PURPOSE: A tie rod tension control device and a pressure control method of a coke oven are provided to automatically control the tension of a tie rod with improved work accuracy. CONSTITUTION: A tie rod tension control device of a coke oven comprises a pressure detector(30), a fixing nut(20), a driving unit(40), and a control unit(50). The pressure detector is fitted to a tie rod and elastically pressed between the fixing nut and a pinion wall to detect pressure according to the contraction and expansion of the coke oven. The fixing nut is coupled to the leading end of the tie rod and fastens or unfastens the tie rod to control the pressure of the coke oven. The driving unit is connected to the fixing nut in order to rotate the fixing nut. The control unit computes the signal of the pressure detector and controls the driving unit. |
