The invention relates to an apparatus for rolling a metallic product comprising a mill frame (), a first cantilever roll shaft (), a second cantilever roll shaft (), both said roll shafts () being mounted on the mill frame () with two sets of bearing assemblies (), a first rolling ring () mounted on the first roll shaft (), a second rolling ring () mounted on the second roll shaft () said rolling rings () forming a nip () in between, at least one ring () arranged with its inside surface () in rolling contact with the first roll shaft () and with at least one intermediate roll (), which intermediate roll () is arranged also in rolling contact with the second roll shaft () and at least one drive end () arranged at the end of either roll shafts () for driving the mill (). The invention also relates to a method of producing a metallic product.

The invention is relating to a system for casting metal, the system comprising a holding furnace () containing a base metal melt (), at least one casting crucible () mounted inside the holding furnace () and situated at least partly in the base metal melt (), the said casting crucible () divided to at least first volume () and second volume () with a separating wall (), which separating wall () is forming a gap () with the casting crucible wall () said casting crucible () having at least one opening () in the wall () from the first volume () to the base metal melt () in holding furnace () and having means to import alloying material () to the first volume () and having at least one casting die () in the second volume () inserted into the alloyed metal melt (). The invention also relates to a method of casting metal.

Method and system for casting metal and metal alloys

The invention relates to a method for producing a metal strip from a cast by rolling in which method the technique of a profiled rolling in combination with a strip rolling is used. The material for the metal strip is first cast by using a casting technique to produce a cast profile having the center part thicker than the lateral parts and the cast profile is in an essentially continuous manner conducted into a rolling mill where during the at least two-staged profiled rolling the cast profile is divided into two symmetrical segments and maintained as two equal segments. These segments are spread into the lateral regions of the material to be rolled into a flattened profile which is as an object for at least one-staged strip rolling so that the spread ratios between the center part dimension of the cast profile and the width of the strip of greater than 2.8:1 are achieved.

Method for producing a metal strip

The invention relates to a method for rolling a metal profile into a metal strip in which method the technique of a profiled rolling in combination with a strip rolling is used, comprising that during the at least two-staged profiled rolling the metal rod is divided into two symmetrical segments. These segments are spread into the lateral regions of the material to be rolled into a flattened profile which is as an object for at least one-staged strip rolling so that the spread ratios between the diameter of the rod and the width of the strip of greater than 2,8:1 are achieved.

Method for rolling metal material into a metal strip

The invention relates to a coil to be used in transverse flux induction heating of an object in the form of a metal strip or another elongate metal workpiece. The coil contains at least one pair of loops of conductors, which are non-symmetrically positioned to each other and the conductors overlap each other so that the inductor has double conductors across the object to be heated and a single conductor parallel to the object to be heated at the edges. The heating effect is prevented alone in the conductors by dividing the induced current for the conductors to two equal branches each having the same width as the original current and the combined heating effect in the branches is only half of the heating effect before branching.
