Lub iav tank rauv melts horizontally, thiab cov kua nto txav horizontally. Ntxiv nrog rau qhov ntws ntws, peb-theem interface yog eroded loj heev. Lub khob hluav taws xob melting rauv yog vertically melted, thiab feem ntau ntawm lawv yog txias saum melting. Lub iav kua nto yog npog los ntawm ib txheej ntawm raw khoom, thiab muaj tsawg dua peb-theem interfaces. Vim hais tias nws yog vertically melted, qhov yaig ntawm lub pas dej ua ke phab ntsa bricks yog tsis concentrated nyob rau hauv peb-theem interface, tab sis lub zuag qhia tag nrho yaig, yog li qhov tsis muaj zog txuas ntawm lubfused zirconium corundum cibyog qhov tawg ntawm kev yaig.
Nyob rau hauv kev pom ntawm kev yaig mechanism ntawm fused cam khwb cia zirconium corundum cib, cov ntsiab lus ntawm Na2O nyob rau hauv cov khoom raw muaj pes tsawg leeg ntawm AZS bricks yuav tsum nruj me ntsis tswj ua ntej. Lub teb chaws tus qauv xav kom cov ntsiab lus ntawm Na2O hauv 33 # WS yog tsawg dua 1.45%, thiab cov ntsiab lus ntawm Na2O hauv 41 # WS yog tsawg dua 1.3%. Tus qauv ntawm peb lub tuam txhab hluav taws xob melting rauv xav kom cov ntsiab lus ntawm Na2O hauv 33WS tsawg dua 1.35%, thiab cov ntsiab lus ntawm Na2O hauv 41#WS yog tsawg dua 1.05%.
Rau kev yaig ntawm cov hluav taws xob hluav taws xob hauv pas dej ua ke, qhov sib piv ntawm cov riser rau cov khoom cib yuav tsum ncav cuag 1.5: 1. Lub siab ntawm cov khoom siv riser tuaj yeem txo qhov seem ntawm qhov pores hauv cov khoom cib, txhim khu lub peev xwm tiv thaiv kev yaig ntawm cov khoom cib ntawm qhov chaw nres nkoj, thiab yuav tsum tsis muaj qhov pom tseeb shrinkage kab noj hniav kom nyob twj ywm ntawm qhov chaw nres nkoj.
Rau kev yaig ntawm cov hluav taws xob hluav taws xob hauv pas dej ua ke phab ntsa, cov pob qij txha cib raug tshuaj xyuas nruj me ntsis thaum lub sij hawm sib dhos ntawm cov fused zirconium corundum cib, thiab yuav tsum tau qis dua 0.3mm. Qhov sib txawv ntawm qhov sib txawv ntawm txhua qhov yog nruj me ntsis tswj thaum lub sij hawm ci ci txheej txheem los xyuas kom meej qhov nruj ntawm cov pob qij txha cib thaum lub sij hawm tus txheej txheem, yog li txo qhov nkag ntawm cov pa roj, tiv thaiv kev tsim ntawm peb-theem interface ntawm lub cib pob qij txha, thiab txo tus nqi ntawm cov pa nkag. erosion ntawm qhov chaw hauv daim duab 3.
Rau kev yaig ntawm cov hluav taws xob hauv lub pas dej ua ke phab ntsa, qhov dav ntawm fused zirconium corundum bricks yuav tsum tsawg dua 400mm thaum lub sij hawm tsim txheej txheem. Qhov dav dhau lawm yuav ua rau cov khoom cib kom muaj ntau qhov shrinkage kab noj hniav thiab xoob sab hauv; qhov sib piv ntawm cov riser rau cov khoom cib yuav tsum ncav cuag 1.5: 1, thiab cov khoom siv cib zoo tuaj yeem txhim kho los ntawm kev siab thiab tso pa tawm; txo cov rwb thaiv tsev nyob rau theem tom ntej ntawm kev ua haujlwm ntawm qhov cub, thiab txo qhov kev yaig los ntawm kev txo qhov kub ntawm cov khoom cib.
