    Abstract: A method of continuously casting a molten ferrous alloy in a casting means to obtain a solidifed cast bar at a hot-forming temperature, passing the cast bar at a hot-forming temperature from the casting means to a hot forming means, and hot forming the cast bar into a wrought product by a two-stage reduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a substantially uniform fine grained, equiaxed or cell structure in the outer surface layers of the cast bar by a selected small amount of deformation of the cast bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area forms the wrought product. The substantially uniform subgrain structure formed on the cast bar during the first stage of deformation produces a bar that has increased ductility compared to bar produced by the prior art processes and permits substantial reduction of the cross-sectional area of the cast bar during the second stage of deformation without the cast bar cracking, even when the cat bar has a relatively high precentage of alloying elements present.

    Abstract: A method of continuously casting a molten metal in a casting means to obtain a solidified cast bar at a hot-forming temperature, passing the cast metal at a hot-forming temperature from the casting means to a hot-forming means, and hot forming the cast bar into a wrought product by a two-stage reduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a shell of finely distributed recrystallized grains in the surface layers of the cast bar by a selected small amount of deformation of the cast bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area forms the wrought product. The shell of fine grains formed on the cast bar during the first stage of deformation permits substantial reduction of the cross-sectional area of the cast bar during the second stage of deformation without the cast bar cracking, even when the cast bar has a high impurity content.

    Abstract: A rod or bar mill stand has two work-roll carrying mountings which are pivoted together on one side of the plane containing the roll axes and which are individually connected to synchronously driven eccentrices. The eccentric drives for the roll mountings, together with the pivotal connection, cause each of the roll axes to follow an eliptical or oval path, such that each roll approaches the pass line to reduce the work, over a part only of the path. The work rolls are driven about their own axes to induce forward movement of the work.

    Abstract: A material 1 to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material 1, close to the transfer line from above and below the material 1, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material 1, are transferred from the upstream to the downstream side in the direction of the transfer line.
