Abstract: The present disclosure provides a carbide refining method of a high-carbon high-alloy steel. The carbide refining method of a high-carbon high-alloy steel includes the following steps: formulating a raw material according to chemical element compositions of the high-carbon high-alloy steel, and smelting to obtain a high-carbon high-alloy molten steel; performing an overheat treatment on the high-carbon high-alloy molten steel to Tm+(50˜100)° C., to obtain a high-carbon high-alloy melt, and making the high-carbon high-alloy melt to be deposited in a preset water-cooled copper mold at a speed of 30˜160 g/s by an inert gas, to obtain a high-carbon high-alloy billet through solidification molding; and performing a heat treatment process on the high-carbon high-alloy billet.

Abstract: This application discloses an information processing method, apparatus, and device, and relates to the field of artificial intelligence (AI). The method includes displaying a user interface, the user interface comprising a received virtual item packet, and the virtual item packet comprising topic information; displaying the topic information of the virtual item packet; receiving an interaction message corresponding to a second user account, the interaction message being matched with target information to request to receive a virtual item in the virtual item packet, and the target information being the topic information or information associated with the topic information; and receiving the virtual item in the virtual item packet in response to matching the interaction message and the target information.
