Performance:Silicon and calcium can offer great affinity to oxygen, and calcium also offers great affinity to sulfur, thus the products of sulfur deoxidizer are easy to float and discharge. Therefore, it can improve the performance of steel obviously, including the plasticity of steel, impact toughness and mobility. As to the production of cast iron, it also plays a key role in the fields of deoxidation, desulfurization, denitrification and silicon-increase.
