Title: Top-blown oxygen converter control - changes lance distance or oxygen rate depending on iron droplets amt. in slag
Inventor: MAHN GUSTAV DR ING
IPC: C21C5/30
Filed: 1976-11-13
Abstract: The refining operations of pig iron on a top-blown oxygen process are controlled as a function of the measured amt. of iron droplets in the slag. The variables which are charged in accordance with these readings are the oxygen lance distance and/or the oxygen flow rate. This speeds up the refining operations and results in uniform steel quality from charge to charge. The refining operation can be automated and the droplet content can be optimised. The iron/slag/gas emulsion in the converter represents the dielectric for the oscillatory circuit. Charges in the iron droplet content cause an unbalance in this circuit and this is converted by the computer into corrective actions.
