摘要： PURPOSE:To secure a compound oxide superconductor having a good supercon ductor characteristic by cooling molten metal or rare earth metal and copper or this rare earth metal and copper plus an alkaline earth metal alloy quickly for solidification, forming a thin strap or a wire rod, and then performing heat treatment at a temperature of less than a specified melting point under a high- pressure gas atmosphere of specified oxygen partial pressure. CONSTITUTION:Molten metal of rare earth metal and copper or this rare earth metal and copper plus an alkaline earth metal alloy is quickly cooled and solidi fied, thereby forming a thin strap or a wire rod. Then, oxidation takes place after heat treatment under a high-pressure gas atmosphere of more than 1.5kgf/ cm in oxygen partial pressure at temperature of less than a melting point (above 300 deg.C), whereby a compound oxide superconductor consisting in a good superconductor characteristic is secured, and a superconductive magnet available for magnetic levitation and a fusion reactor or the like is manufactured.

摘要： PURPOSE:To perform efficient and automatic quick spheroidizing heat treatment of plural steel bars having a large diameter and a specified length by performing all the operations for feeding successively the steel bars from a feed chute to an induction heating furnace, heating the same to a prescribed temp., taking the bars from the furnace, and supplying the same to an isothermally holding device by means of timers. CONSTITUTION:Many steel bars 19 on a feed chute 3 are put by each piece into a coil-shaped quick induction type heater 5 by the 1st pusher 2. The bars 19 are heated to 800 deg.C in the heater 5 and are pushed out by the succeeding bars so as to be moved onto a chain conveyor 8 until the bars stop moving by contacting with a stop plate 9. The bars are transferred by the 2nd pusher onto a steel bar receiving and transferring part 11 where an open/shut door 16 is opened and are stored in an isothermally holding device 13. The steel bars are held at 700 deg.C in said device and are subjected to a softening heat treatment by spheroidization. The above-mentioned operations are automatically accomplished by means of timers T1-T4. Thus, the quick softening heat treatment of many steel bars is efficiently accomplished.

摘要： PURPOSE:To give an evenly spheroidized structure to a bar steel material by a short-period heat treatment in which a stranded bar steel material is subjected to an annealing treatment involving heating and cooling under specific conditions. CONSTITUTION:A bar steel material, e.g., of carbon steel for the structures of machinery, cold rolling, etc., is made into a strand form, and then heated to a target temperature of Ac1+30 deg.C to Ac1+150 deg.C at an average heating rate of 50 deg.C/min or more. Then, the bar steel material is held at the target temperature for 5min or less, cooled for 10min or less to the transformation point Ar1, and then cooled at an average cooling rate of 0.5 to 5 deg.C/min in a temperature region of Ac1 to 40 deg.C for spheroidization. Thus, high temperatures can be effectively utilized because the rate, time, and temperature of heating the bar steel material can be exactly controlled, so that a bar steel material having evenly spheroidized structure can be obtained by a short-period heat treatment.
