Ferroalloy cored wire for steel industry
Core wire technology is a method of ladle refining that has emerged in recent years and is widely used in modern steelmaking wire feeding techniques. Steel refining cored wires consist of alloy powder encased in a steel strip. Using specialized feeding equipment, the core wire is inserted into the desired position. Once the outer layer of the core wire melts, the core can fully dissolve at the target location and undergo a chemical reaction, effectively preventing reactions with air and slag. This improves the absorption rate of metallurgical additives, alters the morphology of inclusions in molten steel, and effectively enhances the quality of steelmaking and casting products. Flux-cored wire serves as an auxiliary tool in steelmaking; through ladle refining, it significantly improves the properties of molten steel, which is highly beneficial for companies seeking to reduce steelmaking costs.
Silicon-calcium core wires are a type of wire-shaped material used in the refining of molten steel. They are composed of a core layer of silicon-calcium alloy powder and a thin steel strip wrapped around the outer surface of the core powder layer. Once the outer steel strip of the silicon-calcium core wire enters the ladle and melts, the underlying powder layer is exposed and comes into direct contact with the molten steel to undergo a chemical reaction. This effectively achieves the goals of deoxidation, desulfurization, and inclusion removal, thereby improving the quality and performance of the steel. By feeding silicon-calcium cored wire into the molten steel, the high-melting-point alumina inclusions produced by aluminum deoxidation can be converted into low-melting-point, low-density calcium aluminate inclusions. At the same time, this process reduces the number of sulfide inclusions, alters their composition and properties, purifies the molten steel, and improves steel quality.
The characteristics of ladle treatment cored wires include:
1. They facilitate the adjustment and control of the content of easily oxidizable elements and trace elements, significantly improving alloy recovery rates, reducing smelting costs, and shortening smelting time. They also enable precise control of composition.
2. They purify the molten steel and partially alter the properties and morphology of inclusions, thereby improving the quality of the molten steel and enhancing casting conditions.
3. Core wires are available in two types: internal-extraction and external-discharge. The mechanical equipment required for feeding is simple and reliable, occupying minimal floor space; in particular, internal-extraction core wires are better suited for use in confined spaces.
