A High-Quality Casting Begins with the Right Mould

In today’s fast-paced steelmaking industry, continuous casting equipment must do more than simply function — it must perform with efficiency, durability, and precision.

As the core of the continuous casting process, the mould plays a decisive role in determining slab quality, casting stability, and production yield.

And within this vital component, the Copper Mould Tube stands as the first line of defense against defects — what may seem like just a copper pipe is, in fact, the key to a stable casting line.

We Understand the Challenges You Face:
1.Surface segregation and corner cracks leading to downstream rejection

2.Frequent tube replacements causing excessive downtime and cost

3.Poor compatibility with existing casters, limiting casting potential

4.Lack of performance monitoring and predictability in maintenance

What We Deliver Is More Than Just a “Tube”
1.Custom-Engineered for Your Caster
Whether you run a curved, straight, or bow-type caster, JISTEEL offers tailored mould tubes for any section shape, arc radius, cooling slot, or coating type.

2.Materials That Last, Performance You Can Trust
Using high-purity Cu-Ag alloy and advanced Cr / Ni-Cr plating, our tubes achieve superior thermal conductivity, longer life, and outstanding resistance to fatigue and corrosion.

3.Full Lifecycle Support, from Design to Operation
From product selection and drawing design to on-site commissioning and data monitoring, JISTEEL delivers a complete casting mould solution, not just a product.

Real Data, Real Results
