摘要： PROBLEM TO BE SOLVED: To increase the bonding strength of the bonding interface without generating any crack in the bonding interface after inserting, and without cracks in the hard alloy by coating the cast iron of the same composition as that of the bonding material on the surface of the hard alloy. SOLUTION: The hard alloy consists of, by weight, 60-90% tungsten carbide and the balance the bonding alloy. The bonding alloy includes high-chromium cast iron having the composition consisting of 12-32% chromium, 1-3.5% carbon, 1-2% silicon, and the balance iron. The cast iron for the coating includes the cast iron having the composition consisting of, 2-4% carbon, 1-2% silicon, and the balance iron. Because the inserting bonding interface of the coated hard alloy with the cast iron has the same composition, both materials are firmly bonded, and no defective bonded parts are generated. The coating layer becomes the cushioning material, and the hard alloy is not cracked by the thermal shock during the inserting.

摘要： PURPOSE:To enable easy conveyance of slurrylike coarse solid powder, by adding a stabilizer to fluid to be treated. CONSTITUTION:Slurry (suspension) in an agitating tank 13 is fed through a hose 14 to a jet nozzle 10 of a water jet device. Simultaneously, high pressure water is fed through a hose 12 to the nozzle 10, and the slurry is injected at a high speed through the nozzle 10 toward a material 11 to be cut to cut the material 11 to be cut. In this case, a solid and water slurry composition consists mainly of solid powder (fine grain polishing material 21), e.g., aluminum, one or two or more stabilizers selected from a group consisting of alkali metallic salt of caboxymethylcellulose, hydroxyethylecellulose, polyacrylic sodium, and water. As a result, the slurry can be easily conveyed to the nozzle 10 without using a special forced feed device, and spent slurry is returned from a catcher 16 through a concentration control tank 18 to the agitating tank 13 for the reuse.

摘要： PROBLEM TO BE SOLVED: To improve the strength and simplify the manufacturing process by forming a slipper by using a slipper shaping material manufactured by bonding a copper alloy plate to a flat face of an iron material through a bonding material comprising a brazing filler material such as a silver brazing filler and an insert metal composed of Ni, Ni alloy or the like. SOLUTION: A copper allay plate 14 is bonded to a flat face of an iron material 10 by the heating treatment through a bonding material 12 comprising an alloy such as a silver brazing filler, and an insert metal composed of Ni, an alloy of Al and Mn or Ni, an Al alloy and an Mn alloy, to manufacture the slipper shaping material. The slipper shaping material is integrally shaped into a slipper by a forging process and a cutting process in a state that the copper alloy plate 14 side is used as a sliding face 20 with a plate in order to obtain a desired slipper 18a. Whereby the slipper 18a can be provided with the sufficient strength, and the slipper can be easily manufactured because the thickness of the iron material 10 is not limited as is different from a case of the sintering rolling.

摘要： PURPOSE:To lessen residual stress of both an inner tube and an outer tube by interposing joining material such as solder material or the like between the inner tube and the outer tube at the time of relatively superimposing the inner tube and the outer tube to increase the diameter of the inner tube or reduce the diameter of the outer tube so that the inner tube and the outer tube are united in a body. CONSTITUTION:Solder material 2, 2 as paste joining material is applied to the inside face of an outer tube 1 in designated lines along the longitudinal direction, and in such a condition, a stainless inner tube 3 is relatively superimposed on the outer tube 1 through a ring-shaped space 4 as narrow as possible. Secondly, by a thermal tube expanding method, designated liquid pressure F is applied to the interior of the inner tube 3 to increase the diameter of the inner tube 3, so that the inner tube is united in a body with the outer tube 1. Subsequently, with the solder material 2' spread throughout, heaters 5 are installed like a ring to heat and melt the solder material 2', so that the solder material is spread between the inner tube 3 and the outer tube 1 throughout.

摘要： PROBLEM TO BE SOLVED: To devise the structure of a heat resistant metal cylinder made furnace core tube upon a furnace core tube of an external heating rotary kiln being made into a single heat resistant metal cylinder such that wear resistance and heat resistance of an internal surface of the furnace core tube, and chemical and physical stability are improved. SOLUTION: For a furnace core tube of an external heating rotary kiln it is made of a heat resistant metal cylinder, and ceramics powder is sprayed onto the internal surface of the heat resistant metal cylinder to form a 100 μm to 1000 μm thick ceramics spray coated film. Since the internal surface of the heat resistant metal cylinder is coated with the ceramics spray coated film, a workpiece is prevented from making direct contact with the surface of the heat resistant metal cylinder. Further, since the ceramics spray coated film layer on the internal surface of the heat resistant metal cylinder is excellent in wear resistance, heat resistance, and chemical and physical stabilities at high temperature, contamination is produced from the surfaces of the spray coated film and the heat resistant metal cylinder, which is in turn prevented from being mixed into the workpiece. Further, since the thickness of the ceramics spray coated film is less than 1000 μm, heat transfer property of the furnace core tube due to the heat resistant metal cylinder is not obscured, heat efficiency is high with excellent temperature control property and hence quality control of the workpiece is facilitated.
