Introduction
Custom-designed, lime-based desulfurizers for efficient steel
refining in the ladle are engineered to provide cost effective
desulfurization during and after furnace tapping. This is achieved by
the immediate production of a molten slag with an increased
desulfurization potential. The rapid fluidization of the entire ladle
slag increases the absorption of sulfur and non-metallic inclusions
throughout each stage of ladle refining. These custom-designed products
are available with specified levels of metallic aluminum or silicon to
improve the efficiency of the desulfurizing process. This allows the
specified sulfur levels to be reached within the time required.
Pre-melted mgo is also provided to generate rapid and ongoing refractory
protection.
Advantages
1. Do not need extra expense of investing equipment
2. Using out furnace desulfurization in tapping course
3. Easy using, economic, effective and high desulfurization rate
4. Can be used before smelt-fast tapping- external furnace refining short flow steel-making technics
5. Used in intermediate frequency furnace
