Embodiment 1

[0014] A kind of production method of the copper-tin 33 alloy powder that is used for glass grinding tool, concrete steps are as follows:

[0015] (1) The raw materials are copper plates with a copper content of 99.95% or more and tin ingots with a tin content of 99.95% or more, and in terms of weight percentage, the copper plate accounts for 66% and the tin ingot accounts for 34%;

[0016] (2) Add the specified copper plate during the heating process of the intermediate frequency furnace, and keep it warm after the temperature rises to 1400 ° C. After the copper plate in the intermediate frequency furnace is completely melted into copper metal liquid, then gradually add the specified tin ingots into the intermediate frequency furnace. The time is controlled at 10 minutes, and then kept warm for 5 minutes, so that the copper and tin metal liquids are completely mixed;

[0017] (3) Then turn on the high-pressure water pump, and the high-pressure water volume is controlled at 7m...

Embodiment 2

The time is controlled at 12 minutes, and then kept warm for 58 minutes, so that the copper and tin metal liquids are completely mixed;

[0024] (3) Then turn on the high-pressure water pump, and the high-pressure water volume is controlled at ...

Embodiment 3

[0028] A kind of production method of the copper-tin 33 alloy powder that is used for glass grinding tool, concrete steps are as follows:

[0029] (1) The raw materials are copper plates with a copper content of 99.95% or more and tin ingots with a tin content of 99.95% or more, and in terms of weight percentage, the copper plate accounts for 68% and the tin ingot accounts for 32%;

[0030] (2) Add the specified copper plate during the heating process of the intermediate frequency furnace, and keep it warm after the temperature is raised to 1500 ° C. After the copper plate in the intermediate frequency furnace is completely melted into copper metal liquid, the specified tin ingots are gradually added to the intermediate frequency furnace. The time is controlled at 5 minutes, and the temperature is kept for another 10 minutes, so that the copper and tin metal liquids are completely mixed;

Abstract

The invention discloses a method of producing a copper-tin 33 alloy powder for a glass grinding tool. The iron-cobalt-copper alloy powder is dendritic; in terms of weight percentage, the cobalt content accounts for 95-99%, and the chromium content accounts for 1-5%; the iron-cobalt-copper alloy powder has the fisher particle size of 1.0 to 1.2 micrometers; the oxygen content is less than 0.50%; and the apparent density is 0.4 to 0.6g / cm<3>. The yield of the method is more than 95%; the yield of the traditional atomization method is only 60-70%; the method can greatly reduce the energy consumption; the cobalt carbonate and the chromium carbide used as raw materials in the production process of the method are melted and cracked at a high temperature and the chemical components are decomposed, meanwhile crystals formed by mutual penetration have wide distribution of elements, uniform voidage and high degree of forming, and effectively improves the rupture strength and service life of theproduct, and the co-melting of the crystals with other metals is improved.
