Vim li cas Sintering Temperature Matters rau High -Alumina Cib
Sintering kub yog ib qho tseem ceeb tshaj plaws ntau lawm yam cuam tshuam rau qhov zoo ntawmHigh Alumina Cib. Rau cov neeg yuav khoom thoob ntiaj teb, cov tsos ntawm cov cib refractory feem ntau yog thawj qhov uas lawv pom. Lub teeb daj lossis daj -dawb saum npoo yuav zoo li huv si thiab ntxim nyiam, thaum lub cib tsaus yuav tshwm sim tsis tshua pom kev. Txawm li cas los xij, hauv daim ntawv thov refractory, qhov tsos yuav tsum tsis txhob yog tus qauv nkaus xwb rau kev txiav txim siab zoo.
Cov txheej txheem sintering ncaj qha cuam tshuam rau cov qauv sab hauv, qhov ntom ntom, lub zog, ntim ruaj khov thiab kev pabcuam lub neej ntawm siab -alumina cib. Lub cib raug rho tawm haujlwm tau zoo tuaj yeem ua tau zoo nyob rau hauv siab -kub rauv, kilns thiab cov khoom siv thermal. Ib qho hauv qab - cib raug rho tawm haujlwm yuav zoo li du ntawm qhov chaw, tab sis nws tuaj yeem tsim teeb meem loj thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv kev hloov pauv kub.
Tsawg-Tsub Sintering: Zoo dua qhov tshwm sim tab sis qis qis
Thaum lub sintering kub tsis tshua muaj, siab -alumina cib feem ntau qhia ib tug sib dua xim thiab smoother nto. Los ntawm qhov pom kev pom, cov cib no yuav zoo li ntxim nyiam dua. Lawv cov npoo tuaj yeem pom zoo, thiab qhov saum npoo yuav zoo li huv dua piv nrog cov cib raug rho tawm ntawm qhov kub siab dua.
Txawm li cas los xij, qis -kub sintering feem ntau txhais tau hais tias cov ntaub ntawv raw tsis tau ua tiav. Cov qauv sab hauv yuav tsis ntom txaus, thiab kev sib txuas ntawm cov khoom yuav tsis muaj zog. Yog li ntawd, lub cib yuav muaj zog mechanical zog, tsis zoo hnav tsis kam thiab txo tsis kam mus rau spalling.
Rau qee qhov chaw ntawm lub qhov cub zoo li qub, qhov twg tsis muaj kev ntxhov siab thiab tsis muaj thermal poob siab, qhov qis dua - raug rho tawm haujlwm cib kuj tseem siv tau yog tias nws cov ntaub ntawv kev ua tau raws li qhov yuav tsum tau ua. Tab sis rau qhov xav tau ntawm cov chaw ua cua sov, qhov tsos ib leeg tsis tuaj yeem lav qhov kev ua tau zoo.
Siab -Tsub Sintering: Xim tsaus tab sis muaj zog ua haujlwm
Ntawm qhov tsim nyog siab dua sintering kub, cov khoom siv raw hauv siab -alumina cib teb ntau dua. Lub cib qauv ua denser thiab ruaj khov. Qhov no txhim kho qhov txias crushing zog, refractoriness nyob rau hauv load, hnav tsis kam thiab tsis kam mus ntim hloov thaum lub sij hawm kev pab cuam.
Siab -kub sintered cib yuav tshwm xim daj lossis sib sib zog nqus daj -dawb. Lawv cov xim saum npoo tej zaum yuav tsis ci li qis - cov khoom kub kub raug rho tawm haujlwm, tab sis cov tsos tsaus nti no feem ntau txuas nrog kev sib xyaw ua ke zoo dua. Rau cov neeg yuav khoom uas xav tau cib rau siab - kub thiab siab -load ua haujlwm thaj chaw, qhov kev ua tau zoo ntawm qhov kev ua tau zoo no tseem ceeb dua li xim.
Lub qhov dej -sinteredRefractory Cibtuaj yeem tiv taus thermal cycling, tshuaj tua kab mob thiab kev ua haujlwm ntev - lub cub tawg. Qhov no tseem ceeb tshwj xeeb hauv kev lag luam xws li cement, steel, txiv qaub, ceramics thiab tsis yog -ferrous metallurgy.
Secondary Expansion Risk nyob rau hauv qab -Cov cib raug rho tawm haujlwm
Ib qho teeb meem loj tshwm sim los ntawm qhov tsis txaus sintering yog qhov kev nthuav dav thib ob. High-alumina cib feem ntau yog tsim los ntawm bauxite thiab lwm yam alumina- cov khoom siv raw. Cov khoom siv raw no ib txwm muaj kev hloov pauv theem thiab ntim hloov thaum lub sijhawm cua sov.
Yog hais tias lub cib tsis yog tag nrho sintered thaum lub sij hawm tsim khoom, ib feem ntawm qhov kev hloov pauv no tuaj yeem txuas ntxiv tom qab lub cib tau teeb tsa hauv qhov cub. Thaum siv tiag tiag, lub cib yuav nthuav dav dua thaum raug kub siab. Qhov kev nthuav dav thib ob no tuaj yeem tsim kev ntxhov siab ntawm cov cib lossis nruab nrab ntawm cov cib hauv ob sab phlu thiab lub plhaub ntawm lub cub tawg.
Nyob rau hauv cov xwm txheej hnyav, lub qhov cub hauv ob sab phlu tuaj yeem tawg, xoob, tev tawm lossis tawg. Qhov tshwm sim tuaj yeem ua rau lub neej luv luv, kev kho ntau zaus thiab txawm tias tsis tau npaj kaw. Rau cov neeg yuav khoom, tus nqi tiag tiag ntawm tus nqi qis - zoo cib tsis yog tsuas yog tus nqi yuav khoom xwb, tab sis kuj yog tus nqi saib xyuas thiab cov khoom lag luam poob los ntawm cov kab tsis ua haujlwm.
