Plate Leveling Machine

Plate Leveling Machine is essential metal processing equipment used to flatten bent, warped, wavy steel plates after cutting, stamping and rolling. Through repeated alternating bending between upper and lower staggered rollers, internal residual stress of raw plates is removed to get qualified flat blanks for subsequent cutting, welding and machining.

Working Principle

Workpieces are fed into roller gaps and bent up and down continuously. With gradually reduced bending depth from inlet to outlet, plates complete elastic-plastic deformation and rebound elimination to reach required flatness. CNC hydraulic type adjusts roller clearance automatically according to plate thickness and material.

Key Advantages

Heavy-duty welded frame, high structural rigidity, small deformation under heavy load, stable leveling accuracy.

Alloy quenched work rolls with backup roller support, wear-resistant, less plate surface scratch.

Hydraulic servo + PLC touch control, auto gap setting, easy operation, save debugging time.

Centralized lubrication system, low failure rate and convenient maintenance.

Technical Range

Processing thickness: 0.5mm ~ 100mm

Max working width: customizable from 1000mm to 5500mm

Suitable material: carbon steel, alloy steel, high-strength steel, ship plate, boiler plate

Flatness precision: 0.3~0.8mm per meter

Application

Widely used in steel service center, shipbuilding, engineering machinery, steel structure, container and boiler manufacturing industries.

Types

Thin plate leveler (9~23 rollers): for 0.5–6mm sheets

Medium plate leveler (7/11 rollers): for 6–40mm steel

Heavy hydraulic leveler (5/7 rollers): for thick high-tensile steel above 40mm
