Crystallization wheel is a key component in the copper rod and aluminum rod continuous casting and rolling production line. Its working principle is to pour the copper liquid and aluminum liquid which reach the specified temperature into the continuous rotating crystallization wheel groove, and then crystallize and form the casting billet under the continuous pouring of internal and external cooling water. And then the billet will enter into the rolling machine to be rolled into the rod meeting the requirements.
Common material for crystallization wheel: Pure copper, Chromium zirconium copper.

The crystallization wheel is a critical component in continuous casting and rolling lines. It solidifies molten copper or aluminum liquid into casting billets inside its rotating groove using a continuous internal and external water-cooling system.
Common materials include pure copper (Cu), Chromium Zirconium Copper (CuCrZr), and specialized copper alloys like CuNiSiCr, selected based on the required mechanical properties and thermal conductivity.
Standard diameters range from 1100mm up to 3800mm (including 1300mm, 1500mm, 1600mm, 1800mm, 2000mm, 2200mm, 2300mm, 2500mm, and 3100mm). Custom specifications can also be manufactured upon request.
Pure copper offers high conductivity (92% IACS) but lower softening temperatures. CuCrZr and CuNiSiCr alloys offer significantly higher softening temperatures (up to 650°C), tensile strength, and fatigue resistance, which helps prevent deformation during high-temperature casting.
A uniform cooling design ensures consistent solidification of the billet, prevents thermal cracking, reduces surface defects, and extends the overall service life of the wheel.
