About LI ZHAO – Copper Mould Tube & CCM Spare Parts Manufacturer
ZHENG ZHOU LI ZHAO ELECTRIC FURNACE CO., LTD. is a China-based manufacturer and supplier of copper mould tubes, copper mould assemblies, mould water jackets, dummy bars, dummy bar heads and other continuous casting machine spare parts for billet and bloom casters.
About LI ZHAO
Our business supports steel billet, bloom and continuous casting operations with customized mould components manufactured according to customer drawings, caster dimensions and operating requirements. Engineering and production cover the complete mould section, from the copper mould tube and cooling water jacket to the dummy bar system and related mechanical components.
For customers who already have drawings, samples or an existing worn component, we provide OEM replacement and custom manufacturing based on the original dimensions and technical requirements.
The copper mould tube is the key heat-transfer component of a continuous casting machine, working with the water jacket to extract heat from the newly solidifying strand. We supply it in Cu-DHP, CuAg and CuCrZr, with the taper and coating configuration the caster requires.





Our Core Business: Continuous Casting Mould Components
We are not a general copper products supplier. Our manufacturing and this website are built around continuous casting mould components and CCM spare parts, so a buyer can move from an individual copper mould tube to a complete mould system or related replacement parts.
Copper Mould Tube
Square, rectangular and round tubes for billet and bloom casting, with customized radius, section, length, wall, taper and coating.
Copper Mould Assembly
Complete assemblies integrating tube, water jacket, flanges, seals and cooling connections.
Mould Water Jacket
Customized jackets matched to the copper tube and the caster cooling requirements.
Copper Materials
Cu-DHP / TP2, CuAg0.1 and CuCrZr grades for different casting conditions.
Dummy Bar
Rigid and chain-type dummy bar systems for continuous casting machines.
Dummy Bar Head
Square, rectangular and round heads manufactured to mould section and caster requirements.
Specifications
Full size tables for square, rectangular and round tubes in mm and inch.
CCM Spare Parts
Customized flanges, seals, connecting components and other metallurgical spare parts.
Copper Mould Tube Manufacturing
Our main product is the copper mould tube for continuous casting. We manufacture square, rectangular and round tubes to customer requirements. Typical technical parameters: casting radius, billet or bloom section, tube length, wall thickness, copper grade, internal taper, chrome or alloy coating, cooling design, caster model and quantity.
Cu-DHP / TP2
Phosphorus-deoxidized copper for conventional continuous casting.
CuAg0.1
Silver-bearing copper where higher thermal stability and resistance to high-temperature softening are required.
CuCrZr
Chromium-zirconium copper for higher mechanical strength and thermal stability.
Material selection depends on casting conditions, operating temperature and required service performance; see copper materials.
R4, R5, R6 and R9 Copper Mould Tubes
We manufacture for different casting radii: R4 / 4000 mm, R5 / 5000 mm, R6 / 6000 mm, R9 / 9000 mm and customized radii to drawing. Typical billet sections: 100 × 100, 120 × 120, 130 × 130, 150 × 150, 160 × 160 mm, rectangular, round and other customized sections.
Radius, section and internal geometry must correspond to the continuous casting machine design rather than being selected independently. This site therefore provides separate product pages by casting radius and by exact specification, such as 100 × 100 × 900 R6 and 130 × 130 × 900 R6.

Made to Drawing – Custom Copper Mould Tube Manufacturing
Have a drawing? Send it to us. This is one of the most important services we provide. Customers can send a PDF, DWG or STEP drawing, an existing mould tube, old tube photographs, dimensional measurements or the caster model. Our engineering team reviews:
before preparing a quotation. For replacement projects a completely new drawing is not always needed: an existing tube, photographs and accurate measurements are a valid starting point for engineering review.
Copper Mould Tube Repair and Re-Plating
A worn tube does not automatically have to be replaced. Depending on its condition, a used copper mould tube is evaluated for internal surface wear, taper condition, wall thickness, deformation, cracks, chrome coating condition and machining allowance. Where technically suitable, the tube is re-machined and re-plated, giving maintenance teams a second option when evaluating replacement costs. See Repair or Replace?.

Copper Mould Assembly and Water Jacket
For customers who need more than the tube, we manufacture complete copper mould assemblies:
The water jacket is designed to work with the copper tube and the caster's cooling system, so tube and jacket come from the same drawing set and dimensional mismatch at installation is avoided. See assemblies and water jackets.
Dummy Bars and Dummy Bar Heads
Dummy bar components are manufactured for square, rectangular and round billet casters, bloom casters and customized designs; heads for square, rectangular and round sections. We accept drawings, samples and dimensional information for replacement manufacturing. See dummy bars and dummy bar heads.
Engineering and Technical Support
When reviewing a copper mould tube inquiry, we do not look only at the outside dimensions. The technical review covers casting section, casting radius, tube length, wall thickness, internal taper, copper grade, plating, cooling arrangement, installation dimensions and the existing mould design, so the supplied component corresponds to the customer's actual equipment. Reference values are on the technical data page.


Manufacturing and Quality Control
Drawing review
Drawings and existing samples are reviewed before production.
Material selection
Copper grade and other materials confirmed against requirements.
CNC machining
Critical dimensions and internal geometry machined to the approved drawing.
Taper & radius inspection
Geometry checked against the specified caster dimensions on a CMM.
Surface treatment
Hard chrome or other specified coating applied to the product requirement.
Final inspection
Dimensional and surface inspection with report before shipment.
Quality Is Defined by the Drawing
For continuous casting spare parts, "standard product" does not always mean "correct product". A tube with the same nominal section can still differ in radius, length, wall thickness, taper, internal geometry, coating and connection dimensions. Our approach: confirm the drawing and operating requirements first, then manufacture. This matters most for OEM replacement and maintenance projects.
