PURPOSE: Provided is an apparatus for measuring stretch of a cokes oven by using a pressure sensor and a hydraulic system, by which the lifetime of the cokes oven can be extended. CONSTITUTION: The apparatus for measuring the stretch of the cokes oven includes: a long tie-rod(2) for measuring the stretch and shrinkage of the cokes oven, which is stretched according to changes of temperature; the pressure sensor(15) for measuring tension which is changed by the stretch of the long tie-rod(2); the hydraulic system(10), in which a stroke is stretched when the long tie-rod(2) is shrunk and the stroke is shrunk when the long tie-rod(2) is stretched; a control part for controlling the hydraulic system(10) by receiving electric signals from the pressure sensor(15). |
