The pinnacle of an amateur dart players' game is to score 180 with three darts. Whether you have already hit a maximum score, or are yet to achieve the feat, scoring 180 on a regular basis takes skill -- and hours of practice. Tungsten darts can be played in two forms - soft tip or steel tip. Regardless of which version you play, the approach and technique required to hit a 180 remains the same. Let’s learn how to get 180 in tungsten darts.

Hitting a Maximum

Align your dominant foot so that it is behind or level with the throwing line. Lean your body slightly forward towards the dartboard; this maintains balance and improves the chances of throwing accurately. Your eyes should be focused on the triple 20 target, not the dart.

Bring your throwing arm outwards, aiming the dart at a part of the treble 20 bed. Every dart player throws in his or chosen style, so it is best to throw in a way that you find comfortable and effective. Release the first tungsten dart; depending on your level of ability the dart should land inside the treble 20 section.

The first tungsten dart can be used as a platform to deflect the other tungsten darts into the same area of the treble, so it is advisable to aim at the barrel of the first dart. If the second dart lands near the first, you should be presented with a double platform, so aim the third dart towards the first two. This technique is known as stacking. When all three darts land in the triple 20, a 180 is scored.

Tungsten carbide fan-shaped nozzle uses heat treatment processing to enhance entire hardness and prolong lifespan, which is several times longer than stainless steel. It is widely used in cleaning, coating, cooling, lubricating, dust controlling, fireproofing and local humidification. The features of tungsten carbide fan-shaped nozzle is that it can generate high impact solid stream or fan spray jet angle of 0 ° -110 °, which has uniform distribution and the droplet size array small to medium. When the overlap requires a number of spray nozzles, spray tapering edge has a characteristic such that the coverage area of ​​distribution.

The flow size of tungsten carbide fan-shaped nozzle is mainly determined by the size of bore, pressure and so on. Generally, the longer diameter of the nozzle pores, the greater flow running out. The flow is in proportion to pressure, the larger pressure given, the faster flow will become. In addition, the flow will be influenced by spray medium, and the flow is inversely proportional to the viscosity of the medium in the same bore diameter under the equal pressure.

The structures of tungsten carbide nozzle invented are diverse so far. And various tungsten carbide nozzles have a great influence on its efficiency and lifespan. Therefore, a reasonable design will accelerate grinding process, improve efficiency and decrease the costs. The common structures like straight nozzle, conical nozzle, thread nozzle, venture nozzle, special nozzle, etc. Since nozzles appeared, its shape hasn’t change so much, and the straight bore nozzle has been used for a quite long time.

It is a kind of device that spraying water constantly and containing both of functions spray gun and nozzle. What’s more, it has a simple structure, which can be connected instead of seamless steel tube or drilling on materials. However, it always be used in some situation that has low demand in shooting peen because of short its lifespan. The conical tungsten carbide nozzle has a conical entrance for stream leading and a straight section for bundling, which is accessible for grind compound entering and makes them more uniform in section of nozzle than the straight nozzle. Other structures of special shape nozzles are quite complicate, which used in some special situations demands good bundling performance.

The most extensive material used for nozzles is iron, pottery, WC, SiC, B4C, etc. Tungsten carbide nozzle has good hardness, excellent anti-corrosion, heat-resisting, good toughness and a lot of performance, which can keep state under 500°C, even keep hard under 1000°C. Most of nozzles with other materials couldn’t make it. So tungsten carbide nozzle is widely used in chemical industry, food packaging, electronics, coating, machinery, constructions and so on. It is used for some surface treatment most of time, such as car cleaning, electrical equipments cleaning, iron parts surface coating, and turbine cooling, etc. Especially when handling and cutting grind compounds (glass drops, steel shots, and cinders) is unavoidable, and tungsten carbide nozzle will show its economical and long lifespan. In addition, tungsten carbide nozzle can also used in string pulling and guiding.

Tungsten carbide nozzles are divided by its different shape of nozzle’s bore, while the shape will determine its blast pattern. A normal tungsten carbide nozzle always has one straight bore, limit bore or venture bore. Straight bore is the most common, which creates a sealed blast pattern for spot blasting or blast working inside. It is suitable for smaller jobs such as parts cleaning, welding fabrication, cleaning handrails, steps, grillwork, or carving stone and other materials.

Venturi bore nozzles forms a full blast pattern and accelerate grinding as much as 100% under a given pressure so that it is the best choice for larger surface to enhance the efficiency. Long venturi nozzle raises 40% velocity in productivity and saves 40% grinding compounds compared with straight bore nozzle. Wide throat nozzle is also called wide angle nozzle, which is divided into big and small droplet specifically. It is designed that a large entry and diverging entry bore. When matched with the same sized hose, they can increase 15% in productivity compared with nozzles with a smaller throat. In addition, there are some diverse angle nozzles for specific spots like bridge lattice, behind flanges, or inside pipes.

Tungsten carbide nozzle is made from hard materials (superhard alloy) by precision machinery, and its anti-bending strength can reach over 2300N/mm, hardness can reach over 90HRA. It is necessary that do the precise grinding and surface treatment when machining tungsten carbide nozzle, and make sure to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. In addition, there is a scientific curvature radius design between the two entrances. This design ensures a smooth transit of the thread. Due to the overall materials processing, no elevation in the drilling bore, it is beneficial for improving the phenomenon of bending and blocking.

Tungsten carbide nozzle is sintered from straight bore and venturi bore type. Owing to its good hardness, low density and excellent wear-resisting, Tungsten carbide nozzle has been widely used in sandblasting and shooting peen equipments so that it can offer a long lifespan in optimum air and grinding materials.