Vim li cas Rotary Kilns Yuav Tsum Muaj Sintered Bricks
Rotary kilns muab qhov xav tau ntau dua rau siab -alumina cib ntau dua li ntau lub qhov cub zoo li qub. Thaum lub sijhawm ua haujlwm, lub cev lub cev tig tsis tu ncua thiab muaj kev nthuav dav thermal, kev ntxhov siab thiab cov khoom siv. Lub refractory hauv ob sab phlu yuav tsum nyob ruaj khov nyob rau hauv ob qho tib si kub thiab txav.
Yog tias nyob rau hauv - cov cib raug rho tawm haujlwm tau siv rau hauv lub tshuab hluav taws xob, qhov kev nthuav dav thib ob tuaj yeem ua rau muaj kev phom sij tshwj xeeb. Lub plhaub kiln nthuav dav thaum lub sijhawm ua haujlwm, thaum lub cib kuj tseem tuaj yeem nthuav vim tsis tiav sintering. Qhov no tuaj yeem ua rau muaj kev ntxhov siab txawv txav hauv ob sab hauv. Thaum qhov kev ntxhov siab dhau ntawm lub cib tsis kam, kev sib tsoo los yog hauv ob sab phlu puas yuav tshwm sim.
Yog li ntawd,Rotary Kiln Refractory Cibyuav tsum muaj txaus sintering, ruaj khov ntim, zoo zog thiab txhim khu kev qha thermal poob siab kuj. Hauv daim ntawv thov no, cov neeg yuav khoom yuav tsum tau them nyiaj ntau rau cov ntaub ntawv ua tau zoo dua li cov xim xim.
Yuav ua li cas manufacturers txiav txim siab qhov tseeb sintering kub
Ib tug kws tsim tshuaj paus tsis teem lub sintering kub random. Txoj kev tua hluav taws kom raug yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm cov khoom siv raw. Cov khoom sib txawv ntawm bauxite tuaj yeem muaj cov ntxhia sib txawv, qib impurity, particle loj faib thiab sintering tus cwj pwm.
Ua ntej loj ntau lawm, manufacturers feem ntau ua raw khoom kuaj, sim firing thiab kev soj ntsuam kev ua tau zoo. Trial firing helps determine whether the selected temperature can achieve good density, proper shrinkage, stable color, qualified strength and acceptable dimensional accuracy.
Yog tias qhov kub thiab txias qis dhau, lub cib yuav raug rho tawm hauv qab -. Yog tias qhov kub thiab txias dhau lawm, lub cib yuav deform, dhau - hlawv lossis poob qhov tseeb. Cov txheej txheem zoo tshaj plaws tsis yog qhov kub siab tshaj plaws, tab sis qhov kub thiab txias tshaj plaws rau cov khoom siv raw thiab qib khoom.
Yuav ua li cas cov neeg yuav khoom yuav tsum ntsuas siab -Alumina Bricks
Thaum yuav khoom siab -alumina cib, cov neeg yuav khoom yuav tsum tsis txhob nug cov duab lossis txiav txim cov khoom los ntawm xim. Cov ntaub ntawv txuj ci tseem ceeb dua. Key indicators include Al2O3 content, bulk density, apparent porosity, cold crushing strength, refractoriness under load, thermal shock resistance and linear change after reheating.
Rau kev tsim kho phab ntsa ntawm lub cub tawg, cov neeg yuav khoom yuav tsom mus rau qhov tseeb qhov tseeb, qhov pom thiab lub zog yooj yim. Rau kev ua hauj lwm hauv ob sab phlu, rotary kilns, kub zones thiab siab -qhov chaw hnav, cov neeg yuav khoom yuav tsum tau muaj kev ruaj ntseg ntawm lub cev thiab tshuaj.
Nws kuj tseem yuav pab tau los qhia rau tus neeg muag khoom ntawm lub cub tawg, ua haujlwm kub, hom roj, txoj haujlwm hauv ob sab phlu, cua thiab seb puas muaj kev cuam tshuam los yog tshuaj lom neeg corrosion. Qhov no tso cai rau tus neeg muag khoom pom zoo rau qib tsim nyog es tsis txhob muab cov cib dav dav xwb
Sintering kub muaj qhov cuam tshuam ncaj qha rau qhov pom, qauv thiab kev pabcuam kev ua haujlwm ntawm siab -alumina cib. Tsawg- kub sintered cib yuav zoo li huv si thiab sib dua ntawm cov xim, tab sis lawv tuaj yeem muaj kev sib txuas tsis tiav thiab muaj kev pheej hmoo siab ntawm kev nthuav dav ntxiv. Kev siab zoo -kub sintering yuav ua rau lub cib xim tsaus, tab sis nws txhim kho qhov ntom ntom, ruaj khov thiab kev pabcuam lub neej.
Rau cov neeg yuav khoom lag luam, qhov zoo tshaj plaws siab -alumina cib tsis yog ib txwm muaj qhov zoo nkauj tshaj plaws. Nws yog lub cib uas phim lub qhov cub ua haujlwm thiab ua tau zoo thaum lub sijhawm ua haujlwm ntev -. Kev ntsuas qhov sib npaug ntawm cov tsos, cov ntaub ntawv kev siv tshuab thiab cov ntawv thov yuav tsum yog txoj hauv kev zoo tshaj plaws los xaiv cov khoom siv refractory zoo.
