Working principle of plasma atomization equipment: The metal raw material is introduced into the high temperature and high speed plasma formed by gas, so that metal material is melted and atomized or vaporized into steam under high temperature of plasma. Then atomized metal is rapidly cooled by gas quenching cooling technology and is solidified into micron or nano spherical powder materials.
Application
Plasma atomization powder manufacturing equipment is suitable for the preparation of the following high chemical purity, ultrafine and nano powder materials.
1. Metals: Cu, Fe, Al, Mo, W, Ni, Re, Ta, Ti and their alloys;
2. Oxides: Al2O3, MgO, TiO2, ZrO2, SiO2 ,etc..;
3. Carbides: WC, TiC, B4C, SiC etc..;
4. Nitrides: AiN, TiN, BN, Si3N4 etc...
By adjusting the process, different particle size ranges of powder can be produced.
Overview
Working principle of plasma atomization equipment: The metal raw material is introduced into the high temperature and high speed plasma formed by gas, so that metal material is melted and atomized or vaporized into steam under high temperature of plasma. Then atomized metal is rapidly cooled by gas quenching cooling technology and is solidified into micron or nano spherical powder materials.
Advantages
Plasma atomization equipment can prepare the vast majority of metals and their alloy powders on the market, and can meet the preparation requirements of many special alloy powders, such as high temperature ceramic powders, tungsten, tantalum and other metal powders with high melting point.
Plasma atomization powder manufacturing technology has the following advantages:
① The powder prepared by plasma atomization technology has high sphericity and composition segregation is not easy to occur.
②Based on high thermal energy input and steady flow atomization characteristics of plasma jet, it can effectively control the microscopic defects of powder such as hollow content and satellite sphere.
③ Plasma atomization technology uses plasma as heat source, the temperature is very high, theoretically it can prepare all metal powders with high melting point.
④ The melting and atomization processes are not in contact with the crucible, purity of powder is high, almost no doping. This technology is especially suitable for manufacturing high active powder materials.
⑤ Gas consumption and comprehensive energy consumption of this technology are small.
