Abstract: The present embodiment is a method of recycling reinforcing fibers, the method comprising: providing a tank having at least a first protective layer disposed on an outer peripheral surface of a liner and a liner, the first protective layer being configured such that a resin-impregnated fiber bundle including a reinforcing fiber bundle and a first matrix resin is wound around the liner; and a second protective layer formed of the first matrix resin on the first protective layer; removing a portion of the second protective layer to expose a winding end portion of the resin-impregnated fiber bundle; peeling the exposed winding end portion; and pulling the peeled winding end portion to draw out the resin-impregnated fiber bundle.

Abstract: A metal purifying method having: a local heating step of heating an aluminum-based molten metal in a first region on a molten metal surface of the aluminum-based molten metal; and a local low pressure step of lowering the pressure in a second region on the molten metal surface to a pressure lower than the pressure in the first region. The second region is different from the first region. This allows a specific element to be vaporized from the second region to purify the aluminum-based molten metal. The specific element is one or more of Zn, Mg, or Pb having a saturated vapor pressure higher than that of Al. This is effective not only in a purifying method for removing a specific element from an aluminum-based molten metal but also in a method of recovering a specific element, which can be a resource, from an aluminum-based molten metal.

Abstract: A hydrogen gas burner structure includes a first cylinder tube, a second cylinder tube, a third cylinder tube, and an ignition device. An inside of the first cylinder tube is configured such that hydrogen gas flows. A space between the first cylinder tube and the second cylinder tube is configured such that a first combustion-supporting gas containing oxygen gas flows. A space between the second cylinder tube and the third cylinder tube is configured such that a second combustion-supporting gas containing oxygen gas flows. The ignition device is configured to ignite mixed gas. The tip of the first cylinder tube is located upstream of the tips of the second and third cylinder tubes in a gas flow direction in which the hydrogen gas and the first combustion-supporting gas and the second combustion-supporting gas flow.

Abstract: A molten metal temperature control method includes: with respect to relations among a spheroidization distance traveled by a molten metal of an alloy from a nozzle tip to a position where the molten metal turns into droplets, the temperature of the molten metal inside the crucible, and a pressure acting on the molten metal inside the crucible, obtaining a relation between the temperature and the spheroidization distance at a predetermined pressure, and setting a predetermined temperature range of the temperature; measuring a spheroidization distance when discharging the molten metal from the crucible at the predetermined pressure, and specifying a temperature corresponding to the measured spheroidization distance; and comparing the specified temperature and the predetermined temperature range, and when the specified temperature is outside the predetermined temperature range, controlling the specified temperature so as to be within the predetermined temperature range by adjusting the temperature inside the crucible.
