SINTERING MACHINE FOR EASILY CONTROLLING SINTERING TEMPERATURE

摘要

PURPOSE: A sintering machine for easily controlling sintering temperature is provided to improve sintering productivity by easily controlling temperature according to positions of wind boxes during sintering operation. CONSTITUTION: The sintering machine for easily controlling sintering temperature comprises a drum feeder(120) feeding blended raw materials stored in a blending hopper(110); a sintering car(130) charging the blended raw materials(100) through the drum feeder(120); a heating furnace(140) igniting the surface of raw materials charged onto the upper side of the sintering car(130); wind boxes(200) installed at the lower part of the sintering car(130) to suck in air using a main blower(150); and one or more oxygen ejection means(10) which are installed at the upper part of the sintering car(130) according to certain positions of the wind boxes(200) to eject oxygen onto the surface of the blended raw materials(100), wherein the oxygen ejection means(10) further comprises an oxygen pipe(30) expanded to the inner side of a sealing type hood(20) fixed in a width direction of the sintering car(130); an oxygen nozzle(40) arranged inside the hood(20) so that the oxygen nozzle(40) faces a width direction of the sintering car(130) and the surface of the raw materials(100); and a surge tank(50) to which the oxygen pipe(30) is connected.
