Product Description

Calcium Iron Alloy Cored Wire13mm With Customized Production For Steelmaking

 

Calcium iron cored wire is also called calcium iron alloy cored wire, which is an alloy cored wire made by mixing metal calcium with a certain proportion of iron powder and covering it with a steel strip. The calcium-iron cored wire consists of a mixture of 28%-35% calcium particles and 65%-72% iron powder as the core material, and the inner core is wrapped with a cold-rolled low-carbon steel strip as the sheath. As major iron and steel companies have strict requirements on the form and quantity of low carbon steel, ultra-low carbon steel, low silicon steel, and their inclusions, calcium iron cored wire is generally selected for calcium treatment of pure steel.

Why Use Calcium Iron Cored Wire?

The invention of the alloy cored wire is to solve the problem that the alloy deoxidizer such as the calcium iron cannot reach the deeper position of the molten steel to react. Although calcium is a strong deoxidizer, because of its relatively light specific gravity and low melting point, it is easy to generate bubbles at high temperatures. Therefore, simply throwing calcium metal particles or calcium powder into the refining furnace will quickly cause combustion and cannot enter the upper or deeper position of the molten steel, thus failing to achieve the desired purification effect. On the other hand, the gasification of calcium particles in the molten steel will form a larger vapor pressure, which will cause the molten steel to splash violently, which directly affects the service life of the electrode and the smelting furnace.

Use a mixture of 28%-35% calcium particles and 65%-72% iron powder as the core layer of the calcium iron cored wire, and the outer layer is wrapped with a cold-rolled low-carbon steel strip to make the calcium-iron cored wire. This kind of an operation mainly uses iron to increase the specific gravity and melting temperature of calcium particles, so as to alleviate the rate of calcium evaporation and reduce costs at the same time. In addition, the iron powder itself has a certain weight, which can speed up the sinking speed of the calcium iron cored wire, so as to quickly reach the ideal position.

Advantages Of Calcium Iron Cored Wire

  • As a commonly used deoxidizer in the refining process of molten steel, adding calcium iron alloy cored wire in the steelmaking process can avoid the formation of long strips of sulfide inclusions, thereby improving the anisotropy of steel.
  • The calcium-iron cored wire is quickly fed into the molten steel with the help of a wire feeding machine to melt it in the depth of the molten steel. The use of calcium iron cored wire can play the role of deoxidation, desulfurization, and removal of inclusions.
  • The use of calcium iron alloy cored wire can fine-tune the composition, improve the yield of metals and rare earth elements, and ensure the stability of the composition. It can effectively reduce the number of precious metal elements added and reduce the cost of refining steel.
