Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further details:
The present invention is a kind of casting system for the casting of big specification cast steel roll, by sprue and cross gate junction
Build resistance to material by laying bricks or stones and carry out rational structure design, prevent stuffing sand sintering blocking running gate system.Use the casting system of the present invention, can
So that molten steel need not be put outward, it is greatly saved casting cost.
As Figure 1-3, casting system of the present invention includes cup 5, sprue 6, cross gate 7, and cup 5 end opening connects
Sprue 6 is suitable for reading, and sprue 6 end opening connects cross gate 7, and described cup 5, sprue 6, cross gate 7 are by outer wall and inwall 9
Composition, wherein inwall 9 is formed by casting laying fireproof bricks, is positioned at the refractory brick of sprue 6 and cross gate 7 seam for directly to water
Road nest special form brick and connection special form brick, sprue base special form brick includes brick body and the sprue base 4 being positioned on brick body, directly
Running channel nest import is positioned at brick body upper surface；Connect special form brick and include brick body and the casting runner through brick body, casting
Tunnel inlets 1 is positioned at brick body upper surface, and casting runner exit 2 is positioned at brick body side end face, with casting tunnel inlets position phase
To brick body on be communicated with the sprue channel open 3 of sprue base.When building by laying bricks or stones, sprue base special form brick is positioned under connection special form brick
Side, sprue base import alignment sprue channel open 3, see Fig. 4.During use, above cup 5, prevent sand block cap 8, refining ladle water
Mouth, just to sand block cap, pulls open the mouth of a river, and powder stuffing sand is stopped by sand block cap, and sand block cap is burnt by follow-up molten steel, enters cast
System, if there being sintering stuffing sand to enter running gate system, stuffing sand will be stored by sprue base, will not block running gate system.
During in order to ensure casting, molten steel does not produce eddy flow or turbulent flow in casting system, connects the casting on special form brick
Runner is pass casting runner, and uniform pore diameter is consistent.
In order to ensure that sprue base can play the effect of storage sintering stuffing sand conscientiously, and do not affect entering of casting
OK, 1.5 times of described sprue channel open 3 a diameter of casting flow diameter；Described sprue base 4 is by one section of circular hole and one and half ball groups
Becoming, circular hole is positioned at upper end；Described Circularhole diameter is 1.5 times of casting flow diameter, and half ball sphere diameter is casting flow diameter
1.5 again.The overall sprue base degree of depth that sprue base special form brick and connection special form brick are formed after assembling is by circular hole portion and half ball
Duan Zucheng, the circular hole portion degree of depth is the 1/2 of casting flow diameter, and sprue base total depth is 1.25 times of casting flow diameter.
As in Figure 2-4, during in order to ensure to build by laying bricks or stones, the gap between refractory brick is easily controlled, and meets the stream of molten steel
To, even if refractory brick does not lay, there is gap between refractory brick, be also not easy seepage, at casting tunnel inlets 1, arrange one
Section taper hole, aperture, taper hole upper end is more than casting flow passage aperture；Brick body at casting runner exit 2 is one section of cone, and cone
Path one side end face be brick body side end face；Arranging one section of taper hole at sprue channel open 3, aperture, taper hole lower end is more than casting runner hole
Footpath；The brick body of sprue base 4 import department is one section of cone, and path one side end face of cone is brick body upper surface.
