PROCEDIMIENTO Y DISPOSITIVO PARA EVITAR Y CONTROLAR UNA DE- FORMACION CRITICA DE LA CASCARA DE BARRAS DE ACERO.

摘要

A method and apparatus are disclosed for monitoring and obviating deformation of the shell of continuous castings. Reference pick ups are used to measure from a reference line the bulging of the casting shell between adjacent guiding rollers and to measure the instantaneous distance of the guide rollers from the reference line. The differential between these measurements is determined and in accordance therewith the casting travel speel and/or quantity of coolant is regulated to avoid undesired bulging.
