Atomized Ferrosilicon Powder as a welding coating auxiliary material

Atomized spherical heavy medium ferrosilicon powder is a common metal powder material with a wide range of applications. It is made of ferrosilicon alloy through atomization technology and has a spherical particle shape and a certain weight.

Atomized ferrosilicon powder uses high-speed airflow to spray molten ferrosilicon alloy into small droplets, and then cools and solidifies in the airflow to form spherical particles. By controlling the speed and temperature of the spray airflow, ferrosilicon powder of different particle sizes can be obtained. The specific process is as follows:

1. Mix silicon, iron and other elements in a certain proportion and load them into the atomization chamber.

2. Preheat the raw materials to reach the melting point.

3. Melt the raw materials into alloy liquid.

4. Use high-speed airflow to spray the molten alloy liquid into particles of equal size.

5. The particles are quickly cooled in the air to become powder.

6. The obtained ferrosilicon powder is screened to obtain the required purity and particle size.

This kind of ferrosilicon powder is a spherical particle formed by atomizing ferrosilicon powder with water atomization technology. Compared with ordinary ground ferrosilicon powder, the particle size is finer and more suitable for use in welding and other processes. Atomized ferrosilicon powder is often used as a welding coating auxiliary material, generally used as a deoxidizer in welding. You know, the welding process is not so easy, arc stabilizer. It is an easily ionized substance, mostly using potassium, sodium, and calcium compounds, such as potassium carbonate, feldspar, chalk, water glass, etc., which can improve the stability of arc combustion and make the arc easy to ignite.

Atomized ferrosilicon powder is a component of the coating, mainly used in the field of welding. Welding rods are a main material in the field of welding, mainly composed of welding core and coating. Welding rods without coatings not only cannot achieve good welding results, but also are difficult to operate during welding. Atomized ferrosilicon powder is generally made of ferrosilicon with a silicon content of about 45%/75%, processed by water atomization process. The addition of atomized ferrosilicon powder is more helpful to improve the deoxidation of welding rods and reduce the interference of oxygen in welding.

Atomized ferrosilicon powder is often used as a welding coating auxiliary material, generally used as a deoxidizer in welding. Welding usually refers to the welding of metals, which is a forming method that uses heating or pressurization, or both, to make two separated objects produce interatomic bonding forces and connect them into one. During the welding process, oxygen, nitrogen and water vapor in the air penetrate into the weld, which will have an adverse effect on the weld. Not only will pores be formed, but it will also reduce the mechanical properties of the weld and even cause cracks. After the electrode coating is melted, a large amount of gas is generated to cover the arc and the molten pool, which will reduce the interaction between the molten metal and the air.

As a manufacturer, Anyang Lishi Industrial Co., Ltd. has been selling well domestic and abroad for over 20 years. It is a production base of water-atomized ferrosilicon powder, a product exempted from inspection by domestic welding rod factories, and exported to Europe, America, the Middle East, Japan, South Korea, North Africa and other countries.
