron to casting, so as to more effectively to Local cooling, reach the purpose of consecutive solidification.
