Core wire is a linear composite material used in steel smelting to precisely adjust the composition of molten steel. Its typical structure is made of low-carbon steel or low-alloy steel strip, which is tightly encapsulated with a specific ratio of alloy powder through cold rolling wrapping process.
Outer steel strip: sturdy protective shell
The outer metal skin is usually made of low-carbon steel or low-alloy steel strip, which is chosen based on its two core advantages:
Excellent thermal conductivity: ensuring rapid melting and release of contents after pouring molten steel.
Excellent plasticity: easy to roll and package at high speed, forming a dense structure, effectively preventing internal alloy powder from being damp or oxidized during transportation and storage.
Core Powder: Customized Refined Core
The core of core wire lies in its internal alloy powder, which is not a fixed formula, but a mixture that can be flexibly customized according to smelting goals:
Diverse components: can be various metal and non-metal elements such as silicon calcium, calcium iron, carbon powder, etc.
Clear function: mainly used for deep deoxidation, desulfurization, fine adjustment of composition, and transformation of inclusions in molten steel, it is a key material for improving the cleanliness and comprehensive performance of steel.
Core values: precision, efficiency, and economy
Through this innovative core wire form, precise feeding of alloy additives, high yield, and controllable reactions have been achieved, ultimately achieving the goal of purifying molten steel, improving steel quality, and reducing smelting costs.
If you have specific alloy powder compositions or target steel grades that need to be matched, we can provide you with more targeted customized solutions for core wire.
