Ziziphi iingxaki ezinokubakho izitena ezikhanyelayo ekusebenzeni kwezitofu zesamente?

Izitena ezixhathisayo ziyinxalenye ebaluleke kakhulu kwiziko lesamente. Ukusebenza okuqhelekileyo kwe-sement kiln ayinakuhlukaniswa nokukhuselwa kwezitena eziphikisayo. Ukuba izitena eziphikisayo zonakaliswe okanye zihlanjululwe, ziya kuchaphazela ngokuthe ngqo ukuveliswa kwemveliso yesitofu se-samente, kwaye kwiimeko ezinzulu, kuya kufuneka ukuba umise i-oven ukulungiswa. Ngoko ke, kubaluleke kakhulu ukuqonda izinto ezichaphazela ubomi benkonzo yezitena eziphikisayo. Namhlanje, makhe sithethe malunga nokuba zeziphi iingxaki ezinokuthi zenzeke kwizitena ezilahlayo xa i-ziko lesamente lisebenza?

umonakalo oomatshini

Xa i-sement kiln ijikeleza kwimveliso, amanqanaba ahlukeneyo oxinzelelo lomatshini aqulunqwa phakathi kwezitena eziphikisayo kwi-oven kunye nezitena eziphikisayo, ngoko izitena eziphikisayo ziya kuxutywa kwaye zijikwe. Ukuba i-cylinder ye-rotary kiln ikhubazekile, uxinzelelo lomatshini kwizitena ze-refractory lining ziya kwandiswa, ngakumbi uxinzelelo lomatshini kwibhanti yesondo lunzima. Ngoko ke, ngaphambi kokukhetha into efanelekileyo yokuchasa, kuyimfuneko ukuqonda ukunyanzeliswa komatshini we-rotary kiln, ukwenzela ukuba ukhethe into efanelekileyo yokukhusela ukukhusela.

kushushu kwaye kubanda

Xa i-rotary kiln isebenza, ukuba iqondo lokushisa lomlilo lihlala lidibana nokubanda ngokukhawuleza kunye nokushisa okukhawulezayo, izitena eziphikisayo ziya kuchaphazeleka ngamaqondo ahlukeneyo okutshatyalaliswa kwe-thermal, okwandisa umngcipheko wokuphulwa kwezitena eziphikisayo. Ngoko ke, xa izitena eziphikisayo zibhakwa eziko emva kokuba kugqitywe ukufakwa, inkqubo yokufudumeza kufuneka icothe, ukuze ukwandiswa kwegobolondo lomzimba wokwandisa izitena ezongezelelweyo kuya kudlala indima yembuyekezo yomzimba, eyona nto ingundoqo ukusetyenziswa kwezitena alkaline. Ukuba i-kiln ayikwazi ukubhaka ixesha elide kwimveliso yangempela, kwaye i-oven ifudumala kwaye ipholile ngokukhawuleza, izitena eziphikisayo ngokuqinisekileyo ziya kuhlanjululwa kwaye zonakaliswe, ezichaphazela kakhulu ubomi bayo benkonzo.

Ukutshintsha kwamafutha

Ukuba ubomi benkonzo yesitena esichasayo buya kuqinisekiswa kwaye umphumo oqinileyo wesikhumba kufuneka ugcinwe, ukuzinza kwe-thermal ngundoqo. Nangona kunjalo, kunzima ukugcina ukuzinza kwe-thermal ngenxa yokungaqiniseki kwezinto eziluhlaza kunye namafutha. Izibaso ezikrwada ngokubanzi zezitofu zesamente ngamalahle. Ngenxa yobunzima bokunikezelwa kwamalahle, umthamo wothuthu wamalahle uya kwahluka ukusuka kwi-32% ukuya kuma-45%. Ngenxa yokuguquguquka komgangatho wamalahle, kuchaphazela ukunamathela kwesikhumba se-kiln, kwaye ulusu lwe-kiln lulula ukudibaniswa kumgangatho womzimba wezitena. Ukuqhwala. Ngokukodwa kwimeko yesithando somlilo esihlala siqalwa kwaye simisiwe, ukukhuselwa kwesikhumba somlilo kuya kulahleka, kwaye umgca wezitena eziphikisayo uya kuba nefuthe kwi-corrosion yeekhemikhali, okunciphisa ukuxhathisa ukukhathala kwe-thermal kunye nokunciphisa kakhulu ubomi benkonzo.

Ezi zingasentla zezinye zeengxaki eziqhelekileyo ekusebenzeni kwezitofu zesamente. Le mizekelo iya kuchaphazela ngokuthe ngqo ubomi benkonzo yezitena eziphikisayo. Kufuneka uhlawule ngakumbi xa ukhetha izitena ezilahlayo okanye izitofu zesamente. Ukukhethwa okuchanekileyo kunye nokusebenza okuchanekileyo kwezitena eziphikisayo kunokwandisa ubomi bayo benkonzo. Indlela yenkqubela phambili.
