Detail Information
Overview
Thermite Welding System
This comprehensive thermite welding system is engineered for seamless rail joining in railways, ports, steel mills, power plants, and heavy industrial environments. It offers an integrated solution including premium-grade thermite flux, disposable crucibles, precision sand molds, and a full suite of welding tools—from preheaters to flash removers and grinders. Fully compliant with standards such as TB/T1632.3-2014, the system supports all major rail profiles, including grooved rails (59R2/60R2), QU-series crane rails, and international standards (UIC, BS, CR, A/S series). It also delivers reliable welding for cathode steel bars in aluminum smelters. Designed for reliability in harsh conditions—including high magnetic fields, dust, and extreme temperatures—the system has been deployed in metro lines, high-speed railways, port cranes, and Belt & Road infrastructure projects worldwide.
System Components
⚪ Core Consumables
● Thermite Welding Flux: Customized per rail profile (e.g., 60DE, QU100, 59R2); high-purity formula ensures dense, defect-free weld microstructure.
● Disposable Crucible: Made of refractory ceramic; patented design; single-use to prevent contamination.
● Precision Sand Mold: Precision-molded to match specific flux and rail profile for optimal weld geometry and surface finish.
● Sealing Sand: Used to seal joints between sand mold sections, preventing molten steel leakage during pouring.
⚪ Welding Tools
● Preheater: Propane/oxygen flame system for uniform preheating of rail ends prior to welding.
● Burner Nozzle: Interchangeable nozzle to suit different rail profiles and optimize flame coverage.
● Oxygen Flow Meter: Accurately regulates oxygen flow to maintain preheat temperature within 350–500°C.
● Propane Regulator: Stabilizes propane output pressure for safe and efficient preheating operation.
● Ignition Powder Stick (High-Temp Igniter): Quick-ignition stick for reliable thermite flux ignition; simple and highly effective.
● Crucible Support Bracket: High-temp steel bracket for stable crucible support and controlled pouring.
● Crucible Lid: Reduces heat loss, minimizes spatter, and enhances reaction stability.
● Slag Catcher: Collects post-reaction slag to maintain a clean and safe work area.
⚪ Auxiliary Fixtures
● Rail Alignment Jig: Aligns rail ends precisely with ≤0.5mm tolerance in height and alignment.
● Bow Clamp: Arc-shaped clamp ideal for grooved rails or confined working spaces.
● Shim Blocks: Used with alignment jigs to fine-tune rail elevation and smoothness.
● Rail Alignment Straightedge: Available in 1m/2m lengths; used to verify rail straightness before and after welding.
● Welding Fixtures: Secures sand mold relative to rail to prevent displacement during metal pouring.
