Blank Bar Gear Forging For 5000mm Numerical Ring Rolling Machine
Product Desciption:
Rack is the main parts of mining equipment, after partial forging
to process into tooth formation,then assemble .the whole round or
other formation.Rack is mainly used for basement rotation parts of
super big scale mining equipment,since lots of big scale mining
equipment parts can not be accomplished by forging and casting,even
if it can be forged or casted the cost is high,so adopt partial
forging,process,finally to assemble to meet the working
requirements.
Forging Process
Forging process flow quality control: Raw material steel ingot into
warehouse(test the chemical content) → Cutting→ Heating(Furnace
temperture test) → Heat treatment after forging(Furnace temperture
test) Discharge the furnace(blank inspection)→ Machining→
Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT,
mechanical properties, hardness, grain size)→ Finish machining→
Inspection (dimension)→ Packing and Marking(steel stamp, mark)→
