Abstract

Procédé de production d'une bande d'acier à chaud, selon lequel on réalise un laminage de dégrossissage d'une brame d'acier chauffé à la température de laminage afin d'obtenir une bande d'acier, et on effectue ensuite de façon continue un laminage de finissage à chaud de cette bande d'acier, ce procède étant caracterisé en ce que l'on amène à recouvrement, pendant ou avant le laminage de finissage à chaud, l'extrémité menante d'une bande d'acier en cours de laminage par le laminoir de dégrossissage à chaud, sur l'extrémité terminale d'une bande d'acier laminée antérieurement de la même façon, en introduisant, entre les parties en recouvrement desdites extrémités de ces deux bandes, un agent de fusion des écailles d'oxyde, qui réagit avec ces écailles d'oxydes présentes sur les surfaces opposées des parties en recouvrement, sous l'action de la chaleur de ces parties en recouvrement, et qui forme une substance à bas point de fusion, en ce que l'on relie par réduction les parties en recouvrement, et en ce que l'on soumet de façon continue les bandes d'acier ainsi reliées au laminage de finissage à chaud.A method of producing a hot steel strip, wherein rough rolling of a steel slab heated to the rolling temperature is carried out to obtain a steel strip, and then carried out in such a manner. continues a hot finishing rolling of this steel strip, this process being characterized in that during or before the hot finishing rolling, the leading end of a steel strip is overlapped. during rolling by the hot roughing rolling mill, on the terminal end of a steel strip previously rolled in the same way, by introducing, between the overlapping parts of said ends of these two strips, a melting agent of the oxide scales, which react with these oxide scales present on the opposite surfaces of the overlapping parts, under the action of the heat of these overlapping parts, and which forms a substance with a low melting point, in that we connect by reduction the recou vrement, and in that the steel strips thus connected are subjected continuously to the hot finishing rolling.
