Abstract
The invention concerns the continuous casting of metals of all kinds. <??>The invention is characterised in that liquid metal is used as coolant, especially for direct cooling of the strand. The invention further includes a casting device. <IMAGE>
Claims (16)
1) Process for continuous casting of metals, whereby liquid metal or ionic liquid is used as coolant for direct cooling of the strand (4), characterised in that the coolant (8) is forcibly directed at the strand in at least one jet (10) with turbulent flow.
2) Process according to claim 1, characterised in that the coolant (8) is chosen from the group consisting of: lead, tin, bismuth, gallium, indium or alloys of them.
3) Process according to claim 1 or 2, characterised in that the coolant has, in Centigrade Celsius, a melting point which is lower or equal 60% of the melting point of the casting material in Centigrade Celsius.
4) Process according to any of the preceding claims, characterised in that the at least one jet (10) streams into coolant (8) filling the entire gap-like room (11) between the surface of the strand (4) and the inner surface of a pipe (12) which surrounds the strand.
5) Process according to any preceding claim, characterised in that the coolant (8) flows essentially in the direction into which the strand (4) is moving.
6) Process according to any preceding claim, characterised in that the jet (10) has the form of a conical wall jet and in that its Reynolds number amounts to at least 15 000 and preferably to over 25 000.
7) Process according to any of the claims 1 to 5, characterised in that the jet (10) comprises 20 a plurality of individual jets with circular cross section and in that its Reynolds number amounts to at least 5 000.
8) Process according to any preceding claim, characterised in that oxygen or an oxygen containing gas, preferably air, is supplied to the strand upstream of the point where the jet(s) hit(s) the strand.
9) Device for a process according to any of the claims 1 to 8, with a storage tank (16) for the cooling medium, a heating element (17) and a pump (18), with pipes which connect the storage tank (16) with a cooling device (5) for the strand (4) and eventually a heat exchanger (19) which is located in the pipe transporting the coolant from the cooling device (5) to the storage tank (16), characterised in that the cooling device (5) includes at least one nozzle which directs the cooling liquid directly onto the strand, preferably in near vicinity of the mould exit, and a coolant collecting unit (9, 13, 15).
10) Device according to claim 9, characterised in that the cooling device (5) includes a pipe (12) arranged around the strand (4), or its path, respectively, and forming a gap-like room around the strand (4) which is filled with coolant (8).
11) Device according to any of claims 9 or 10, characterised in that at least one coolant distribution unit (6) is provided in near vicinity of the mould exit, combined with a pipe (12) arranged in some distance from the at least one coolant distribution unit (6) in the direction of the movement of the strand (4) and having a second coolant distribution unit (6') on the upstream end of pipe (12).
12) Device according to any of the claims 9 to 11, characterised in that a cleaning unit (7) for the surface of the strand (4) is provided, preferably outside the cooling device (5).
13) Device according to any of the claims 9 to 12, characterised in that the mould (3) is an insulated mould.
14) Device according to any of the claims 9 to 13, characterised in that the nozzle has the form of a ring-like slit surrounding the strand (4).
15) Device according to any of the claims 9 to 13, characterised in that a plurality of nozzles are arranged along a ring-like line surrounding the strand (4).
16) Device according to any of the claims 9 to 14, characterised in that an inlet for oxygen or an oxygen containing gas, preferably air is provided between the mould exit and the nozzle(s) for the coolant.
