Title
Temperature Behavior of Continuous Casting Slabs for the Hot Direct Rolling Process
강신언Shin Eon Kang, 윤우석U Sok Yoon
Abstract
In order to realize hot direct rolling(HDR) process, it is prerequisite to produce high temperature slabs by the continuous casting process. For this purpose, two-dimensional mathematical model has been used to estimate the change in slab temperature from the meniscus to the edge heater. The secondary cooling patterns have been modified to obtain slabs with high temperature via slab surface temperature measurements and thermal analysis of the slabs. The effect of the thermal insulator on slab temperature has been studied to find out the optimum condition for obtaining slabs with higher temperature. As means to investigate the temperature profile of slab in the edge heater and to validate mathematical model, temperature of slab with embedded thermocouples was measured in the edge heater. Based on the above temperature controlling methods, the HDR has been operated successfully.
