Refractory for Coke Dry Quenching Equipment

Coke dry quenching equipments (hereinafter called CDQ furnace) is a kind of equipment in which coke dry quenching technology is involved to reclaim coke and release heat energy, and could be used to improve the quality of coke and reclaim red coke and make heat energy to the effect of energy saving and environmental protection so that blast furnace will operate more efficiently. And this technology is an outstanding environmentally protective one in national industries. A coke dry quenching equipment is composed of a stove door, a cone body, a pre-storage room, a flue and cooling room, in which the cooling room, in which the cooling room and flue will have effect on the service life of CDQ furnace. And the flue will break mainly due to thermal stress from the different reaction of each part of the flue to the change of temperature and high-temperature mechanical peeling from the uneven load of refractory materials, while the cooling room will be so for wearing and the change of air flow. On the basis of domestic technique of refractory material for CDQ stove, this company has developed series of senior Mullite-SiC Series and cement for match use, for the key parts of the CDQ stove, such as flue and cooling room, etc with the main breakage cause and service condition of refractory materials for CDQ stoves as a reference. What's more, the physical and chemical indexes of the above-mentioned goods have achieved advanced domestic level. And the above-mentioned goods could be matched with other products of this company for CDQ so that the service life of CDQ will be prolonged and production cost reduced and energy saved.
