    摘要: A method of continuous rolling comprises the steps of: forming a continuous billet 20 by joining a rear end of preceding billet 21 with a front end of succeeding billet 21 by flash-butt welding 3; removing burr on welded portions of the continuous billets 20; then rolling the continuous billet 20 in a rolling mill line 6; wherein locally cold portions produced by clamping at welding are reheated after removing the burr using a travelling induction-heating unit 5 running at a speed synchronously with a running speed of the continuous billet 20, which travelling induction-heating unit 5 is provided with induction-heating coils arranged at the same distance with that of the locally cold portions.

    摘要: There is disclosed a method by which a channel-type induction heating apparatus is provided on a tundish, which comprises a steel receiving chamber and a steel discharging chamber separated by a refractory wall, each of which chambers is connected to the ground via molten steel flowing from a ladle, molten steel flowing into a mold, or a refractory, in such a manner that ground circulating current is prevented from being generated. An electromagnetic connection of an induction heating coil and an iron core of a two-leg type or a three-leg type to a loop current circuit in the molten steel is arranged symmetrically, thereby suppressing the generation of the ground circulating current. By thus suppressing the generation of the ground circulating current, it becomes unnecessary to insulate a ground circuit as required in conventional constructions, the maintenance of facilities becomes easier, besides any malfunction of the equipment due to the ground circulating current is totally eliminated.

    摘要: Evaporator crucible for vacuum depositing systems, having a crucible bottom with at least one bottom opening for the introduction of material in rod form for evaporation. At a distance from the bottom opening there is provided at least one metal crucible rim which preferably is provided with a coolant passage. To solve the problem of reducing the heat losses, the crucible rim is provided internally on at least a part of its depth with a lagging comprising ceramic material. This lagging preferably comprises individual ceramic building blocks which are preferably compressed from magnesium oxide.
