R6 100 × 100 × 900 mm Copper Mould Tube
The R6 100 × 100 × 900 mm copper mould tube is designed for billet continuous casting in steel plants. With a 100 × 100 mm square section, 900 mm length and R6000 mm casting radius, this copper mould tube provides efficient heat transfer and reliable dimensional stability during casting.
The tube is manufactured according to the customer's caster requirements and can be supplied with different copper grades, internal taper designs and surface coatings. Copper mould tubes are a critical component of the continuous casting mould, where rapid heat transfer forms a stable solid shell around the molten steel.
This size suits square billet casters on curved (R6000 mm) machines. The 100 × 100 mm internal section forms the required billet, and the 900 mm tube length provides the mould working length. We manufacture to your existing mould drawing, caster model and operating parameters.
Copper Grades for 100 × 100 mm Mould Tube
The 100 × 100 mm copper mould tube can be manufactured in different copper alloys according to casting speed, operating temperature, cooling conditions and required mould life.
Cu-DHP Copper
Cu-DHP is widely used for billet copper mould tubes because it combines good thermal conductivity, suitable mechanical strength and good manufacturing performance. It is the common choice for conventional billet casting.
CuAg Copper
CuAg0.1 provides higher resistance to thermal softening than standard DHP copper. Consider it for higher casting temperatures, higher casting speeds or more demanding operating conditions.
CuCrZr Copper
CuCrZr provides significantly higher high-temperature strength and resistance to deformation. It suits demanding applications where thermal stability and mould service life matter most.
Hard Chrome Plated Inner Surface
The inner working surface is supplied with hard chromium plating to improve wear resistance and protect the copper during casting.
- Hard chrome plating, our standard 0.08–0.12 mm
- Precision-machined and polished inner surface
- Suitable for continuous billet casting
- Other coating thicknesses and Ni-Cr on request
Internal Taper Design
The steel shell contracts as it moves through the mould, so the tube's internal profile must follow that shrinkage. We machine the taper to your caster parameters rather than one fixed profile for every application.
- Single taper
- Multi-taper
- Parabolic taper
- Convex taper
- Custom taper to drawing
Quality Control
Each tube is inspected throughout manufacturing for dimensional accuracy and surface quality. The inspection report ships with the tube.
