Abstract

The invention discloses a continuous casting crystallizer copper plate electroplating nickel-cobalt-manganese alloy plating layer, and belongs to the technical field of surface treatment. The continuous casting crystallizer copper plate electroplating nickel-cobalt-manganese alloy plating layer comprises a crystallizer copper plate substrate, the surface of the crystallizer copper plate substrateis plated with a Ni-Co-Mn alloy layer, and the Ni-Co-Mn alloy layer contains Ni accounting for 95%-97% of the mass of the plating layer, Co accounting for 2%-4% of the mass of the plating layer and Mnaccounting for 0.1%-1% of the mass of the plating layer. The electroplating nickel-cobalt-manganese alloy plating layer is low in cost, high in hardness and elongation, excellent in high-temperaturecorrosion resistance and wear resistance and suitable for high-drawing-speed intensive-cooling continuous casting production, the cost is decreased by about 25% compared with a nickel-cobalt-iron electroplating layer, and the operation rate of a continuous casting machine can be increased by about 30%.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a nickel-cobalt-manganese alloy coating layer electroplated on a copper plate of a continuous casting crystallizer and a preparation process thereof. Background technique [0002] The continuous casting mold is the core equipment of the whole continuous casting production, its quality directly affects the quality of the casting slab and the operating efficiency of the continuous casting machine. However, if the performance of the mold develops in the direction of high casting speed, high mechanical strength, good thermal conductivity, high hardness, high wear resistance and corrosion resistance, the surface of the mold must be treated. Among the many existing crystallizer surface treatment technologies, electroplating technology is still the one with mature technology, less equipment investment, low production cost and high raw material utilization rate.
