Embodiment 1

[0010] The CuNi2Si nickel-silicon bronze alloy plate of Y state 2X600X85.14mm is produced by rolling, and the process method adopts:

[0011] Melting and casting: Nickel-silicon bronze material components are weighed separately by weight: copper balance, nickel 1.6-3.4%, silicon 0.15-1.1%, manganese ≤ 1.0%, iron ≤ 0.6%, and unavoidable impurities ≤ 0.3% are weighed separately The ingredients are put into the smelting furnace one after another, and cast into ingots;

[0012] Heating: use a heating furnace to heat the ingot, heating temperature: 850-980°C, holding time: 2-3h;

[0013] Hot-rolling and quenching: use a hot-rolling mill to carry out billet hot-rolling on the heated ingot, and use normal temperature water to quench on-line for solid solution treatment, rolling rate: 90-95%;

[0014] Face milling: double-sided milling is used to mill the hot-rolled slab;

[0015] Cold rolling: the first cold rolling is carried out on the milled slab by the rough rolling mill, the r...

Embodiment 2

[0022] The CuNi2Si alloy bar of M state φ18X3000mm is produced by extrusion and stretching, and the process method adopts:

[0023] Melting and casting: Nickel-silicon bronze material components are weighed separately by weight. Ingredients: copper balance, nickel 1.6-3.4%, silicon 0.15-1.1%, manganese ≤ 1.0%, iron ≤ 0.6% and unavoidable impurities ≤ 0.3%, respectively The weight is successively put into the smelting furnace and melted into ingots;

[0024] Heating: use induction heating furnace to heat the ingot, heating temperature: 850~900℃, heating time: 3~6min;

[0025] Extrusion: use hydraulic press to extrude the heated ingot into billet, extrusion ratio: 26-45;

[0026] Stretching: use a stretching machine to perform the first stretching process on the extruded billet, and the stretching processing rate: 38-45%;

[0027] Annealing: Use an annealing furnace to perform intermediate annealing on the stretched billet, annealing temperature: 650℃~700℃, annealing time: 2~4...

Abstract

The invention discloses nickel, silicon and bronze alloy materials and a technology for processing the same, wherein the nickel, silicon and bronze alloy materials are alloys taking the Cu-Ni-Si component system as a base, which are formed by main alloys of bronze, nickel and silicon, microelements such as manganese and iron and impurities; different materials are made by the rolling mill processing method and the extrusion-extension processing method; the nickel, silicon and bronze alloy materials processed by the invention have the advantages of low cost, simple process, high technical level and good quality; moreover, as for plates and bands made by the rolling mill processing method, the mechanical property reaches between Rm480 and 580 MPa, the Vickers hardness reaches between HV100 and 150, and A is more than or equal to 10 percent; as for bars or section bars made by the extrusion-extension processing method, the mechanical property is more than or equal to 240 MPa, the Vickers hardness reaches between HV100 and 150, and A is more than or equal to 20 percent.

Description

technical field [0001] The invention relates to a nonferrous metal processing technology, in particular to a nickel-silicon bronze alloy material and a processing technology thereof. Background technique [0002] Nickel-silicon bronze alloy belongs to high-strength wear-resistant bronze due to its high strength, excellent corrosion resistance, wear resistance, formability, stress relaxation resistance and hot and cold processing performance, and is mainly used in aviation, military bearings, ship components, Electrified railway devices and other fields. In recent years, with the sustained and rapid growth of my country's economy, especially the rapid development of industries such as electromechanical manufacturing, ships, and electrified railways, the demand for nickel-silicon bronze materials has grown steadily year by year. In particular, nickel-silicon bronze materials used for integral suspension and positioning clamps used in electrified railways need to be imported i...
