How important is the production of ferrotungsten powder?

Release time:2021.12.18Publisher:ferrotungsten powder

Ferro tungsten is a very important material in industry, and its application is very wide. It can be seen in various industrial fields such as mining, metallurgy, machinery, construction, transportation, electronics, aerospace and military industry.

The production and production of ferro-tungsten powder, in the traditional production method, mainly uses wolframite concentrate as raw material, mixed with additives according to a certain ratio, and then smelted in an electric furnace. However, this method is no longer applicable nowadays. In today's production of ferro-tungsten powder, new developments have been ushered in with the important advancement of science and technology.

1. Preparation: First, the tungsten-containing waste is purified by metal to separate the valuable metals in the waste, and at the same time, the tungsten content is increased and controlled at 60-70%.

2. Put the purified materials into a roasting furnace for drying and roasting, controlling the temperature at 500°C, roasting for 8 hours, and then cooling to room temperature.

3. Calculate the required batching quantity based on the tungsten content in the material, and prepare the material according to the following weight ratio: Tungsten-containing waste after treatment: 60~70% ferrosilicon: 15~19% aluminum powder: 14~17% nitric acid Sodium: 2 to 5%, calcium fluoride: 1 to 2.5%.

4. Put the above materials into the mixer and mix for 30 minutes to make the materials fully mixed.

5. Put the mixed materials into the prepared reaction furnace several times, first make the volume of the mixed materials account for one-third of the volume in the reaction furnace, ignite, and control the furnace temperature at 3400~3600℃. During the process, gradually add the mixed materials. When the volume of the molten pool in the reactor reaches three-quarters of the volume in the reactor, open the discharge port at the bottom of the reactor to slowly release the solution and let it flow naturally to the nitrogen On the plate of the plate centrifuge under protection, the solution is thrown into the collection chamber around the centrifuge plate through the action of the high-speed rotating centrifuge plate.

6. When the temperature is cooled to room temperature, collect the materials in the collection chamber, and use the wind sorting and screening equipment to obtain spherical tungsten iron powder with uniform particle size.

What Kind of Tungsten Carbide Powder is a Good Product?

Tungsten carbide powder has a very important application in many industrial production and processing. It has high purity, uniform particles and good dispersion. It is an important raw material for the production of cemented carbide.

Why is Tungsten Mud Fishing Tackle So Popular in the Market?

Tungsten mud fishing tackle is a popular product in the fishing tackle market. Many fishing enthusiasts usually choose this new type of tungsten mud fishing tackle when choosing fishing sinks.

The Research and Development Technology of Alloy Powder has been Continuously Upgraded

Alloy powder refers to a metal powder formed by partial or complete alloying of two or more components. There are many different branches in alloy powder, such as ferroalloy powder, tungsten alloy powder and other important metal alloy powder, and these different types of alloy powder also play an important role in many industries.

Customized Tungsten Powder, the "Tough Guy" in the Rare Metal Industry!

In the rare metal world, many members have very tenacious labels. They not only have high melting points, but also have very strong corrosion resistance, and are not easily oxidized in the air, so they are also called rare metals. The "tough guy" of the world!

Talking About the Current Situation of Recycling and Utilization of Coarse Tungsten Particles in the Tungsten Industry

The development of the tungsten industry is now showing a trend of continuous expansion. Metal tungsten consumes more and more energy. Therefore, the recycling of coarse tungsten particles in the tungsten industry has also attracted the attention of many countries.

When Buying Tungsten Powder, the Brand is Very Important!

The purchase of tungsten powder is a very important work for many industrial manufacturers. As we all know, the use of tungsten powder plays a very important role in many industrial production, especially in the metal processing industry, where the use of tungsten powder is indispensable.

Color-changing Tungsten Trioxide Escorts the Production of Smart Glass!

In the current society, the R&D and production of smart glass are becoming more and more common. This important measure, which can provide a good indoor space and reduce the energy consumption of buildings, is naturally welcomed by many parties.

Learn the Specific Information and Data of Tungstic Anhydride

Tungstic anhydride, the name is somewhat unfamiliar to many people, but if you want to talk about tungsten trioxide, then people will suddenly understand, it turns out that it is an oxygen compound synthesized by tungsten and oxygen elements.

What are the Differences Between Yellow Tungsten and Blue Tungsten?

Yellow tungsten and blue tungsten are both very typical transition metal-oxygen compounds. They are both products composed of tungsten and oxygen elements.
