Theoretical analysis of the processes and material balance of the steel deoxidizers (calcium and aluminium) at all stages of ladle treatment showed that although << excessive >> amount of calcium during casting and crystallization of metal in the mould (weight of the ingot equaled 3.
Crystal-chemical structure of multiphase oxide inclusions is determined by physical-chemical state of the pool, sequence of introduction of the deoxidizers, and interaction of dissolved in the metal elements.
holding of heats in the furnace after final deoxidizers have been added;
The usual method to reduce the oxygen content is the addition of a final deoxidizer that has a greater affinity for oxygen than carbon, and that forms a solid or liquid oxide product.
Other special deoxidizers such as calcium (Ca) silicon (Si), Ca manganese Si, Ca silicide, and ferrotitanium may be added with the Al.
The relative affinity of deoxidizers for the elements of interest is shown in the table on p.
Further, there may have been a slight reduction in recoveries of the final deoxidizers, but statistical confidence was low.
