Qhov cuam tshuam ntawm kev kub ntxhov siab rau lub sijhawm ua haujlwm ntawm high alumina refractory bricks
Thaum qhov kub thiab txias hloov, kev ntxhov siab thermal tshwm sim vim qhov tsis muaj peev xwm ntawm cov khoom kom nthuav tawm tag nrho thiab ywj pheej vim yog qhov kev txwv sab nraud ntawm cov khoom thiab kev sib koom ua ke ntawm cov khoom sab hauv. Refractory high-alumina bricks nthuav thermally ntawm qhov kub thiab txias thiab muaj kev cuam tshuam rau axial expansion thiab kneading kev ntxhov siab, uas yog ib qho tseem ceeb rau refractory high-alumina bricks qhib thiab kaw kilns. Piv txwv li, magnesia-chromium lossis spinel cib, qhov nthuav dav ntawm 1400 degree tuaj yeem suav ua 1.6%. Qhov kev nthuav dav ntawm 198mm ntev refractory high-alumina cib tuaj yeem ncav cuag 3.17mm. Nrog rau qhov kev nthuav dav loj, yog tias lub nplhaib sib koom tsis tuaj yeem tswj tau kom raug, loj dhau lossis me dhau yuav ua rau cov refractory siab alumina cib kos, poob thiab poob tawm, ua rau lub neej luv luv ntawm cov refractory siab alumina cib.
Cov nyhuv ntawm cov neeg kho tshuab kev ntxhov siab rau lub sijhawm ua haujlwm ntawm siab alumina cib
Axial txav ntawm lub qhov cub rotary. Lub tshuab hluav taws xob tig tau txais kev txhawb nqa los ntawm txoj siv sia, txhawb nqa lub log, thiab txhawb nqa cov menyuam. Nws cov axis yuav tsum yog txoj kab txuas ntawm qhov nruab nrab ntawm txhua ntu ntu ntawm lub voj voog ntawm qhov cub, thiab nws yuav tsum yog txoj kab ncaj nraim. Txawm li cas los xij, tom qab lub tshuab hluav taws xob tau teeb tsa thiab ib feem ntawm lub thoob tau hloov pauv, lossis lub tshuab hluav taws xob lub cev tau dhau los ntawm lub sijhawm tom qab kev ua haujlwm, lub axis ntawm lub cev lub cev yuav hloov pauv vim muaj kev cuam tshuam ntawm thermal load thiab load. Tom qab ua haujlwm ntev, lub log tsheb siv thiab cov menyuam yuav hnav, cov menyuam yuav sib txawv ntawm sab nraud mus rau sab hauv, thiab kev ntxhov siab ntawm txhua qhov kev txhawb nqa yuav hloov. Tshwj xeeb tshaj yog thaum cov kev txhawb nqa muaj kev ntxhov siab heev, nws yog ib qho yooj yim los tsim cov menyuam bearing bush. Hlawv kev puas tsuaj, txawv txav los yog tawg ntawm qhov chaw ntawm lub log siv thiab cov menyuam, uas ua rau lub axial deflection ntawm lub cev kiln, ua rau cov refractory siab alumina bricks yuav extruded thiab deformed, ua rau tawg los yog poob tawm. Tom qab cov high-alumina refractory cib puas lawm, cov duab yuav tob dua.
