The most important factor influencing the casting and rolling performance of steel is the location of the high-melting-point calcium (Al2O3) inclusions that are present in the melt of steel. This solid aluminate can hinder nozzles and be difficult to eliminate. This issue can be resolved through our 100% calcium wires.
Once the cored wire has been in the liquid steel, it can transform these solid aluminate inclusions to CaO-Al2O3 inclusions, which are small in dimension and are nearly round in their shape. This alters the pattern of these inclusions in the molten steel and improves the performance of rolling and casting. The aluminate present in the melting of the steel is liquid, and reduces blockage of the casting nozzle.
The procedure is suitable for any molten aluminum steel. The process is possible because of the lower melting point and the superior level of purity in calcium alloy. It's the most efficient method of introducing Calcium into the steel in molten state and make sure that it exerts an impact on the process of desulfurization and deoxidation processes in addition to reducing the clogging of caster nozzles due to the development of inclusions in alumina.
The extruded Calcium rod used to make our pure Calcium Cored Wires allows for more metallurgical results than standard Ca powder-cored Wires. The melting properties of powdered calcium and solid calcium are different. The pure calcium wires we use are hermetically sealed in a thick and weld-on jacket. This allows the wires to penetrate deeper into the steel, allowing enough ferrostatic force to prevent evaporation and preserve the Calcium in liquid form. The amount of calcium needed for similar or more effective results is cut by an enormous amount. This will boost your efficiency, and save you costs on treatments for Calcium.
