DEVICE FOR DETECTING SMOOTHNESS OF HOT-ROLLED SHEET BETWEEN ROLLING STANDS

摘要

PURPOSE: A device for detecting the smoothness of a hot-rolled sheet between rolling stands is provided to protect a load sensor from such exterior factors as instantaneous shock load and high temperature, to extend the life span of a smoothness detecting device by adjusting heights between rolls and to prevent a distortion of a smoothness detecting signal. CONSTITUTION: In a contact type smoothness detecting device, a smoothness is detected by sensing load via multiple rolls(30) divided widthwise of a hot-rolled sheet(S) produced in a hot finishing mill process. The rolls are separably combined to a support housing. A normal directional height adjusting device(32) moving the rolls in a normal direction and a tangent directional height adjusting device(33) moving the rolls in a tangent direction are installed in a portion of a support(31) supporting the rolls. A shock absorber(39) is installed on a plate(34) movably combined to the end of the tangent directional height adjusting device. A pressurizing member(36) pressurizing a load sensor(35) is compressed previously. A pre-load applying device(37) is installed on the plate for preventing the load sensor from being displaced. A housing(38) is installed between the load sensor and the plate for preventing the load sensor from overheating.
