1. A device for continuous casting of steel, comprising:a mold having mold walls ( 1 , 18 ) at least one of which includes a mold steel wall ( 2 ) and a support mesh ( 3 ) for the mold steel wall ( 2 );a magnetic field generator ( 3 . 2 ) for generating a magnetic field ( 3 . 1 ) which acts on the mold steel wall ( 2 ) via the support mesh so that the mold steel wall ( 2 ) is attracted to the support mesh ( 3 ); anda mold cooling device including spray cooling means ( 10 ). 2. A device according to claim 1, wherein the mold steel wall ( 2 ) has a thickness between 0.5 and 5 mm. 3. A device according to claim 1, wherein the mold steel wall ( 2 . 1 ) consists of a steel layer and a copper layer. 4. A device according to claim 1, wherein the mold steel wall ( 2 . 1 ) consists of metal/steel/metal layers. 5. A device according to claim 4, wherein the metal layers are copper layers. 6. A device according to claim 1, wherein the support mesh ( 3 ) includes a support wall ( 11 ) with chambers ( 9 ) formed therein, and wherein the magnetic field ( 3 . 1 ) is transmitted into the mold steel wall via the support wall ( 11 ). 7. A device according to claim 6, wherein the spray cooling means ( 10 ) includes spray nozzles ( 10 . 1 ) extending into the chambers ( 9 ) of the support mesh ( 3 ) for cooling the mold steel wall ( 2 ) from the rear. 8. A device according to claim 1, wherein the mold has a mold inlet ( 6 ) and a mold outlet ( 7 ), and the mold steel wall ( 2 ) is secured horizontally at the mold inlet ( 6 ) or the mold outlet ( 7 ). 9. A device according to claim 1, wherein the support mesh ( 3 ) has a support wall ( 11 ) provided, at its ends adjacent to the mold steel wall ( 2 ), with balls ( 11 . 2 ) which support the mold steel wall ( 2 ) for thermally induced movement. 10. A device according to claim 9, wherein the balls ( 11 . 2 ) are filled with a fluid medium. 11. A device according to claim 1, wherein the support mesh ( 3 ) has a support wall ( 11 ) having at its ends facing the mold steel wall ( 2 ), a graphite ( 11 . 1 . 1 ) rounded support mesh head. 12. A device according to claim 1, wherein the support mesh ( 3 ) includes an outer frame surrounding the support mesh, and the outer frame has a sealing ( 3 . 3 ) for controlling return flow of mold spray cooling medium ( 10 . 2 ). 13. A device according to claim 1, further comprising a collection chamber ( 12 ) and a drain ( 12 . 1 ) for a directed removal of cooling medium ( 10 . 2 ) sprayed onto the mold steel wall ( 2 ), and wherein the cooling medium ( 10 . 2 ) that flows back over a support wall ( 11 ) of the support mesh ( 3 ), is collected in the collection chamber ( 12 ) and is removed one of through the drain ( 12 . 1 ) and into open atmosphere. 14. A device according to claim 1, wherein narrow sides ( 18 ) of mold forming walls include a steel wall having an inner convexity ( 18 . 1 ) for a mechanical stabilization. 15. A device according to claim 1, wherein narrow sides of mold forming walls are formed of copper plates. 16. A device according to claim 6, wherein the spray nozzles ( 10 . 1 ) of the mold spray cooling means and feed conduits for the cooling medium ( 11 . 3 ) are integrated one of partially and completely in support walls ( 11 ) of the support mesh ( 3 ). 17. A device according to claim 6, wherein the chambers ( 9 ) of the support mesh ( 3 ) have a honeycomb shape. 18. A device according to claim 1, wherein the magnetic field generator ( 3 . 2 ) is formed as a permanent magnet ( 3 . 4 ).
