Title:
CARBIDE REFINING METHOD FOR HIGH-CARBON AND HIGH-ALLOY STEEL
Document Type and Number:
WIPO Patent Application WO/2023/213334
Kind Code:
A1
Abstract:
The present application provides a carbide refining method for high-carbon and high-alloy steel, relating to the field of alloy steel manufacturing methods. The carbide refining method for high-carbon and high-alloy steel comprises the following steps: preparing raw materials according to the chemical element composition of a high-carbon and high-alloy steel, and melting to obtain a high-carbon and high-alloy liquid steel; superheating the high-carbon and high-alloy liquid steel to Tm+(50-100)°C, to obtain a high-carbon and high-alloy melt, depositing the high-carbon and high-alloy melt in a preset water-cooled copper mold at a speed of 30-160 g/s with an inert gas, and solidifying to obtain a high-carbon and high-alloy ingot; subjecting the high-carbon and high-alloy ingot to a heat treatment process. The carbide refining method for high-carbon and high-alloy steel of the present application can obtain high-carbon and high-alloy steel having a dense structure and fine carbides.
