Different methods have different forging processes of planetary ring gear wheel, with the longest hot forging process, the general order: forging billet cutting; forging billet heating; blank roll forging equipment; die forging; trimming; punching; correction; middle size and surface defect inspection within aluminum ring, inspection forgings; inner ring forging heat treatment plant to eliminate the internal ring gear forging stress, improve metal cutting; cleaning, mainly to remove surface oxidation leather; correction; check to go through the general appearance and hardness of forging checks, forging important to go through chemical analysis, mechanical properties, residual stress testing and nondestructive testing. Pieces are made by forging method piece forging with impact, forged out of the piece. Casting is casting method made pieces. Casting is mold or model, fill pour molten steel, cast out of the pieces. cast metal smelting meet certain requirements and poured into the mold in liquid, solidified by cooling, after clearing the entire treatment to give a predetermined shape, the size and performance of the casting (part or blank) of the process of the ring gear coupling, Zhenjiang ring gear, Super League Super League forging Forging Co., Ltd.
