PREDICTING METHOD OF PHASE TRANSFORMATION TEMPERATURE AND MANUFACTURING METHOD OF HIGH CARBON STEEL USING THE SAME

摘要

In the hot rolling process, a phase transformation temperature prediction method and a steel manufacturing method using the same, which can easily calculate a phase transformation temperature by collecting temperature change data, are disclosed. Phase transformation temperature prediction method according to the present invention comprises the steps of (a) collecting the temperature data of the specimen according to the cooling time using a thermocouple while cooling the hot-rolled specimen; And (b) using the collected data, analyzing the phase transformation temperature at which the change of the cooling rate is the greatest.
