摘要： The surface of a roll has built-up weld layers which are arranged in bent waves such that the growth of initial fine cracks which occur on the surface of a roll are prevented. The surface of the built-up weld layer is finished smoothly so that the wavy weld beads prevent the growth of initial fine cracks.

摘要： A method which can readily and accurately detect the depth of cracks in the rolls for transferring hot steel ingot blooms is disclosed. In operation, a fluid of a desired pressure is fed into a plurality of elongated holes formed in the rolls, such elongated holes being disposed in a direction parallel to and along the axis of the rolls and also equidistantly below the round surface of the roll. When cracks occur and reach the elongated holes, the fluid leaks through cracks from the elongated holes and such leakage causes a change in the amount of flow of the fluid. Thereby the cracks can be readily detected by measuring such change of fluid flow by a suitable known detector.

摘要： A method metallurgically bonds a thin film of easily amorphized material on a metallic substrate having a large thermal conductivity, and then irradiates all or selected portions of the thin film with a pulse laser. The irradiated portions become amorphous by rapidly heating and cooling. Therefore, a whole surface which is an amorphous layer or a part of a surface which is an amorphous layer is obtained. In the latter, a porous amorphous metal layer is obtained by subsequent acid elution and by removing the non-amorphous part.

摘要： This invention relates to a heat exchanger structure in which a passage for the cooling or heating fluid is formed. The inner surface of the passage is roughened, and provided with a plurality of lengthwise-extending, inwardly-projecting, linear or spiral, continuous or intermittent fins. The cooling or heating fluid is passed through the passage to promote an increase in the heat exchange rate. In order to manufacture such a heat exchanger structure, a pipe provided on its inner surface with a plurality of lengthwise-extending, inwardly-projecting, continuous or intermittent fins is inserted between a plurality of complementary members to combine these parts in the shape of a mold. The exposed portions of the joint surfaces of these complementary members and such portions of the complementary members and pipe are then hermetically vacuum-sealed. The resultant complementary members and pipe are diffusion-welded unitarily by the hot isotropic pressure welding. A nickel plate or a nickel alloy plate or a stainless steel plate, which is laminated on the portion of the assembled parts which requires to have the wear resisting properties is also diffusion-welded at the same time.
