Cov khoom siv refractory rau txiv qaub kiln

Txiv qaub kiln feem ntau muab faib ua square kiln thiab round kiln. Raws li kev faib tawm ntawm cov khoom raug rho tawm haujlwm, muaj cov txiv qaub kilns thiab ceramic kilns. Nws muab faib ua preheating zone, firing zone thiab txias zone.

Qhov tseeb, kev siv qhov kub thiab txias ntawm thaj chaw preheating nyob rau sab saum toj ntawm cov txiv qaub kiln tsis siab heev, tab sis cov khoom siv raw yuav ua rau muaj kev puas tsuaj loj ntawm cov cib refractory thaum cov khoom raug kub hnyiab, thiab cov roj rau hauv qhov cub yuav ua rau muaj tshuaj lom. corrosion mus rau refractory bricks. Yog li ntawd, peb yuav tsum xyuam xim rau lub zog, ceev, hnav tsis kam thiab corrosion kuj ntawm refractory bricks.

Txawm hais tias thaj tsam preheating tsis xav tau qhov kub ntawm refractory bricks, qhov yuav tsum tau rau lwm yam khoom ntawm refractory bricks yog nruj heev. Ntau lub chaw tsim khoom siv siab alumina cib thiab av nplaum cib, uas txawv.

thaj chaw calcination. Lub cheeb tsam calcining yog thaj chaw uas cov tshuaj tiv thaiv ntawm refractory cib siv nyob rau hauv cov txiv qaub kiln yog qhov muaj zog tshaj plaws, thiab calcining cheeb tsam kuj yog theem uas kub tshaj plaws. Yog li ceev faj thaum koj muaj cib. Nws muaj qhov zoo thermal shock resistance, corrosion kuj thiab hnav tsis kam. Siv ntom ntom-alumina cib.

Lub cheeb tsam calcination pib siv ntom ntom high-alumina refractory cib. Txawm li cas los xij, nyob rau hauv xyoo tas los no, kev siv cov alkaline refractory bricks tau zoo dua, zoo ib yam nrog cov roj av lime. Tam sim no, vim yog vim li cas tus nqi, muaj ntau lub siab alumina cib, tab sis phosphate cib thiab phosphate composite cib kuj tseem ceeb heev. Nws nyob ntawm tus cwj pwm siv thiab tus nqi ntawm txhua chav.

Txawm li cas los xij, nws tsis tuaj yeem siv alkaline cib hauv thaj chaw tua hluav taws. Nyob rau hauv qhov chaw ze rau thaj tsam preheating thiab cua txias, hnav tsis kam yog qhov tseem ceeb tshaj qhov kev tiv thaiv corrosion. Ntau lub tuam txhab tseem siv high-alumina refractory bricks nrog zoo hnav tsis kam thiab siab kub refractory.

Tom qab ntawd muaj qhov chaw txias. Vim hais tias thaum lub quicklime nkag mus rau hauv qhov chaw txias, tseem yuav muaj ntau cov cua sov ntws rov qab mus rau hauv qhov chaw txias. Cov cib refractory nyob rau hauv qhov chaw txias yuav tsum muaj kev puas tsuaj, tsis kam ua kom txias thiab cua sov, thiab tiv thaiv tev. Tab sis thaum cov ncej kiln muaj ib txoj kab uas hla me me, ntau manufacturers kuj xaiv av nplaum cib.
