Beyond the basic purification function, the improvement of macroscopic properties of steel by seamless calcium wire is also remarkable. The contribution from improving processing plasticity to enhancing surface smoothness is directly related to the market competitiveness of the final product.
The value of seamless calcium wire is fully reflected in the subsequent rolling, forging, and processing of steel.
1. Empower excellent processing performance
Hard oxide inclusions (such as alumina) in steel are like "microcracks" hidden inside the material, which can easily become stress concentration points during processes such as cold rolling, hot rolling, or forging, leading to steel cracking or edge defects. The addition of seamless calcium wire can transform these high melting point and harmful inclusions into low melting point, spherical calcium aluminate composite inclusions.
This "inclusion denaturation" treatment makes these tiny particles more prone to deformation rather than breakage during rolling, significantly reducing their damage to the continuity of the steel. The direct result is a significant improvement in the ductility and plasticity of steel, making it less prone to cracking during harsh processing such as deep drawing and bending, and significantly increasing the yield of finished products.
2. Create a smooth surface quality
The surface defects of steel, such as pitting and peeling, often originate from large inclusions that have not been removed from the molten steel. Seamless calcium wire reduces the quantity and size of these inclusions from the source through deep deoxidation and inclusion morphology control. This greatly reduces the probability of defects forming on the surface of the steel during subsequent continuous casting and rolling processes, thereby obtaining a high-quality surface with higher smoothness and more uniform quality, meeting the stringent requirements of high-end users such as automotive panels and home appliance casings for surface quality.
