The effects of deoxidation practice on the quality of thin foil low-carbon steel
In converter steelmaking of AISI 1006 steel for thin foil products, two tapping practices are used with respect to deoxidation: silicon and manganese additions during tapping and aluminum deoxidation after complete tapping (“semikilled practice”) and aluminum deoxidation during tapping,...

| description | In converter steelmaking of AISI 1006 steel for thin foil products, two
tapping practices are used with respect to deoxidation: silicon and
manganese additions during tapping and aluminum deoxidation after complete
tapping (“semikilled practice”) and aluminum deoxidation during tapping,
“fully killed practice”. There is a perception that the semikilled practice
may be more economical and result in the same quality as the fully killed
practice. In this work, the effects of the tapping practice on steel quality
and cost variables were evaluated for thin foils of AISI 1006 steel. Oxygen
and aluminum content, aluminum and ferro-alloy yield, the type of alumina
inclusions formed, and the quality of the steel during thin foil rolling
were evaluated and compared. It is shown that the fully killed practice
leads to less reoxidation from slag, lower soluble oxygen, and lower total
oxygen at the caster as well as better morphology of the remaining alumina
inclusions than the semi-killed practice. Thus, the higher quality of the
steel produced via the fully killed tapping deoxidation practice when
compared with semi-killed tapping is demonstrated. It is also shown that a
complete cost evaluation favors this practice in the case of products rolled
for tin foil production. |
