The use of core wire in steelmaking is a very important and economical way to add high-quality Calcium Silicon into the liquid phase of the steel melting process. Our specialised wires are made from silicon calcium of high purity and can be produced in a range of sizes and grades to meet customer needs. This product has many important functions in the steelmaking process; it accurately controls the composition of molten iron, plays a role in purifying and changing the properties and forms of some inclusions, improves the casting state of the molten steel, and enhances its quality.
Compared with conventional metal calcium wire, the cored wire made by Bozel has higher calcium recovery rate, reducing material waste and lowering the production cost of pure calcium. The cored wire also offers a stable market demand and supply relationship with low fluctuations in price, which is an important advantage for fixed steel and iron enterprises.
The steel industry requires that cored steel wires are used in the melting of liquid metal. The low density of pure calcium and its high boiling point make it difficult to add to molten steel. Calcium Silicon, however, has a greater affinity for sulfur and oxygen than aluminum. Cored wires allow the addition to molten iron of pure Calcium Silicon, which improves its quality and reduces the amount re-melting. It also reduces nozzle clogging caused by aluminum deoxydation.
It is crucial to know how to feed cored wires correctly. This is the only way you can achieve the best metalurgical results. Specifically, it is crucial to control the feeding speed and rhythm to ensure that the solid calcium wire can reach an optimal depth in the molten iron and avoid premature oxidation. It is important to also understand the impact that the slag's composition has on the release and oxidation of calcium.
Bozel is one of the largest manufacturers of pure calcium cored wire in the western hemisphere, and is committed to supplying premium products to global customers in a variety of sizes and packaging options. We also provide comprehensive technical support for cored wires. Our team of experts is available to answer your questions and help you find the right solution for your steelmaking needs.
