Precision Work Rolls (16-68mm) with Chrome-Plated
Our precision-engineered work rolls, covering a comprehensive diameter range from 16mm to 68mm, are systematically paired with advanced chrome-plated back-up rolls to deliver exceptional durability and operational stability in the most demanding strip processing applications. The electroplated chrome surface treatment significantly enhances wear resistance through increased surface hardness (reaching HV 800-1000) while simultaneously reducing the coefficient of friction. This synergistic combination ensures consistent long-term performance and substantially extends the service life of both the roll system and the processed strip materials, even under continuous high-load production conditions.
Work roll for the right machines are subject to strict quality requirements. Key features include:
- High surface hardness and uniform distribution of hardness throughout the surface;
- the presence of a deep reinforced layer in the roller body;
- increased strength and impact viscosity of both the neck and the main part of the roller;
- Exceptional wear resistance, stain resistance and ability to withstand extreme workloads.
Due to these properties, the rollers ensure stable operation of high-speed, large-scale and precision equipment for metal processing, which is especially important in metal rolling production and processing of sheet and roll material.
Core strengths of work roll
- Comprehensive Size Spectrum: Our work rolls encompass an extensive diameter range from 16mm to 68mm, meticulously engineered to address the complete spectrum of leveling requirements. This includes precision processing of ultra-thin electronic foils (0.1-0.3mm) through to heavy-gauge steel strips (3.0-8.0mm), with intermediate sizes optimized for specific material characteristics and production parameters.
- Advanced Wear Resistance Technology: The chrome-plated back-up rolls feature a dense, uniform surface coating applied through controlled electroplating processes, achieving exceptional surface hardness of HV 800-1000. This advanced surface treatment reduces abrasive wear by 60-70% compared to conventional surfaces, effectively extending maintenance intervals by up to 50% while maintaining consistent dimensional accuracy throughout the operational lifecycle.
- Optimized Operational Stability System: Through precision dynamic balancing and advanced roll core design, our balanced roll system effectively minimizes vibrational harmonics during high-speed operation. This engineering excellence ensures perfectly distributed tension across the entire strip width, achieving superior flatness tolerances within I≤2 while eliminating surface imperfections caused by irregular tension patterns.
- Friction Reduction & Energy Efficiency: The micro-smooth chrome surfaces (Ra ≤ 0.1μm) create an optimal bearing interface that decreases the coefficient of friction by 40-45%. This engineering innovation directly translates to 15-20% reduction in drive power requirements while completely preventing material adhesion and transfer, resulting in enhanced operational efficiency and reduced energy consumption.
Application areas and materials:
Rollers are widely used in various industrial fields, especially in metal processing and steel rolling production.
They are usually made of high-quality stainless steel or carbon steel and often undergo strengthening coating treatments such as chrome plating or heat treatment to improve wear resistance and service life.
These components are crucial for the proper operation of production lines, rolling mill equipment, and sheet metal processing machinery, as they ensure high precision and stability in the production process.
Tension straightening machines are known for their high precision, efficiency, and stability, and therefore have a wide demand in the following fields: • Automotive manufacturing (production of body and chassis parts);
- Automotive manufacturing (production of body and chassis parts);
- Manufacturing of household appliances (production of metal casings for refrigerators and washing machines);
- Construction industry (rolling of steel sections and plates).
