METHOD OF THERMO-MECHANICAL TREATMENT OF HOT-ROLLED ROUGH STRIP PRODUCED ON LINE OF THIN SLAB CONTINUOUS CASTING, AND SYSTEM TO COIL AND UNCOIL STRIP

摘要

A system and the relevant thermo-electromechanical process with two superimposed devices (A) able to coil and uncoil a pre-strip (a) by reversing their positions, provided with outer (4) and inner (7) burners to respectively equalize and optimize the temperature along the whole pre-strip by means of special algorithms of the control software, suited to also control the speed, acceleration and deceleration, both in the coiling and uncoiling step, of the chuck (6) up to the advanced stop during coiling to let a segment of tail (c) of the pre-strip out of the device (A). A particular structure of the chuck (6) is also described.
