Cnc plasma wear resistant cladding equipment
Introduction
To resolve the wear issues of scraper conveyor, we have made a lot of theoretical researches and underground tests, and succeeded in developing numerical controlled plasma cladding wear-resisting technologyâ?� and zrf-5c numerical controlled plasma central trough cladding machine toolâ?�. The technology can make the base materials and alloy powder melt synchronously instantlyïre-melt , and produce the wear-resisting strengthened layer in original position. In doing so, the strengthened layer and base material will be metallurgically combined in depth, which greatly enhances the wear and shock resistance of metal surface, 10 times that of laser cladding in efficiency. The machine tool is especially applicable for strengthening and repairing the central through and head & tail of all kinds of scraper conveyors. It is verified by many years uses in underground coal mines that the strengthened central through by cladding is prolonged 2-3 times in service life averagely.

Igjr-4/10 semi-conductor laser cladding equipment
Introduction
Laser cladding technology is interdisciplinary high and new technology refer to
Ray, mechanical, electrical, computer, material, physics, chemistry, etc. This technology is proposed in 60-70's of last century, and developed very fast with laser technology development from 80's of last century.Its working principle is melted alloy powder and substrate surfaces synchronously by the laser energy, and formed lowest dilutability layer of metallurgical bonding with matrix, can improved significantly matrix substrate surfaces performance of wear-resisting, corrosion resistance, oxidation resistance and so on, to achieve the aim of surface engineering or renovating.The laser cladding technology represents the highest level of strengthening the remanufacturing for the important precision workpiece, and also is the best technology that equip high performance alloy surface and no-effect the substrate properties on the normal base material.

Advantage of laser cladding:
1.In the future, will abolish chromium plating process because of environmental protection pressure.
2.Chrome plated workpiece can't satisfy the large mining height condition requirement contain corrosive gas or liquid.
3.The working life of laser cladding layer is 5 times than electroplate technology, at present, the hydraulic support of made-in china more than 7m and export require laser cladding.
4.The column next maintenance after laser cladding is very easy, only repair the local damage part, do not proceed this complicated technology of deplate-iron plating or welding repair-chrome plated again, saving time and money, better for the environment.
Application:
Almost whole inerratic axle for laser cladding equipment and rolling mill liner.
Powder feeder
With the development of metal material surface modification technology, powder feeder application become more and more wide for 3d printing , laser cladding, plasma cladding, thermal spraying, vapor deposition, and welding wire welding for cladding alloy powder for strengthening in the industry. To meet the above needs , overcome the deficiency in the existing powder feeder, we have succeeded in developing the third generation accurate powder feeder.
Feature
