Precise control on inclusions is of great importance for improving steel quality. In secondary refining, three types of inclusion are generally observed in Al-killed steel: Al 2 O 3, MgO·Al 2 O 3 spinel, and CaO–Al 2 O 3 type. Many researchers have reported on inclusions transformed in the routine of Al 2 O 3 → MgO·Al 2 O 3 spinel → CaO–Al 2 O 3 during secondary refining in Al-killed


2000-6-12 · The use of tuyere injectant such as powdered fuel (120 kg/t) or oil (60 kg/t) further reduces the coke consumption of the furnace and so the cost. Below the tuyere zone, where the temperature is highest, the molten material collects on the furnace hearth where the liquid iron (pig iron) separates from the slag by difference in density.


Among other disadvantages, the nitrous oxide emission from this process (300 kg of N2O per ton of adipic acid, measurably contributes to global warming and ozone depletion. Therefore, the development of a more efficient adipic acid production process that is less damaging to the environment is an important subject in chemical research.
