Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, the invention will be further described.
A kind of without mould steel ball casting device, including holding furnace 10, the lower section of holding furnace 10 be provided with by
Upper and under the first disk the 20th, rotating disk 30 and the second disk 40 that are sequentially arranged, also include locating shaft
50, locating shaft 50 after the center of the first disk the 20th, rotating disk 30 and the second disk 40 passes through by three
Person is fixed on the lower section of holding furnace 10, for being rotatably assorted between rotating disk 30 and locating shaft 50, and first
The first circular hole 21 and the second circular hole 41, rotating disk 30 is offered respectively on disk 20 and the second disk 40
On offer the 3rd circular hole 31, the 3rd circular hole 31 is two or more and along between the edge circumference of rotating disk 30
Every arrangement, the aperture of the first circular hole the 21st, the second circular hole 41 is more than the aperture of the 3rd circular hole 31, the
Distance between center line locating shaft 50 center line of one circular hole the 21st, the second circular hole 41 and the 3rd circular hole 31
Apart from identical, the lower end outlet 11 of holding furnace 10 is just to the first circular hole 21, under the second disk 40
Side arranges straight tube 60, and straight tube 60 vertical and the upper end mouth of pipe are just to the second circular hole 41, straight tube 60
The lower end mouth of pipe at arrange steel ball roller track 70, at the bottom tube wall of described straight tube 60 arrange steam
The entrance 80 of vapour, entrance 80 connects with high steam device, and the steam of high steam device output is certainly
Entrance 80 rear bottom-up injection in entering straight tube 60.
When the present invention uses, first molten steel is poured in holding furnace 10, the lower end of molten steel self-heat conserving stove 10
Entering into after outlet 11 outflow in the first circular hole 21 of the first disk 20, rotating disk 30 turns to the 3rd
Circular hole 31 and the first circular hole 21 just pair when, molten steel falls in the 3rd circular hole 31 from the first circular hole 21,
At this moment molten steel is followed rotating disk 30 in the 3rd circular hole 31 and is rotated together, when the 3rd circular hole 31 and second
Circular hole 41 just pair when, molten steel will enter in the second circular hole 41 from the 3rd circular hole 31, then fall
Fall in straight tube 60, straight tube 60 is connected with high steam and sprays from bottom to top, can slow down under molten steel
Terminal-velocity degree, molten steel fall in straight tube 60 during because of its own face tension force effect self-assembling formation
Spherical shape cooled and solidified become steel ball, and steel ball rolls out along roller track 70 in falling into engine oil drum and turns blue
Processing and being collected, whole steel ball casting process completes.Wherein, rotating disk 30 thickness and
The pore size of the 3rd circular hole 31 directly determines the diameter of steel ball the work playing decile molten steel
With；The aperture of the first circular hole 21 and the second circular hole 41 is slightly larger than the 3rd circular hole 31 aperture in order to steel
Liquid is split and falls.Whole apparatus structure is simple, and the steel ball metallographic structure processing is complete, steel ball matter
