Thaum lub sij hawm tsim cov txheej txheem ntawm siab alumina cib, lub pores ntawm lub cev ntsuab yuav tsum tau tswj. Feem ntau hais lus, rau cov cib uas hnyav dua 15kg, tsis muaj qhov cua tuaj yeem tso tawm, tab sis rau cov cib siab alumina hnyav dua 15kg, tshwj xeeb tshaj yog cov hnyav tshaj 25kg, cua qhov yuav tsum tau tso tseg kom tso pa tawm tag nrho. . Tsis txhob tso cov pob zeb thiab bubbling ntawm cov cib thaum lub sij hawm tua.
1. Cov tsim high alumina hluav taws cib yog denser
Txhawm rau tswj cov porosity ntawm siab alumina cib, nws tseem ceeb heev uas yuav tsum siv lub tshuab xovxwm. Nws yog ib qho tsim nyog yuav tsum siv cov xov tooj sib txhuam ntau dua 630 rau molding. Cov alumina silica cib tsim nyob rau hauv txoj kev no yog denser thiab muaj qis porosity. Yog hais tias nws yog ib qho hnyav alumina cib ntau tshaj 50kg lossis 100kg, hydraulic xovxwm yuav tsum tau siv los tsim nws. Nws tsis yog yooj yim los siv tes molding. Vim tias phau ntawv sau ua kom siab tsis txaus, nws cuam tshuam rau cov txheej txheem ntawm lub cev cib.
Tsis txhob tso cua ntau dhau rau hauv siab alumina refractory cib uas hnyav tshaj 25kg. Koj tuaj yeem tshawb xyuas qhov hnyav ntawm lub cib thiab tawm ntawm 2-6 qhov sib faib rau saum npoo ntawm lub cib kom tso cai rau cov pa roj hauv lub siab alumina cib kom tag nrho tawm thaum ziab. Txwv tsis pub, bubbling, ob txheej txheej, los yog ntau txheej txheej yuav tshwm sim thaum lub sij hawm tua. Yog hais tias tus nqi ntawm delamination los yog blistering siab dhau lawm, nws yuav zoo li nce nqi ntau lawm.
2. High alumina bricks yog ntsia rau hauv lub kiln, sintered los yog muab tso rau hauv lub tsheb kiln
Thaum txhim kho, sintering los yog tso siab alumina hluav taws cib nyob rau hauv lub tsheb kiln uas hnyav dhau lawm, yuav tsum tau them nyiaj mloog mus rau, ua ntej, muab cov hluav taws xob channel, thiab thib ob, rau nruab lawv nyob rau hauv pem teb kom ntau li ntau tau, yog li ntawd. qhov hnyav siab alumina refractory hluav taws cib tuaj yeem ua tiav Sintering kom ntseeg tau tias sab hauv ntawm lub cev hnyav cib raug hlawv los ntawm thiab muaj kev ua tau zoo dua.
Txawm li cas los xij, thaum hnyav siab alumina cib tau muab tso rau ntawm txheej txheej sab saud rau kev tso tawm, kev saib xyuas yuav tsum tau them rau lub peev xwm thauj khoom ntawm qis txheej ntawm cib. High-alumina cib ntawm cov khoom sib txawv tsis tuaj yeem raug tso tawm, vim tias qhov kub thiab txias ntawm qhov sib txawv ntawm qhov zoo sib txawv. Yog tias nws qis dua cov khoom hnyav, cov txheej sab saud yuav raug rho tawm haujlwm. Cov nyhuv yog OK, tab sis qis dua high-alumina cib tau deformed thiab siv tsis tau. Yog tias qhov zoo ntawm cov cib qis qis dhau lawm, cov cib qis yuav tsis raug hlawv los ntawm. Thaum cov cib ntsuab tshwm sim, lawv yuav tsum tau rov ua dua tshiab, uas yuav ua rau lub voj voog ntau lawm thiab tus nqi.
