Roll Gap Adjustment Assembly For Rolling Mill

The Roll Gap Adjustment Assembly is a heavy-duty mechanical spare part designed for rolling mill stands. It is engineered to precisely regulate and calibrate the roll gap, ensuring optimal dimensional accuracy, surface quality, and uniform thickness of rolled steel products during high-speed industrial processing. Also, it is a good Danieli or Morgårdshammar relative spare parts replacement.

 

 

Material Specifications

Manufactured under strict quality control according to Danieli Morgårdshammar international standards, this assembly utilizes premium-grade industrial steels:

 

Component	Material	Standard	Key Properties
Main Body / Flange	Q355B (Low-alloy high-strength structural steel)	GB/T 1591-2018	Excellent yield strength, impact toughness, and structural rigidity
Pins and Critical Shaft Components	40Cr alloy structural steel	GB/T 3077-2015	High hardenability and wear resistance under continuous mechanical stress
Other Structural Elements	Quality carbon structural steel C40 (45# steel equivalents)	-	Enhanced mechanical endurance

 

Heat Treatment & Hardness:

 

Quenched and tempered hardness for shafts: HB 250-280.

Surface quenching hardness: HRC 50-54 (minimum depth 1mm) for superior wear resistance.
