The invention relates to a control and/or regulating device for a supporting roll frame (2) of a continuous casting installation (1) for metals, especially steel (3). Said device consists of a plurality of successive roll segments (8), a lower frame (11) and an upper frame (12) which can be adjusted in relation to each other, and paired piston-cylinder units (13). The measuring data of field appliances (14) is detected and processed in a decentralised manner. The aim of the invention is to simplify the field cabling and the regulation design. To this end, functions are displaced onto or close to the roll segments (8) by arranging the field appliances (14) against or on the roll segments (8) or in the vicinity of the roll segment (8) on the fixed stand (17), and the measuring signals thereof are processed and stored by means of axle regulators (18). The field appliances communicate with a memory- programmable control system (19) by means of a field bus module (20).

L'invention concerne un dispositif de commande et/ou de réglage destiné à un train de rouleaux de support (2) d'une installation de coulée continue (1) de métaux, notamment d'acier (3). Ce dispositif comprend plusieurs segments de rouleaux (8) successifs ainsi qu'un cadre inférieur (11) et un cadre supérieur (12) pouvant être mis en contact à l'aide d'unités piston-véron (13) par paires. Les données de mesure d'appareils de champ (14) sont détectées et traitées de manière décentralisée. L'invention vise à simplifier le schéma de câblage et la conception de réglage. A cet effet, on transpose les fonctions à ou à proximité d'un segment de rouleaux (8) en plaçant les appareils de champ (14) contre ou sur les segments de rouleaux (8) ou à proximité du segment de rouleaux (8) de la cage (17) stationnaire, leurs signaux de mesure étant traités et mémorisés par des régulateurs d'axes (18). Et enfin, les appareils de champ communiquent avec une commande par programme enregistré (19) via un module bus de terrain (20).
