Vim hais tias zinc volatilization kiln yog ib tug dynamic kiln. Lub qhov cub yog nyob rau hauv qhov kub thiab txias tsis tu ncua kev khiav hauj lwm lub xeev. Cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg nyob rau hauv ob sab phlu yog khaus thiab complex, thiab lub hauv ob sab phlu yog hnyav hnyav. Kev xaiv ntawmrefractory bricksrau hauv ob sab phlu yuav tsum tau ceev faj heev. Tshwj xeeb phosphate bricks thiab magnesia-alumina-chromium cib yog ob qho tib si hauv ob sab phlu zinc volatilization kilns thiab yog ua los ntawm cov ntaub ntawv tsim nyog.
Lub zinc volatilization kiln muaj lub ntim ntim loj, uas yuav ua rau lub tog raj kheej deformation; Nws yog ib qho tsim nyog los tsim ib hom cib tsim nyog thiab xaiv refractory hluav taws cib ntawm cov khoom tsim nyog; cov refractory firebricks siv muaj ntau seams thiab yog yooj yim corroded los ntawm slag, yog li sim siv qhuav qhuav; Tsis tas li ntawd, lub hauv ob sab phlu yuav raug cuam tshuam los ntawm kev sib xyaw ua ke ntawm kev yaig thiab txo cov cua, thiab cov khoom siv refractory ntawm lub hauv ob sab phlu yuav erode sai heev. Nws yog ib qho tsim nyog yuav tau xaiv cov tshuaj tiv thaiv corrosion thiab hnav-resistant refractories bricks. Av nplaum cib corrode ceev tshaj plaws, thaum magnesia cib, magnesia-alumina cib, chrome slag cib thiab magnesia-chrome cib corrode maj mam.
Nyob rau hauv xyoo tas los no, tshwj xeeb phosphate cib tsim los ntawm cov tuam ntxhab ntawm phosphate cib, uas yog, phosphate cib nrog qhov ntom ntawm ntau tshaj 2.9, tau siv zoo heev. Txawm li cas los xij, magnesia-alumina-chromium cib kuj tau siv zoo heev hauv cov volatilization kilns. Qhov sib txawv ntawm ob cov ntaub ntawv ntawm refractory cib yog tias ib qho yog chemically bonded cib thiab lwm yam yog magnesia bricks, thiab lwm yam yog tus nqi. Tus nqi tshwj xeeb phosphate cib tseem nyob ze li ntawm 2, 000 qis dua li ntawm magnesia-alumina chrome cib. Yuan. Vim nws cov nqi, kev siv cov phosphate cib tshwj xeeb muaj qhov zoo sib xws.
Yog tias koj xaiv magnesia-alumina-chrome cib, nws yog qhov ua tau. Lawv muaj lub neej ua haujlwm ntev thiab kev hloov pauv tsawg. Hais txog tus nqi, tshwj xeeb phosphate cib yog tus nqi qis thiab kuj yog ib qho kev xaiv zoo rau cov ntaub ntawv kub. Tam sim no, muaj ntau yam tshwj xeeb phosphate cib nyob rau hauv kev ua lag luam.
Raws li rau cheeb tsam preheat thiab txias tsam cib, siab alumina refractory cib los yog zoo tib yam phosphate cib yuav siv tau. Nyob rau hauv xyoo tsis ntev los no, siab alumina cib thiab zoo tib yam phosphate cib tau siv. Nyob rau hauv cov nqe lus ntawm kev ua lag luam piv piv, phosphate cib zoo tib yam yog siv ntau dua. Yog hais tias tshwj xeeb phosphate cib siv nyob rau hauv high-temperature cheeb tsam, vim hais tias lawv yog ua los ntawm tib yam khoom raws li cov cib nyob rau hauv high-temperature cheeb tsam, lub kiln hauv ob sab phlu cua yuav zoo ib yam. Ntxiv mus, phosphate cib yog hnav-tiv taus ntau dua li cov alumina cib siab thiab muaj lub neej ua haujlwm ntev dua.
