Tungsten alloy gamma ray shielding material overcomes the shortcomings of traditional lead shielding material, and is more often used in medical fields. More specifically, tungsten alloy gamma ray shielding material does not produce secondary bremsstrahlung, and has a high hardness, which can maintain a certain shape very well when it is made into large containers and large equipment. But if lead is used as the gamma ray shielding material for manufacturing large containers and large equipment, in order to avoid the collapse of the containers and equipment due to their own weight, it is necessary to use steel as the structural framework.

How to choose sawtooth angle of tungsten carbide saw blade? The angle parameters of sawtooth of saw blade are more complicated. It is the key of cutting quality of workpiece by correctly selecting the angle parameter of saw blade.

How to choose tooth form of tungsten carbide saw blade? There are many kinds of tooth forms for tungsten carbide saw blades, including flat teeth, trapezoid flat teeth, left and right teeth, dovetail teeth, inverted trapezoidal teeth, and so on. Well, how to choose tooth form of tungsten carbide saw blade?

How to choose tooth number of tungsten carbide saw blade? Normally, the more tooth number of tungsten carbide saw blade, the better the cutting performance. However, the large number of cutting teeth means that the price of the saw blade is higher.

Tungsten carbide saw web is the most commonly used cutting tool for processing wood products, and is often used for sawing and grooving metal materials. The quality of such a saw web is closely related to the quality of the workpiece to be processed. In other words, choosing a suitable tungsten carbide material to manufacture tungsten carbide saw blades is important for improving the quality of workpieces, shortening processing cycles, and reducing processing costs.

Tungsten carbide fan-shaped blade has the characteristics of high hardness, high compressive strength, high temperature resistance, good wear resistance, good chemical stability (acid resistance, alkali resistance, high temperature oxidation resistance), low impact toughness, small thermal expansion coefficient, and long working life.

Tungsten carbide slitting circular blade has a long working cycle as it has characteristics of high hardness, high strength, sharp cutting edge, good wear resistance, acid resistance, alkali resistance, corrosion resistance, oxidation resistance, rust resistance and high temperature resistance. The service life of such a tungsten carbide blade is more than 10 times the life of high speed steel blade. And the service life of tungsten carbide slitting circular blade after coating is dozens or even hundreds of times that of high speed steel slitting circular blade.

The researchers proposed a new process for recovering ammonium tungstate from APT crystallization mother liquor. This process improved the existing problems of high consumption of auxiliary materials, high production cost and large energy consumption in the prior art.

The researchers proposed a preparation method of ammonium paratungstate (APT) using tungsten-contained soft waste material. And the obtained APT can be directly used in the production of tungsten alloys or be applied as additives for chemical products.

Researchers have proposed a method for producing ammonium paratungstate using tungsten-contained waste material, which has the advantages of short production process. Evaporated and crystallized waste ammonia gas and wastewater can be recycled and reused. And it significantly reduces emissions of waste gas and wastewater. Also, it improves the tungsten recovery rate.
