Specific embodiment
As shown in Figures 2 and 3, the sector with fan-shaped slag trap of the invention includes：Fan section and area 9 of slagging tap, go out
Upper end of the slag area 9 in fan section, it is characterised in that：In fan section by the straight baffle plate 8, triangle of the cast gate circular arc 3, triangle being sequentially connected
Bottom baffle 7, bag bottom baffle 6 and fan shape baffle 5 are constituted, and slag trap 1 is also equipped with fan section, and cast gate circular arc 3 is wrapped with sector
Pivot 4 is the circular arc to the direction of area 9 projection of slagging tap in the center of circle, and slag trap 1 and fan shape baffle 5 are with sector bag rotation
The heart 4 is the circular arc in the center of circle, and the circular arc of fan shape baffle 5 accounts for 40 °~70 ° that it justify on a radius of circular arc, and slag trap 1 arrives fan-shaped
The radius of bag pivot 4 is the 1/5~1/3 of the radius that fan shape baffle 5 arrives fan-shaped bag pivot 4, the circular arc of slag trap 1 with
The angle of fan-shaped bag pivot 4 is more than the circular arc of fan shape baffle 5 and the angle of fan-shaped bag pivot 4.Slag trap 1 is in triangle
In the fan section of the top of bottom baffle 7, the bottom of slag trap 1 is identical away from the distance between triangle bottom baffle 7.Slag trap 1 is by fire resisting
Material is made.
Fan-shaped bag pivot 4 is located at the lower section of area 9 of slagging tap, and the radius of cast gate circular arc 3 is less than the height in area 9 of slagging tap.Bag bottom
Baffle plate 6 is connection fan shape baffle 5 and the tangent straight line of cast gate circular arc 3.The straight baffle plate 8 of triangle is tangent with the circular arc of cast gate circular arc 3
Vertical line.Triangle bottom baffle 7 is the straight line for connecting the straight baffle plate 8 of triangle and bag bottom baffle 6, between the straight line and horizontal line
Angle is -6 °~-15 °.The straight baffle plate 8 of cast gate circular arc 3, triangle, triangle bottom baffle 7, bag bottom baffle 6 and fan-shaped gear in fan section
Plate 5 is built with flame retardant coating 2.
It is of the invention fan-shaped compared with existing fan-shaped bag with fan-shaped slag trap, due to slag trap 1, fan shape baffle 5
And cast gate circular arc 3 is concentric circles, fan-shaped bag pivot 4 is simultaneously actual pivot of the fan-shaped bag in casting process.Fan
The bag bottom baffle 6 of shape bag makes the shape shown in Fig. 2.Fan-shaped slag trap 1 is added in the inside in fan section.Iron liquid is from slag trap
Flowed out between 1 and triangle bottom baffle 7.The sectional area of the distance between slag trap 1 and triangle bottom baffle 7 composition is greater than fan-shaped bag
The sectional area of cast gate.Following beneficial effect can be produced after the change shown in Fig. 2 is made to sector bag：
1st, the fan-shaped bag pivot 4 of fan-shaped bag is simultaneously the circle of slag trap 1, fan shape baffle 5 and cast gate circular arc 3 in Fig. 2
The heart, the iron liquid of outflow is equivalent in any unit interval when so can ensure that constant angular velocity turns over bag.
2nd, the outflow mode of iron liquid is changed into by original successively outflow from top to bottom and flowed out from the middle of fan-shaped bag, so
Outflow mode allow light impurities thing in iron liquid to there is the sufficient time to float, the impurity thing after having floated can not possibly be with iron
Liquid flows out again, so that the iron liquid of the fan-shaped bag of outflow is purified, reduces the casting flaw probability that clinker is caused.
3rd, slag trap 1 gos deep into the place plane of bag bottom baffle 6, it is ensured that remain iron liquid as far as possible in fan-shaped bag after casting complete
It is few.
4th, slag trap 1 gos deep into the place plane of bag bottom baffle 6, prevents scum silica frost from being wrapped with the iron liquid outflow sector in cast latter stage.
5th, triangle bottom baffle 7 is designed to inclined-plane rather than horizontal plane, it is ensured that after fan-shaped bag casting complete, residual it is a small amount of
Iron liquid and the scum silica frost for being kept off can smoothly return to bag bottom along the inclined-plane of triangle bottom baffle 7, not result in blocking.
6th, slag trap 1 is greater than the sectional area of fan-shaped bag cast gate with the sectional area in the gap of triangle bottom baffle 7, it is ensured that fan
The both sides iron liquid liquid level of slag trap 1 is consistent in shape bag casting process.
Above description is explanation of the invention, is not the restriction to inventing, and limited range of the present invention is referring to right
It is required that, in the case of without prejudice to spirit of the invention, the present invention can make any type of modification.
