摘要： The present invention is to provide a method for shot peening for producing a compressive residual stress that exceeds 60% of the yield strength at 0.2% offset without using stress shot peening. Shot media are peened onto a processed steel that has an amount of retained austenite in a range between 5 to 30%, and any change in the amount of retained austenite is controlled to be in a range of 2 to 30% before and after shot peening to produce the compressive residual stress in the processed steel.

摘要： Provided is an automatic pouring method whereby even a tilting automatic pouring device can pour at high speed, accommodating high-speed molding on a high-speed molding line. Said method includes: a process wherein a pouring tank, which can hold an amount of molten metal sufficient for multiple pours, is tilted forward, thereby pouring the molten metal from inside said tank into a casting mold; a process wherein the pouring tank is tilted backward, thereby halting the aforementioned pouring into the casting mold; and a process wherein a set of casting molds, including the casting mold for which the aforementioned pouring had completed, are moved at intervals. During the period from the beginning of the process in which molten metal is poured into the casting mold to the end of the process in which the set of casting molds is moved at intervals, whenever the weight of molten metal in the pouring tank is less than a prescribed weight, molten metal is continually supplied to the pouring tank by tilting a holding furnace forward.
