I-Castable ye-High-Alumina Refractory: Iipropati eziphambili kunye nokusetyenziswa kwemizi-mveliso

Kwimisebenzi yobushushu obuphezulu kwimizi-mveliso, izinto ezikhuselayo nezinokuthenjwa zibalulekile ukuze izixhobo zihlale ixesha elide kwaye zikhuseleke.I-castable ye-alumina ephezulu enganyangekiyo—enomthamo we-alumina oyi-45%–90%—ibalaseleyo njengokhetho oluphezulu, ngenxa yokusebenza kwayo okugqwesileyo kwiindawo ezinobushushu obuphezulu. Apha ngezantsi kukho uhlalutyo olufutshane lweempawu zayo eziphambili kunye nokusetyenziswa kwayo.

1. Iipropati eziphambili ze-High-Alumina Refractory Castable

1.1 Ukumelana Okuqinileyo Nobushushu Obuphezulu

Igcina ulwakhiwo luluqilima kwi-1600–1800℃ ixesha elide (ngokumelana nexesha elifutshane neencopho eziphezulu), iphumelela ngaphezu kwezinye iindlela ze-alumina ezisezantsi. Kwimisebenzi engama-24/7 efana nokwenza intsimbi okanye ukuvelisa isamente, oku kunciphisa ukuvalwa kokugcinwa kwaye kwandisa ubomi bezixhobo.

1.2 Amandla Oomatshini Aphezulu

Ngoxinzelelo oluyi-60–100 MPa kubushushu begumbi, iphatha ubunzima kunye nezinto ezinkulu ngaphandle kokuqhekeka. Okubaluleke kakhulu, igcina amandla phantsi kobushushu, imelana nobushushu—ilungele izitofu zokunyibilikisa iglasi apho amaqondo obushushu etshintshatshintsha khona, nto leyo enciphisa ukusilela kwelayini ebiza kakhulu.

1.3 Ukumelana nokuKhukuliseka kunye nokuGxobhoza
Ulwakhiwo lwayo oluxineneyo lumelana nokukhukuliseka kweekhemikhali (umz., i-slag enyibilikisiweyo, iigesi ze-asidi) kunye nokuguguleka komzimba. Kwii-converters zentsimbi, iyamelana nentsimbi enyibilikisiweyo ehamba ngokukhawuleza; kwii-incinerators zenkunkuma, ikhusela iigesi ze-asidi flue, inciphisa iimfuno zokulungisa kunye neendleko.

1.4 Ukufakwa okulula kunye nokuguquguquka
Njengomgubo omkhulu, ixutywa namanzi/i-binder ibe ludaka olunokugalelwa, ifakelwe kwiimo ezingaqhelekanga (umz., amagumbi esitovu esenziwe ngokwezifiso) izitena ezenziwe kwangaphambili ezingenakulinganiswa nazo. Yenza ulwelo olungenamthungo, isusa "ukuvuza komlilo" kwaye ifanele izakhiwo ezintsha okanye izinto ezintsha.

2. Izicelo eziphambili zeShishini

2.1 Intsimbi kunye neMetallurgical

Isetyenziswa kwiilinings ze-blast furnace (bosh/hearth, >1700℃), iilinings ze-electric arc furnace (EAF), kunye neeladle—zimelana nokukhukuliseka kwentsimbi enyibilikisiweyo kunye nokulahlekelwa bubushushu. Ikwasebenzisa ii-furnace ezivuselelayo zokunyibilikisa i-aluminium/copper.

2.2 Isamente kunye neGlasi
Ilungele iindawo ezitshisa i-oven yesamente (1450–1600℃) kunye nee-linings ze-preheater, ezimelana nokurhawuzelelwa yi-clinker. Kwimveliso yeglasi, igcina iitanki ezinyibilikisayo (1500℃), ixhathisa ukugqwala kweglasi enyibilikisiweyo.

2.3 Unyango lwaMandla kunye neNkunkuma
Ii-oven zebhoyila ezisebenzisa amalahle (ezimelana nothuthu oluphumayo) kunye namagumbi okutshisa inkunkuma (ngokumelana nobushushu obuyi-1200℃ kunye neemveliso eziphuma kwi-asidi), ukuqinisekisa ukusebenza okukhuselekileyo, okungasebenzi ixesha elide.

2.4 I-Petrochemical kunye neKhemikhali
Isebenzisa ii-crackers zomphunga (1600℃, ukuvelisa i-ethylene) kunye nee-ovens ezirostayo iiminerali (umz., isichumisi), ezimelana nomphunga we-hydrocarbon kunye neekhemikhali ezirhabaxa.
