Cored wire usage

Calcium treatment Aluminum-killed clean steel
In case of Al-killed grades, the steel bath contains high melting point Al2O3 inclusions which can lead to nozzle clogging at the continuous caster, poor transverse mechanical properties after rolling, bad resistance to HIC and bad machinability. The addition of Ca during ladle refining transforms Al2O3 into(CaO)x(Al2O3)y which has a low melting point and also remains globular during rolling, thus eliminating the above problems.
Trimming additions
Due to the high and stable recovery of additions practiced by way of cored-wire, a very accurate and reproducible steel chemistry can be achieved which in turn permits to optimize the mechanical properties and / or heat treatment as well as eliminate rejection or downgrading of heats out of the chemistry specification. Most popular for this purpose are cored-wires containing carbon, sulfur, manganese, FeTi

Cored wire purpose

General advantage of cored wire addition
During cored-wire injection, the content powder is released close to the ladle bottom, far away from oxidation sources (slag, air) and under high ferrostatic pressure. This leads to a better recovery compared to traditional lump or powder additions, especially for elements which are highly oxidizable have a high vapour pressure and / or a low density.
Phase-diagram
CaSi wire addition to Aluminum- Silicon deoxidized grades permits to achieve very plastic inclusions of the Anorthite type which are favourable to deep drawing (in wire rod for instance) and machinability.

A limited Ca or CaSi wire input can solve Ti02 nozzle clogging problems at the CC on Titanium stabilized stainless steel grades.

CaSi Wire addition on Silicon- Manganese deoxidized steels with a low Mn/Si ratio can avoid nozzle clogging problems created by high melting point Manganese-Silicates and limit the scum formation which is detrimental to surface quality.

Company introduction: It is my great pleasure to address our precious customers of SeoKang Metals Co., Ltd. in this new newly designed homepage.

It has been almost twenty years since we engaged in the business of manufacturing steel products. But we are always in the same spirit as when we were starting. Started in 1986 as SeoKang Co., Ltd, we have produced recarburizer, which are essential raw materials in steel making industry, and also developed cored wires for the first time in the nation.

Thanks to outstanding performance we have been successful in positioning SeoKang Metals Co., Ltd. as a primary supplier in the business, both at home and abroad. Our products are very competitive in price and quality, providing our customers with pleasure and satisfaction. Encouraged by your continued supports, we are doing our utmost best to produce better products more cost-effectively.

We look forward to your continued patronage and encouragement.

Thank you.
