ABSTRACT OF THE DISCLOSURE A hot top consists of a number of sheets of insulating fibrous material. The principally vertical walls of the hot top consist of a number of sheets located close to and joined to one another. When the hot top is placed in an ingot mould, these sheets cover the upper part of the ingot mould walls. The hot top has an upper confinement consisting of one or more sheets of insulating fibrous material which cover the opening formed by the vertical sheets. One or more - containers holding additives used in casting are arranged in the space under the confinement. In one preferred embodiment-, the walls of the hot top, the upper confinement of the hot top and the hot top containers holding additives form a single unit matched to the dimensions of the ingot mould, so that in a preferred embodiment, the unit is assembled before the hot top is inserted into the ingot mould.
