Mea fa'afu
manatu:
O se vasega o mea e le fa'ameamea e le u'amea ma le fa'asao e le itiiti ifo i le 1580°C.Refractoriness e faasino i le Celsius vevela lea o le refractory cone faataitaiga tetee le gaioiga o le vevela maualuga e aunoa ma le faamaluluina ma le liusuavai i lalo o le tulaga e leai se uta.Ae ui i lea, naʻo le faʻamatalaga o le refractoriness e le mafai ona faʻamatalaina atoatoa mea faʻafefe, ma 1580 ° C e le faʻamaoni.Ua faauigaina nei o mea uma e mafai ona faʻaaogaina i totonu o se siosiomaga vevela maualuga e taʻua o mea faʻafefe.Refractory mea e masani ona faʻaaogaina i metallurgy, vailaʻau vailaʻau, suauʻu, gaosiga masini, silicate, malosiaga ma isi fanua tau alamanuia.O i latou e sili ona tele i le alamanuia metallurgical, faʻamauina mo le 50% i le 60% o le aofaʻi o gaosiga.
aafiaga:
E faʻaaogaina mea faʻamaʻi i vaega eseese o le tamaoaiga o le atunuʻu e pei o uʻamea, uʻamea e le o ni uʻamea, tioata, sima, ceramics, petrochemicals, masini, boilers, alamanuia mama, eletise eletise, alamanuia militeri, ma isi mea, ma o mea taua taua e fa'amautinoa le fa'agaioiina o le gaosiga ma le atina'eina fa'atekonolosi o pisinisi o lo'o i luga.E faia se sao taua ma e le mafai ona suia i le atinaʻeina o gaosiga o fale gaosi oloa maualuga.
Talu mai le 2001, faʻamalosia e le atinaʻeina vave o alamanuia vevela maualuga e pei o uʻamea ma uʻamea, uʻamea nonferrous, petrochemicals, ma mea faufale, o le alamanuia refractory o loʻo tumau pea le tuputupu aʻe lelei ma ua avea ma gaosiga tele ma le faʻatau atu o mea faʻafefe i totonu o le. lalolagi.I le 2011, o le gaosiga o le gaosiga a Saina e tusa ma le 65% o le aofaʻi o le lalolagi, ma o lona gaosiga ma le faʻatauga o loʻo faʻatulagaina muamua i le lalolagi.
O le atina'eina o fale gaosi oloa e feso'ota'i vavalalata ma le fa'atumauina o punaoa o minerale a le atunu'u.Bauxite, magnesite ma graphite o mea tetele ia e tolu.O Saina o se tasi lea o le lalolagi e tolu e sili ona tele le au fa'atauina atu o le bauxite, le tele o le lalolagi fa'aagaga o magnesite, ma le tele o le fa'atauina atu o kalafi.O alagaoa mauoa ua lagolagoina ai mea fa'asa'o a Saina mo le sefulu tausaga o atina'e vave.
Faatasi ai ma le vaitaimi o le "Fuafuaga Lona Lua a le Lima Tausaga", o Saina o loʻo faʻavavevaveina le faʻaumatiaina o le gaosiga tuai ma le maualuga o le malosi.O le a taulaʻi atu le alamanuia i le atinaʻeina ma le faʻalauiloaina o ogaumu fou e faʻasaoina ai le malosi, atinaʻeina o tekinolosi faʻasao malosi, puleaina o le malosi, puleaina o le faʻaogaina o le "tolu otaota" ma le faʻaogaina o punaoa o le "tolu otaota" Toe faʻaaogaina, ma isi. toe fa'aaogaina o puna'oa ma le toe fa'aogaina o mea fa'ato'a pe a uma ona fa'aoga, fa'aitiitia otaota fa'amama, fa'aleleia le fa'aogaina atoatoa o puna'oa, ma fa'alauiloa atoatoa le fa'asaoina o le malosi ma le fa'aitiitia o le fa'asa.
O le "Faiga Faʻavae o Atinaʻeina o Alamanuia Refractory" o loʻo faʻaalia ai o le faʻaaogaina o mea faʻafefe i totonu o le fale gaosi oloa a Saina e tusa ma le 25 kilokalama i le tone o le sila, ma o le a pa'ū i lalo ifo o le 15 kilokalama i le 2020. I le 2020, o oloa faʻamaʻi a Saina o le a umi le ola. , sili atu le malosi-mamafa, leai se filogia, ma faʻaogaina.O oloa o le a fetaui ma manaʻoga o le atinaʻeina o le tamaoaiga o le atunuʻu e pei o metallurgy, mea fau fale, vailaʻau, ma atinaʻe faʻatupulaia, ma o le a faʻateleina mea faʻapitoa o oloa auina atu i fafo.
E tele ituaiga ma fa'aoga 'ese'ese mea fa'aoga.E mana'omia le fa'avasegaina fa'asaienisi mea fa'asaienisi e fa'afaigofie ai su'esu'ega fa'asaienisi, filifiliga sa'o ma pulega.E tele auala fa'avasegaga mo mea e fa'asa'o, e aofia ai le fa'avasegaina o uiga fa'ama'i, fa'avasegaga o minerale vaila'au, fa'avasegaga o le gaosiga, ma le fa'avasegaina o meafaitino.
Fa'avasegaga:
1. E tusa ai ma le tulaga o refractoriness:
Mea masani refractory mea: 1580 ℃ ~ 1770 ℃, maualuga mea refractory mea: 1770 ℃ ~ 2000 ℃, vasega faapitoa refractory mea:> 2000 ℃
2. E mafai ona vaevaeina mea refractory i:

3. Fa'avasegaina i meafaitino kemisi:
Acid refractory, neutral refractory, alkaline refractory
4. Fa'avasegaga e tusa ai ma vaila'au vaila'au vaila'au
O lenei fa'avasegaga auala e mafai ona fa'avasega sa'o le tu'ufa'atasiga ma uiga o mea eseese refractory.O se fa'avasegaga masani metotia i le gaosiga, fa'aoga, ma su'esu'ega fa'asaienisi, ma e malosi lona fa'aogaina.
Silica (silika), alumini silicate, corundum, magnesia, magnesia calcium, alumini magnesia, magnesia silicon, carbon composite refractories, zirconium refractories, refractories faapitoa
6. Fa'avasegaina o mea e le fa'atusaina (fa'avasegaina e tusa ai ma le fa'aogaina)
Castables, faʻapipiʻi coatings, ramming mea, palasitika, umia mea, mea faʻataʻitaʻiga, mea smear, mago mea vibrating, castables tafe, refractory slurries.
O mea fa'aletonu e masani ona aofia ai le alumina, chromium oxide po'o le carbon.O le oloa corundum o loʻo i ai le sili atu i le 95% alumina o se mea faʻamalo maualuga maualuga ma le tele o faʻaoga.
Chiping Wanyu Alamanuia ma Fefa'ataua'iga Co., Ltd., fa'atūina i le 2010, fa'apitoa i le gaosiga o mea fa'aofuofu ma fa'asao: oneone pa'epa'e pa'epa'e, pa'u lelei, ma oloa fa'asologa o oneone.
