The addition form of ferro chrome nitride in smelting

Ferro chrome nitride is added to the molten steel in bulk or ball form. The specific methods of joining are as follows:

1, melting: the chromium nitride is heated to the melting point, so that it becomes a liquid, usually using an electric furnace or alumina furnace for melting.

2, pouring: the molten chromium nitride uniformly poured onto the surface of the liquid steel, through natural immersion or mechanical mixing, so that the chromium nitride evenly distributed in the liquid steel.

3, stirring: After adding ferro chrome nitride, it is necessary to stir the liquid steel, so that the ferro chrome nitride is quickly and evenly dispersed in the liquid steel, which helps to improve the nitriding effect of the entire liquid steel.

Chemical composition of ferro chrome nitride

Ferro chrome nitride is a kind of high hardness metal material, its chemical composition mainly includes iron, chromium and nitrogen, in the specific chemical composition, ferro chrome nitride contains different proportions of iron and chromium, while there is a certain amount of nitrogen.

Iron is one of the main components of ferro chrome nitride, and its content is usually more than 50%. Iron is an important metallic element that is commonly found in rocks and minerals on Earth. In ferro chrome nitride, the main role of iron is to provide the structural and mechanical properties of the material, such as hardness, toughness and strength. At the same time, iron can also improve the wear resistance and corrosion resistance of ferro chrome nitride.

Chromium is also one of the important components of ferric chromium nitride, and its content is usually between 20% and 40%. Chromium is an important alloying element, which can significantly improve the corrosion resistance and heat resistance of metal materials. The main function of ferro chrome nitride is to improve the corrosion resistance and high temperature resistance of the material. In addition, chromium can also improve the hardness and mechanical strength of ferro chrome nitride.

Nitrogen is also one of the important components of ferric chromium nitride, and its content is between 5% and 15%. Nitrogen is a common nonmetallic element with high chemical activity. The role of ferro chrome nitride is to improve the hardness and wear resistance of the material. The compounds formed by nitrogen with iron and chromium have very high hardness and strength, which can significantly improve the mechanical properties of ferro chrome nitride.

The chemical composition of ferro chrome nitride mainly includes iron, chromium and nitrogen, which has good hardness, toughness, wear resistance and corrosion resistance. In practical applications, ferro chrome nitride is widely used in machining, cutting, stamping and forming fields, is one of the important engineering materials.

 

Preparation and production method of ferro chrome nitride

Ferro chrome nitride has high hardness and wear resistance, but also has good corrosion resistance and high temperature stability. These excellent properties make ferro chrome nitride used as a material for corrosion resistant equipment in the field of mechanical manufacturing and chemical industry.

There are two main methods for the preparation of ferro chrome nitride

One is prepared by gas phase reaction, and the other is prepared by solid phase reaction. The gas phase reaction method is to mix chromium and iron powder and react with nitrogen at high temperature to produce chromium ferric nitride. The solid phase reaction is to mix chromium and iron powder and react with ammonia at high temperatures to produce ferro chrome nitride.

 

In addition to the above preparation methods, ferro chrome nitride can also be prepared by arc melting. This method is to mix the powder of chromium and iron, melt it through the method of arc melting, and then quench it in an ammonia atmosphere, and finally get ferro chrome nitride.
