Title: Stirring molten metal covered by nonmetallic reagents - suitable for rapid desulphurisation of crude iron
Inventor: OESTBERG JAN-ERIK
IPC: F27D27/00
Filed: 1976-01-24
Abstract: A stirrer is partly or completely immersed in the system and rotated; and the surfaces of the stirrer are not perforated in the direction of rotation. The novelty is that a high and uniform stirring energy is obtd. by >=1 of the steps:- (a) the direction of rotation of the stirrer is reversed one or more times, (b) the rotation of the stirrer is stopped one or more times, (c) the r.p.m of the stirrer is altered in accordance with a programme during the operation and (d) the vertical height of the sitter is altered, viz. either lowered to create a sec. vortex, or raised so a free stream of the upper reagent phase is formed and drops onto the melt. Used e.g. in removal of sulphur from crude iron, the operation can be completed in 5 minues whereas 8 mins were previously required. It was formerly necessary to use soda or CaC2 for desulphurisation but now CaO can be used which reduces both cost and environmental pollution.
