Embodiment Construction

[0019] The steps and characteristics of a high-precision complex nickel-nickel ternary alloy production process of the present invention are described in detail as follows in conjunction with the accompanying drawings.

[0020] Step 1: Cupronickel casting billet.

[0021] In this step, the nickel-copper horizontal continuous casting is carried out after the ingredients are smelted. Electromagnetic casting technology is used in the horizontal continuous casting of cupronickel to improve the inner quality of the billet. The so-called electromagnetic casting technology is in the stage of solidification of liquid metal into a solid state. When it is in solid-liquid fusion, the electromagnetic force is generated by the electromagnetic coil, and the electromagnetic field is applied to the metal to improve the flow of the metal and the distribution of the solute, and effectively eliminate the surface and interior of the ingot. Defects such as segregation can be eliminated to obtain ...

Abstract

The invention provides a high-precision complicated white copper alloy ternary alloy production technology which comprises the following steps of white copper blank casting, ingot cold machining and surface defect removing, wherein in the white copper blank casting step, horizontal continuous casting is conducted by adopting an electromagnetic casting technology, wherein the smelting temperature is 1,200-1,350 DEG C, and liquid copper is water-cooled; in the ingot cold machining step, rough rolling, annealing and intermediate rolling, annealing and finish rolling, and annealing are performed; and in the surface defect removing step, passivating, pickling and washing of a copper strip are performed, wherein the used passivator is benzotriazole, the concentration of a passivating liquid is 0.5-2.5 g/L, and the conductivity of pure water for washing is controlled to below 50 microseconds/cm. According to the high-precision complicated white copper alloy ternary alloy production technology, horizontal continuous casting is conducted, hot mills and heating furnaces are omitted, the production efficiency is high, and the energy consumption is low; the produced complicated white copper is high in corrosion resistance, tensile performance and elongation.

Description

technical field [0001] The invention relates to the technical field of alloy processing, in particular to a high-precision and complex copper-nickel ternary alloy production process. Background technique [0002] Pure copper plus nickel belongs to the binary alloy, called common cupronickel. This material has high strength, corrosion resistance, hardness, electrical resistance and pyroelectricity, and reduces the temperature coefficient of resistivity. Therefore, cupronickel has better mechanical properties than other copper alloys. , physical properties are exceptionally good, good ductility, high hardness, beautiful color, corrosion resistance, deep drawing performance, are widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical equipment, daily necessities, handicrafts and other fields, and are still important resistance and thermocouple alloys. [0003] On the basis of ordinary white copper, adding other elements, such as iron, manganese,...
