    摘要: A process of manufacturing a roll suitable for use in a rolling mill, the roll having a cylindrical barrel middle section and a neck at each end of the barrel, wherein the barrel and necks are of different material compositions, by remelting an electrode having a central region corresponding in mass and composition of materials to that desired for the barrel of the roll, two end regions corresponding in mass and composition of materials to that desired for the necks of the roll and a transition region disposed between the central region and each end region, each transition region including the material of the barrel and at least one further material. An electroslag remelting process is used in a water cooled mold. The mold is composed of at least two parts and defines a cavity approximating the final outlines of the roll. The mold has tapered transition regions between a part of the cavity corresponding to the barrel and the constricted cavity regions corresponding to the necks. The roll produced in the remelting step is then heat treated and finished.

    摘要: A method of manufacturing high strength and hard metallic composite layer materials by connecting several metal layers with one another, includes forming the metal layers as flat products by rolling from a metal with low base strength, alloying and hardening the flat products over their whole cross-section with a metalloid by heat treatment in a metalloid containing gas atmosphere, then connecting the flat products with one another by diffusion welding. As metalloids preferably nitrogen, boron and carbon are used. Diffusion welding is performed by hot isostatic pressure method.

    摘要: For the low-loss braking of an electrically driven vehicle with two electric motors connected in parallel and arranged one on each side of the vehicle and which are controlled by a pulse control, it is proposed, for one, to brake the vehicle above a prescribed rpm threshold value by useful-current braking, and below it by means of regenerative braking. Secondly, instead of an rpm threshold value, the battery current can also be used as the criterion for one of the two different braking types. A high heat generation in the motors is avoided and energy is saved by this braking process. An electric switching circuit for the conversion of this process is indicated.
