Tube Roll Former Downpipe Roll Forming Machine With Double Head Decoiler
The product is matched special equipment for welded pipe production enterprise. It has many advantages, such as rapid Zinc supplementation, high working efficiency, low energy consumption, long work time and can be suitable for kinds of environment and so on. At the same time, it solves the problems of Zinc supplementation for thick wall welding tubes, square tubes, industry type welding which the other similar products can not solve. It is the domestic only professional zinc spraying welded pipe special equipment.
(2) Arc spraying principle
Principle:Two sprayed Zinc wires do self-consumption electrode, and then arc which burns on the end of the wire material melts the wire which is sent into equably. Then through the compressed air, atomize the melting wire material to small particles that uniformly distribute and gush to workpiece stroke coating. When spraying, it needs to intersect a certain angle (usually 30-60°). Continuous sent two zinc wire respectively connects the positive and negative of the power. The end of the wire contacts the striking of arc, under the action of the power supply, Arc keep stable combustion, and at the back of the Arc occurrence point, let the melting wire atomize to particles through high-speed compressed air, and then spray into the base material surface which is after pretreatment, finally form the coating.
Spraying efficiency is high,operation is easy and safe
Bond strength of the coating and base material is high.
Deposition rate is high,spray deposition rates is more than 78%
Wire feed rate is accordant and stable, than can ensure fast, reliable of the striking of arc.
The machine can work continuously and stably for long time.
The equipments is specially suitable for machine unit for high-frequency straight seam welded pipe to spray for the welding line
Before the spraying job, the users must thorough reading the whole equipment specifications, and clear up the construction site and then reasonably decorate good equipment position, pay attention to take shelter from rain and proof dust.
