Abstract
Process for secondary cooling of a metal product continuously cast on a machine in which secondary cooling is divided into n staggered independent zones, within which the flow of cooling fluid varies according to the speed of the product. An undesired change in the surface temperature of the product at a point HD of the metallurgical length of the machine, such as the straightening point, due to a foreseen or foreseeable variation starting at the time t.sub.vo, in the casting speed, is compensated for by anticipation. A determination is made, by means of the casting speed, of the time t.sub.o at which commences, at the upper part of the ingot mold, the portion of product which, at the time tvo, will reach the point HD; a further determination is made of the times t.sub.1, . . . , t.sub.1, . . . , t.sub.n at which the portion commencing at t.sub.o will emerge from the zones 1, . . . . i. . . . ,n of the secondary cooling; and, from the time t.sub.vo, the method of cooling conventionally used is recommenced, varying according to the actual speed.
