Tungsten carbide nozzle, made of high grade tungsten carbide, is one of the spray nozzles. In another way saying, tungsten carbide nozzles are usually used to sandblasting, therefore, users also call them tungsten carbide sandblasting nozzles. The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining tungsten carbide spray nozzle, we do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place 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. tungsten carbide nozzle Tungsten carbide sandblasting nozzles are manufactured from hot pressing with straight bore and venturi bore type.

Tungsten carbide sandblasting nozzle also known as tungsten steel nozzles, type has a single inlet, double inlet and venturi nozzles. With high wear resistance, high hardness, high elastic modulus, high compressive strength, corrosion resistance, high impact resistance and other advantages. 30 times the wear life of steel, is three times the fine ceramic composite industry. As long as a negative high-pressure compressed air can rust, clean the surface of sa2.5-3.0 grade level. In hardware and machinery, casting rust polished glass mirror art of carving, sandblasting and other applications, are required preparation and sandblasting machine supporting tungsten carbide sandblasting nozzle. By their nozzles are in a variety of different designs of spray conditions, which use suitable nozzles needed to achieve optimum spray performance in use. Characteristics of the nozzle spray nozzle is mainly reflected in the type of shape that liquid from the nozzle opening formed and its operating performance. Named one spray nozzle is divided into a fan shape, tapered, solid stream (ie jet), air atomizing, flat nozzle, which is divided into a hollow cone nozzle cone and full cone two categories; while venturi nozzles (i.E. Mixing nozzle), strong cold (hot) and the outlet nozzle for hair tuyeres is reflected in the naming of the operating performance of the nozzle.
Tungsten carbide fan nozzle using heat treatment process, the overall high hardness, life expectancy is several times the stainless steel is widely used in washing cleaning, spraying, cooling, lubrication, dust control, fire protection, and other aspects of space and local humidification. Characterized by a tungsten carbide fan nozzle to produce high impact solid stream or fan spray jet angle of 0 ° -110 °. Spray nozzles such uniform distribution, the droplet size is small to medium. When the overlap requires a number of spray nozzles, spray tapering spray edge has a characteristic such that the coverage area of distribution. Spray angle refers to the angle of dispersed atomized liquid, even for the same nozzle, it also has a variety of spray angles can be selected for the specific needs of different customers, but even the same nozzle, at different pressures, the spray there will be a slight difference angle. Under normal circumstances, in the case of mounting height, constant pressure spray angle increases, its coverage is greater. Spray coverage is mainly affected by the height of the spray nozzle mounting angle and other factors, the other parameters are fixed at the nozzle, the nozzle spray angle, the more its wide coverage; mounting height of the nozzle is higher, the wider the spray coverage. Spray environment acid, alkali, high temperature, low temperature. The flow size of tungsten carbide fan nozzle spray is mainly affected by the pore size, pressure and the like. In general, the pore size of the nozzle holes, the greater the flow rate; under the same pore size, the greater the pressure, the flow rate will increase subsequently. In addition, the flow will be affected spray medium, the same aperture, under the same pressure and flow rate increases with reduced viscosity media.
Tungsten carbide oil nozzle mainly used in the oil and cooling water slurry erosion of the drill work. According to the drilling of the geographical environment of different designs using different water flow that water hole size and shape. Depending on the drill bit and interchangeability requirements for use with and without threads of two sub-threads, which non-threaded carbide nozzles are used in the cone bit, but carbide nozzles threaded application on pdc drill bit. According handling tools (wrench) have different cross-type points (four slots), y-shaped (3 slots), six square, within six square, plum-shaped and other five. Tungsten carbide nozzles are processed using precision machinery and carbide materials.

Tungsten carbide roll ring has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength, it is a key component of high-speed wire rod rolling. Tungsten carbide roll ring is mainly used for high-speed wire rod mill pre-finishing unit, and finishing units, reducing sizing unit, rolling play area and improve the performance of rolling material effect decreases. Tungsten carbide roll ring line production to meet the needs of making various types of high carbon steel, alloy steel and special steel. Tungsten carbide roll ring material is developed on the basis of the tungsten carbide tool material, it is made of refractory metal compound (WC) as a matrix, and transition metals (Co, Fe, Ni) as the binder phase. Tungsten carbide roll ring has good abrasion resistance, high-temperature red hardness, thermal conductivity and high temperature strength and other characteristics, it has been widely used in making high-speed wire rod, bar, rebar, and other rolling seamless steel pipe production. During normal use, the surface due to the impact of high frequency alternating thermal shock and hot water fog and thermal fatigue cracking, commonly known as crack, different forms of wear or fracture failure is the main reason in this case appears thermal fatigue crack initiation and propagation. When the groove face cracked it must be grinded to prevent crack propagation caused by abnormal breakage roller ring. Tungsten carbide roll rings performance requirements When the roller ring used, the roll diameter roller ring is smallest , and line the fastest, roll ring subjected to thermal shock highest frequency. Therefore, it requires roll ring material having excellent abrasion resistance to ensure the dimensions of finished wire after a certain amount of rolling ; and requires a high fracture toughness to resist the thermal expansion of the higher frequency shocks caused thermal fatigue cracks; the same time, need to have a high thermal conductivity to suppress thermal fatigue crack initiation. During use, the maximum operating speed of tungsten carbide roll rings up to 18000 r / min, and rolling up to the maximum temperature of the contact 1200 ¡æ. It is in this harsh working conditions, the roller ring wear resistance, toughness, resistance to thermal fatigue performance high demands. To achieve these performance requirements, often using coarse-grained low cobalt grades roller ring, such as WC-6% Co. Tungsten carbide roll ring characteristics 1. Contains a microscopic hard spots, have a high resistance to abrasion 2. The macro-hardness is high, up to 69 ~ 81HRC or more. 3. Material hardening tendency serious. 4. Material with low thermal conductivity. 5. High intensity of the material. 6. Stable chemical properties, very high melting point. Tungsten carbide roll ring using requirements Heap of steel rolling process is inevitable accident, the heap of steel rolling various causes overheating will cause the roller ring side, while at the other side of the water-cooled quenching effect, causing the roll surface heat cracks, restoring rolling when this heat leaving the roller ring rapid crack propagation easily cracked. Because rolling at high speed rolling finishing train, the temperature is high, when the stack of steel metal deposited on the roller ring groove around, due to the effect of high temperature molten metal ring attached to the roller surface, forming a "product turtle" phenomenon. In this case, local heating roller ring, resulting in heat stress, heat fatigue easily formed, if the roller ring continued use, the potential cause fracture failure. Remove the stack of steel roll ring, regardless of the groove is available, should be re-grinding, in order to eliminate the stress roll ring to prevent thermal fatigue crack initiation and propagation. Tungsten carbide roller ring has good heat conduction properties, down less hardness at high temperature, good thermal fatigue resistance, wear resistance, high strength, and other characteristics,so it is suitable for high speed rolling, and it become the good choice for roller ring.
