DeCAL LD (Calcium Aluminate Based DS Reagent)

Introduction

DeCAL-LD is engineered to provide homogeneous composition of Calcium Aluminate Flux which refines steel in ladle in secondary metallurgy. DeCAL-LD is specifically designed to meet the requirements for desulphurization, prevention of reoxidation and non metallic inclusion absorption without any adverse effect on ladle refractory. DeCAL-LD facilitates the formation of slag. Optimises the composition of the slag. Maximises the efficiency of the steel refining process with
*High Quality.
*Improving Productivity.
*Cost Effectiveness.

Application

DeCAL-LD is so engineered to use in ladle in secondary metallurgy. This product is added to the ladle before or during or after tap at the steel making furnaces or during or after processing at intermediate treatment facilities. Addition rate varies from 4-8 Kg per ton of liquid steel depending upon parameters.

How it works

After adding in ladle DeCAL-LD becomes an oxidised semi liquid / liquid which floats on the surface of liquid steel and absorbs the non metallic inclusions and impurities consisting mainly of sulphur.

Advantage

● Optimum slag fluidity and thermal insulation.
● Reduction of heat losses by covering molten metal.
● Elimination of reoxidation of steel from atmospheric oxygen.
● Provides non metallic inclusion absorption without adverse effect on ladle refractory.
● Desulphurisation and deoxidation of steel.
● Dust free eco friendly use.
