Huahan Intelligent Launches Advanced Steel Core Conveyor Belt Vulcanizing Line for High-Tensile Mining Belts
Release time
Sep 14,2026
DALIAN, China – September 14, 2026 – Huahan Intelligent , a Dalian-based high-tech enterprise focused on industrial safety protection, today unveiled its new Steel Core Conveyor Belt Vulcanizing Line, a complete production solution engineered to manufacture and splice high-tensile steel cord conveyor belts with consistent, long-lasting joint quality.
Steel cord conveyor belts carry some of the heaviest loads in bulk material handling, yet the reliability of any belt ultimately depends on the quality of its vulcanized splices. Built for belts rated from ST1000 up to ST10000, the new line combines precision heating, uniform pressure and intelligent process control, enabling operators to produce strong, repeatable splices that match the strength of the belt carcass itself.
Complete process coverage in one integrated line
The Steel Core Conveyor Belt Vulcanizing Line spans the full workflow — from belt preparation, cord alignment and cover-sheet lay-up, to hot vulcanization, cooling and post-cure inspection. System configurations can be matched to each customer's belt width, cord diameter and rated-strength requirements, and the modular frame design allows the equipment to be installed and commissioned on site with minimal disruption to existing operations.
Technology highlights
- Precise temperature control – Multi-zone heated platens maintain a vulcanizing temperature of approximately 145 °C (±5 °C), ensuring even curing across the entire splice area.
- Uniform high pressure – Hydraulic pressure of ≥1.2 MPa distributes force evenly over the joint, eliminating trapped air and voids that weaken splice strength.
- Intelligent control system – PLC-based operation with parameter locking, automatic recording of temperature, pressure and cure time, plus diagnostic alarms, delivers documented and repeatable splice quality.
- Faster cycle times – Rapid heating and forced cooling shorten the curing cycle, helping operators minimize downtime on critical conveyor lines.
- Safety by design – Protective interlocks, clear status feedback and ergonomic operation reduce human error and keep field crews safe.
Why splice quality matters
Weak joints are the most common failure point on a steel cord conveyor belt. A splice vulcanized under controlled temperature and uniform pressure achieves joint strength close to that of the belt carcass, significantly extending belt service life and reducing unplanned stoppages — a critical factor for operators where every hour of lost conveyor uptime carries a heavy production cost.
Applications across industries
The line is suitable for a wide range of applications, including underground and open-pit mining, coal preparation plants (including flame-retardant belts), ports and terminals, cement plants, metallurgy and power generation. It also accommodates fabric-core (EP/NN) conveyor belts, giving belt manufacturers and service companies one flexible production platform.
Quality and after-sales support
All equipment is manufactured under the company's ISO 9001 quality management system and subjected to strict factory acceptance testing before delivery. Huahan Intelligent provides complete after-sales support, including installation and commissioning, operator training, spare parts supply and responsive technical assistance for customers worldwide.

FAQ
What is a Steel Core Conveyor Belt Vulcanizing Line? It is a complete production system for manufacturing and hot-splicing steel cord conveyor belts, covering belt preparation, lay-up, vulcanization, cooling and inspection under controlled temperature and pressure.
Which belt ratings can the line handle? The line supports steel cord belts rated from ST1000 up to ST10000, as well as fabric-core (EP/NN) belts and flame-retardant belts for coal mining applications.
What temperature and pressure are used for vulcanization? Typical curing parameters are approximately 145 °C (±5 °C) with a hydraulic pressure of ≥1.2 MPa, ensuring uniform, void-free joints.
How does the line reduce conveyor downtime? Precise process control produces stronger, longer-lasting splices, while rapid heating and cooling shorten each repair or splicing cycle — both reduce unplanned conveyor stoppages.
