Abstract: The present invention refers to a cooling control system of a coiling mandrel (102; 202; 302; 402; 502; 602) for metal products which comprises: an internal shaft (108; 308) with a plurality of sectors (109); an external drum which as a whole contains coaxially said internal shaft and which is circumferentially subdivided into a plurality of segments (104) arranged in a direct or indirect coupling connection with said sectors; and an internal and/or external cooling system of the mandrel The segments are movable in a radial direction with respect to said internal shaft through an axial movement of the latter, causing the consequent radial expansion or collapse of the drum. The mandrel is further provided with a group of temperature detection sensors (130, 132, 134, 136; 234, 236; 332, 336; 43N; 53N; 63N; 3N). A method for monitoring and adjusting the temperature of a coiling mandrel is also described.

Abstract: Apparatus to guide a metal product, the apparatus includes a support body (11). A plurality of support arms (12) are associated with the support body (11). A plurality of guide rolls (13) are installed rotating in an idle manner on the support arms (12) and define between them a roller guide gap (14) for the metal product. Adjustment devices (24) associated with the support arms (12) and adjust, independently from each other, the position of each of the guide rolls (13. Detection devices (19) detect the stresses induced by the metal product on the guide rolls (13).
