Steel Ball Skew Hot Rolling Mill Line
Continuous operations involving heating, rolling, quenching, and tempering.
Compatible with materials such as 65Mn, B2, B3, and GCr15.
Product Introduction
The Steel Ball Skew Hot Rolling Mill Line is a fully automated, continuous production system centered around a skew rolling mill. It integrates processes such as feeding, heating, rolling, heat treatment, and inspection, enabling the continuous manufacturing of finished steel balls from round steel stock.

Product Advantages
Self-controlled technology
The skew rolling mill is independently developed and manufactured by the company; we control the entire chain-from equipment to process-facilitating continuous optimization and rapid response to customer needs.
Comprehensive operational protection
Features automatic control of quenching entry temperature, automatic rapid roll retraction, and fixed-point feeding, effectively protecting the equipment and minimizing downtime losses.
Quick size changeover
Switching between steel ball specifications is achieved by changing rolls and adjusting guide plates and feed angles; changeover time can be kept within a few hours.
Customization Services
We can configure the Steel Ball Skew Hot Rolling Mill Line to meet specific customer operating conditions and production targets, covering the following aspects:
Size and output matching
Selection of the appropriate ZQ series model based on target steel ball diameter and annual output, along with determination of production line cycle times and equipment quantities.
Customized roll pass design
Design of single-start, double-start, or multi-start pass profiles based on steel ball specifications and material properties to ensure rolling precision and production efficiency.
Flexible automation levels
Options for semi-automated or fully automated solutions, including automatic feeding, induction heating, in-line quenching and tempering, and inspection systems.
Heat Treatment Process Optimization
Process parameters-such as quenching temperatures and tempering durations-are customized based on specific material grades (e.g., 65Mn, B2, B3, GCr15).
On-Site Layout Adaptation
Production line layouts are designed to align with the customer's factory space, power supply conditions, and interfaces with upstream and downstream equipment.
Comprehensive Support
Services include guidance on installation and commissioning, operational training, and the supply of critical spare parts to ensure stable production line operation.
FAQ
Q: What is the difference between a Steel Ball Skew Hot Rolling Mill Line and a standalone skew rolling mill?
A: A standalone skew rolling mill performs only the rolling and forming process, whereas the production line integrates feeding, heating, rolling, quenching and tempering, and inspection into a single system; customers receive a complete production solution that transforms round steel bars into finished steel balls.
Q: Do you provide guidance for overseas installation and commissioning?
A: Yes, we do. For overseas projects, our company can dispatch technical personnel to the site. The buyer is responsible for round-trip airfare, local transportation, and accommodation and meal expenses, as well as a standard daily allowance of $150 USD per person (calculated based on flight dates); the buyer is also responsible for providing on-site translation services.
