AI Technical Summary

Technical Problem

In the existing solder powder production process, the reduction of the liquid level of the alloy liquid in the smelting furnace leads to a drop in the bottom pressure, and the flow rate of the alloy liquid is unstable. It requires manual addition of materials to keep the liquid level constant, but it is easy to cause the temperature of the alloy liquid to drop and segregate, and the agitating tool may introduce impurities.

Method used

A double-sealed furnace structure including a smelting furnace and a feeding furnace is designed. By filling the bottom of the furnace with nitrogen and top air pressure, the stable control of the bottom and top pressure of the alloy melt in the smelting furnace and the feeding furnace is achieved to ensure the stability and uniformity of the feeding system.

Benefits of technology

It realizes automatic and stable feeding of the feeding system during solder powder production, avoids temperature fluctuations and segregation problems caused by manual addition of materials, and ensures the stability of the atomization effect and the purification of the alloy liquid.
