Abstract (en)
[origin: WO2016050399A1] The invention relates to a method for determining the point in time of ignition during an oxygen blowing process, in particular during the basic oxygen process, in a converter (1), wherein an oxygen amount value (110) for the amount of the oxygen blown and a waste gas temperature value (20) for the current waste gas temperature in the waste gases resulting from the oxygen blowing process are determined, and the point in time, at which a predefined oxygen limit value for the amount of oxygen and, at the same time, a predefined waste gas temperature limit value in the waste gas are reached, is defined as the point in time of ignition. The invention also relates to a device which is particularly suitable for carrying out the method.
