Abstract

PRETREATMENT, as the term implies, is the treatment or conditioning of molten pig iron before it is charged into a steelmaking furnace with a view to improve the speed and quality of steel production. Steelmaking is funda-mentally an oxidation process followed by varying degrees of reduction (deoxidation) of the over-oxidized metal. The metallurgical load during steelmaking in the openhearth furnace can be appreciably reduced and hence the speed of production appreciably increased if some of the elements in the iron puticulnly Si and P, could be partially remo-ved. The oxidation cf a large part of Si and to some ext-ent of P in the molten pig iron, before it is charged into a basic OH furnace has therefore engaged the attention of many steelmakers.
