Title:
METHOD FOR PRODUCING ALLOY STEEL
Document Type and Number:
WIPO Patent Application WO/2018/043835
Kind Code:
A1
Abstract:
The present invention relates to a method for producing alloy steel, comprising the steps of: producing first alloy steel in a holding furnace; maintaining the first alloy steel at a melting point or higher in the holding furnace; and mixing the first alloy steel and molten steel to produce second alloy steel having an alloy content lower than that in the first alloy steel, whereby ferroalloys are consecutively melted and stored during the production of alloy steel and thus can be restrained or prevented from decreasing in temperature.
