    摘要: There is disclosed a method and arrangement for inspecting the surface of steel stock having a temperature above the Curie point. In order to detect, with a great certainty and accuracy, defects in the hot steel stock, with a loss of energy for cooling the steel stock for inspection and subsequently reheating it for further processing being avoided, only a thin surface layer of the steel stock is intensively cooled on the surface to be inspected, to a temperature below the Curie point. The core of the steel remains hot. Immediately thereafter, a magnetic or electromagnetic field is induced in the cooled surface layer and disturbances in the induced field caused by defects in the steel stock are detected and recorded by pick-ups.

    摘要: At least two magnetic induction elements operated with alternating current are disposed successively in the longitudinal direction at the guide for a strand of a continuous casting plant, and in particular for a continuous steel casting plant, to provide a stirring mechanism. Each induction element is connected to its own phase (R, S, T, N) of the at least two phase alternating current and the phases (R, S, T, N) are shifted with respect to each other by a phase angle of from about 0 to 180 degrees. In order to avoid the formation of a continously uniformly directed circulating current of metal despite a simple and sturdy stirring provision and without the presence of additional switching circuits, the phases (R,S,T) generate in each case electromagnetic forces under formation of a magnetic alternating field at at least two neighboring induction elements, where the momentary value differences and the directional differences correspond to a phase shift of .PHI.+180 degrees.

    摘要: A method of establishing a turbulent motion of molten steel within a strand guide of a continuous casting plant for casting a steel strand, wherein at least one group of three electromagnetic induction coils are arranged adjacent the strand guide, two of the induction elements being arranged consecutively in the longitudinal direction of the guide. At least two of the induction elements are offset relative to each other, transverse to the longitudinal direction of the strand guide, and the three induction elements form the corner points of an imaginary triangle having no more than one side lying in a plane extending parallel or perpendicular to the longitudinal direction of the strand guide. The imaginary triangle extends across the width of the strand. One phase of a three phase AC current is connected to each electromagnetic induction element. One of the induction elements has its input terminals electrically reversed with respect to the other two elements. When power is applied to the induction elements, a discontinuous electromagnetic AC field is established within the imaginary triangle extending across the width of the strand, wherein the electromotive forces produced by the induction elements produce travelling waves in several directions to cause a turbulent motion and an effective mingling of the melt within the strand over the total width of its liquid core.
