Qhov zoo ntawmav nplaum refractory bricksmuaj feem xyuam rau cov txheej txheem xws li raw khoom, txheej txheem piv, xaiv, shaping, ziab thiab sintering. Kev ua haujlwm tsis raug ntawm txhua qhov txuas yuav cuam tshuam rau qhov zoo ntawm cov khoom.
1. Pib nrog kev yuav khoom raw
Ua ntej tshaj plaws, pib los ntawm kev yuav cov khoom siv raw, peb yuav tsum tswj xyuas qhov zoo thiab xav txog cov ntsiab lus txhuas, impurities, thiab cov teeb meem ceev. Vim cov av nplaum uas muaj cov ntsiab lus siab aluminium muaj siab refractoriness, impurities yuav txo cov refractoriness thiab tseem yuav ua rau av nplaum cib kom muaj qhov chaw ntawm qhov tsua. Av nplaum uas nyuaj rau sinter muaj lub zog tsawg thiab siab porosity.
2. Ua tib zoo saib rau tus txheej txheem piv thaum lub sijhawm tsim khoom
Thaum lub sij hawm tsim cov txheej txheem, yuav tsum tau them nyiaj mloog mus rau tus txheej txheem piv. Cov muaj pes tsawg leeg ntawm cov khoom muaj kev sib raug zoo nrog lub zog thiab ntom ntawm av nplaum cib. High-quality av nplaum refractory cib tuaj yeem tsim nrog kev sib xyaw tsim nyog ntawm cov khoom loj, nruab nrab thiab me me. Thaum lub sij hawm sib tov, cov khoom siv raw yuav tsum tau granulated ua ntej thiab tom qab ntawd hmoov. Do li 3 feeb ua ntej ntxiv dej. Tom qab ntxiv dej, lub sijhawm stirring yuav tsum tsis pub tsawg tshaj 10 feeb. Txwv tsis pub, qhov ceev ntawm av nplaum cib tom qab ntau lawm yuav tsawg thiab cov kab nrib pleb yuav tshwm sim.
3. Ua tib zoo saib xyuas qhov chaw ntawm cov pwm thaum lub sij hawm molding txheej txheem
Tsis tas li ntawd, thaum lub sij hawm molding txheej txheem, xyuam xim rau qhov chaw ntawm cov pwm los tiv thaiv burrs, pwm laus los yog rauj tub sab thaum molding. Nws yuav tsum tau molded los ntawm kev kub siab. Cov av nplaum tsim los ntawm kev kub siab muaj siab ceev thiab lub zog. Txawm li cas los xij, molding rauj yuav tsum tau them sai sai rau qhov tso pa tawm, txwv tsis pub cov kab nrib pleb yuav tshwm sim. Tom qab qhov thib ob rauj, siv rauj hnyav. Ua tib zoo saib xyuas qhov xwm txheej ntawm cov pwm, thiab tsis txhob cia cov pwm mus rau lub hnub nyoog thiab ua rau flash, uas yuav cuam tshuam rau cov tsos ntawm cov av nplaum cib.
Kev tua hluav taws yog qhov kawg ntawm kev ua haujlwm ntawm cov av nplaum refractory cib. Qhov ntau ntawm cov cib yuav tsum tiaj tus, ncaj, thiab ncaj. Thaum thauj lub tawb nqa khoom, qhov sib txawv tsim nyog thiab cov kab hluav taws xob yuav tsum tau tso tseg. Qhov kev ncua deb uas tsim nyog yuav tsum tau khaws cia nruab nrab ntawm cov pob zeb cib thiab cov phab ntsa kiln thiab lub ru tsev. Txo qhov tsis kam ntawm cov foob pob hluav taws hauv qhov cub. Lub tsheb kiln yuav tsum tau ntim densely nyob rau sab saum toj thiab sparsely nyob rau hauv qab kom cia tag nrho thiab txawm tua. Qhov hluav taws kub rau sinter cov av nplaum cib yuav tsum oxidize cov cua, kom cov av nplaum cib yuav muaj xim tib yam thiab tsis nthuav los yog shrinkage.
Yog tias cov ntsiab lus saum toj no tau ua tiav thaum lub sijhawm tsim khoom, qhov zoo ntawm cov av nplaum cib yuav raug txhim kho.
