2133333 9320965 PCTABS00027 The invention relates to a method for determining the carbon equivalent (C.E.) of structure modified cast iron melts, and to the use of this method for adjusting the composition of a structure modified cast iron melt. The method is based on the introduction of one or more pieces of iron of low carbon content into a sample container. The iron piece or pieces has/have a size such that the iron piece/pieces will not melt completely when the sample container is filled with melt, which is allowed to solidify. The temperature of the melt is recorded as the melt solidifies. When practicing the method, there is obtained a well-defined absolute temperature as the temperature passes the .gamma.-phase liquidus line, or a temperature difference in relation to the eutectic temperature of structure modified cast iron of a closely similar type. The carbon equivalent is determined on the basis of a phase diagram applicable to this structure modified cast iron. The carbon equivalent of the melt is adjusted by adding carbon and/or silicon or iron of low carbon content.
