Embodiment
As shown in Figures 2 and 3, the sector of the present utility model with fan-shaped slag trap includes：Fan section and area of slagging tap
9, area 9 of slagging tap is in the upper end in fan section, it is characterised in that：Fan section by the straight baffle plate 8 of the cast gate circular arc 3, the triangle that are sequentially connected,
Triangle bottom baffle 7, bag bottom baffle 6 and fan shape baffle 5 are formed, and slag trap 1 is also equipped with fan section, and cast gate circular arc 3 is to fan
Shape bag 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 fan-shaped Bao Xuan
Turn the circular arc that center 4 is the center of circle, the circular arc of fan shape baffle 5 accounts for its 40 °~70 ° of circular arc justified on a radius, and slag trap 1 arrives
The radius of fan-shaped bag pivot 4 is the 1/5~1/3 of the radius of fan shape baffle 5 to fan-shaped bag pivot 4, the circle of slag trap 1
The angle of arc and 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 exists
In the fan section of the top of triangle bottom baffle 7, the bottom of slag trap 1 is identical away from the distance between triangle bottom baffle 7.Slag trap 1 by
Refractory material is made.
For fan-shaped bag pivot 4 positioned at the lower section of area 9 of slagging tap, the radius of cast gate circular arc 3 is less than the height in area 9 of slagging tap.Wrap 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 present utility model fan-shaped compared with existing fan-shaped bag with fan-shaped slag trap, due to slag trap 1, fan-shaped gear
Plate 5 and cast gate circular arc 3 are concentric circles, and fan-shaped bag pivot 4 is actual pivot of the fan-shaped bag in casting process simultaneously.
The bag bottom baffle 6 of sector bag makes the shape shown in Fig. 2.In the inside in fan section plus fan-shaped slag trap 1.Iron liquid is from pushing off the slag
Flowed out between plate 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 sector
The sectional area of bag cast gate.Following beneficial effect can be produced after making the change shown in Fig. 2 to fan-shaped bag：
1st, the fan-shaped bag pivot 4 of fan-shaped bag is the circle of slag trap 1, fan shape baffle 5 and cast gate circular arc 3 simultaneously in Fig. 2
The heart, the iron liquid that can so ensure outflow in any unit interval when constant angular velocity turns over bag is equivalent.
2nd, the outflow mode of iron liquid is changed among sector bag by original successively outflow from top to bottom and flowed out, so
Outflow mode allow in iron liquid light impurities thing 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 casting flaw probability caused by clinker.
3rd, slag trap 1 gos deep into the place plane of bag bottom baffle 6, ensure that and remains 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 iron liquid outflow fan-shaped bag of the scum silica frost with cast latter stage.
5th, triangle bottom baffle 7 is designed to inclined-plane rather than horizontal plane, after ensure that fan-shaped bag casting complete, residual it is a small amount of
Iron liquid and the scum silica frost kept off can smoothly return to bag bottom along the inclined-plane of triangle bottom baffle 7, will not result in blockage.
6th, slag trap 1 and the sectional area in the gap of triangle bottom baffle 7 are greater than the sectional area of fan-shaped bag cast gate, ensure that fan
The both sides iron liquid liquid level of slag trap 1 is consistent in shape bag casting process.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of without prejudice to spirit of the present utility model, the utility model can be made any type of
Modification.
