Abstract

PURPOSE: To simplify the deoxidization process and to prevnet the steel material from defects like as generation of flaws, etc., by constituting the deoxidizing alloy for the molten steel of a specified metallic composition in ordet to generate the interposition being not dendoritic.
CONSTITUTION: A suitable amount of an alloy, constiuted of 20W80 mol% Al, 8W 80 mol% Ti, and additionally one of Mn, Si, by 8W30 mol% or both of them by 16W60 mol%, is added to the molten steel in order to cause the deoxidization; hereby, the melting point of generated oxides is lowered, and the degree of supercooling is reduced. As a result, the dendoritic oxides disappear and the favorable oxides are generated. Besides, both of deoxidization speed and deoxidization capacity are not inferior as compared with the case employing only Al. If the Ti content exceeds 80%, the deoxidization speed is slowed down, and it is uneconomical; if the Ti content is less than 80%, the favorably formed oxides can not be obtained. As a result, the conventional troublesome deoxidization process becomes unnecessary.
