Roller is the important part for rolling mill. The rollers in pair
or group rolling with pressure to roll the steel. It bears the
dynamic and static load, the affact of abrasion and temperature

Type Of notch
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)→
Wood pallet, steel frame support
Type of shipping

The common cold roll material is 9Cr, 9Cr2, 9CrV, 8CrMoV and so on.
The cold roll required surface quench, and hardness is HS45-105.
The hot roll usually use the material of 55Mn2, 55Cr,60CrMnMo,
60SiMnMo and so on. There are three common roller, such as cast
steel roller, cast iron roll and forge roller. There is also a
small quantity of hard alloy roll in bar and shape rolling mill,
such as tungsten steel.
