Title:
LANCE AND METHOD FOR DETERMINING REACTION DATA OF THE COURSE OF A REACTION
Document Type and Number:
WIPO Patent Application WO/2014/153585
Kind Code:
A3
Abstract:
A lance (1) and a method for determining reaction data of the course of a reaction, in which a reaction gas (4) is blown by means of at least one lance (1) onto a metallic melt (3) in a metallurgical vessel (2) 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 (1) for determining measured data blows out a gas which is conveyed separately from the reaction gas (4) through at least one outlet opening (12, 13) of at least one measuring conduit (9, 10), is disclosed. To be able to determine the course of a metallurgical reaction particularly accurately, quickly and reliably, it is proposed that the lance (1) for determining measured data blows out the gas which is conveyed separately from the reaction gas (4) laterally through at least one outlet opening (12, 13) of at least one measuring conduit (9, 10) and the internal pressure of at least one gas bubble (14, 15, 19) of this gas formed at this outlet opening (12, 13) of the respective measuring conduit (9, 10) is measured.
