The steel industry is a large user of Pure Calcium Cored Wires for Iron Making. It is used mainly in the processes of De-oxidation and Desulphurization. It is used to improve the quality and reduce the production cost of liquid steel. The core of the sheath is a cold rolled, low carbon steel. It is injected into the molten steel through a special designed wire feeder. The injection speed must be high enough to melt the sheath in the molten metal within seconds of entering the ladle.
The main purpose of the calcium treatment is to deeply reduce the oxygen content, sulfur content and inclusions in the molten steel and modify their composition. The calcium process is also an important step in the refinement of molten stee in iron and stee enterprises, which is commonly called ladle metalurgy. The metallurgical processes used in ladle-furnaces for calcium treatment are usually carried out through the spraying or feeding into molten steel of powders or core wires.
Compared with conventional calcium containing cored wires, a solid pure calcium cored wire has many advantages: its specific surface area is much smaller, so the metal calcium is less easily oxidized in the high temperature of the steel melt; it can effectively control the pollution of molten steel by other oxides, such as iron and silicon in the core of traditional powder cored wires, and it can significantly reduce the consumption of calcium per ton and avoid nozzle clogging in continuous casting steel.
In the process of melting steel, a significant amount of calcium is required to control the reaction between slags and molten metal. It can be added directly to the molten iron in a hot-casting facility using cored wires or sprayed with an airgun into the slag. Spraying can generate a lot more dust than the addition technique, but it is also inefficient. Cored Wires are an efficient and economical way to deliver calcium in the molten Steel, especially for large-scale steel production with a complex structure or high iron content.
Anyang Huatuo is a manufacturer of cored steel wires. It has five production lines. These include three lines of powder wrapped cored wiring such as ferro silicon magnesium cored, calcium iron cored and calcium silicon cored. There are two lines for solid cored cable, such a pure calcium cored. The diameter of the cored wire can be customized according to customers' demands. The core's purity can reach 97%, and is very popular among our customers. Contact us for more details. We are looking forward your cooperation!
