Forging is a process that using forging machine to maket the metal blank produce plastic deformation, in order to obtain a certainmechanical properties, shape and size. Through forging can eliminate the metal ascast loose defects in the smelting process,
optimize the microstructure, keep the complete metal flow, so the mechanical propertites of forging is generally better than castingof the same materail. Most of the machine important parts whcih require high load andserious working condition apply forgingparts.
Material
Forging material widely use round steel square steel.there are carbon steel alloy steel stainless steel as wll as some non-ferrous
metal whichr mainly applied in areospace and precision industry.
Apperance
Oxidationreaction offorging steel duringthe high temperature process will cause slight kylin grain in the surface of the forged
bucket teeth.Also as forging is made by molding, after removing the allowance slot in the mould, there would be a pearting line in theforged bucket teeth.
Mechanical Property
Forging process can gurantee the continuity of metal fibre,and keep complete metal flow,gurantee good mechanical properties and
long service life of the bucket teeth, which casting process is incomparable.
