Tungsten carbide assemblies are designed with carbide and other metals in order to supply parts meeting the application needs while controlling the production cost. These parts are produced for wear solutions for various industries,including wire working plants,oil and gas,chemistry,construction machinery,etc.
Today we are introducing some main techniques to produce carbide-steel assemblies by Oston Carbide.
1.Shrink fit
Shrink fit is usually used for assemblies with outer metal bushing and inner tungsten carbide bushings,an interference fit is adopted in order to prevent the fit from loosening during application,the heated steel outer sleeve is pressed into the cemented carbide inner sleeve. The interference amount of the hole must be reasonable to prevent the steel outer sleeve from being too large,and Insulation is also required to remove internal stress.
2.Brazing
The inlaid carbide jacket is mostly welded by molten copper, and generally adopts a gap fit, so that the molten copper flows smoothly into the gap. If an interference fit is used, use a small interference fit to prevent cracking. In order to remove internal stress, keep warm in time after brazing, put it in an oven or embed materials with better heat preservation, and slowly drop to room temperature.
Oston Carbide can provide different brazing materials. Brazing methods include high-frequency induction brazing, flame brazing, resistance brazing, and vacuum brazing which can be applied to products,we continue to provide our customers with high-quality precision parts and assemblies.
3.Mechanical connection and glue.
It is fixed by physical cold extrusion, with small interference of steel material and hard alloy sleeve and fixed by fine thread extrusion, and the thread connection is coated with locking anaerobic adhesive.adhesive connections are adopted for some products which greatly reduces production risks and costs.
Oston Carbide is always committed to providing assemblies for harsh working conditions,which can be used to optimize designs for different wear solutions.
