### Numerical investigation on heating process of Ti/Steel composite plate in a walking-beam reheating furnace

**ABSTRACT**

A two-dimensional numerical model was established to calculate the temperature distribution of Ti/Steel composite plates in a walking-beam reheating furnace by using the central difference method. The heat transfer characteristics of Ti/Steel composite plates in a walking-beam reheating furnace were studied. The influence of heating time, heating temperature, and different interface contact conditions in different heating zones on the temperature distribution of Ti/Steel composite plates was studied. The results indicate that the maximum error between the calculated temperature and the measured temperature is 5.4%, proving the correctness of the numerical model. When heating continues, the plate cross-section temperature difference first increases and then decreases, with the maximum value of the temperature difference appearing in the preheating zone. There is a temperature inflection point at the interface between titanium plate and steel plate. The larger the proportion of vacuum zone in interface contact, the lower the plate center temperature.
