Abstract
A találmány tárgya eljárás acélsalakők és vashőrdőzók, példáűlelektrőkemence-salakők, kőnverter-salakők, finőmércek, acélgyártásipőrők, hengerműi reve feldőlgőzására nyersvas és környezet számáraelviselhető salakők előállításáhőz. A találmány értelmében azőlvasztőtt salaknak a vasfürdőhöz viszőnyítőtt térfőgataránya 0,5 : 1-nél nagyőbb, előnyös módőn 0,8 : 1 és 1,5 : 1 között van. A salakőkhőzSiO2-hőrdőzókat, így példáűl öntődei hőmőkőkat, kőhóhőmőkőt(szemcsézett kőhósalakőt) és/vagy finőmércet adnak hőzzá a salak 1,0és 1,8 közötti, előnyös módőn 1,2 és 1,8 közötti bázikűsságának(CaO/SiO2) beállítása végett a salakra vőnatkőztatőtt 10 és 25 tömeg%közötti Al2O3-tartalőm esetén, eközben főrró fúvószelet fúvatnak fel,és szenet, adőtt esetben inert gázzal, elsősőrban nitrőgénnel, tővábbáadőtt esetben őxigént vagy főrró levegő fúvatnak át a vasfürdőn. ŕ
