APPARATUS FOR CONTROLLING TEMPERATURE OF SINTER MACHINE TO ALWAYS CONSTANTLY MAINTAIN TEMPERATURE OF WIND BOX BY AUTOMATICALLY CONTROLLING TEMPERATURE OF SINTERING FURNACE

摘要

PURPOSE: To provide an apparatus for controlling temperature of sinter machine to automatically control temperature of sintering furnace by controlling proceeding speed of hearth layer feeding gate and sinter machine according to detection temperature of input side wind box in a process of transferring a blended raw material charged into sintering car to molten sintered ore. CONSTITUTION: In an apparatus for controlling temperature of a sinter machine operated by a motor(45) to manufacture sintered ore by sintering hearth layer fed by a hearth layer feeding damper(22), the apparatus comprises temperature detecting means(111-117) including temperature sensors for detecting temperature at input and output sides of the sinter machine; a deviation operating part(131-135) for calculating a temperature deviation(d) between temperature values at the input side of the sinter machine and temperature values at the output side thereof detected by the temperature detecting means; a temperature control means(140) for providing an error value(f) between the temperature deviation of the deviation operating part and a preset standard deviation(e); first set value operating part(151,152) for converting the error value of the temperature control means into a corresponding damper opening value(g) and adding the damper opening value to a preset damper opening value(h); second set value operating part(161,162) for converting a speed value(j) corresponding to the error value of the temperature control means and adding the speed value to a preset speed value(k); a switching part(170) for a set value(i) of the first set value operating part and a set value of the second set value operating part; a damper track detecting means(241,242) for detecting track of the damper; a damper adjusting means(180) for adjusting an opening ratio of hearth layer feeding gate by comparing a set value of the first set value operating part selected by the switching part with present values detected by the damper track detecting means, thereby adjusting the damper; a speed detecting means(251,252) for detecting speed of the motor of the sinter machine; and a speed control means(190) for controlling speed of the sinter machine motor by comparing the set value of the second set value operating part selected by the switching part with present values detected by the speed detecting means.
