Daim ntawv thov thiab ua haujlwm ntawm lub cub tawg
Lub qhov cub qeeb mentshis yog hais txog lub teb lub taub dej (uas nquag paub tias lub ncov teb) thiab yog nyob rau cov qeb ntawm cov cuab yeej siv ua tsev. Lub ncov teb muaj peev xwm muab faib ua cov ncu zeb ua ntau ntxiv, cov tshuab nqus hlau ua kom sov thiab cov ua cov txiv qaub ua raws li cov khoom sib txawv. Cement ncu tsuas yog siv rau calcining xis mas clinker, muab faib ua ob pawg: cov txheej txheem qhuav cement ncu thiab txheej txheem ntub cement ncu. Metallurgical thiab cov qhov cub rau tshuaj lom yog siv rau kev sib nqus ntawm cov hlau ore-depleted ore hauv cov hlau thiab hlau cog hauv kev lag luam nws yog xim hlau; oxidizing ci ntawm chromium thiab nickel hlau ore; refractory cog ci siab alumina vanadium ore thiab txhuas cog ci clinker thiab txhuas hydroxide; tshuaj cog tsob ntoo lub hnub nyoog chromium ore Thiab chrome ore hmoov thiab lwm yam minerals. Txiv qaub ncu (piv txwv li cov txiv qaub ncu) yog siv los ci cov txiv qaub thiab cov nplaim taws dolomite siv hauv cov ntoo thiab hlau txov ntoo thiab nroj tsuag ferroalloy.
Daim ntawv thov kev lag luam
Lub qhov cub tawg tau siv dav hauv kev tsim kho cov khoom siv, ua hlau, tshuaj lom neeg kev lag luam, kev tiv thaiv ib puag ncig thiab ntau lwm cov chaw tsim khoom siv los siv cov khoom siv lub tog raj kheej rau kev siv tshuab, kho lub cev lossis tshuaj kho cov khoom siv khov. Cov khoom siv zoo li no hu ua kev sib hloov roj. Daim ntawv thov ntawm lub qhov cub teb muaj nyob rau hauv cov khoom siv cement ntau. Hauv 1824, Tus neeg ua haujlwm Askiv cement J Asp tsim ib txoj haujlwm ncaj qha ntsug; hauv 1883, German Dietz tau tsim txoj kev ncu ntau yam tsis tu ncua; 1885 British Lansham (ERansome) tau tsim lub tshuab hluav taws xob, muab tso rau hauv kev tsim khoom tom qab tau txais ntawv ntiag tug ntawm Tebchaws Askiv thiab Tebchaws Asmeskas, thiab sai sai tau txais txiaj ntsig kev lag luam ntau. Qhov tsim muaj ntawm lub tshuab ua teb tau ua cov kev lag luam cement ntxiv, thiab nws kuj tau txhawb nqa tib neeg' kev tshawb fawb txog kev siv cov tshuab ua teb lub cev. Tsis ntev, cov teb cog tau raug siv dav hauv ntau thaj chaw muaj kev lag luam, thiab dhau los ua qhov tseem ceeb hauv cov khoom lag luam, dhau los ua qhov tseem ceeb ntawm cov khoom lag luam. ntaus ntawv. Nyob rau hauv daim ntawv thov daim teb ntawm lub teb cub, lub lag luam cement muaj cov naj npawb coob.
Fais ntawm cov teb kiln
1. Nws cov txheej txheem kev ua haujlwm thiab kev ua haujlwm ntau saib xyuas qhov zoo, tsim tawm thiab tus nqi ntawm cov khoom lag luam." Ntev npaum li qhov kiln puv, yuav muaj kaum tawm lab tus" ;. Cov nkauj nkauj zoo nkauj no yog cov lus piav qhia txog ntawm qhov tseem ceeb ntawm lub cub tawg hauv kev tsim khoom.
2. Hauv kev lag luam tsim khoom siv hauv tsev, ntxiv rau forging cement clinker, lub tshuab ua kom lub pob zeb ua kom sov no tseem siv rau cov hmoov av calcining, limestone, thiab slag kom qhuav. Hauv kev tsim cov khoom siv refractory, lub tshuab ua kom sov lub forging raw khoom siv los tswj lub zog qhov loj thiab nce lub zog. , Thiab tom qab ntawd ua tiav rau cov duab.
3. Hauv cov txiaj ntsig kev ua haujlwm, lub tshuab ua kom lub tshuab ua kom lub zog loj siv los ua kom cov hlau nplaum thiab cov hlau tsis zoo los hloov cov hlau nplaum uas tsis muaj zog ntawm cov hlau los ua kom muaj zog hlau nplaum, uas tau txais txiaj ntsig zoo rau kev sib nqus.
4. Hauv kev lag luam chemical, cov txiv ntsej muag siv los ua cov dej qab zib, calcined phosphate fertilizer, barium sulfide, thiab lwm yam Nyob rau hauv 1960 s, American LapPle thiab lwm tus tau tsim cov txheej txheem tshiab rau kev tsim cov phosphoric acid siv siv rotary kiln. Txoj kev no muaj qhov zoo ntawm kev siv hluav taws xob tsawg, kev siv hluav taws xob tsawg, tsis muaj sulfuric acid thiab siv cov pob zeb phosphate tsawg.
5. Cov txheej txheem tag nrho cov khoom ntawm cov cement yog cov ntsiab lus raws li" ob qhov sib tsoo thiab ib rab phom" nyob rau hauv uas" ib tug tua" yog txheej txheem tua cov khoom siv raw uas npaj los ntawm kev sib tsoo rau hauv clinker hauv qab qhov kub ntawm lub cub tawg. Yog li ntawd, lub tshuab nqus teb yog lub cav loj hauv cov cement ntau lawm, feem ntau hu ua" plawv" ntawm MAAs Hoobkas.
6. Hais txog kev tiv thaiv ib puag ncig, cov teb chaws tau tsim lub ntiaj teb tau siv cov ncu zeb ua kom hlawv cov khoom pov tseg thiab cov khib nyiab uas muaj kev phom sij rau ntau dua 20 xyoo. Qhov no tsis tsuas yog txo thiab tsim kev puas tsuaj rau cov khoom pov tseg, tab sis kuj siv cov khoom pov tseg kom tau cov roj pov tseg cov hmoov av. Rov siv cov khoom pov tseg.
