SINTERING METHOD FOR IMPROVING DEGREE OF RECOVERY

PURPOSE: A sintering method for improving a degree of recovery is provided to improve a degree of recovery, efficiency of a dust collect, and heat efficiency in a bed of a sinter machine by calcining the adsorbed material together with hearth layer ore after adsorbing fine particles being lost and raw materials by humidifying and preheating hearth layer ore when the hearth layer ore is loaded into a sinter machine. CONSTITUTION: A sintering method for improving a degree of recovery consists a first process (100-103) in which a main gate is opened by pressing a start button, and then a steam amount injected based on a speed of a sinter machine and a hearth layer ore thickness, and a discharged amount of a hearth layer ore are calculated, a second process in which a sinter machine is operated (106) after opening (104) a control valve of steam flow rate based on the calculated value in the first process, and opening (105) a discharged amount gate of hearth layer ore, a third process in which an opening condition of a steam injection valve is adjusted (107-111) by comparing a steam injection amount with a set value, and simultaneously an opening condition of gate position is adjusted (107a-111a) by comparing a charged amount of hearth layer ore with a set value, and a fourth process (112-114) in which a sinter machine is returned to an initial condition when the sinter machine is not in a stop condition, and a steam valve and a gate valve are closed when the sinter machine is in a stop condition by judging whether or not the sinter machine is in a stop condition.
