Qhov chaw ua haujlwm ntawm iav kiln yog qhov hnyav heev, thiab kev puas tsuaj ntawm cov khoom siv hauv cov khoom siv refractory feem ntau cuam tshuam los ntawm cov hauv qab no.
(1) Tshuaj erosion
iav kua nws tus kheej muaj ib tug loj piv ntawm SiO2 Cheebtsam, yog li nws yog chemically acidic. Thaum cov khoom siv hauv ob sab phlu yog nyob rau hauv kev sib cuag nrog cov iav kua, los yog nyob rau hauv qhov kev txiav txim ntawm cov roj-kua theem, los yog nyob rau hauv qhov kev txiav txim ntawm cov hmoov av thiab hmoov av tawg, nws cov tshuaj corrosion yog hnyav heev. Tshwj xeeb tshaj yog nyob rau hauv qab thiab sab phab ntsa ntawm da dej, qhov twg raug molten iav kua yaig nyob rau hauv lub sij hawm ntev, cov tshuaj erosion yog heev hnyav. Lub checker bricks ntawm regenerator ua haujlwm nyob rau hauv qhov kub thiab txias fume, roj thiab plua plav yaig, cov tshuaj lom neeg puas tsuaj kuj muaj zog. Yog li ntawd, thaum xaiv cov khoom siv refractory, qhov kev tiv thaiv corrosion yog qhov tseem ceeb tshaj plaws uas yuav tsum tau xav txog. Lub molten da dej hauv qab refractory thiab sab phab ntsa refractory yuav tsum yog acid. Nyob rau hauv xyoo tas los no, fused cam khwb cia AZS series cib yog qhov kev xaiv zoo tshaj plaws rau qhov tseem ceeb ntawm cov da dej molten, xws li zirconia mullite cib thiab zirconium corundum cib, ntxiv rau, zoo silicon cib kuj tseem siv.
Noj rau hauv tus account ntawm cov qauv tshwj xeeb ntawm cov iav kiln, da dej phab ntsa thiab hauv qab yog ua los ntawm cov refractory cib loj es tsis txhob me me cib, yog li cov khoom siv feem ntau yog fused cam khwb cia.
(2) Mechanical scouring
Mechanical scouring feem ntau yog qhov muaj zog scouring ntawm molten iav ntws, xws li lub caj pas ntawm lub melting seem. Qhov thib ob yog lub tshuab scouring ntawm cov khoom siv, xws li cov khoom siv them qhov chaw nres nkoj. Yog li, refractories siv ntawm no yuav tsum muaj lub zog txhua yam thiab zoo scouring kuj.
(3) Kub kub ua haujlwm
Kev ua haujlwm kub ntawm lub khob cij yog siab li 1600 ° C, thiab qhov kub hloov pauv ntawm txhua qhov yog nruab nrab ntawm 100 thiab 200 ° C. Nws tseem yuav tsum tau muab sau tseg tias lub hauv paus kiln ua haujlwm nyob rau hauv lub sij hawm ntev-kub kub. iav kiln refractory cov ntaub ntawv yuav tsum tiv taus kub yaig, thiab yuav tsum tsis txhob paug iav kua.
