An apparatus for guiding rolled material having warp or bending part in hot rolling line

An apparatus for guiding a rolled material having a warped or bent part in a hot rolling line is provided to improve threadability and rolling quality of the rolled material by preventing the generation of facility damage or process delay due to the collision between the front end of the rolled material and transfer rolls although a front end of a slab or plate as a rolled material is warped or bent. An apparatus(1) for guiding a rolled material having a warped or bent part in a hot rolling line comprises: at least one material guiding roll(50) which is installed between transfer rolls(12) for threading the rolled material at one side of rolling rolls(10) such that height of the material guiding roll varies, and which is disposed to avoid a contact between a front end(32) of a rolled material(30) having a warped or bent part and the transfer rolls; and a guiding roll supporting and driving means(70) including a roll support(74) which is pivoted to a fixing member(72) disposed between the transfer rolls, and which has the material guiding roll connected with an upper portion thereof such that the material guiding roll is idled, and a drive source(78) connected to one side of a moving bar(76) horizontally connected to a lower part of the roll support, the guiding roll supporting and driving means varying the height of the material guiding roll by rotational motion of the roll support.
