Desulfurizer

Desulfurizer is the desulfurization dregs serious developed by our company for adapting out furnace refining, which not need extra expenses of investing equipment when using it. Used as out furnace desulfurization in tapping courses, it has the advantages of easy use, economic, effective and high desulfurization rate,  which may be widely used before smelt-making techniques, and the desulfurization rate may be as high as 40~80%. The product has good desulfurization effect and has evident effect of reducing the cost of steel-making.
Method of use:

1. Pre add 2/3amount at steel ladle bottom steel flow striking position

2. The rest 1/3 amount is added in with steel flow

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
