Abstract

Hot stove is a thermal heat regenerator to produce and supply constant hot air to blast furnace. The present demand of increased hot metal productivity through blast furnace route requires high hot blast temperature, more than 1200 °C, and it requires to optimize and upgrade the quality and design of refractory. Thus, design of stove and their checkers have undergone a major change and demand installation of superior-quality refractories. Advantages in changed design and upgrade refractory quality from alumina dome to silica, installation of ceramic burners are extravagantly explained in this chapter. Latest development in stove design is top combustion stove that can deliver hot air more than 1300 °C; in obvious this operational feature has economic benefit over conventional one. Detailed discussion has been done on critical refractory application in those type of stoves that eventually help to generate knowledge on how one can use effectively hot blast more than 1300 °C for as large as 5000 m3 blast furnace.
