Wear Solutions & Expertise & Customer-Tailored Service：

Bortome specializes in manufacturing cemented tungsten carbide mill rolls designed for the harsh operating conditions of hot rolling mills producing wire rod and rebar.

We offer two delivery options to match your production needs:
– Semi-finished rolls with precision-ground inner diameter and thickness
– Fully finished rolls manufactured directly to your drawings

Our carbide rolls are available up to Ø600 mm outer diameter with a maximum thickness of 300 mm.

Application in Wire Rod Rolling:

Wire rod is formed by hot rolling metal billets between two rolls to achieve the required shape and dimensional accuracy.
During operation, the rolls are exposed to extreme combined stresses:
– High thermo-mechanical fatigue
– Severe abrasive and adhesive wear
– Radial compression and impact during billet biting
– Thermal shock and thermal fatigue
– Hoop stresses from mounting and fitting

The wire rod rolling process includes four key stages:
Roughing Stand → Intermediate Stand → Block Mill → Finishing Stand

Material Properties & Advantages:

The performance of tungsten carbide is determined by critical structural factors:
– Binder type and content
– WC grain size
– Grain morphology and uniform distribution

Bortome tungsten carbide rolls are the premium recommended material for Intermediate Stands, Block Mills, and Finishing Stands, providing exceptional wear resistance, thermal stability, and service life under demanding hot rolling conditions.

Manufacturer of High quality tungsten carbide rolls for rolling mills YG15最先出现在Tungsten carbide, wolfram carbide, cemented carbide products, manufacturers。

Tungsten Carbide Composite Brazing/Welding Rods are high-performance wear-resistant cutting consumables specifically designed for high-wear and high-load industrial working conditions. Manufactured via powder metallurgy sintering process, they composite high-hardness tungsten carbide particles with high-strength metal matrices (nickel-based, copper-based, nickel-chromium-boron, nickel-bronze and other multi-alloy systems). Their core function is to extend the service life of key equipment components and reduce operation and maintenance costs.

Core performance advantages of tungsten carbide composite rods:

Material Guarantee: Composed of high-purity tungsten carbide particles (WC content ≥ 85wt%) and high-quality metal matrices, with uniform particle distribution, featuring both high hardness (HRA ≥ 90) and strong toughness (flexural strength ≥ 3000MPa), capable of withstanding extreme wear and impact loads;
Graded Adaptation: Adopting “precise particle size grading” design, cutting grade (coarse/large particles) is equipped with sharp polygonal tungsten carbide structure, suitable for cutting working conditions such as steel and rock; wear-resistant grade (fine/small particles) optimizes particle density, effectively resisting abrasion from media like soil and gravel;
Process Compatibility: Mainly compatible with oxyacetylene brazing process, some models support TIG welding, enabling convenient and efficient construction. Can be directly applied to clean steel surfaces with high welding bonding strength and no easy detachment.

Applicable industries and components of tungsten carbide composite rods:

Core Service Industries: Oil and gas drilling, geothermal development, mining, geological exploration, earthwork engineering, agricultural machinery, etc.;
Typical Adaptable Components: Stabilizers, DTH hammers, reamers, drill pipes and joints, washover shoes/rotary shoes, fishing tools, wear-resistant liners, auger drills, grooving machines and other key high-wear components.

Tungsten carbide punches details:

We are able to make the punches as per your drawings.

Utilizing five-axis simultaneous grinding and mirror polishing processes, the core precision indicators reach the high-end level of the industry:

Dimensional tolerance: Ultra-precision level ±0.001mm (higher precision can be customized as needed);

Roundness/concentricity: ≤0.003mm, radial runout ≤0.002mm;

Surface roughness: Ra≤0.05μm (mirror finish), reducing material adhesion and friction loss during the stamping process and ensuring the surface finish of the workpiece.

Tungsten carbide sandblasting nozzle details:

Carbide Sandblasting Nozzles – Product Features：

1. Superior Hardness, Ultimate Wear Resistance
Hardness reaches HRA 89-93: The material’s hardness is second only to diamond, giving the nozzle extremely high resistance to erosion.
Extra-Long Service Life: Compared to ordinary ceramic nozzles, lifespan is increased by 5-10 times; compared to steel nozzles, lifespan is increased by more than 20 times. Significantly reduces replacement frequency and downtime.

