Many people who want to sell their tungsten carbide power always distress where to sell and how to sell them in a good price. They had better expand their information and create credibility to get more and more visit. This is not only save times and energy, but also improve the efficiency of tungsten carbide powder recovery. This recycle method is called waiting for customers.

In simple words, tungsten carbide powder recycling is nothing more than recycling enterprises of the unwanted tungsten carbide powder material. Sometimes we go to some enterprises, there are some waste tungsten carbide power left. At this time, in order to treat these waste material with an easy method, they will like to give us a low price to recycle them. So going to related enterprises is a practical method for recycling tungsten carbide powder.

Nowadays more and more people like to solicit business by calls. In fact, some people who does the business of recycling tungsten carbide power use calls to get business. But it is often difficult to get an effectively  call. In spite of this, people still not give up using this method to get their business.

Waste Tungsten Carbide Roll Ring Process

The processing principle of waste tungsten carbide roll ring is that making the inside filling up through a core shaft. And finally reach the clamping effect. Generally speaking, it can make thin wall sleeve expansion of 0.15mm.

Wast tungsten carbide roll ring should choose cutting fluid reasonably, that can promote friction in grinding process, decrease grinding heat. the most important function of cutting fluid is cooling, lubrication, cleaning, rust. The selection of grinding fluid has a big influence on grinding hard alloy scrap tungsten carbide roll ring. Good grinding fluid can promote work efficient and decrease roughness value of work piece surface.

The wheel sand of wast tungsten carbide roll ring is made of abrasive and binder. It is processed through several steps, such as limit, boring and sintering. It is also composed by abrasives, binders and space. Abrasive is equivalent to the cutting blade which owns cutting action. Space is favor of removing chip and heat dissipation. In general, people like to choose diamond grinding wheel which regard resin and bronze as binder. This will play a good role in batch processing of waste tungsten carbide roll ring.

Reduction Size Of Tungsten Carbide Powder Oxides

There are many factors that influence reduction size of tungsten carbide powder oxides. Such as tungsten carbide powder properties, impurities, and temperature. Restoration activity of tungsten oxide has obvious effect on the particle size of tungsten powder. Material with bigger restoration activity is more easier to get the tungsten powder with fine grained.

The influence of impurity elements in tungsten particles change, can be divided into three categories. The fist category is that impurity elements which represent by alkali metal can play the carrier effect of oxygen. It can promote chemical reaction and enhanced tungsten powder particles grow. The second one is that calcium, magnesium and silicon have little influence on tungsten particles growing. Besides materials which represent by aluminum can form a thin oxide layer with high stability. Elevated temperature can accelerate the reduction reactions. And it also speed up the creation of water vapor, particle growth and aggregation.

Partial pressure of water vapor is a main factor to powder particle size and shape change. Water vapor is a basic condition to chemical vapor removal reaction, it includes water vapor in hydrogen and reduction reactions. It is not a stable value in the process of recovery.

Technology Of Manufacturing Dies By Tungsten Carbide Powder

Tungsten carbide powder is in high demand for many industries which is used for manufacture stamping dies. In order to meet the requirements of quality and demand, technology of tungsten carbide power manufacture the dies and its material have been improved constantly.

Tungsten carbide powder is main material for making hard alloy. It has metallic luster and its hardness is similar to diamond. As we all known, tungsten carbide power is good conductor for electricity and heat. The sliding fit part and frequent strike of cemented carbide stamping die have been worn for long time in working process, it has an obvious influence on the mould quality.

The raw material of tungsten carbide powder has high hardness, strength, wear resistance and corrosion resistance. It is a very important factor to improve the mold quality. So that it easily to meet the quality requiment. People should also ensure the mold own enough strength while designing. Corner for each surface is designed into the fillet after filtering which can avoid the stress concentration. It can protect manufactured parts, concave die, cavity and part convex die. It has improved technological content of manufacturing products and high quality stability.

Chemical Reaction Value Of Tungsten Carbide Powder

Carbide tungsten powder plating bluish white, it is an alloy coating with good corrosion resistant. Carbide tungsten power is used for watch and bicycle part. They always own good weldable and very suitable for electronic components and printed circuit board. Adding cobalt and nickel electroplating gloss can make them plump. At the same time, it will improve the hardness of pure nickel layer, the lower contact resistance. So it can not only be regarded as protection and decoration coating, but also as mechanical plating, electroplate.

People have been studying alternatives and iron powder as the cemented carbide. Because the carbide tungsten power usually expensive and the resources are scarce. Now carbide tungsten power don’t need any payment technology. Due to radioactive of carbide tungsten power, the large amount of development work only made by more stronger enterprise. While whole development process is in large requires. Generally speaking, the tungsten carbide powder with radioactivity is harmful to human body. However as a strategic resource of a country, only master the development of tungsten carbide powder with high level cold keep it in the leading position in the world.

Adding special material to the metal carbide tungsten has important position in metal product industry. At present, tungsten carbide powder is essential in many nonferrous metals enterprises.

Metallurgy Of Tungsten Carbide Powder

In recent years, metallurgy technology of tungsten carbide powder developed rapidly. Sintered casting, temperature and pressure skills, injection molding, sinter hardening are used more and more widely. At present, powder casting is a primary forming skills in tungsten carbide powder metallurgy mechanical parts industry. Its shape has been changed by hot forging or cold forging. It has completed high density.

Chinese car and motorcycle market have very great potential. On one side, the motorcycle is still occupy the first market. But with a series of resolution and plan have been carried out, motorcycle market will be further expanded in the China West. On the other hand, the current national car market carried out another round of market competition.The revival and development of this occupation offered key point to tungsten carbide powder metallurgy.

From the international development trend, carbonized tungsten powder metallurgy gear can reduce the advantages of parts components and attracted more and more attention to the field due to its cheap price. For example, the number of each tungsten carbide powder metallurgy part in car has been increased quickly in the area of north America and Europe since 1990.
