Slow releasing potential deoxidizer
Slow-releasing potential deoxidizer introduction LF furnace is through the arc heating, bottom blowing mix, made such means as white slag, achieve deoxidizing desulfurization to effects such as inclusion, and cause a white is the realization of LF furnace slag many refining the important link of the function. So people have been looking to rapid, effective, low consumption and slag deoxidizing as deoxidizer, commonly used deoxidizer have C, Si, AL, Ba, C atmospheric pressure deoxidizing slow, Ba utilization rate is too low, Si deoxidizing ability is bad and increase the Si 】, only AL deoxidizing ability, faster and is widely adopted, but usually AL to processing into fine flocks to use, this method has two drawbacks: 1, in GaoWenLu gas and dust under negative pressure conditions, aluminium burning loss is big. 2, aluminum powder to join the metal aluminium uneven slag of aluminum enrichment, back to silicon back to phosphorus serious, easy to add AL. For this, we developed a slow-release deoxidizer, the purpose is (1), and slag quickly sparkling, form the submerged arc slag, shorten the slag sparkling submerged arc time; (2), uniform continuously melted and release the aluminum, for deoxidization of blast furnace slag; (3), a residue of slag ingredients in steel sundry has better capture and adsorption ability.
