Isisindo Esikhanyayo Silica Brick 1.2

Izitini ze-silica ezingasindi zisebenzisa i-silica echotshoziwe kahle njengempahla eluhlaza, futhi ubukhulu bezinhlayiyana zabo ezibucayi ngokuvamile abukho ngaphezu kuka-1mm, futhi izinhlayiya ezingaphansi kuka-0.5mm azikho ngaphansi kuka-90%. Izinto ezivuthayo zengezwa ezithakweni noma indlela yokukhiqiza igesi isetshenziselwa ukwakha isakhiwo esinezimbotshana, esibe sesixoshwa. Kungenziwa futhi imikhiqizo engashiswanga. Isetshenziswa ikakhulukazi ezingxenyeni ezihlukahlukene zama-kilns ezidinga ukufakwa kwe-insulation noma ukwehlisa isisindo ngaphandle kokuxhumana okuqondile nokuncibilika, ngaphandle komphumela wamagesi abhubhisayo, futhi ngaphandle kokushintsha kwezinga lokushisa okungazelelwe. Isetshenziswa emazingeni okushisa aphezulu futhi ayikwazi ukuthintana nezinto ezine-alkaline refractory. Kuye ngempahla, izinga lokushisa lokusetshenziswa kwalo liphakathi kuka-1200 no-1550 ℃.

Izitini ze-silica ezingasindi ziyizinto ezikhetheke kakhulu, ezisetshenziswa kakhulu embonini yengilazi nasembonini yensimbi. Ezimweni eziningi, izitini ze-silica ezingasindi nezitini eziminyene ze-silica zisetshenziswa njengezingxenye zesendlalelo sesakhiwo. Okuvame ukusetshenziswa embonini yeziko lengilazi, ikakhulukazi ukufakwa kwe-vault yesithando somlilo, ngaleyo ndlela kunciphisa ukulahlekelwa ukushisa nokwandisa ukusebenza kahle kwenqubo yokuncibilika. Embonini yokwenza insimbi, izitini ze-silica ezingasindi zisetshenziselwa ukulula kwezindonga zesithando somlilo esishisayo kanye nezindlu.

1. Izitini ze-silica ezingasindi zisetshenziswa embonini yengilazi - ukufakwa kwe-thermal of vaults

Enqubweni yokuncibilika kwengilazi, amazinga okushisa aphezulu afinyelelwa engxenyeni engezansi ephakanyisiwe ye-vault. Kuye ngohlobo lwengilazi, izinga lokushisa licishe libe ngu-1600°C. Isendlalelo esingasindi ngokuvamile siklanywa njengezendlalelo ezimbili noma ngaphezulu.

Izitini ze-silica ezingasindi zivezwa kakhulu kule mithwalo yokushisa. Kulindeleke ukuthi isendlalelo esisodwa se-vault (isakhiwo nesendlalelo esilula) sibe nezakhiwo ezifanayo noma ezifanayo zokunweba. Izitini ze-silica ezinobuningi obukhulu be-1250kg · m-3 noma 1000kg · m-3 zingahlangabezana nezidingo zesendlalelo esiminyene. Isendlalelo esilandelayo sisebenzisa izitini ze-silica ezinobuningi bokuminyana obungu-800Kg·m-3 noma 600kg·m-3.

Izitini ze-silica ezingasindi zingapakishwa ngokukhululekile ku-vault yesithando somlilo noma zihlanganiswe nobumba lomlilo we-silica. Awukho umthwalo wamakhemikhali ngesikhathi sokuphila kwenkonzo yesithando somlilo (iminyaka eminingana). Izitini ze-silica ezingasindi zisetshenziswa kakhulu ngenxa yokuthi ukwakheka kwamakhemikhali namaminerali olwelwesi olusebenzayo kuyafana nezitini eziminyene ze-silica ezisetshenziswa.

2. Izitini ze-silica ezingasindi zisetshenziswa embonini yensimbi - ama-hot blast furnaces

Izithando zomlilo ezishisayo zivame ukusetshenziselwa umoya oshisayo (obizwa ngokuthi i-blast furnace blast), oxhunywe ku-exhaust fan yesithando somlilo. Kuye ngokuma nendawo yesithando somlilo esishisayo, izinga lokushisa liphakathi kuka-1000 no-1300 ° C, futhi umoya oshisayo uphakathi kuka-2300 kuya ku-6500 m3 · min-1.

Lokhu kudinga ukubala ukuqhathanisa phakathi kwesithando somlilo esishisayo (ubukhulu bezingxenye ezihlukene nezindawo zokusetshenziswa) kanye nedome yengilazi yomlilo emazingeni ahlukene kanye nemithwalo ehlukahlukene, okugxile kuzakhiwo ze-thermomechanical. Okwesendlalelo esingasindi, ukuminyana kwevolumu okusetshenzisiwe ngu-1250kg·m-3 noma 1050kg·m-3 (ikakhulukazi ngenxa yamandla azo aphezulu)
