Dura Rinodzivisa Kuchinja
Ruzivo rweChigadzirwa
Dura rinonyungudutsa,inozivikanwawo sedhaka remoto kana zvinhu zvekubatana (hupfu), zvinoshandiswa sezvigadzirwa zvekubatanidza zvinoramba kushanda. Zvishandiso zvekugadzira zvidhinha zvinogona kukamurwa kuitaivhu, aluminium yakawanda, silicon uye magnesium refractory mortar, nezvimwewo.
Inonzidhaka risingadzorekiYakagadzirwa nehupfu hwe clinker husingapindiki uye ivhu repurasitiki sechinobatanidza uye chinobatanidza purasitiki. Simba rayo patembiricha yemumba rakaderera, uye kuumbwa kwe ceramic bonding patembiricha yepamusoro kune simba guru. Ne hydraulicity, air hardening kana thermo-hardening materials sechinobatanidza, zvinonzimakemikari anosunga dhaka risingadzoreki, sezvinoitwa pasi pekuumbwa kwekushisa kwekusunga kweceramic kusati kwagadzirwa imwe nzira yemakemikari uye kuoma.
Hunhu hwedhaka risingadzoreki:purasitiki yakanaka, kuvakwa kuri nyore; simba rakasimba rekubatana, kuramba ngura kwakasimba; kuramba kwakasimba, kusvika 1650℃±50℃; kuramba slag kupinda; kugona kupisa kupisa.
Dura rinoputika rinoshandiswa zvakanyanya muchoto checoke, chitofu chegirazi, chitofu cheblast, chitofu chekupisa, simbi, indasitiri yezvinhu zvekuvaka, michina, petrochemical, girazi, boiler, simba remagetsi, simbi nesimbi, simende nezvimwe zvitofu zvemaindasitiri.

1. Dura remvura rinoita kuti mvura irambe ichinaya rakagadzirwa nevhu
Mashandisirwo Akakosha:Yakakodzera kuisa zvidhinha zvinoramba kutonhora zvakavakirwa pavhu munzvimbo dzine tembiricha ≤1350℃, dzakadai sezvikamu zvemaovheni emaindasitiri, maflue, machimuni, zvikamu zvepasi zvezvitofu zvinopisa, uye mabhoyira—zvose munzvimbo dzine ngura shoma, tembiricha yepakati kusvika yakaderera.
Zvimiro:Mutengo wakaderera, kushanda zvakanaka, kuramba kupisa nekutonhodza nekukurumidza; hazvina kukodzera nzvimbo dzine tsvina yakanyungudutswa zvakanyanya/dzine ngura yakawanda.
2. Dura rine alumina yakawanda rinodzivisa kudonha
Zvishandiso zvikuru:NM-50/NM-60: Yakakodzera zvidhinha zvine alumina yakawanda (Al₂O₃ 55%~65%), zvinoshandiswa muchikamu chepakati chekupisa kwemakiln (1350~1500℃), zvakaita semakiln eceramic, maoven ekupisa esimbi, uye nzvimbo dzekuchinja dzesimende dzinotenderera; NM-70/NM-75: Yakakodzera zvidhinha zvine alumina yakawanda (Al₂O₃ ≥70%) kana zvidhinha zve corundum, zvinoshandiswa muchikamu chekupisa kwakanyanya (1500~1700℃), zvakaita sema linings e blast furnace, ma converter e steelmaking tapholes, ma regenerator e glass kiln, uye ma linings e calcium carbide furnace.
Zvimiro:Kuramba kwakasimba, kuramba kusviba kwetsvina zvichienzaniswa nevhu; kana Al₂O₃ iri yakawanda, kuramba kusviba kwekupisa kwakanyanya uye kuramba kuvhurika kwevhu kwakasimba.
