摘要： PROBLEM TO BE SOLVED: To economically enhance the abrasion resistance of the surface of the side plate of a rotor used in a vertical rotary centrifugal lump crushing apparatus. SOLUTION: When an abrasion-resistant metal is applied to the surface of the side plate 12 of the rotor 10 by weld padding, a placing material 20 the abrasion resistance of which is more excellent than that of a welding wire 30 is placed on the surface of the side plate 12 and weld padding is applied to the surface of the side plate 12 from the upside of the placing material 20. The placing material 20 is melted and the build-up hardened metal is thickened by the chemical components of the placing material to be enhanced in its abrasion resistance.

摘要： PROBLEM TO BE SOLVED: To prevent abnormal wear of an inner face in the vicinity of a connection part of a straight pipe connected with an outlet side and to enable the application to high temperature environment and a field of food. SOLUTION: A wear-resistant hard metallic layer 20 is formed by build up welding on at least an outer face of an outer peripheral side of a curved part of a base material bend pipe 10 using a weldable metal as a raw material and having a wall thickness of 15.1 mm or less. A holding layer 30 is formed by build up welding austenitic stainless steel or austenitic manganese steel containing chromium and nickel from a surface of the wear-resistant hardened metallic layer 20 to a surface of the base material bend pipe 10. The wear- resistant hardened metallic layer 20 melts into the vicinity of an inner face of the base material bend pipe 10 to suppress abrupt wear of the inner face. The holding layer 30 has excellent heat resistance and holds the wear-resistant hardened metallic layer 20 in the base material bend pipe 20 under high temperature environment to prevent leakage through a crack occurring in the hard metallic layer.

摘要： PROBLEM TO BE SOLVED: To prevent the wear of the inner face of a straight pipe near its connection to the exit side of a wear-resistant bend pipe. SOLUTION: A wear-resistant hardening metal layer 20 is formed on, at least, the outer face on the outer periphery side of a curved portion of a base material bend pipe 10 using a weldable metal as a raw material with buildup welding. The periphery of the base material bend pipe 10 is coated with a reinforcing plastic 30 so as to cover the wear-resistant hardening metal layer 20. The thickness of the base material bend pipe 10 is 9 mm or less. The wear- resistant hardening metal layer 20 is welded in proximity to the inner face of the base material bend pipe 10 to restrain the quick wear of the inner face thereof.

摘要： PROBLEM TO BE SOLVED: To provide a both-face clad steel sheet that can be made thin enough in thickness though it has wear-resistant, hardened metal layers on its both faces, and also can be formed into a bent sheet with a small radius. SOLUTION: A punched steel sheet 31 having a plurality of through holes 32 is joined by welding to one or both faces of a base steel sheet 10. A wear- resistant metal is deposited by welding in each through hole 32 of the punched steel sheet 31 to form a plurality of deposited portions 34 on the surface of the base steel sheet 10. Making rib portion 33 of the punched steel sheet 31 melt to bridge the plurality of deposited portions 34 results in a wear-resistant, hardened metal layer 30 on the surface of the base steel sheet 10.
