Izitini ze-Magnesia carbon ziwuhlobo lwe-carbon composite refractory engashiswanga, ekhiqizwa nge-magnesium oxide ye-alkaline oxide ene-high-melting-point (2800 ℃), kanye ne-carbon material enephuzu eliphezulu lokuncibilika okunzima ukuguguleka yisithando somlilo njenge-slag. izinto zokusetshenziswa, futhi yengeza zonke izinhlobo ze-non-oxides addititive kanye ne-carbon binding agent. I-Magnesia carbon brick inezici ze-porosity ephansi, ukumelana nokuguguleka kwe-slag, ukumelana nokushisa okushisayo namandla aphezulu okushisa. Njengohlobo lwe-refractory eyinhlanganisela, izitini zomlilo we-magnesia zisebenzisa ukugqwala kwe-slag okuqinile kwe-magnesia kanye nokuhamba okuphezulu kwe-thermal kanye nokunwebeka okuphansi kwekhabhoni ngendlela efanele, kungenza umonakalo omkhulu wokumelana ne-spalling okubi kakhulu kwe-magnesia.
Izitini zekhabhoni ye-Magnesia izingxenye eziyinhloko yi-magnesium oxide ne-carbon, lapho okuqukethwe kwe-magnesium oxide kungu-60~90% kanye nokuqukethwe kwekhabhoni ngu-10~40%. Lolu hlobo lwenziwe ngezinhlayiyana ze-magnesia ezihlanzekile, izinto zekhabhoni, itiyela, iphimbo noma inhlaka njengezinto zokusetshenziswa ngokusebenzisa ukushisa okuphezulu kokubhaka. Ngakho-ke izitini zekhabhoni ze-magnesite zinezakhiwo zokumelana nokugqwala kwe-slag, ukumelana nokushaqeka okushisayo, ukuqhutshwa kwe-thermal nokunye.
Ngokwamasu okuhlanganisa abandayo ne-ejenti ebopha itiyela eyingxube iba lukhuni futhi ithole amandla adingekayo, ngaleyo ndlela yakha ikhabhoni ye-isotropous vitric. Izitini zekhabhoni ye-Magnesia zenziwe nge-agent ebopha iphimbo, ene-plasticity ephakeme yokushisa ephezulu ngenxa yokwakhiwa kwesakhiwo se-anisotropic graphitization coke enqubweni ye-pitch carbonation. Lolu hlobo lwekhabhoni alubonisi i-thermoplasticity engasusa ngokufanelekile inani lokucindezeleka ohlelweni lokudubula okufakwe kulayini noma ukusebenza.

Izitini zekhabhoni ze-Magnesia zisetshenziselwa ikakhulukazi ama-linnings of converter, isithando somlilo sikagesi-arc kanye nesithando somlilo esiqondile se-arc kagesi, umugqa we-slag wensimbi yensimbi nezinye isikhundla. futhi ingasetshenziselwa isithando somlilo esiyisisekelo se-oxygen, umugqa we-slag wesithando somlilo we-ladle nendawo eshisayo yesithando somlilo se-arc kagesi.
Imboni ye-RS refractory njengenye yezinkampani ezihamba phambili zokukhiqiza izitini zezitini ze-magnesite, ingahlinzeka ngezitini zekhabhoni ze-magnesia kumakhasimende anonjiniyela abangochwepheshe, ubuchwepheshe bokukhiqiza obuthuthukisiwe kanye nenkonzo enhle ngaphambi kokudayiswa kanye nangemva kokuthengisa. Ifektri ye-RS refractory ikhethekile ngezitini zomlilo we-magnesite carbon iminyaka engaphezu kwengu-20. Uma unesidingo esithile sesitini se-magnesia carbon, xhumana nathi mahhala, ukuthengisa kwethu kuzokuphendula ekuqaleni.
