Production Process Of Atomized Bronze Powder

Production Process Of Atomized Bronze Powder

Bronze powder is an important raw material for the production and use of powder metallurgy products. Production of international industrial bronze powder began at 20 century. The production methods used at that time are restoring copper element and electrolysis. After 1950s, there are new production methods for bronze powder: replacement precipitation and hydrometallurgy new wrinkle. Then the atomization rote emerges.
In 1958, China began the trial of bronze powder ( FCu 663 ). It was about the production test of electrolytic bronze powder at that time. In the mid - 1960s, electrolytic bronze powder trial to be efficacious and put small cartel production. The mid - 1970s, China has proverbial a production line of the first electrolytic bronze powder. In the 1980s and 1990s, with the rapid development of China ' s national economy, the bronze powder was substantially major. In order to meet market demand, the number of immense enterprises by tapping the quiescent of innovation and technological transformation, the bronze powder production - community. In the meantime, have received and developed more than l0 bronze powder manufacturers, National bronze powder production capacity of about 4000t, annual average production is about 1400t.
Alternative to electrolysis in the production of bronze powder, when the devaluation of the atomization milling mode. Practice has proved that a single atomization production of bronze powder bulk density and empty-handed formability drawback in practical applications can not be replaced by electrolytic bronze powder. Accordingly, the use of water atomization, twofold with the subsequent treatment process, not unlike as redox developed to meet the environmental needs of low bulk density of bronze powder.
Industrialization atomized bronze powder production wise by gas atomization and water atomization channels. Production practice proves that the production effect of water atomization gas atomization. The twin particle size and particle size composition of the water atomization and gas atomization bronze powder, the twin follow - up treatment conditions, the heat effect and the finished product bulk density is different. Study its causes, water atomized powder particle shape irregular powder than aerosolization, and and so more supportive to speed up the scintillation percentage.
The embers process has great influence on the production of high - performance and low loose density bronze powders. It is ring in that in phlogiston process, the luminosity time and luminosity temperatures have a great influence on the flames effect of metal powder. In original, in the identical rapid oxidation time and phlogiston temperature, flare is particularly affected the warmth effect. Warmth proceeding is divided into static and go-getter in two ways. Static holocaust, the flames proportion of the bronze powder is very unruffled, and addicted to agglomeration; strenuous glow is not, so the inferno effect is very good. Relating as beneath in 5000C / 3h kind, static charring of the bronze powder energetic holocaust content is 7. 5 %. The bulk density is 3. 80g / cm3. Dynamic combustion content of bronze powder oxygen is 18. 7 % and bulk density is 2. 32g / cm3.
AOR arrangement of production of bronze powder, due to the microscopic shape of irregular, low oxygen content, good formability, process performance and stability, and it could replace the electrolytic copper powder. Lack a higher friction material used in packed - based products and green strength carbon copy products. Several well - known powder metallurgy and electric copy enterprises have use the powders in great - scale. It is plant that the effect is very nice.
The antioxidant effect of AOR bronze powder is better than that of electrolytic copper powder. Unbefitting the alike conditions, the antioxidant effect of the AOR procedure bronze powder is 2 times than electrolytic copper powders. This is particularly important to manufacturers of diamond tools. Seeing these enterprises use a small amount bronze powder every time, thereupon requiring a long shelf life of the powder.
