High Quality Calcium Treatment in Steel Mills

In the liquid steel refining process, calcium treatment is a highly efficient technology of final clean steel refining process
In the liquid steel refining process, calcium treatment is a highly efficient technology of final clean steel refining process,which is strict in the morphology of inclusions and quantity. Calcium treatment,not only has the function of deoxidation , desulfurization ,changing the morphology of inclusions and increasing the continuous castability, ( the purity of steel and the continuous castability are increased remarkably.) but also be used in micro adjustment, increasing ca yield ,stable production operations, improving product quality and  reducing production cost.

The contrast between solid ca cored wire and caSi cored wire in calcium treatment,which used in the refining process: 
Calcium treatment can reduce the qutity of sulphide impurities,change its composition and properties, improve steel cleanliness, the uneven phenomenon of calcium silicon powder can cause  an unstable yield in practice .  Also the  happening   of  oxidizing reaction is influenced by  the contact area .Due to calcium silicon powder's  large involvement ,  the oxidizing reaction is much more likely to  happen than solid ca cored wire.

On the premise of ascension and stable quality .  Replacing caSi cored wire with solid ca cored wire can better to reduce costs. 
In recent years , some steel manufactuers used solid ca cored wire for calcium treatment in the refining process........
