Embodiment Construction

[0017] The present invention will be further described below:

[0018] A method for manufacturing aluminum bronze, characterized in that it comprises the following manufacturing steps:

[0019] (1) Aluminum bronze is equipped with the following mass percentages: Al 10.2%, Sn 2.0-3.8%, Mn 2.0-2.3%, Fe0.03-0.06%, and the rest is Cu;

[0020] (2) Copper is loaded into the preheated crucible to make it melt rapidly;

[0021] (3) Continue heating. When the temperature reaches 1050°C, add phosphor copper and stir carefully to carry out deoxidation treatment. The percentage of the added phosphor copper in the total mass of the charge is 0.35%;

[0022] (4) Add the preheated aluminum-iron master alloy, pour it into the charge after melting completely, and stir;

[0023] (5) Raise the temperature to 1250°C, add a refining agent of 2.5% of the total mass of the charge, and stir to remove slag;

[0024] (6) Pre-furnace detection test, if the gas content is too high, use a bell jar to ...

Abstract

A method for manufacturing aluminum bronze, which belongs to the technical field of metal materials and heat treatment. The aluminum bronze is prepared according to the following mass percentages: Al 10.2%, Sn 2.0-3.8%, Mn 2.0-2.3%, Fe 0.03-0.06%, and the rest is Cu; The composition of the invention is novel, the production process is reasonable and clear, and the smelting process is easy to control; the invention makes the aluminum bronze have better wear resistance, corrosion resistance and corrosion resistance by reasonably quenching and tempering the formed aluminum bronze. It has better mechanical properties and can be used to cast heavy-duty, corrosion-resistant and wear-resistant parts.

Description

technical field [0001] The invention belongs to the technical field of metal materials and heat treatment, and relates to a method for manufacturing nonferrous metals, in particular to a method for manufacturing aluminum bronze. Background technique [0002] Copper and its alloys have excellent chemical, physical and mechanical properties, and have good corrosion resistance in the atmosphere, fresh water, sea water and non-oxidizing acidic media, so they are often used as functional materials and structural materials, and are widely used in aviation and shipbuilding , electrical and other fields, its consumption is second only to aluminum alloy in non-ferrous alloy materials. [0003] Aluminum bronze has high strength and good wear resistance. It is often used in screws, nuts, copper sleeves, sealing rings, etc. with relatively high strength. Its most prominent feature is good wear resistance and can be strengthened by heat treatment. It has higher strength than tin bronze ...
