ABSTRACT:
The invention relates to a method for determining the carbon content of steel melts by thermal analysis by determining on a cooling curve the arrest point occurring during the liquidis phase change, the carbon content being determined by the arrest point temperature in conjunction with the iron-carbon diagram. In the method, the temperature difference is measured between two arrest points occurring during the liquidus-phase change and a phase transformation and the measured temperature difference is used to determine the carbon content in conjunction with the iron-carbon-diagram.
