摘要： The invention relates to a method for measuring the cooling curve of a test sample of metal or a metal alloy, in particular cast iron or cast steel, for the differential thermal analysis in which the difference of the cooling curve of the test sample of a fixedly given comparative curve which satisfies Newton's law of cooling (U=U.sub.0 .times.e.sup.-t/RC, the U.sub.0 parameter being the maximum value at the point in time t=0 and the RC parameter being the time constant) is formed, said comparative curve being brought to coincidence with a section of the cooling curve of the sample by adjusting its parameters so that the difference can then be formed between the adjusted comparative curve and the cooling curve.

摘要： In apparatus for picking up a test sample of molten metal or metal alloys and measuring the cooling curve of said sample, comprising a sample receptor and an optical conductor leading from the receptor to a transducer, the receptor is a small, open ended refractory tube having a cavity for receiving the molten sample arranged at the free extremity of a lance with the optical conductor contained within the lance and terminating at the cavity in said receptor and a barrier is disposed between the cavity and the optical conductor, the barrier consisting of a heat resistant, highly thermally conductive material of such quality as to cause the material of the melt sample which is picked up to adhere thereto.
