Steel mills run on tight schedules and even tighter margins. When a roll fails, it’s more than just an inconvenience—it’s a chain reaction of delays, missed quotas, and lost profits.
That’s where centrifugally cast rolls come in, built for durability and to keep operations running smoothly. But success in steel mills isn’t just about having the right rolls—it’s about partnering with a foundry that understands the industry’s challenges and helps you stay ahead of them.
In this post, Steph Gallagher, Spuncast’s Business Development Manager with over a decade of experience in the steel mill industry, explains how three roll types produced by Spuncast have proven to boost efficiency, extend equipment life, and give steel mill operations an edge.
Why centrifugal casting matters in today’s steel industry
As the steel industry pushes for high-performance materials, mills need components that can withstand extreme conditions while maintaining reliability. Centrifugally cast rolls offer the durability and customization to meet these demands.
“Spuncast primarily serves machine shops and maintenance businesses within the steel mill industry,” says Gallagher. “But we also work directly with steel mills, providing tailored solutions to their unique needs.”
Gallagher points out that steel mill professionals are drawn to centrifugal casting because it offers flexibility in sizing and hardness. This versatility allows Spuncast to tackle a wide range of challenges, whether it’s maintaining legacy equipment or optimizing cutting-edge systems.
Emerging trends in steel mill technologies
As many steel mills evolve with modern manufacturing trends, automation and digitization are becoming standard. These advancements enhance efficiency and predictive maintenance, and centrifugal casting aligns perfectly by delivering precise, high-quality components that help mills stay competitive.
“Old-school” steel mills still rely on familiar parts and specs, but both traditional and modern mills are increasingly focused on sustainability.
Gallagher notes a growing investment in energy-efficient technologies and the use of recycled materials. Centrifugal casting supports this trend by minimizing waste and improving material efficiency, making it an ideal choice for future-focused operations.
3 critical steel mill rolls & the advantages of centrifugal casting
Centrifugal casting is particularly effective for steel mill machines requiring caster, table, and sink rolls. Each roll type has specific requirements and encounters distinct environmental and operational conditions during production.
- Caster Rolls:
- Tough Conditions: Positioned at the start of the steel production line, caster rolls endure extreme heat and pressure during slab formation.
- Spuncast’s Advantage: Using CA40 material, Spuncast’s caster rolls offer exceptional wear resistance and heat tolerance, ensuring they perform reliably under intense conditions.
- Table Rolls:
- Heavy Loads: Mid-process table rolls are responsible for handling heavy slabs while maintaining precise dimensions and enduring constant wear.
- Spuncast’s Advantage: Spuncast customizes table rolls with heat-treated centrifugal castings to match each mill’s specific wear and load requirements, enhancing durability and precision.
- Sink Rolls:
- Corrosive Environments: Sink rolls are exposed to chemicals during galvanizing, making corrosion resistance and surface integrity critical.
- Spuncast’s Advantage: With carefully selected alloys, Spuncast’s sink rolls resist chemical degradation and maintain smooth, defect-free surfaces, even in the harshest environments.
The key advantages of centrifugally cast parts
Centrifugal casting offers several advantages, particularly for components in the demanding environment of steel mills:
- Superior Material Density: Centrifugally cast parts benefit from high material density, which results in fewer defects like porosity or inclusions. It also increases strength and durability to withstand heavy loads and constant wear.
- Customizable Alloy Properties: Centrifugal casting allows for precise control over the material properties, making it possible to tailor the hardness and wear resistance of parts like rolls to meet specific operational demands.
- Cost Efficiency: Centrifugal casting reduces the need for additional machining and material wastage by producing rolls with the needed material properties. Often, multiple parts can be produced from a single casting, keeping costs competitive.
- Longer Lifespan: Centrifugally cast parts, particularly those made with CA40 material, often last significantly longer than their counterparts. This extended lifespan reduces downtime and maintenance costs.
“Our steel mill customers want a product that won’t fail prematurely, and our centrifugal casting process ensures they get the durability they need.”

Spuncast success stories in the steel mill industry
Spuncast’s commitment to quality and innovation is demonstrated through:
- Customization options: Tailored to meet specific needs
- Domestic sourcing: Reduced lead times and reliable supply
- Expert support: Experienced team and technical assistance
- Innovation: Continuously exploring new materials and techniques
- Enhancing Performance in Steel Mills: Steel mills often struggle with frequent caster roll failures in their internationally sourced machines. Spuncast’s CA40 material rolls have proven to significantly outperform the original rolls supplied with the new machines, reducing replacement rates and minimizing downtime.
- Optimizing Roll Life in Machine Shops: When machine shops seek to extend roll life by increasing the roll’s outer diameter (OD), Spuncast can collaborate with them and create a solution that allows for an additional pass before replacement, enhancing the roll’s service life and reducing downtime.
- Ensuring Reliability for Maintenance Businesses: In the demanding environment of galvanizing, sink rolls often fail due to corrosion. Spuncast’s robust warranties and commitment to product quality ensure these customers receive durable replacements quickly.
Proven performance and strong relationships
Centrifugally cast parts are built to handle the demanding conditions of steel mills, offering enhanced durability and performance. Embracing this technology can lead to greater efficiency and a competitive edge.
However, Gallagher emphasizes that building strong connections is key. “I work to prove that we know what we’re talking about and can make their day easier and operations smoother,” she says.
By offering superior wear resistance, corrosion resistance, and long lifespans, Spuncast helps steel mills improve efficiency and reliability, aligning with the latest industry trends and demands.
