A professional rolling mill supplier will tell you what core equipment and functional modules an excellent rolling mill should have.
1. Core equipment of the main column
Working base
Roll: The core component directly involved in the plastic deformation of metal, the material to be rolled should be selected based on its properties (such as cold rolling requires a high hardening layer depth)
Roll bearing: Needs to have a low friction coefficient and high bearing capacity. Rolling mills for sheet metal often use rolling bearings, while profile rolling mills mostly use sliding bearings
Frame: Closed frame (high rigidity) is suitable for initial rolling machines, while open frame is convenient for changing rolls
Transmission system
Main motor: Provides power. Modern rolling mills mostly use high-power DC or AC motors
Reducer and gear base: Transmits torque and adjusts speed
2. Key auxiliary devices
Roll adjustment system
Radial adjustment: Controls the thickness of the roll gap (hydraulic press-down device can achieve AGC automatic control)
Axial adjustment (roller displacement): Optimizes the profile of the sheet metal, such as the axial movement technology of the middle roll in a twenty-roll rolling mill
Roll shape adjustment: Controls the profile through bending rolls or hydraulic cylinders
Automation and detection equipment
AGC system: Monitors thickness deviations and adjusts the roll gap
Thickness gauge and profile rollers: Ensures product dimensional accuracy
Oil mist removal system: Improves the working environment
3. Efficient production support modules
Fast roll changing device
Design of small vehicle or entire frame for roll changing, the roll changing time can be shortened to 5-8 minutes
Cooling and lubrication system
Steel strip cooling process: Controls the rolling temperature
Scraping oil system: Removes residual oil on the surface
4. Special rolling mill configurations (taking high-end models as an example)
Multi-roll rolling mill (such as twenty-roll): Uses small-diameter working rolls + multiple supporting rolls structure, suitable for high-precision thin strip rolling
HC rolling mill: Dynamically adjusts roll shape through hydraulic bending technology The design of an excellent rolling mill should be based on specific rolling requirements (such as material type, precision, and output), and the selection of equipment combinations should be made accordingly, while also emphasizing the coordinated control of each system.
