Copper moulds have played an important role in the development of the continuous casting process .Their function is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification. The mould must exhibit excellent thermal conductivity, be resistant for thermal erosion, and be resistant to distortion from thermal stress.

Mould material: The tough working condition of copper mould tube requires its material with excellent tensile strength, enough hardness, low elongation & good thermal conductivity. After many years experiment in our Lab & steel mills, now we are manufacturing copper mould tube with widely accepted material as : Tp2, CU-Ag0.1 & Cu-Cr-Zr.

Typical coatings are : Cr, Ni, Cr-Ni, Ni-Fe, Ni-Co

Square copper mould tube specification:

Size: 60x60~700x700, Radius: 4000-17000,Length: 700-1000, Taper deign: single taper, double

Tapers, triple tapers, quadruple tapers, parabolic taper,double parabolic taper, and convex.
