Radio Frequency Plasma Balling Metal Powder Manufacturing Process With High Speed

1~3KG Radio-frequency Plasma Powder Balling Metal Powder Atomization Equipment For Ti , W

Overview

Radio-frequency plasma torch possesses high energy density, strong heating strength, and its plasma arc is huge. Due to no electrodes available, it can not generate contamination to products caused by electrode evaporation.

The principle of radio-frequency plasma powder balling technology refers to that inert gas (like argon) is ionized under the effect of high-frequency power supply and formed as stable high temperature inert-gas plasma; and the irregular raw powder is sprayed by carrier gas (nitrogen) into the plasma through powder feeding device, and these powder particles absorb large amount of heat in high temperature plasma and their surfaces are melted rapidly; then these melted powder are sent into reaction device by extremely high speed, and fast cooling under inert gas environment. Consequently, they are cooled down and solidified into spherical powder by surface tension; furthermore, they are sent into material gathering room.

Features

• High heating temperature, fast cooling speed, no electrode contamination;
• Reaction materials are dynamically dispersed in plasma torch, in this way it can avoid the accumulation and growth of powders, and it is applied to melting and balling of powder particles;
• Suitable for producing tungsten, molybdenum, Ti, W, WC, aluminum oxide, silicon oxide, zirconium oxide and other refractory metal and oxide powder
• Regular shape, high spheroidization, smooth surface and good flowability; and the powder density and bulk density increased

Core Module Structure Technology

Radio-frequency plasma torch balling powder producing equipment is constructed with following seven components and peripheral components:

• Radio-frequency plasma torch;
• Radio-frequency plasma power supply;
• Gas supplying and powder feeding system;
• Reaction room, collection room and support;
• Vacuum pumping system;
• Electric controlling and measuring system;
• Cooling water unit.

Radio-frequency plasma torch:

The core technology of the whole set of equipment belongs to the technology of independent intellectual property rights. Ceramic constraining pipe and divergent nozzles are adopted. The equipment can run under inert gas, reduction and oxidation atmosphere environment.

High-frequency plasma power supply:

Power 100kW, frequency 3.0±0.5MHz.

Gas supply and powder feeding system:

Powder feeding device adopts an imported product made by Canadian TEKNA Company, and it sends powder material into plasma torch. The diameters of powder particles are 10-200µm; gas supplying system applies precise float flowmeter (4 road), providing working gas (argon) for the torch. Reaction room, gathering room and support: reaction room and gathering room utilize double-layer water cooling structure, and they are made of stainless steel, entirely adopting vacuum sealing pattern; the support is spray-painted by carbon steel, partial materials are aluminum alloy which are strong, hard, steady and safe.

Pumping system:

It is equipped with water-circulating vacuum pump + mechanical pump + roots pump + regulating valve + pipes + corrugated bellows, and switched to maintain the required negative pressure for system starting and operating. Extreme vacuum is 8 x 10^-2Pa.c
