Steel cored wire
Round cored wire consists of a long, slender, continuous tubular strand coiled into a large, tightly wound cylindrical spool. The spool itself is cylindrical in shape. solid calcium cored wire has two layers: the outer layer is a tubular casing formed by coiled steel strip, while the inner core can be filled with various alloy powders—such as calcium silicate, calcium iron, or aluminum powder—or solid metal. The seamless calcium ferro cored wire is fed into the molten steel via a wire feeder. Most modern steel mills use core wire for deoxidation and desulfurization to improve molten steel quality. Seamless calcium ferro cored wire enhances steelmaking efficiency while increasing alloy recovery rates.
Core Wire Addresses the Pain Points of Traditional Charging Methods
In the past, steel mills added metallurgical additives such as alloy powders by sprinkling them directly onto the surface of the molten steel or by dropping lump-shaped pieces into the molten steel, which resulted in uneven reactions with the molten steel.

In the past, steel mills added metallurgical additives such as alloy powders by sprinkling them directly onto the surface of the molten steel or by dropping lump-shaped pieces into the molten steel, which resulted in uneven reactions with the molten steel.
Powdered materials tend to float on the surface of the molten steel and fail to penetrate deep into the melt, resulting in incomplete desulfurization and deoxidation within the steel.
Powdered or lump-form metallurgical additives generally generate significant dust, leading to poor working conditions for workers and high levels of pollution.
Highly reactive alloys are prone to oxidation upon contact with air, resulting in low utilization rates.
Flux-cored wire addresses these challenges. In this process, an alloy core is encased in steel strip and fed through a wire feeder to sink deep into the molten steel. As the wire gradually melts, the core material is released into the molten steel, ensuring a uniform and thorough reaction between the alloy and the molten steel. This improves the stability of molten steel quality, increases element recovery rates, and makes the production process more environmentally friendly by eliminating dust.
