Since the temperature of the furnace head at both ends of the coking chamber of the coke oven changes suddenly when the furnace door is opened, it is necessary to select high alumina products with good thermal shock resistance and high load softening temperature. At present, high-quality High-Alumina Jamb Brick from Yixing Dingshan Refractory Material are recommended.
