Cemented Carbide Nozzles
A cemented carbide nozzle is a device designed to control the direction or characteristics of a flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe via an orifice. For nozzles, there are a lot of materials which can be used to make nozzles. Of all kinds of nozzles, cemented carbide nozzles are the most rugged and durable nozzles.

Cemented carbide nozzles are made from the precision machining with the cemented carbide materials. The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining cemented carbide nozzle, we do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the Replace of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging has been improved comparing with the ruby nozzle.

Cemented carbide nozzles are made from hot pressing with straight bore and venturi bore type. Due to its hardness, low density and excellent wear and anti-corrosion, they have been widely used in sandblasting and shot peening equipment, offering a long life with optimum air and abrasive use.

Cemented carbide nozzle and other nozzles

Common nozzle materials include cast iron, ceramic, tungsten carbide, silicone carbide, and boron carbide. Cast iron nozzles are now very rare as they wear out after just 6 to 8 hours. Ceramic nozzles are used only with non aggressive abrasive in light duty equipment and blast cabinets. Tungsten, Silicon, and Boron Carbide are the most popular for the majority of blasting applications due to their long life. Comparisons among cementd carbide nozzle and other nozzles service life are listed below.

Applications of cemented carbide nozzles

Cemented carbide nozzles are widely used in such industries as surface treating, sandblasting and painting, electronics, chemical processes.

Cemented carbide nozzles are also used in different applications like for wire straightening, wire guides and others.