2. Unique Venturi Design, Doubled Efficiency
Acceleration Principle: Utilizes a precisely calculated Venturi flow channel design (inlet contraction – straight throat – outlet expansion). When compressed air carrying abrasive particles passes through, the airflow velocity can increase to above the speed of sound.
2.1 Significant Results:
Abrasive exit velocity increased by 30%-50%;
Stronger impact force, cleaning efficiency increased by more than 40%;
Concentrated jet beam, larger coverage area, ensuring uniform surface treatment.

3. Excellent Impact Resistance and Toughness
Scientific Formula: Utilizing a “hard phase (WC) + binder phase (Co)” structure, by adjusting the cobalt content (e.g., YG6, YG8 grades), it maintains high hardness while imparting sufficient toughness to the matrix.
Durable and Reliable: Capable of withstanding continuous high-speed impacts from large, high-hardness abrasive particles (such as steel shot and copper ore sand) without easily cracking, chipping, or breaking.

4. Precision Machining and Dimensional Accuracy
High-Precision Forming: Employing isostatic pressing or molding, combined with subsequent precision grinding of the inner and outer diameters.
Small Internal Hole Tolerance: The inner diameter tolerance is controlled within ±0.05mm, with a mirror-like smooth inner wall. This ensures smooth airflow channels, reduces eddy current losses, thereby maintaining a stable injection angle and pressure, and reducing energy consumption.

5. Good High-Temperature Resistance and Chemical Stability
High-Temperature Resistance: Can operate for extended periods in high-temperature environments (withstanding temperatures up to 400°C-600°C) without performance degradation.
Corrosion resistant: It has good resistance to chemical media such as acids and alkalis, and is suitable for working environments in sandblasting rooms that are humid or contain corrosion inhibitors. It is not easy to rust or corrode.

6. Wide range of applications: covering various industrial sandblasting operations such as shipbuilding and repair, auto parts, steel structure corrosion protection, mold cleaning, and surface strengthening/descaling of aerospace components.

Details of carbide anvils:

Three-coordinate dimensional inspection of precision-ground tungsten carbide anvil:

Precautions for using of carbide anvils:

1.Residual Stress Relief
Anvils retain residual stress after finish machining. Prior to use, aging treatments such as natural aging, oven aging, oil boiling, vacuum aging, or ultrasonic aging must be performed. Natural aging requires ≥1 month; oven aging must be conducted at ≤250°C for ≥72 hours.

2.Anvil Assembly Specifications
The tapers of the anvils and steel rings must match, with a contact area ≥90%. Press-fit height should be 8–10 mm for diameters <127 mm and 10–12 mm for diameters ≥127 mm. Avoid point contact between anvils and size spacers to prevent stress concentration.

3.Raw/Auxiliary Material Requirements

Steel rings and size spacers must meet machining accuracy standards. Inner wall surface finish of steel rings: Ra 1.6. Ovality and taper must match anvil geometric tolerances. Size spacer parallelism ≤0.02 mm; hardness must be appropriate.

Pyrophyllite roasting temperature and duration must be controlled to ensure proper pressure transmission and prevent moisture-related explosions.

Conductive steel rings must be rust-free, crack-free, stored dry, and show no blueing (oxidation) after baking.

4.Equipment Requirements
The press must have precise adjustment capability, no leaks, and synchronism/neutrality deviation ≤0.2 mm.

5.Operational Requirements
During assembly:

Inspect pyrophyllite for cracks/impurities and verify correct orientation of thin/thick steel discs.

Clean all six anvil surfaces before installation to avoid crushing or electrical discharge.

Ensure all four sides of each anvil are properly aligned to prevent failure/explosion.

Check cylinder movement: fixed cylinders must not misoperate; moving cylinders must pause at position.

Maintain pressure for ≥1 minute after heating stops to prevent rupture during pressure release.
