Calculation method of sintering temperature history

摘要

PROBLEM TO BE SOLVED: To provide a method for calculating a temperature history during sinter use easily, using a parameter which can be actually measured relatively easily even in carbonaceous materials having significantly different burning quality, and reducing calculation load compared with that in a conventional method.SOLUTION: Provided is the calculation method of sinter temperature history comprising: a step for measuring ignition temperature Tof a carbonaceous material having a grain size of 1-3 mm; a step for deciding reaction initiation temperature Tbased on the ignition temperature Tof the carbonaceous material; and a step for deciding a reaction speed factor Kof the carbonaceous material based on a step-wise function using the reaction initiation temperature T.
