Vertical Lifting Solutions for DRI Applications

QBF Rubber delivers sidewall belt-focused support solutions for hydrogen-based DRI shaft furnace vertical lifting. Belt tracking correction systems, vertical-section anti-float devices, on-site hot vulcanization, installation guidance and periodic system diagnostics. Proven on Baowu Zhanjiang and Algerian MIDREX projects. Reduce unplanned downtime for green-steel DRI conveying lines.

Hydrogen-based direct-reduction (DRI) shaft furnaces are one of the fastest-expanding green-steel production routes across the globe. Many green-steel plants deploy steep-angle corrugated sidewall belt conveyors to move hot DRI, oxide pellets and other abrasive bulk feeds over vertical or near-vertical conveyor segments. These belt systems run 24/7 under harsh metallurgical thermal-cycling conditions; even minor sidewall-belt malfunctions can trigger costly full-plant production interruptions for DRI lines.

Plant maintenance and project engineering teams frequently face recurring pain points on these critical vertical conveyor runs: persistent belt wander within vertical sections, belt lifting / floating away from idler rolls, premature splice failures, ambiguous on-site erection procedures, and lack of structured periodic condition audits. Minor misalignment or belt-float issues gradually wear down sidewalls and cleats, bringing spillage, unplanned stops and inflated repair costs for continuous DRI operations.

QBF rubber delivers application-specific hardware modules together with matched field-service packages purpose-built for DRI shaft-furnace vertical sidewall-belt conveying. We do not supply complete conveyor steel frames. Our offering addresses those well-documented vertical-segment failure modes for both new-build and retrofitted DRI conveyor installations.

Core Components & Specialised Field-Service Packages

Drawing on 50-years of hands-on European rubber-conveying manufacturing know-how and Sino-German joint-engineering resources, QBF rubber supplies hardware plus hands-on site support optimised for non-stop DRI metallurgical operating environments:

• Sidewall belt guide roller systems: Purpose-calibrated tracking assemblies for vertical-inclined DRI conveying routes. Designed to counter thermal-induced belt drift, uneven material-load distribution and cyclic metallurgical operating shocks. Cuts edge chipping, sidewall abrasion and spillage driven by persistent belt wander.

• Vertical-section anti-float devices for sidewall belts: Custom-fitted mechanical assemblies restraining sidewall-belt lift-off on vertical or near-vertical runs. Prevents belts floating away from idler rollers under combined DRI payload and thermal fluctuation, lowering abnormal rubber fatigue and unexpected tear-off hazards.

• On-site hot-vulcanised belt splicing: Our directly-employed field technicians perform metallurgy-grade hot-vulcanization work at customer DRI plant sites. Strict control over splicing temperature, pressure and hold-time produces robust splice joints resistant to thermal cycling and heavy DRI payloads, avoiding premature cold-splice failures amid round-the-clock production cycles.

• Professional installation guidance: Senior conveyor engineering staff deliver step-by-step technical guidance during new-unit erection or belt-replacement work at DRI facilities. Our support helps local site crews achieve correct pulley parallelism, tension set-points and component alignment from commissioning, to avoid preventable early-stage tracking-related troubles.

• Periodic on-site survey & system diagnostic service: Scheduled on-plant inspections for live DRI vertical conveyor lines. Our engineers evaluate belt health, tracking performance, anti-float assembly condition, tension balance and splice integrity. We deliver practical diagnostic reports with prioritised maintenance recommendations, enabling site teams to shift from reactive emergency repairs to planned predictive upkeep.

Core Competitive Advantages

DRI-Optimised Hardware Built for Vertical Sidewall-Belt Operating Realities

Most off-the-shelf belt-correction hardware originates for mining or port duties, without accounting for unique thermal-cycle stress and non-stop production rhythms inside DRI green-steel facilities. QBF rubber tunes tracking geometry and anti-float mechanical structures specifically for DRI vertical-segment working modes. Components take temperature swings, pellet-particle abrasion and continuous plant operation fully into consideration for hydrogen-based shaft-furnace workshops.

Combined Hardware-and-Service Single-Point Accountability

Many steel-plant projects source tracking hardware from one vendor and contract separate third-party crews for vulcanization, installation oversight and condition surveys. This fragmented supply model creates finger-pointing risks once performance gaps occur. QBF rubber provides both custom hardware modules and matching field-service resources under one unified technical team. We accept clear accountability for combined performance of our components plus our on-site execution work.

Sino-German Joint-Engineering Backed by European Metallurgical Conveying Benchmarks

Our cross-border engineering team references proven European metallurgical-conveying design standards. We validate tracking-system logic and anti-float-device mechanical limits via simulated DRI vertical-segment load cases. Plant operators receive application-optimised hardware without the full import premium of niche overseas-sourced special components.

In-House Field Engineers, No Outsourced Third-Party Subcontractors

All high-risk on-site tasks including hot vulcanization, system surveys and installation guidance are completed by QBF rubber directly-employed technical staff. Core metallurgical-zone work never gets subcontracted to casual local crews, securing consistent execution quality for DRI production-area interventions.

Compatible for Both New-Build & Retrofit DRI Shaft-Furnace Projects

Our tracking correction hardware, vertical anti-float assemblies and complete service packages suit two major project scenarios: brand-new DRI-plant conveyor construction, and retrofitting onto already-operational vertical sidewall-belt lines. Full conveyor-frame replacement is not mandatory to resolve vertical-segment belt-wander or belt-floating faults.
