UpsettingThe ring rolling process begins with the upsetting of the starting stock on flat dies at its plastic deformation temperature.II. PiercingPiercing involves forcing a punch into the hot upset stock displacing metal radially and leaving a thin web of metal at the bottom.III. ShearingA subsequent operation, shearing, removes the thin web producing a completed hole through the stock.IV. PreformingThis stock, referred to as a blank or preform, is now ready for the ring rolling process.V.FormingThe doughnut-shaped preform is placed over the mandrel.As the preform is rotated in the mill, the mandrel begins to apply pressure toward the main roll. At the same time, the axial cones apply pressure toward each other.As a result of the radial and axial pressure, the ring's OD and ID gradually increase while the thickness and wall section are reduced.Axial forging/ forged shaftDiameter(mm)Height(mm)Single weight(kg)Material 180~1000500~850012000 or lessCarbon structure steel/alloy structure steel/low alloy steel180~650500~600010000 or lessalloy steel/spring steel/stainless steel/heat resistant steel150~400400~300010000 or lesshigh temperature alloy steelRing forging/forged ring/annular forging/gear forging/steel sleeve/steel cylinderDiameter(mm)Height(mm)Single weight(kg)Material 800~3500100~5004200 or lessCarbon structure steel/alloy structure steel/low alloy steel/alloy steel/spring steel/stainless steel/heat resistant steel/high temperature alloy steelModule forging/forging blockThick(mm)Width(mm)Single weight(kg)Material 100~600100~160018000 or lessCarbon structure steel/alloy structure steel/low alloy steel/alloy steel/spring steel/stainless steel/heat resistant steel/high temperature alloy steelForging barsDiameter(mm)Height(mm)Single weight(kg)Material 80~6501600012000 or lessCarbon structure steel/alloy structure steel/low alloy steel80~6501600010000 or lessalloy steel/spring steel/stainless steel/heat resistant steel/high temperature alloy steelForging discsDiameter(mm)Height(mm)Single weight(kg)Material 150~1000100~5004200 or lessCarbon structure steel/alloy structure steel/low alloy steel/alloy steel/spring steel/stainless steel/heat resistant steel/high temperature alloy steelHow to pack
