I. Flow Mechanism thiab Moulding Method
1. Tus kheej-Flowing Castables: ntws thiab deaerated los ntawm lawv tus kheej lub ntiajteb txawj nqus, yuav tsum tsis muaj kev co sab nraud. Lub slurry yog nyob rau hauv lub xeev ncua, nrog rau cov aggregate encapsulated los ntawm ib tug tas mus li theem, exhibiting tag nrho cov "kua" tus cwj pwm.
2. Refractory Castables: Nyob rau hauv kev co molding system. Kev sib txhuam siab ntawm aggregates xav tau kev co sab nraud kom rov kho cov khoom thiab tshem tawm cov npuas npuas; pwm kuj yuav tsum tau ua kom zoo.
II. Aggregate Gradation thiab Morphology
1. Tus kheej-Flowing refractories Castables: Siv ze -sperical, rounded aggregates, nrog kev tswj nruj nruj ntawm 5mm particle loj, qee zaus so rau 8mm. High roundness thiab tsawg nqus dej txo cov kev sib txhuam sab hauv thiab txhim kho rollability.
2. Refractory MAAs Castables: Tsis sib xws aggregate morphology nrog cov npoo ntse; gradation ntau yam 0-10 hli, nrog tshwj xeeb ntau yam tso cai mus txog 25mm. Coarse-cov pob txha pob txha ua rau cov khoom hnyav dua-cov kabmob kub thiab siab- qhov kub thiab txias rau cov ntaub ntawv, tab sis txo cov dej ntws.
III. Matrix Composition thiab Slurry yam ntxwv
1. Tus kheej- ntws Castables: Siab matrix feem; Lub synergistic nyhuv ntawm ultrafine hmoov, dispersant, thiab tshem tawm tus neeg sawv cev muab lub slurry "Bingham kua" yam ntxwv nyob rau hauv ib tug zoo li qub lub xeev, uas tsis tshua muaj nqi yield thiab nruab nrab yas viscosity. Aggregates nyob twj ywm dispersed, tso cai rau tag nrho tus kheej -leveling.
2. Refractory Castables: Tsawg matrix; Kev sib cuag particle feem ntau yog taw tes rau - rau - nto. Kev vibration yog xav tau los rhuav tshem "arch choj" qauv, tsim kom muaj cov ntim ntom ntom. Lub kaw lus yog nyob ntawm ntau lub zog; yog li ntawd, nws chav - kub thiab siab - qhov kub thiab txias cov khoom siv feem ntau yog siab dua li ntawm tus kheej - cov ntaub ntawv ntws ntawm tib yam khoom.
IV. Ntxiv dej thiab kev tswj xyuas kev tsim kho
1. Tus kheej- ntws Castables: Ntau dua dej ntxiv dua li cov tsoos vibratory castables. Cov dej ntau dhau activates cov dispersant, ua rau cov hmoov ultrafine los ua ib tug dual nyhuv ntawm filling thiab lubrication, ntxiv txo tus nqi yield; Txawm li cas los xij, siab - dej ua tau zoo- txo cov neeg ua hauj lwm thiab cov chaw tswj xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cais.
2. Cov khoom siv Refractory Castables: Cov dej ntxiv yuav tsum tau tswj nruj me ntsis. Cov dej ntau dhau yuav ua rau cov khoom sib cais thiab los ntshav thaum lub sij hawm vibration, tawm hauv cov pores tom qab ci, txo lub zog thiab corrosion kuj.
V. Pwm thiab ib puag ncig ua haujlwm
1. Tus kheej- ntws refractory Castables: Tsis xav tau kev txhawb nqa nyuaj; Tsuas yog cov baffles yooj yim lossis cov qauv ntawv yog xav tau. Tso dej los yog tus kheej - ntws nozzles tuaj yeem siv los sau cov chaw siab lossis nqaim, txo kev siv zog thiab siv sijhawm ua haujlwm.
2. Refractory Castables: Tag nrho- cov pwm loj yuav tsum tau ua raws li lub tshuab hluav taws xob lub plhaub zoo li qub, thiab cov pwm yuav tsum muaj qhov nruj txaus los tiv thaiv lub siab ntawm kev co. Demolding lub sij hawm thiab turnover efficiency ncaj qha cuam tshuam rau lub voj voog kev tsim kho.
VI. Daim ntawv thov cheeb tsam thiab Thickness yuav tsum tau
1. Tus kheej- ntws Castables: Haum rau nyias - phab ntsa hauv ob sab phlu (<100mm), geometrically complex or manually vibratory dead corners, local repairs, and emergency repairs requiring rapid furnace drying.
2. Refractory cement Castables: Siv nyob rau hauv loj - cheeb tsam load- bearing cheeb tsam ntawm cov txheej txheem ua hauj lwm, feem ntau tsim nrog ib tug thickness ntau tshaj los yog sib npaug zos rau 100mm. Cov qauv tuab tiv taus slag yaig thiab thermomechanical kev nyuaj siab, ua kom muaj kev ua haujlwm ntev -.
VII. Material Expansion thiab Development Trends
Tus kheej- ntws castables tsis yog ib qho - ntau lub tswv yim, tab sis tuaj yeem ua tiav "tus kheej- ntws" tsim ntawm ntau yam matrices xws li siab- alumina, corundum- spinel, magnesia, thiab silicon carbide. Los ntawm kev kho cov dispersion - ncua kev kawm ntawv -thixotropic ternary system, lawv muaj peev xwm ua tau raws li cov kev cai sib txawv rau purity, erosion resistance, thiab thermal shock resistance nyob rau hauv txawv cua sov cua (oxidation, txo, nqus).
Nrog kev nce ntawm kev tsim kho tshiab xws li kev siv, txau, thiab 3D luam ntawv, tus kheej- cov ntaub ntawv ntws tau dhau los ua ib ceg tseem ceeb ntawm qis- ua haujlwm, siab- ua haujlwm tau zoo, thiab cov ntaub ntawv ntsuab refractory, thaum cov tsoos vibratory castables txuas ntxiv tuav txoj haujlwm tsis tuaj yeem nyob rau hauv tuab - txheej, siab{5}} Ob qho tib si ntxiv rau ib leeg, sib koom ua ke ntawm kev txhim kho ntawm kiln hauv ob sab phlu thev naus laus zis mus rau "kev ua haujlwm zoning thiab kev sib txuam.
