An ingot has been produced by continous casting and cutting a length of the casting. The ingot is presumed to be used for being rolled into a product having particular profile and to be obtained by rolling different portions of the ingot differently as far as reduction in local thickness is concerned. The end faces of the ingot are provided with arch-shaped recesses in those regions of the ingot, which will undergo a higher degree in reduction than the remainder, so that the ingot in turn can have dimensions more suitable for continuous casting, while such dimensions do not have detrimental effect on rolling due to the recesses. |
