operating conditions

Built for the Conditions That Challenge Thermal Processing Equipment

Heat treatment and thermal processing components must perform through repeated heating cycles while supporting loads, maintaining dimensional stability, and withstanding the surrounding process environment.

Sustained High Temperatures

Continuous exposure to elevated temperatures can cause conventional materials to lose strength, deform, oxidize, or degrade over time.

Thermal Cycling

Heating and cooling cycles create thermal stress that can contribute to cracking, distortion, and premature component failure.

Rapid Temperature Changes

Batch operations and changing process conditions can expose components to sudden temperature changes that challenge materials with poor thermal shock resistance.

Process Atmospheres

Oxidizing, reducing, acidic, alkaline, and other reactive atmospheres can affect component performance and material life.

Mechanical Loading

Beams, posts, setters, and other structural components must support loads while operating at elevated temperatures over repeated production cycles.

WHY SIlicon carbide

Material Performance That Holds Up Under Heat

Large Monolithic Shapes

SCP manufactures complex and large monolithic silicon carbide components, reducing the number of seams and joints required in multi-piece assemblies.

Thermal Shock Resistance

Silicon carbide's thermal shock resistance helps it perform through repeated and rapid temperature changes that can damage less suitable materials.

Strength at Temperature

SCProbond™ materials maintain the properties required for structural and load-bearing components operating at elevated temperatures.

Wear Resistance

Where components experience abrasive contact, silicon carbide's high hardness provides additional resistance to surface wear.

High-Temperature Capability

SCProbond™ N can be used in continuous service at temperatures > 1525°C under appropriate operating conditions, making it suitable for demanding industrial thermal applications.

Chemical & Atmospheric Resistance

Silicon carbide provides resistance to many acidic, alkaline, and reactive process environments where chemical attack or oxidation can shorten component life.

Material selection depends on the specific temperature, atmosphere, loading, geometry, and cycle requirements.

Applications

Case studies

Proven Performance

Silicon carbide for thermal processing in a furnace lining.

Limestone Processing

In abrasive limestone processing environments, SCProbond™ silicon carbide liners significantly extended the service life of cyclones, chutes, pumps, and screw conveyors, reducing wear-related downtime and maintenance costs.

Corrugated silicon carbide for thermal processing

Trona Refining Cutter Blocks

SCProbond™ nitride bonded silicon carbide cutter blocks outperformed gas nitrided steel, tungsten carbide coatings, and white cast iron, showing only 40% wear after 10.9 million pounds processed and remaining in service beyond 16 million pounds.

Before and after silicon carbide for thermal processing.

Limestone Screw Conveyor

A shaft liner remains wear free after two years in service, while custom contoured screw conveyor flight plates have preserved diameter and performance for over 20 months after processing nearly 80,000 tons of abrasive material.

The SCP Difference

More Than a Component Supplier

When a wear problem affects production, you need more than a material recommendation. SCP provides engineering support, custom manufacturing, and direct customer advocacy from application review through delivery.

Application-Focused Support

SCP considers operating conditions, component geometry, wear mechanisms, temperature, and chemical exposure when evaluating a material and component solution.

Reliable Delivery

> 95% on-time delivery helps customers plan maintenance and replacement requirements.

In-House Patterning & Tooling

Patterns and tooling are developed and maintained in-house, giving SCP greater control over precision, revisions, and production scheduling.

Customer Advocate

Each customer receives a customer advocate who serves as a single point of contact for any and all questions through every stage.

Custom & Complex Geometries

SCP has manufactured more than 4,000 unique shapes, including complex and large monolithic components.

Easier Repeat Orders

Your proprietary tooling remains with SCP, creating an established manufacturing foundation for future replacement and repeat orders.
