Refractory zvinhu zve lime kiln
Refractory zvinhu zve lime kiln
Lime kiln inonyanya kukamurwa kuita sikweya kiln neraundi. Zvinoenderana nemhando yezvigadzirwa zvakapiswa, kune lime kilns uye ceramic kilns. Yakakamurwa kuita preheating zone, kupfura nzvimbo uye kutonhora nzvimbo.
Muchokwadi, tembiricha yekushandiswa kweiyo preheating zone pamusoro peiyi kiln haina kukwirira zvakanyanya, asi zvigadzirwa zvinogona kukonzera kubvongodzwa kukuru pazvidhinha zvinoramba kana zvigadzirwa zvapiswa, uye gasi rechoto rinokonzera kemikari yakakomba. ngura kune zvidhinha zvinoramba. Naizvozvo, isu tinofanirwa kutarisisa kune simba, density, kupfeka kusagadzikana uye kushora kuramba kwezvidhinha zvinoramba.
Kunyangwe iyo preheating zone haidi kutonhora kwakanyanya kwezvidhinha zvinoramba, zvinodiwa zvezvimwe zvinhu zvezvidhinha zvinoramba zvakanyanya. Mafekitari mazhinji anoshandisa zvidhinha zvakakwirira zvealuminium uye zvidhinha zvevhu, izvo zvakasiyana.
calcination nzvimbo. Iyo calcining zone inzvimbo inoitwa kemikari yezvidhinha zvinoramba zvichishandiswa mushishi yeraimu ndiyo yakasimba, uye nzvimbo yecalcining ndiyo nhanho ine tembiricha yepamusoro. Saka chenjerai kana mune zvidhinha. Iine yakanaka thermal shock resistance, corrosion resistance uye kupfeka kuramba. Shandisa dense high-aluminium zvidhinha.
Iyo calcination zone yakatanga kushandisa dense high-alumina refractory zvidhinha. Zvisinei, mumakore achangopfuura, kushandiswa kwe alkaline refractory zvidhinha kwave kuri nani, kunopindirana nemunda we lime gasi. Parizvino, nekuda kwezvikonzero zvekudhura, kune akawanda akakwira alumina zvidhinha, asi phosphate zvidhinha uye phosphate composite zvidhinha zvinobatsirawo zvakanyanya. Izvo zvinoenderana nemaitiro ekushandisa uye mutengo weimwe neimwe unit.
Nekudaro, hazvibviri kushandisa alkaline zvidhinha munzvimbo yekupfura. Muzvikamu zviri padyo nenzvimbo yepreheating uye inotonhorera zone, kupfeka kuramba kwakakosha pane kushora. Vazhinji vagadziri vachiri kushandisa yakakwirira-alumina refractory zvidhinha nekunaka kupfeka kusagadzikana uye yakakwirira refractory tembiricha.
Ipapo kune nzvimbo yekutonhora. Nekuti kana iyo quicklime ichipinda munzvimbo yekutonhodza, pachange paine kupisa kwakawanda kunoyerera kunodzoka nekudzoka munzvimbo yekutonhodza. Izvo zvidhinha zvinoramba zviri munzvimbo inotonhorera zvinofanirawo kuva neabrasion resistance, kudzivisa kukurumidza kutonhora uye kupisa, uye kuramba kusvuura. Asi kana shaft kiln ine dhayamita diki, vagadziri vazhinji vanosarudzawo zvidhinha zvevhu.
