The basic principle of stainless steel parts feeding: To eliminate shrinkage cavities in steel castings with risers, it is necessary to install appropriate risers at the last solidification position of the steel casting and ensure sequential solidification. The purpose of ensuring sequential solidification is to ensure that there is always "feeding through" during the solidification process of the steel casting. This channel ensures that the molten steel in the riser can be replenished into the casting. Sometimes, due to inadequate design, the feeding channel is prematurely interrupted during the solidification process, preventing the molten steel in the riser from flowing to the feeding area and failing to fully exert the feeding function of the riser, resulting in shrinkage cavities in the steel castings. Therefore, the feeding capacity is not only determined by the riser itself, but also by the conditions that form the feeding channel. The main factors affecting the feeding channel are the thickness of the casting and the heat absorption rate of the mold.

　　The width of the cast steel gear flange part is6The diameter of the hot joint circle at the junction of the rim and the spoke plate isD,D＞bThe gating system is set at the parting surface. Obviously, the flange at the root of the riser is relatively hotDIt solidified first, blocking the replenishment channel of the molten steel. At this time, although there was still a considerable amount of molten steel in the riser that could be replenished, shrinkage cavities appeared at the lower part.

　　As can be seen from the above, how to ensure the unobstructed feeding channel is an important issue in controlling the solidification process of steel castings and also a problem that must be considered in the design of risers. Vertical or horizontal feeders are placed in steel castings to control the solidification of the castings. The essence is to ensure the unobstructed feeding channel, allowing the feeding steel liquid in the riser to flow smoothly to the feeding area.
