Alumina Magnesia Carbon Piliki

O mea refractory na faʻaaogaina i le laina slag o le ladle muamua na tuʻufaʻatasia faʻatasi ma piliki magnesia-chrome, faʻafefe eletise ona tuʻufaʻatasia lea ma piliki magnesia-chrome ma isi piliki alkaline maualuga. Ina ua maeʻa le faʻaaogaina o piliki MgO-C i luga o tagata liliu, na faʻaaogaina foi piliki MgO-C i le laina o le faʻamama o le ladle faʻamamaina, ma na maua ai iʻuga lelei. o loʻu atunuu ma Iapani e masani ona faʻaogaina piliki MgO-C faʻapipiʻi resin ma le carbon content o le 12% i le 20%, aʻo Europa e masani ona faʻaaogaina piliki MgO-C faʻapipiʻi asphalt, ma le carbon content e tusa ma le 10%.

O le Kokura Steel Works a le Sumitomo Metal Corporation i Iapani na faʻaaogaina piliki MgO-C ma MgO i totonu o le 83% ma le C anotusi o le 14-17% e sui ai piliki magnesia-chrome faʻapipiʻi tuusaʻo i le VAD slag line, ma le ola tautua o le slag. laina na faʻateleina mai le 20 taimi i le 30-32 taimi [9]. O le LF refining ladle o Sendai Steel Plant i Iapani na faʻaaogaina piliki MgO-C e sui ai piliki magnesia-chrome, ma o le ola tautua o le laina slag na faʻateleina mai le 20-25 taimi i le 40 taimi, maua ai taunuuga lelei. Osaka Ceramics Refractory Co., Ltd. na su'esu'eina aafiaga o le carbon content ma le antioxidant type i le fa'ama'iina o le fa'ama'i, fa'ama'i ma'a ma le maualuga o le vevela o piliki MgO-C. O le suʻesuʻega o loʻo faʻaalia ai o piliki MgO-C o loʻo faia i le faʻafefiloi o magnesia fused ma sintered magnesia, faʻatasi ai ma le 15% phosphorus graphite ma se vaega itiiti o le magnesium-aluminum alloys e avea ma antioxidants, e iai se aoga lelei. A faʻaaogaina i le 100-ton LF ladle slag line, o le faʻaleagaina e faʻaititia i le 20-30% faʻatusatusa i piliki MgO-C ma le carbon content o le 18% ma e leai se antioxidant, ma o le fua faatatau o le tafia o le 1.2-1.3 mm / ogaumu [1].

Talu ai ona ua fa'aaogaina piliki MgO-C i lo'u atunu'u nai lo piliki magnesia-chrome, o le fa'aogaina atoatoa o le fa'aoga ua manino. O le 300t ladle slag line a le Baosteel Group Corporation na amata faʻaaogaina piliki MT-14A magnesia-carbon ia Iulai 1989, ma o le ola laina slag na tumau pea i luga atu o le 100 taimi; o le 150T ogaumu eletise ladle slag laina faʻaaogaina piliki magnesia-carbon maualalo e faʻafefe ai uamea, ma le vevela vevela o le 1600 ℃ ~ 1670 ℃, lea na ausia ai taunuʻuga manino.

O la matou kamupani faʻapitoa i le gaosiga o piliki carbon magnesia, piliki carbon alumini-magnesia, piliki e le o le carbon mo ladle faʻamamaina, alumini-silicon carbide carbon piliki mo tane torpedo, ma piliki magnesia fou e leai se carbon ma refractories amorphous eseese, e pei o le toe faaleleia. ma mea fa'afana mo mea fa'aliliu, ogaumu eletise ma lale. Matou te tuʻuina atu foʻi mea faʻapipiʻi vibration, e pei o piliki ea ladle, piliki nofoa piliki ea-permeable, piliki nofoa pusi ma vaega faʻapipiʻi. Ua matou atiina ae i totonu o se pisinisi refractory atoatoa tuufaatasia suʻesuʻega o mea mata, faagasologa loloto ma fefaatauaiga. O le matou fale su'esu'e o lo'o i ai se seti atoa o su'ega ma su'esu'ega meafaigaluega. O a tatou meafaigaluega e mafai ona gaosia mea mata, oloa maeʻa, suʻega ma asiasia, ma atiina ae oloa fou. Matou te talitonu o le faasaienisi ma tekinolosi o lo matou taiala. O le mea lea, ua matou mauaina tekinolosi faʻapitoa i le fale ma fafo, faʻaauau pea ona faʻaleleia le tulaga lelei o oloa, faʻasaienisi ma faʻatekonolosi mea ma mautu faʻapitoa, ma faʻaleleia atili ai le gaosiga o tekonolosi ma faʻafouina pea a matou meafaigaluega gaosiga. Matou te tuʻuina atu le atoaga o auaunaga faʻapitoa e tusa ai ma le tele ma faʻataʻitaʻiga faʻapitoa o tagata liliu, ogaumu arc eletise ma ladle e tusa ai ma manaoga o tagata faatau.
