What are Tungsten Cylinder Counterweights?

Tungsten Cylinder Counterweights sometimes referred to simply as crankshafts, are the main rotating parts of the engine, which can undertake the up-and-down (reciprocating) movement of the connecting rods into cyclic (rotating) movements, and are one of the most important parts of the engine. Tungsten Cylinder Counterweights have two important parts: the main journal and the connecting rod journal: the main journal is installed on the cylinder block, the connecting rod journal is connected with the big end hole of the connecting rod, and the small end of the connecting rod is connected with the cylinder piston, which is a typical crank Slider mechanism. The lubrication of the crankshaft mainly refers to the lubrication of the bearing bush of the rocker arm and the lubrication of the fixed points at both ends. The power source of the engine when the crankshaft rotates. It is also the source of power for the entire mechanical system.

How do Tungsten Cylinder Counterweights work?

The Tungsten Cylinder Counterweights can connect the piston and the crankshaft with a connecting rod. When the piston moves up and down, the connecting rod makes a circular motion, and then the Tungsten Cylinder Counterweights start to rotate, driving the flywheel on the crankshaft to transmit the force.

What are the advantages of Tungsten Cylinder Counterweights?

The engines of Tungsten Cylinder Counterweights use counterweights to keep each piston reciprocating and connecting rods balanced. These counterweights are Tungsten Cylinder Counterweights. Lead is inexpensive, but has a lower density than Tungsten Cylinders. It is toxic, and causes environmental pollution. For steel, the Tungsten Counterweight is twice as dense. Therefore, Tungsten Counterweight is more suitable for crankshafts than other materials. Tungsten Cylinder Counterweights have the following advantages: high density, small size, high hardness, high wear resistance, good corrosion resistance, impact resistance, high melting point, high-temperature resistance, and non-toxic and non-polluting.

Since Tungsten Cylinder Counterweights have the advantages mentioned above, Tungsten Cylinder Counterweights can be used in engines on aircraft, ships, and spaceships. Today, tungsten alloy crankshafts are widely used in high-performance racing engines.

Advantages Of Tungsten Carbide Strips

Tunsgten cemented carbide strips is mainly made of WC （tungsten carbide） and Co （cobalt ）mixed by metallurgical method through powder making, ball milling, pressing and sintering, the main alloy composition is WC and Co, the composition content of WC and Co in cemented carbide strips for different applications is not the same, the use range is extremely wide.

Cemented carbide strips are named after the rectangular shape of the slab (or square), also known as carbide long plate.

Advantages of tungsten carbide strips is as below:

1. High purity raw material with little impurity content and more stable physical properties.

2. Using spray drying technology, the material is protected by high purity nitrogen gas under fully sealed conditions, which effectively reduces the possibility of oxygenation during the preparation of the mixture, with better purity and less dirtying of the material.

3. Uniform density: 300Mpa isostatic press is used for pressing, effectively eliminating the generation of pressing defects, and the density of the blank is more uniform.

4. Excellent denseness, excellent strength and hardness indexes: the adoption of ship low-pressure sintering technology effectively eliminates the pores inside the long bar, and the quality is more stable.

5. Using deep cooling treatment technology, the internal metallographic organization of the long bar can be improved, and the internal stress can be greatly eliminated to avoid cracks during the cutting and forming process of the product.

 Classification of carbide roll

Tungsten carbide rolls are one of the materials in great demand in steel mills, and it is mainly divided into four categories: high-speed wire rolls, new generation of high-speed wire hot rolling rolls, new generation of high-speed wire review rolls, and cold-rolled three-dimensional rolls.

 The carbide rolls produced by Zhuzhou Jinxin Cemented Carbide Company have better thermal conductivity, higher wear resistance and corrosion resistance, and good general performance, which obviously reduces the depth and width of thermal cracks in the rolling groove during rolling and reduces the risk of roll shattering.

The new generation of high-speed wire hot rolling rolls has higher impact resistance, thermal fatigue resistance and high wear resistance compared with high-speed wire hot rolling rolls, and is suitable for high-speed wire rolling at speeds over 100 m/s.

 The new generation of high-speed wire rod composite rolls can significantly reduce the number of slot and roll changes, reduce labor intensity, improve labor productivity, improve the surface quality of the rolled material and the percentage of finished material in the front frame of rebar and bar mills, thus obtaining significant economic benefits.

 Cold-rolled ribbed steel bars rolled with cold-rolled three-dimensional rolls have beautiful surface appearance, high dimensional accuracy, clear rib marks, and change the performance of ribbed steel bars to improve their strength. The volume of one rolling is (800-1500 tons), which is (20-50) times higher than that of ordinary tool steel material. It can be repeatedly resharpened and used, which greatly reduces the cost and significantly improves the effectiveness and efficiency.

Why More And More People Choose Tungsten Fishing Sinker?

The fishing sinker is used to increase the diving power, anchoring power, and throwing speed of the bait. The fishing sinker can be as small as 1/32oz for shallow water, and even smaller for flying fish. Or up to ten ounces for deep sea fishing. They can come in a variety of shapes, and environmental concerns are a major concern when choosing fishing sinker materials.

A fishing sinker is usually made of lead with a hook and is usually covered with a soft material to attract fish. In recent years, however, tungsten alloys have become increasingly used as fishing sinkers.

The high specific gravity tungsten alloy with clean metal as raw material has heavy density(>18g/cc), small volume, strong wind resistance, light water entry and fast sinking, so it is a good substitute product for lead sinker.

Changsha Jingxin provides fishing sinkers, tungsten ball, tungsten weight, various shapes such as: drop shape, bullet shape, fish mouth shape, ball shape, etc. Tungsten alloy is also used in other products for fishing, such as carbide cutters for cutting high power fishing lines.

Why we should choose tungsten alloy counterweight for the crane?

What is a crane?  Does the crane still need counterweight?  Why choose tungsten alloy counterweight block?  See this title, you must have doubts, here we will see the answer one by one.  

Crane is also derrick, mainly consists of power device and support two parts, in the lifting time, the counterweight is very important, the counterweight is mainly to maintain the balance of the block.  Its weight is generally added according to the strength of the car itself, too heavy, too light have disadvantages.  If it is too heavy, it is likely to cause damage to the strength of the car when lifting the weight;  If it is too light, it is likely to roll over.  In order to make the car more versatile, some large tonnage crane balance block is removable, when lifting small tonnage materials, the car can be hung less or no balance block.  However, when hoisting large tonnage items, the balance block must be fully hung, and even the excess device must be added to prevent the occurrence of overturned, resulting in casualties and damage to goods.  

When you look at this, you may think that other material counterweights can also be available, as long as the weight is up to the standard.  Why choose expensive tungsten alloy counterweights?  That is because of the high density of tungsten alloy, corrosion resistance and oxidation resistance.  The high specific gravity tungsten alloy as the key raw material, tungsten alloy density, so as to achieve the purpose of small volume and large weight, high flexibility, long service life.
