It is applicable for spraying many kinds of metals and their alloy powder DF-3000 Ultrasonic Flame Spray EquipmentSince 1990th, our company has actively observed the latest development of world thermal spray industry. In order to adapt to market requirements, the new generation DF-3000 ultrasonic flame spray system was successfully launched in 2005. It adopts propane and Oxygen and burns them as heat source. It is applicable for spraying many kinds of metals and their alloy powder, especially for carbide (such as WC/Co and Cr3C2/Ni-Cr) and nitride powder. This equipment is characterized in advanced technology, excellent performance, reliable quality, easy operation, low price and excellent fabrication. The Compose of DF-3000 Ultrasonic Flame Spray EquipmentDF-3000 Ultrasonic flame spray gun;DF-3000 Powder feed device;DF-3000 Programmable automatic control platform;Cable and various pipelines.The Application of DF-3000 Ultrasonic Flam Spray EquipmentUltrasonic flame spray is characterized in high speed, low temperature, high deposition rate, high bonding strength, good reductibility and controllable coating composition. So it is extensively applied in metallurgy (such as roller and shaft fan blade), chemical engineering (valve, reaction vessel, pipeline, shaft), electric power (four tube in boiler, fan blade), petroleum (oil control pump, piston, hydraulic ram, shaft), Papermaking and printing (felt wrapped roll, roll coater, coating roll, dryer, batchoff roll and cutting machine) and general machine (shaft, dish or ball parts). Technical Performance Parameter List
