Core wire is a composite material. It is made by crushing various additives (such as deoxidizers, desulfurizers, alloys, etc.) into a certain particle size and then wrapping them with steel strips, with any length possible. The characteristics of core wire include: all the core materials are melted alloys, with few inclusions, stable reactions, high absorption rate, and can effectively shorten the smelting time and precisely control the composition. This technology is widely used in modern steel mills and foundries.
