Processo di produzione delle piastre antiusura

NM series wear plates provide excellent abrasion resistance for heavy-duty industrial equipment. With professional taglio, flessione, perforazione, saldatura, and finishing services, these plates can be fabricated into ready-to-install solutions for mining, costruzione, material handling, and recycling applications.

Proper processing ensures maximum equipment longevity and operational efficiency while minimizing maintenance costs.

Categoria: Serie NM

Descrizione

NM series wear plates (such as NM400, NM450, and NM500) sono ampiamente utilizzati nel settore minerario, costruzione, and heavy industrial machinery for their excellent abrasion and impact resistance. A complete wear plate manufacturing process ensures that these plates are delivered in ready-to-install form, meeting both mechanical performance and dimensional requirements.

Teda Ganghua provides a comprehensive range of NM series wear plate processing and manufacturing services for industrial clients.

1. Cutting and Shaping

NM series wear plates can be precisely cut and shaped to meet equipment specifications. Common cutting methods include:

Cutting Method	Suitable Material	Note
Taglio al plasma	NM400 / NM450	Veloce, precise, minimal heat distortion
Taglio laser	Thin NM plates	Alta precisione, smooth edges
Taglio con ossitaglio	Thick NM plates	Preheating recommended for high hardness
Water Jet Cutting	Complex shapes	No heat-affected zone, preserves surface properties

This allows plates to be shaped for buckets, cade, tramogge, and conveyor systems.

2. Piegatura e formatura

Bending is essential for applications such as hoppers, secchi, and chute liners:

NM plates are spento e temperato, with moderate toughness, allowing bending with proper tooling and radius.
Preheating may be applied for thicker plates to avoid cracking.
Bending ensures proper coverage of wear-prone surfaces and optimal fit.

3. Drilling and Bolt-On Preparation

For modular wear plate systems:

Holes are drilled for bolts to attach plates securely to equipment.
Carbide-tipped or high-speed steel drills are used for hardness.
Bolt patterns can be customized for quick replacement and maintenance.

4. Welding and Overlay

Permanent attachment of NM series plates requires controlled welding techniques:

MMA / Stick Welding, ME / MAG, E Saldatura ad arco sommerso (SEGA) are commonly used.
Low-hydrogen electrodes prevent cracking.
Preheating may be necessary for plates above certain thicknesses.
NM plates can be overlaid or welded to enhance durability in high-wear zones.

5. Surface Preparation and Finishing

Remove rust, scala, and oil before processing.
Smooth edges to reduce stress concentration.
Optional protective coatings for corrosion prevention.

6. Typical Applications for NM Series Plates

NM series wear plates are commonly applied in:

Estrazione & Estrazione: Fodere del frantoio, grizzly bars, cade, and hoppers
Macchinari da costruzione: Loader and excavator bucket protection
Attrezzatura industriale: Conveyor components, feed hoppers, truck bodies
Riciclaggio & Gestione del materiale: Shredder hammers, screen liners, e indossare barre
