Abstract

Abstract

Based on the walking-beam-type reheating furnace in a certain steel plant, the TA1 titanium billet in the furnace was taken as the research object, and the mathematical model of heat transfer and the finite element model of heating process were established to study the temperature distribution of titanium billet in the heating process. The effects of furnace temperature and inlet temperature of titanium billet on the maximum temperature difference of cross section in the heating process of titanium billet were studied, and the effects of preheating zone temperature and heating zone (I) temperature on the heating time to meet the requirement of tapping temperature of titanium billet core were studied. The results show that the maximum temperature of the titanium billet is always at the corner of the end face and the minimum temperature is at the core of the titanium billet when the titanium billet is heated by the preheating zone and the heating zone (I), while the corner temperature is the lowest after the soaking zone. When the preheating temperature increases by 5 ℃, the maximum section temperature difference increases by 1～2 ℃, and when the titanium billet temperature increases by 50 ℃, the maximum section temperature difference decreases by 3～8 ℃. When the temperature of preheating zone increases by 10 ℃, the time for the core to meet the requirement of furnace discharge reduces by 1～2 min. When the temperature of heating zone (I) increases by 10 ℃, the time for the core to meet the requirement of furnace discharge reduces by 4～6 min.
