摘要： PROBLEM TO BE SOLVED: To make a portion embedded in a base material made of a wear resistance material difficult to be cracked.SOLUTION: When manufacturing a wear resistance composite material in which a wear resistance material 2 having higher wear resistance than a metal of a base material 3 is joined with the base material 3, the wear resistance material 2 is so constituted as to include a base material embedded part 2a having relatively high toughness and a mold embedded part 2b having relatively low toughness. The mold embedded part 2b is embedded in a mold 1, and the base material embedded part 2a is projected from the inside of the mold 1. Then, the molten metal of the base material 3 is supplied into the mold 1, and the base material 3 is solidified and it is released from the mold 1. Thus, the base material embedded part 2a is embedded in the base material 3, and the mold embedded part 2b is projected from the surface of the base material 3. In such a condition, the wear resistance material 2 and base material 3 are entirely joined together with a mold.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing pipe joints of an iron based shape- memory alloy having substantially uniform columnar crystal rate i.e., shape- memory function over the whole length by a centrifugal casting method.
SOLUTION: The columnar crystal rate exceeds at least 70% of the wall thickness over the whole length of a pipe in any transverse cross section, by beginning casting of molten steel with predetermined composition from the casting point arranged at the one end of the mold rotating at high speed, continuing the casting while moving the casting point to the other end at constant speed in a direction of rotating axis of the mold, and spraying exothermic- insulating flux on the surface of the cast molten steel and moving it to the other end of the mold. Further, it is most desirable to use Ca-Si based flux as the exothermic-insulating flux.

摘要： PROBLEM TO BE SOLVED: To provide a high-temperature wear-resistant material which exerts excellent wear and cracking resistances in high-temperature environments and is inexpensive.SOLUTION: A high-temperature wear-resistant material contains 0.2-0.5 wt.% of C, 0.2-1.5 wt.% of Si, 10-24 wt.% of Mn, 12-20 wt.% of Cr, less than 4.0 wt.% of Ni, less than 0.1 wt.% of N and remaining Fe and unavoidable impurities. An inspection of N for a finished product can be omitted owing to no addition of N during casting, leading to an inexpensive high-temperature wear-resistant material. Limiting contents of other alloy elements in a specified range, together with no addition of N during casting, allows the high-temperature wear-resistant material to exert wear resistance and cracking resistance comparable with those attained by conventional materials in a specified high-temperature environment.

摘要： PROBLEM TO BE SOLVED: To provide high chromium cast iron whose wear resistance can be improved.SOLUTION: The high chromium cast iron includes Mn of 2.15 to 3.5 wt.%. The high chromium cast iron is charged to a hearth rise and fall type high temperature furnace; its temperature is raised from room temperature to 1,000°C at a temperature rising rate of 100°C/h, and it is thereafter heat-treated for 3.2 hr at 1,000°C. Then, the high chromium cast iron is cooled from 1,000 to 300°C for t min, is subsequently subjected to natural cooling to ≤100°C in the hearth rise and fall type high temperature furnace, and is discharged from the hearth rise and fall type high temperature furnace. In this way, quenching of the high chromium cast iron is completed. As a result, hardness of the high chromium cast iron reaches ≥61 HRC at respective parts in which the cooling times t are different, which are 207 min, 414 min and 828 min. This 61HRC is the minimum value capable of preventing accelerated progress of wear.

摘要： PROBLEM TO BE SOLVED: To inexpensively prolong the service life of a sintering cake support stand disposed on a sintering pallet of a sintering machine. SOLUTION: A top 3a of a stand body 3 is protruded from a plane including the surface of a central part 3b and a plane including the back face so as to have a thick wall, and thick-walled parts 5a, 5b protruded from the plane including the surface of the central part 3b and the plane including the back face are provided along side edges of lateral parts 3c slantly downwardly expanded from both side edges of the top 3a. By reducing pressure applied from a sintering cake to the top 3a and both lateral parts 3c to suppress the progress of wear, the service life of the stand can be elongated inexpensively. Compared to a thick-walled part 5a arranged at the row end side of a stand row, an area of the thick-walled part 5b at the other side preventing wear is reduced. Thus, this can suppress an increase in material coat and weight caused by wall thickening. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high temperature corrosion resistant member and a heat exchanger which have a small risk of occurrence of abnormal corrosion even when, in an atmosphere where ash containing alkali sulfates (NaSO, KSO) is present, exposed to a high temperature equal to or higher than the eutectic point (832°C) of the alkali sulfates.SOLUTION: A high temperature corrosion resistant member is exposed to a temperature equal to or higher than 832°C.
