And S5, cooling and collecting powder after atomization is finished.
After atomization, the silver powder particles are cooled at the bottom of the atomization chamber, and then the silver powder is collected through the cyclone separation system.
Further, before performing cooling in step S5, the method further includes:
and S50, reducing the pressure of the atomizing gas, and stopping introducing the atomizing gas after continuously purging for a period of time.
Specifically, after atomization is finished, a smelting and tundish heat-insulating power supply is closed, the pressure of atomized gas is reduced, and purging is continued for a period of time (such as 30 seconds). This ensures the completeness of atomization and allows the local region of the atomization chamber to be cleaned.
The cooling process can be through water circulative cooling's mode, and the cooling time goes on according to concrete demand, if the smelting furnace survives the liquation, then need increase the cooling time to avoid producing the damage to the coil.
Compared with the prior art, in the process of the silver powder manufacturing method, the cooling time of the liquid drops is prolonged by pre-increasing the environment temperature in the atomizing chamber, so that the liquid drops are spheroidized for a longer time, the finally cooled silver powder particles have better sphericity (roundness), and the product quality of the silver powder particles is improved.
