Problems solved by technology

[0002] With the development of continuous casting technology, the requirements for the performance of copper alloy materials are getting higher and higher. Because it is difficult to balance the electrical conductivity and material strength, the strength and hardness of beryllium nickel copper are relatively high at room temperature, and the electrical conductivity and thermal conductivity are somewhat biased. Low, so that the mold copper plate of beryllium-nickel-copper has a relatively high temperature on the hot surface during continuous casting. Usually, with the increase of the temperature environment, the strength and hardness of the material decrease relatively, and the wear resistance also decreases relatively at high temperature. , so that beryllium-nickel-copper cannot be applied in the newly developed ultra-high-speed ESP continuous casting technology

Abstract

The invention provides a base metal of a narrow-surface copper plate of an ESP continuous casting crystallizer and a processing method thereof and the narrow-surface copper plate of the ESP continuouscasting crystallizer, and belongs to the technical field of copper alloys. The base metal comprises the following chemical components: 97.05-98.66wt%of Cu, 1.0-2.2wt% of Ni, 0.12-0.3wt% of Zr, 0.2-0.4wt% of Be, and 0.02-0.05wt% of Mg. The base metal is high in electricity and heat conducting performances. The processing method of the base metal of the narrow-surface copper plate of the ESP continuous casting crystallizer comprises the steps of mixing corresponding alloy materials, and then sequentially carrying out vacuum smelting, vacuum ingot casting, thermal forging, solution treatment, cooling and hardening, and aging treatment. The processing method is simple; the strength of the produced material is the same as that of beryllium copper nickel and is high in electricity and heat conducting performances. The temperature of the heating surface of the copper plate prepared through the base metal in continuous casting is greatly decreased, and the copper metal is high in intensity, high in hardness and high in corrosion resistance under low temperature.
