摘要： A mixed powder layer is applied by coating to a cavity of a forging die made of an Fe-base alloy, at least to the region of the cavity to be reinforced or repaired, the mixed powder layer comprising the first element powder capable of being converted into a carbide to enhance the hardness of the forging die and the second element powder having a melting point lower than that of the first element powder. Die reinforcing is carried out by forging a work by using a forging die covered with the mixed powder layer and heat-treating the die by utilizing the working heat generated in the forging to thereby make the layer reflow and diffuse the carbide in the die.

摘要： A machine tool or die that is fabricated from thermally spray-formed steel is easily repaired by cleaning, roughing and covering the surface to be repaired by a cold-spray layer of metal and then forming a weldment by conventional electric welding processes. The repaired surface is then finished by conventional machining, grinding and polishing and then the tool is put back into service.

摘要： Bosses project from the outer surface of the ingot mold and are arranged in a planar zone, each of the bosses contains a channel that has slidably positioned therein an anchor which is projected beyond the outer surface of each boss into each boss. The projecting portions of the anchors are attached to a continuous reinforcement band extending between the projecting portions of the anchors. The continuous reinforcement band is spaced from the ingot mold. Stresses and strains caused by teeming (pouring) hot molten metal into the ingot mold are absorbed by the continuous reinforcement band.

摘要： A method for making or repairing lugs and trunnion members for ingot molds by forming a casting space or cavity corresponding to the shape of the lug or trunnion member on the side of the ingot mold where the member is to be secured, forming a casting material feeding chamber above the casting cavity, introducing a predetermined amount of an alumino thermic mixture to the welding chamber and reacting said alumino thermic mixture whereby the molten metal produced from such reaction feeds into and fills the casting cavity and upon cooling forms the desired lug or trunnion. The apparatus for carrying out the process comprising a welding chamber composed of a lower casting space or cavity and an upper casting material feeding chamber is also disclosed.
