Embodiment 1

[0026] These raw materials are weighed according to the mass percentage of 1% zinc, 2% tin, 23% bismuth, 0.5% antimony, 0.4% silicon carbide, 0.4% aluminum oxide and the balance of copper.

[0027] 1) Put copper, tin, zinc and antimony in a power frequency electric furnace according to the ratio, heat to 1200°C and completely melt, then keep warm to 1050°C;

[0028] 2) After the fully melted alloy liquid is fully stirred with a graphite tool, cover it with high-purity graphite with a thickness of 3 cm, and keep it warm; prevent the copper alloy water from oxidizing by covering the high-purity graphite, which will affect product quality.

[0029] 3) After 1 hour of holding time, the copper alloy water in the furnace is sampled 3 times by a Spike direct-reading spectrometer and the composition of the sample is detected to determine that the alloy composition is within the specified range;

[0030] 4) Place bismuth, silicon carbide, and alumina in a crucible furnace at the same t...

[0040] 1) Put copper, tin, zinc and antimony in a power frequency electric furnace according to the ratio, heat to 1200°C and completely melt, then keep warm to 1050°C;

[0041] 2) After fully stirring the molten alloy liquid with a graphite tool, cover it with high-purity graphite, with a thickness of 4cm, and keep it warm;

[0042] 3) After 1.2 hours of holding time, the copper alloy water in the furnace is sampled 4 times by a Spike direct-reading spectrometer and the sample is subjected to composition testing to determine that its alloy composition is within the specified range;

[0043] 4) Place bismuth, silicon carbide, and alumina in a crucible furnace at the same time for heating according to the proportion. The heating temperature is 370°C, and the heating time is 52 minutes. ...

Embodiment 3

[0052] These raw materials were weighed according to the mass percentage of 1.7% zinc, 2.7% tin, 2.7% bismuth, 0.8% antimony, 0.55% silicon carbide, 0.6% aluminum oxide and the balance copper.

[0053] 1) Put copper, tin, zinc and antimony in a power frequency electric furnace according to the ratio, heat to 1200°C and completely melt, then keep warm to 1050°C;

[0054] 2) After fully stirring the molten alloy liquid with a graphite tool, cover it with high-purity graphite, with a thickness of 4cm, and keep it warm;

[0055] 3) After 1.4 hours of holding time, the copper alloy water in the furnace is sampled 4 times by a Spike direct-reading spectrometer and the sample is subjected to composition testing to determine that its alloy composition is within the specified range;

[0056] 4) Put bismuth, silicon carbide, and alumina in a crucible furnace at the same time according to the proportion to heat, the heating temperature is 380°C, the heating time is 55min and stirred with...

Abstract

The invention discloses a continuous casting copper alloy material for an abrasion-resistant gear and a manufacturing method thereof. The continuous casting copper alloy material for the abrasion-resistant gear comprises, by mass: 1-2% of zinc, 2-3% of tin, 2-3% of bismuth, 0.5-1% of antimony, 0.4-0.6% of silicon carbide, 0.4-0.7% of aluminum oxide, and the balance copper. According to the continuous casting copper alloy material for the abrasion-resistant gear, the cutting performance and hardness of an alloy are further improved while the requirement for the environmental protection performance of the alloy is met on the premise that the cost is not increased; and the continuous casting copper alloy material is more suitable for abrasion-resistant spare parts under high temperature (400DEG C).

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a continuously cast copper alloy material for wear-resistant gears and a manufacturing method thereof. Background technique [0002] Existing tin bronze materials often add lead elements in order to achieve their chip-easy performance. With the obvious improvement of environmental protection awareness, bronze alloys containing lead elements can no longer meet the requirements of high-end markets at home and abroad. [0003] Therefore, there is an urgent need to design a copper alloy that is both environmentally friendly and has excellent cutting performance and hardness. Contents of the invention [0004] Aiming at the above defects in the prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a continuously cast copper alloy material for wear-resistant gears, which consists of the following components in mass percenta...
