The invention relates to metallurgy and can be used for production of the blooms and slabs from the castings produced in the moulds, especially in the extended toward the bottom. Steel (liquid metal) teeming is carried out into casting molds, in which in the ground part a figure is made, which consists of faces of an inverted truncated pyramid or a cone or a paraboloid, or a figure composed from elements thereof. The casting mold can be both closed-bottom and through with a bottom plate, in which a deepening is made in the form of said figure. After solidification of metal in the casting molds extraction of the castings from the moulds (stripping) is performed. Then the castings are heated in wells and transferred to a blooming mill, where after several passes with relative degree of deformation in each of them ε = 0.06÷0.30 a slab or a bloom is produced. In the bottom part a breakdown bar after rolling has insignificant final fins (up to 1.5%), or they are absent at all. Due to the form of bottom part and mode of reductions it is possible to decrease the bottom discard up to 0.4÷1.5 % irrespective of the direction of rolling casting, namely by bottom or principal part in forward direction. In the case due to the form of deepening the high durability of bottom plate is ensured.
