BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE DRAWINGS

[0025] The installation according to the invention consists of a mold 1, which consists of a tube body 2 having the same cross-section and a funnel 3 connecting on the top. Plunging into it is a consumable electrode 4, whose axis 5 is arranged obliquely to a vertical 6, which simultaneously forms the axis of tube body 2. Consumable electrode 4 is seated on rollers 7, which form an oblique plane. Consumable electrode 4 is held by a refeeding unit 8, by means of which it can be refed into funnel 3 of mold 1 commensurate to the melt-off.

[0026] The tube body 2 contains the molten material that forms and that solidifies due to the cooling, not depicted here, in the lower region into a billet 10, which is removed downwardly by an apparatus not depicted here and which, if applicable, may be divided into individual blocks by a separating device also not depicted here. These are diverted by a deflection apparatus, which is also not depicted in greater detail, in a lateral direction via means, e.g., a conveyor belt, into a warehouse or storage facility (not depicted).

[0027] Above molten material 9, there is within funnel 3 a slag layer 11 with a horizontally running surface, which is contacted by consumable electrode 4.

[0028] The melting rate level is determined by the size of the consumable surface 13, which is the end surface of consumable electrode 4 contacting slag layer 11. Consumable surface 13 runs horizontally and thus, depending on the inclination of consumable electrode 4, oblique to its axis 5. Since consumable electrode 4 is positioned obliquely, consumable surface 13 increases in relation to cross-sectional area 12 of consumable electrode 4 by an amount that is determined by the size of angle ? between axis 5 of consumable electrode 4 and vertical 6. For an angle of 45?, end surface 13 increases by approx. 40% compared to cross-sectional area 12.

[0029] To allow for an oblique infeed of consumable electrode 4, funnel 3 has an oblique infeed edge 14 on the side of consumable electrode 4.

[0030] The energy for consuming electrode 4 is obtained from a power supply not depicted here. Consumable electrode 4, slag layer 11 as well as molten material 9 and billet 10 form parts of a current circuit, wherein slag layer 11 represents the largest resistance so that most of the energy is absorbed there.
