(TŽ, a. s.). The aim was to verify the possibility of deep desulphurization of steel in the basic 10-t electric arc furnace. Experimental procedures making use of the industrially produced synthetic slag were applied in the production of the high-alloy chrome steels and the middle-alloy tool steels, where the desulphurization, interms of thermodynamics, is a more demanding process than the chrome-nickel steel desulphurization. With the use of the technological processes it is possible to achieve low contents of sulphur in steel, below mass fraction 0.003 %. Achieving these contents depends on a suitable slag basicity, and, inparticular, on the ratio of CaO/Al2O3. Based on the analysis of the results, a critical factor significantly affecting the final content of the sulphur and thus the efficiency of the desulphurization of steel, the content of FeO in the reduction slag, is carefully considered. A higher MgO content in slag (up to w = 25 %) had no significant influence on the results of the steel desulphurization</dc:description><dc:description xml:lang="sl">Članek predstavlja rezultate eksperimentalnih talin, izdelanih v TŘINECKÉ ŽELEZÁRNY, a. s. (TŽ, a. s.). Namen raziskav je bil preveriti možnost močnega razžvepljanja jekla v bazični 10-tonski elektropeči. Izvršena je bila raziskava z uporabo industrijsko proizvedene sintetične žlindre pri proizvodnji močno legiranega kromovega jekla in srednje legiranega orodnega jekla, pri katerih je termodinamika razžvepljanja bolj zapletena kot pri razžvepljanju krom-nikljevih jekel. S primernimi tehnološkimi ukrepi je mogoče doseči v jeklu majhno vsebnost žvepla, nižjo od masnega deleža 0,003 %. Doseganje teh vsebnosti je odvisno od primerne bazičnosti žlindre in posebno še od razmerja CaO/Al2O3. Na osnovi analize rezultatov je bil določen kritični faktor, vsebnost FeO v redukcijski žlindri, ki močno vpliva na končno vsebnost žvepla in s tem na učinkovitost razžvepljanja. Večja vsebnost MgO (do masnega deleža 25 %) v žlindri nima večjega vpliva na razžvepljanje jekla</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-YBEE3Z16"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-YBEE3Z16" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-YBEE3Z16/3564df21-8ddc-4360-83e4-027f8e34795d/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-YBEE3Z16/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-YBEE3Z16" /></ore:Aggregation></rdf:RDF>
