This was a key enterprise designated by the former Ministry of Machinery Industry for manufacturing heavy-duty metal processing machinery like plate bending machines and multi-roll leveling machines. Now, it has grown into a leading domestic production hub for such equipment. It stands at the forefront of 11-roll leveling machine R & D worldwide, integrating cutting-edge international technologies. Though specific details of the 11-Roll Leveling Machine are pending, it is presumably a high-precision model in the enterprise’s core series, dedicated to enhancing plate flatness for sectors such as automotive manufacturing and aerospace.

EZW43V-40X1600 | 40mm | 1600MM | 320MPA |
EZHONG 11-roll CNC Hot Plate Leveller adopts an optimized frame structure, ensuring stable force transmission, a compact appearance, and strong overall rigidity. It can achieve stable leveling under full load without the need for special foundation reinforcement.
Integrating the pressure adjustment and roll gap control mechanism with precise servo drive, the 11-roll Hot Plate Leveller enables accurate positioning of the working rolls and flexible adjustment to adapt to different sheet materials.
The movable beam of the machine is designed for easy access, which greatly facilitates quick roll replacement and daily maintenance of the Hot Plate Leveller.
Equipped with an automatic lubrication system, key components such as rolls, bearings, and transmission parts are regularly lubricated through pipelines, ensuring long-term stable operation of the 11-roll Hot Plate Leveller.
It features an advanced measurement and electrical control system, using a high-performance PLC. Operators can set inlet and outlet parameters based on the sheet’s thickness, width, and material. The system stores process data, allowing for instant recall and modification when needed.
The 11-roll Hot Plate Leveller offers high cost-effectiveness. It saves working hours, minimizes scrap and rework rates, and with simple operation, enables efficient single-person independent operation.
-EZHONG 11-roll CNC Hot Plate Leveller scientifically distributes deformation gradient during leveling: initial rolls achieve 50-55% plastic deformation of plate thickness, with subsequent rolls reducing deformation gradually until final elastic recovery (near-zero deformation), ensuring uniform stress release.
-Designed for medium loads with optimized work roll spacing and diameter, it enhances rigidity to handle both thin and medium-thick plates. High-precision rolling bearings in roll journals reduce friction and slipping, enabling stable straightening of ≥0.3mm thin plates with high accuracy.
-Compared to traditional designs, it boosts transmission efficiency by 15-20%, cutting motor power and energy use. Its sub-roller drive improves workpiece grip, with precise roll gap/angle adjustments and stable guiding mechanisms.
-Work rolls use 50CrNiMo (meeting "JB/T3164-2007"), quenched and tempered to HBW270-300, surface-hardened to HS80-90 (HRC52-58). Hardened layers are 2-4mm (D≤150mm) or 4-6mm (D＞150mm), with Ra0.8μm roughness and h6 tolerance.
-Work roll process: blanking → forging → annealing → rough turning → quenching/tempering → semi-finishing → surface quenching → fine grinding. Three inspections (after blanking, rough machining, finishing) are conducted, with material, heat treatment and flaw detection reports provided.
-Upper work roll stroke features electronic display with ±0.1mm accuracy for precise adjustment monitoring.
The movable beam of the 11-roll leveling machine is designed with an optimized lifting stroke, making it easier to access the roll system and facilitating quick disassembly, replacement, and daily maintenance of the working rolls and supporting components.
Using an intelligent electric lubrication pump for centralized lubrication, key components such as working rolls, support roll bearings, gearboxes, and lead screws are supplied with lubricant through separate pipelines connected to the electric pump, ensuring precise and timely lubrication for each critical part.
Equipped with advanced measurement and electronic control systems, the 11-roll leveling machine is controlled by high-performance PLC from a renowned international brand. On the operation console, inlet and outlet roll gap adjustments can be set based on parameters like plate thickness, width, material, and initial flatness. The PLC features functions for editing, storing, and recalling process parameters, allowing for real-time modification and quick adaptation to different production needs.
Complete protection function: Exposed rotating components such as the roll drive shafts and transmission gears are covered with protective enclosures, while the feed and discharge ports are equipped with photoelectric safety sensors to prevent accidental access during operation.
This metal fabrication equipment is produced in strict compliance with EC safety standards, ensuring full alignment with international safety specifications, and has obtained CE certification to validate its compliance for global market access.
The entire machine adopts integral steel plate welding, featuring a thickened structure that combines durability with an elegant appearance. This design ensures excellent overall stability during operation, enhancing performance reliability in industrial applications.
Accurate processing performance can ensure stable and high-quality leveling effect.
This multi-roll leveling machine is widely utilized across diverse industrial sectors. EZHONG’s multi-roll leveling equipment boasts mature core technology, superior leveling precision, flexible process adaptability, intelligent operation systems, and stable performance even under long-term heavy loads. Its application scope covers automotive parts manufacturing, wind power equipment production, pressure vessel fabrication, and precision hardware processing, playing a crucial role in ensuring the dimensional accuracy, surface quality, and structural integrity of industrial workpieces.
