Abstract (en)
A rectifying system (25) for slab squaring machines which comprises:- a rectifying machine (250) comprising:- a support frame (251);- an electric motor (252) supported by the support frame (251) and provided with a drive shaft (253) rotatable about its own rotation central axis (A), wherein at a free end of the drive shaft an abrasive grindstone (255) is fixed; and- an electric actuator (257) configured to translate the abrasive grindstone (255) along a translation trajectory (D) that is parallel to its central axis (A) with respect to the support frame (251) between a backward position and an advanced position;the rectifying system (25) comprising, in addition,- an abutment body (27) placed along the translation trajectory of the abrasive grindstone (255) at a predetermined distance from the support frame (251) and configured to contact an abrasive surface (2550) of the abrasive grindstone (255) opposite the free end of the drive shaft (253); and- an electronic control unit (30),characterised in thatthe electronic control unit (30) is configured for:- activating the electric activator (257) to translate the abrasive grindstone (255) along the translation trajectory towards the advanced position;- detecting a contact between the abrasive surface (2550) of the abrasive grindstone (250) and the abutment body (27) during the translation run of the abrasive grindstone (255) towards the advanced position, wherein the translation run is imposed to the abrasive grindstone (255) by the electric actuator (257); and- determining a reference position of the abrasive surface (2550) of the abrasive grindstone (255) based on the detected contact.
