People who dabble in darts don't realize that cricket is a strategy game. Learn the rules, then develop your technique. The instructions of how to play American Cricket tungsten darts is:

1.Play with two people or four people on two teams.

2.Write the numbers 20 down to 15 vertically on each side of the scoreboard. Put a letter "B" (for "bull's-eye") below the 15, and below that write "points."

3.Throw three darts at a time, alternating players. Remove the darts after your turn.

4.Count any darts that land in the bull's-eye or numbers 15 through 20. Don't award points for hits on the numbers 1 through 14.

5.Mark a slash on the scoreboard next to a number when you hit one. The second time you hit, make a second slash to form an X. The third time, circle the X.

6.Count the number twice if a dart lands in the doubles ring (the narrow one around the outside), and count the number three times if a dart lands in the triples ring (the smaller one between the doubles ring and the bull's-eye).

7.Close out a number by hitting it three times. Once an X is circled, that number is closed.

8.Hit a number that you've already closed but your opponent still has open, and you get points: If you closed 15 and then hit it again, you get 15 points, which you write in the points area. If you closed the bull's-eye and then hit it again, you score 50 points.

9.Total up all of the points when one player closes out all of his numbers plus the B. The person or team with the most points wins.

10.Keep playing if you close all of your numbers before your opponent but are behind in total points. You can win only if you accumulate more points than your opponent before he closes out all of his numbers.

Tips & Warnings

Try to close numbers that your opponent has closed to keep him from scoring more points.

Points don't start accumulating until the number is closed.

A variation called "no slop" requires the players to close out the numbers in order starting with 20 at the top and working down to B at the bottom.

Tungsten dart sharpeners are very important in the game of darts. Without sharpening the tips of darts, they get dull and don't stick in the board. When darts don't stick in the board, the thrower gets no points awarded. No matter how perfect a player's aim is, in the end it won't matter if their tungsten darts don't stay in the board. Here's how to use a dart sharpener to make sure that the darts stay stuck in the dart board.

Rub the end of the dart on the stone. Hold the tungsten dart parallel to the sharpening stone and lightly rub the dart’s end across the stone’s surface. Make sure to rotate the dart to properly sharpen all sides. Check the tip continuously to ensure that it is sharpening properly and adjust sharpening accordingly.

Check the shape of the dart tip. Perfectly sharpened tungsten dart tips are not pointed; they have a slightly rounded tip. The tip needs to resemble a ball point pen tip to properly stick in the dart board. If the tip gets a point on it, lightly rub the end on the sharpening stone in circles until it is rounded.

Don't overdo it. Tungsten darts sharpened to a point are too sharp. These tungsten darts often don't stick to the dartboard, instead bouncing off and falling to the floor. They also run the risk of damaging the wiring on the board due to their sharpness. New darts in packaging come too sharp to play with. Round the tips of the darts down with the dart sharpener before using them so that they’re not too sharp.

Use it frequently. Check the tips of darts before throwing them. It’s probably not necessary to sharpen the tips between every throw, but it does occasionally happen that the tip needs a touch-up. Definitely sharpen darts between games to keep them in top shape.

Watch for signs of a bad tip. A bad tip is a tip that is too sharp or completely unsharpened. When playing, the biggest sign of a tip that needs sharpening is the dart bouncing off the board. Sharp, pointed tips slide in without sticking, and bounce off the backing, and flat darts make a big hole that they slip right back out of. This happens both when the tip is too sharp, and when it's not sharpened, or flat.

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.
