Vacuum Induction Melting Inert Gas Atomization Powder Production Equipment
Technical principle: Under vacuum or inert gas atmosphere, molten metal is poured into insulation tundish, then flows through the draft tube, eventually crushed and atomized into extremely tiny droplets by a high-pressure gas atomizer, forming spherical or sub-spherical powder by the effect of surface tension during the process of cooling, the powder is collected by containers connected to atomizing tower and gas-powder separation system.
Equipment overview: This equipment mainly comprised of vacuum melting furnace, insulation tundish(single or double), powder collection system, atomizing tower with vacuum insulation valve, tight coupling supersonic gas atomizer, vacuum system, high-pressure gas supplying and controlling system, water cooling system, electrical control system, etc.
Superiorities and features: 1. Online monitoring of oxygen content of gas during atomization, which greatly helps control the oxygen content of the powder 2. Video surveillance function available on critical systems like atomizing towers. 3. With the application of key technology-tight coupling supersonic gas atomizer, it can produce powders with a high proportion of superfine size but consume less inert gas, in the meantime decreasing pore quantity in particle. 4. Well-designed fast cooling system and atomizing tower, decrease satellite powder. 5. Powder size (distribution) and shape are adjustable by changing process parameters.
