PURPOSE:To improve abrasion resistance, thermal cracking resistance, thermal fatigue resistance and corrosion resistance by affixing a coating layer of carbon fiber material on the contact surface of a mold copper plate such as Cu-Cr alloy with slab by the use of an adhesive agent. CONSTITUTION:The surface 1a of a mold copper plate 1 such as Cu-Cr alloy to be put in contact with a slab is affixed with a coating layer 4 composed of carbon fiber material to a thickness around 1mm. by way of an inorganic adhesive agent 5. It is desirable to use the adhesive agent of about 100-1,300 deg.C in heat resistance. With this method, even if part of the coating layer breaks, only required is to mend that portion alone. In addition, the surface of the mold copper plate is reinforced with carbon fiber material and therefore the rigidity becomes higher and thermal deformations do not occur at all. |
