GENERAL CHARACTERISTIC AND FEATURES OF BLOW DEVICES FOR
HIGHER SCAVENGING OF BATH OF STEEL-SMELTING AGGREGATE BY
OXYGEN

Zaporozht state engineering academy

The analysis of literary sources is executed in part of structural features of blow
devices for scavenging of bath of steel-smelting aggregates by oxygen. Absence of
synonymous recommendations is set in relation to the choice of construction and optimal
expense of oxygen, given on sesvenging and after-burning of monomonooxide of carbon,
distinguished from bath of steel-smelting aggregate. An analysis specifies on the necessity
of development of new structural decisions of oxygen lance, which will allow to combine
dignities of the known constructions and promote efficiency of after-burning of
monomonooxide of carbon in the cavity of steel-smelting aggregate with the improvement
of thermal balance of melting as it applies to the real productive conditions.

Keywords: steel-smelting aggregate, sesvenging of bath, blow devices, afterburning
of carbon monooxide, heat balance, power resources
