Abstract

The invention discloses a converter tapping judging method. The converter tapping judging method comprises the steps of setting the steel type category, and according to the steel type category, setting a standard value; selecting a judgment mode; when smelting abnormity appears in the smelting process, selecting the manual judging mode; when the smelting process is normal and TSC chemical test data, and TSO measuring data meet the standard value, automatically judging tapping; when the TSC chemical test data, and the TSO measuring data do not meet the standard value or when TSC chemical testdata meets the standard value and the TSO measuring data does not meet the standard value, selecting the manual judging mode; when the TSC chemical test data does not meet the standard value and the TSO measuring data meets the standard value, and when the TSO chemical test data meets the standard value, automatically judging tapping; if not, selecting the manual judging mode; and through the converter tapping judging method, according to the actual smelting condition, different tapping judging modes can be selected, the converter taping judgment process is simplified, and the converter waiting time and the converter end point period can be shortened.

Description

technical field [0001] The present application relates to the technical field of iron and steel smelting, in particular to a method for judging steel tapping in a converter. Background technique [0002] The molten steel needs to be judged before tapping the converter, and only when the temperature and composition of the molten steel meet the requirements can the steel be tapped. [0003] Modern large and medium-sized converters are equipped with a sub-lance system. The composition and temperature of the end-point molten steel can be accurately measured and tested through the TSO probe, and the steel can be tapped after the measurement data and test data are qualified. [0004] However, the traditional sub-lance operation steps are TSC measurement, sampling-testing-TSO measurement, sampling-testing-judgment-tapping. This kind of judgment procedure needs to wait for the TSO measurement to be completed and the steel sample composition test to be completed before the tapping ca...
