Abstract

Esillä oleva keksintö saa aikaan lisättyä saantia lisäaineella parannetussa tai metalliseoksella parannetussa teräs sulassa. Tämä saavutetaan additiivisiin metalliseoksiin sekoitetuilla pelkistävillä jauheilla. Pelkistävä jauhe reagoi hapen kanssa, siten poistaen hapen tältä alueelta. Metalliseoksen tai lisäaineen alue rikastuu, siten parantaen saantia terässulassa. (Kuva 4)The present invention provides increased yield in an additive-enhanced or alloy-enhanced steel melt. This is achieved by using reducing powders mixed with the additive alloys. The reducing powder reacts with oxygen, thereby removing oxygen from that region. The alloy or additive region becomes enriched, thereby improving yield in the steel melt. (Figure 4)
