Chromium carbide is a commonly used cemented carbide material. Our company is a professional manufacturer of tungsten carbide coating. Then, let's learn how chromium carbide is manufactured!

Chromium carbide combines metallic chromium and carbon to form tungsten carbide. In fact, you 'd be surprised how many uses this durable metal has. Chromium carbide has a lot of significance in military and industrial applications, but there are also many household products, including chromium carbide. This is because it is an alloy metal material with excellent performance.

In the manufacture of chromium carbide, compounds of chromium and carbon are combined at temperature. The temperature required to heat the crushed chromium, the temperature of the carbon, is about 1,400 to 2,000. 1920 appeared in Germany commonly used chromium carbide manufacturing method. This method is carried out by taking out powdered chromium carbide and mixing it with cobalt. The heat is enough to slightly dissolve the chromium carbide, and the chromium carbide becomes a cement-type material. Chromium carbide has a special name. This chromium carbide is made of hard metal or Carboloy.

Although this is not the method of manufacturing chromium carbide. Another common method is to use a pulverizer to convert both chromium and carbon into powder. These powders were then collected and transferred to a crucible. Here, the two materials are welded with electric heating powder to generate chromium carbide.

The manufacture of chromium carbide starts from the ground

Of course, the above method briefly summarizes the preparation process of chromium carbide, but there are many more in the whole process. Let's start with the manufacture of chromium carbide. It's underground mining.

It can be seen that a variety of tungsten ores can be obtained from the ground, refined into so-called chromium, ready to be converted into so-called chromium carbide. Among the available chromium ores, wolframite is widely known. Chromium ore is crushed, then heated and mixed with a range of chemicals. When the new material cools, chromium oxide is produced.

Then carburizing is tungsten oxide, a process that adds carbon to chromium oxide at high temperatures to form a process called tungsten carbide. One method is to mix chromium carbide and graphite. Then by heating the combination to a great height, a chemical reaction takes place that manages to absorb the oxygen found in the oxide. In this way, carbon can be fused with tungsten to form tungsten carbide.

Grain size is important for chromium carbide

One of the main factors affecting the formation of chromium carbide is the size of the grains. Carbides can affect the mechanical properties of the compound. Moreover, the size of the crystal grains is affected by the size of the chromium oxide particles in addition to how long the heating process lasts and at what temperature the heating process is.

It should be noted that your standard chromium carbide particles are very small, much smaller than sand grains. The large particle size is about 10 microns and the small particle size is about half a micron. These particles pass through a sieve that separates the sieve or different particles into aggregates of similar size. This is the step of generating tungsten powder. Considering the importance of chromium carbide and a wide range of applications, the manufacturing steps of chromium carbide are far more complicated than the above, and the later chromium carbide spraying is also small for tungsten carbide applications.
