Problems solved by technology
[0002] In casting production, if you want to obtain high-quality castings, you must first have a mold with an excellent gating system. An excellent gating system must not only ensure that the mold is filled within the specified time, but also have good slag retention, degassing, Feeding function, the current production of large brake discs for trucks has been using a relatively traditional pouring system, which has many defects such as sand holes, pores, and shrinkage porosity, and the manufacturing cost remains high. Therefore, those skilled in the art provide a centrifugal setter Slag bag and pouring method thereof, to solve the problems proposed in the above-mentioned background technology

Embodiment Construction
[0017] see Figure 1~2 , in an embodiment of the present invention, a centrifugal slag collecting bag includes a horizontal gate, one end of the horizontal gate is integrally formed with a straight gate buffer pit, and the other end of the horizontal gate is integrally formed with a feeding pit, The upper surface of the shrinkage pit is integrally formed with a diversion groove structure, and the outside of the shrinkage pit is also integrally formed with an ingate.
[0018] Preferably: the angle between the centerline of the horizontal gate and the central line of the inner gate is an acute angle, and the horizontal gate and the inner gate are located on the same horizontal line, in order to increase the tangent of molten iron entering the feeding pit Spin distance, increase centrifugal spin speed.
[0019] Preferable: the shape of the horizontal gate is gradually shrinking from right to left, and the bottom of the buffer pit of the horizontal gate and the straight gate is l...

Abstract
The invention relates to the technical field of casting and discloses a centrifugal slag collecting bag. The slag collecting bag comprises a transverse pouring gate, wherein a straight pouring gate buffer pit is integrally formed on one end of the transverse pouring gate, a feeding pit is integrally formed on the other end of the transverse pouring gate, a flow guide groove structure is integrallyformed on an upper surface of the feeding pit, and an inner pouring gate is further integrally formed on the outer side of the feeding pit. The slag collecting bag is advantaged in that the defect ofassembly connection is avoided through an integrally-formed pouring system, the centrifugal separation principle is fully and effectively utilized for degassing and slag collection, flow guide grooves which are not seen in historical materials are designed, centrifugal rotation of the molten iron is more stable and faster, the specification design of an inner pouring gate is not restrained by gate slag feeding any more, the feeding capacity can be improved to the maximum degree, in addition, the centrifugal slag collecting bag is shaped through experiments of adjusting sizes of all parts formany times and is small in mass and best in centrifugal rotation, and thereby the centrifugal slag collecting bag has the good slag blocking, degassing and feeding functions, the comprehensive castingyield is increased, cost is reduced, energy is saved, and consumption is reduced.
