PURPOSE: A pusher heating furnace is provided to minimize a decrease in the temperature of a slave, and to rapidly increase the temperature of the slave. CONSTITUTION: A pusher heating furnace comprises a slave (110), a preheating zone (120), a heating zone (130), and a fracture zone (140). The slave is continuously supplied at a unit length, and moves according to the operation of a charging pusher. The preheating zone is placed on the moving route of the slave, and pre-heats the slave so that the slave is not suddenly exposed to the high temperature. The heating zone maintains the temperature of the slave at predetermined temperature. The fracture zone comprises a upper extended part and a plurality of heating units. |
