LANCE AND METHOD FOR DETERMINING REACTION DATA OF THE COURSE OF A REACTION

摘要

A lance and a method determine reaction data of the course of a reaction, in which a reaction gas is top-blown by at least one lance onto a metallic melt in a metallurgical vessel and measured data are determined in this way, reaction data for the course of the reaction are determined as a function of these, where the lance for determining measured data blows out a gas which is conveyed separately from the reaction gas through at least one outlet opening of at least one measuring conduit. The lance for determining measured data blows out the gas which is conveyed separately from the reaction gas laterally through at least one outlet opening of at least one measuring conduit and the internal pressure of at least one gas bubble of this gas formed at this outlet opening of the respective measuring conduit is measured.

1. Method for the determination of reaction data of a reaction sequence, in which a reaction gas (4) is top-blown by means of at least one lance (1) onto a metallic melt (3) in a metallurgical vessel (2) and simultaneously measured data are recorded, as a function of which reaction data about the reaction sequence are determined, wherein the lance (1) for the recording of measured data blows out a gas being conveyed separately from the reaction gas (4) via at least one outlet opening (12, 13) of at least one measuring line (9, 10), wherein the lance (1) for the recording of measured data blows out the gas being conveyed separately from the reaction gas (4) laterally via at least one outlet opening (12, 13) of at least one measuring line (9, 10), wherein the internal pressure of at least one gas bubble (14, 15, 19) formed at this outlet opening (12, 13) of the respective measuring line (9, 10) is measured.
