Nxiba iLiner yeCeramic enganyangekiyo yesikwere

I-liner ye-ceramic yesikwere ichazwa ngeempawu ezine eziphambili:

Ukuqina: I-Mohs 9, ukuxhathisa ukukrazula kwi-quartz kunye neentsimbi ezininzi. Intsimbi yiMohs 5–6 kuphela.

Ukuxinana: Ubuninzi bobuninzi Kukhulu okanye bulingana ne-3.63 g/cm³, ukufunxa amanzi Ngaphantsi okanye ilingana ne-0.01% - akukho kungena kwamanzi, akukho mkhenkce{2}}umonakalo wokunyibilikisa.

Ukuchasa impembelelo: Ukuqina kokwaphuka ukuya kuthi ga kwi-5.70 MPa·m¹/² (ibakala le-TW92S), ukunciphisa ukuqhekeka phantsi komthwalo onzima.

Ubume bezinto ezininzi: Ifumaneka njengeetyhubhu ezicacileyo, iibhloko ezidityanisiweyo, iityhubhu ezithe chatha, kunye noyilo olunamaqhuqhuva okanye imingxuma.

Izinto eziphathekayo, uLwakhiwo kunye nokuVeliswa

Ilayini yeceramic esisikweri yenziwe ngomgubo ophezulu{0} owenziwe nge-alumina. Amabanga avela kwi-92% ukuya kwi-99% ye-Al₂O₃, kunye nokucoceka okuphezulu okubonelela ukuchasana okukhulu kunye nomngcipheko ophantsi wokungcola. Umgubo umanzi-wenziwa ngokwesayizi yamasuntswana afanayo, emva koko utshizwe-womisiwe. Ukubumba kusebenzisa ukucinezela okomileyo okanye ucinezelo olubandayo lwe-isostatic (CIP) ngokuxhomekeke kubungakanani bethayile. I-CIP iqinisekisa ukuxinana okufanayo kwityhubhu yonke, ukuphelisa iindawo ezibuthathaka ezibangela ukunxiba okungalinganiyo. Emva kokwenziwa, imizimba eluhlaza iyomiswa kancinane ukunqanda iintanda{10}}ezincinci, emva koko zitshiswe kwitonela kwi-1500-1550 degree. Ngexesha lokucwina, iinkozo ze-alumina ziyafiyiza, zizuze ukuxinana kwesambuku ngaphezulu kwe-3.63 g/cm³ kunye nokufunxwa kwamanzi ngaphantsi kwe-0.01%. Ibhetshi nganye iphantsi kolawulo olungqongqo lomgangatho: ukwakheka kweekhemikhali okungqinwe yi-XRF, ubulukhuni buvavanyiwe nge-ASTM C1327 nganye, kunye nokutshekishwa kobukhulu obunegeyiji ezilinganisiweyo. Iithayile ezinetshiphu, iintanda, okanye ezingaphandle{19}ko{20}}zokunyamezela imilinganiselo ziyaliwa.

Into eyahlula iTecera kukusetyenziswa kocinezelo lwe-isostatic kuzo zonke iityhubhu ezinkulu kuno-50 mm, kunye neemilo ezingaphezulu kwama-2,000 zesiqhelo - iityhubhu ezicatshulweyo, iibhloko ezidityanisiweyo, iityhubhu ezinamaqhuma angqukuva, kunye noyilo oluyifeni{3} lwemilo egobileyo.

Izinto eziluncedo kwimveliso

Ngenxa yokuba i-square ye-ceramic liner igxininiswe ngokupheleleyo ngokufunxa kwamanzi Ngaphantsi okanye ilingana ne-0.01%, akukho lulwelo lwenkqubo olungena kwi-ceramic - i-slurries ene-acidic ayinakuyenza buthathaka, kwaye imozulu ebandayo ayikwazi ukuyiqhekeza. Ngenxa yokuba ubulukhuni bayo be-Mohs bu-9, iyaxhathisa ukukrwela kwi-quartz-intsimbi ekrwada etyebileyo kunye namasuntswana aqinileyo, ngokungafaniyo nentsimbi ekhukula ngokukhawuleza. Ngenxa yokuba iTecera ibonelela ngoyilo oludityanisiweyo kunye nolwe tapered, iliner isusa izithuba ezithe ngqo{5}}zemigca eziye zibe ngamajelo okhukuliseko – utshintsho olulula olunokuphinda kabini okanye kathathu ubomi benkonzo kwizicelo zesantya esiphezulu{6}. Iintambo ze-alumina ze-mosaic zandisa ubomi benkonzo ngamaxesha angama-2-3 xa kuthelekiswa nentsimbi eqhelekileyo okanye i-polymer wear liners, ukuphucula ngokuthe ngqo ixesha kunye nokunciphisa iindleko zokusebenza.

Iimeko zeSicelo

Ukwembiwa kwemigodi: I-Chute liners, iibhokisi zokutya kwenkanyamba, iindawo zokudlulisa umhambisi. Umgodi wobhedu eMzantsi Ostreliya walungisa intsimbi ekrwada kwiitoni ezingama-2,200 ngeyure ngokusebenzisa{3}}isantya esiphezulu sokuhamba ngaphantsi kwe-chute. Iilayini zangaphambili zigqitywe kwiiveki nje ezimbalwa. Emva kokufaka iilayini ze-ceramic zesikwere, ubomi benkonzo bandiswa ukuya kuthi ga kwiinyanga ezili-12.

Ukuveliswa kwamandla: Ii-chutes zokutya zokucoca amalahle, iihophu zokuphatha uthuthu. Isixokelelwano sokuhambisa amalahle somzi-mveliso wamandla obushushu sifuna ukugcinwa amaxesha ama-2-3 ngenyanga. Emva kokufaka i-alumina ceramic liners, ukugcinwa kwehle ukuya kanye ngekota kwaye iindleko zokusebenza zehle ngama-40%.

Isamente: Imigqomo yokutya okukrwada, iichute zeclinker, imibhobho yokukhupha ilitye. Umzi-mveliso wesamente waseBrazil ubone ubomi be-clinker chute bukhula ukusuka kwiinyanga ezisi-8 ukuya ngaphezulu kweenyanga ezingama-28.-

Izingqusho zentsimbi: Ii-chute zezityalo ze-Sinter, ii-coke hoppers, imigqomo yokutya yesithando somlilo. Iilayini ze-ceramic zesikwere zimelana nobushushu obuphezulu (ukuya kuthi ga kwi-400 degree) kunye ne-abrasive sinter dust.

Ukuodola

I-Tecera ibonelela nge-92%, 95%, 97%, 99%, kunye ne-ZTA ye-square liner ze-ceramic ezinobukhulu ukusuka kwi-6 mm ukuya kwi-50 mm, kwi-plain, interlocking, kunye neemilo eziqhelekileyo. Iisampulu zasimahla zovavanyo olonakalisayo. Ixesha lokukhokela 2{11}}3 iiveki eziqhelekileyo, 4-6 iiveki ngokwesiko. Ukuthunyelwa kwehlabathi jikelele kunye nokupakishwa kwebakala lokuthumela ngaphandle. Phendula phakathi kweentsuku ezimbini zokusebenza.

Iifayile ezishisayo: nxiba ilineni ye-ceramic enganyangekiyo yesikweri, iTshayina inxinzelela abavelisi belayini ye-ceramic yesikwere, ababoneleli, umzi-mveliso
