Semi Silica Cib

Semi silica cib xa mus rau aluminium-silicon refractory khoom nrog cov ntsiab lus ntawm ntau tshaj 65% thiab cov ntsiab lus ntawm 15% mus rau 30%. Semi-silica cib feem ntau siv cov av nplaum uas muaj quartz impurities los yog haiv neeg kaolin, refractory av nplaum los yog tailings thiab pyrophyllite tau los ntawm kaolin ntxhia ua cov ntaub ntawv raw. Lub refractory degree ntawm semi-silica hluav taws cib yog hais txog SK27 (1610 degree), thiab nws yog cov feem ntau refractory khoom nyob rau hauv cov nqe lus ntawm muaj pes tsawg leeg. Nws cov yam ntxwv suav nrog tus nqi qis, qhov ntim me me hloov pauv ntawm qhov kub thiab txias, thiab zoo tiv thaiv kom txias thiab cua sov sai.

Nruab Nrab Thermal Conductivity: Semi Silica Cib muab kev ntseeg siab thermal kuj, ua rau nws tsim nyog rau cov ntawv thov uas huab cua kub tsis yog thawj qhov kev txhawj xeeb.
Kev Tsim Kho Kev Tsim Nyog: Nws muaj pes tsawg leeg tso cai rau cov txheej txheem tsim khoom siv nyiaj ntau dua, muab kev siv nyiaj txiag zoo dua yam tsis muaj kev cuam tshuam qhov tseem ceeb ntawm cov khoom siv refractory.
Mechanical Strength: Lub cib lub zog muaj peev xwm ua kom muaj kev ruaj khov nyob rau hauv ib puag ncig nrog rau cov neeg kho tshuab kev ntxhov siab, ua rau lub neej ntev kev pab cuam.

Cov txheej txheem ntau lawm ntawm semi silica cib tuaj yeem muab faib ua ob hom: raug rho tawm lossis tsis raug rho tawm haujlwm. Cov cib uas tsis muaj hluav taws xob feem ntau yog ua los ntawm cov iav dej ua tus neeg sawv cev. Kev tsim cov txheej txheem ntawm cov cib raug rho tawm yog kwv yees tib yam li cov khoom pasted, tab sis nws kuj muaj nws tus yam ntxwv, feem ntau xav txog hauv:
(1) Seb puas ntxiv clinker yog txiav txim siab los ntawm cov yam ntxwv ntawm cov khoom siv raw thiab kev siv cov khoom siv. Siliceous av nplaum muaj me me shrinkage thaum lub sij hawm tua thiab siv tau yam tsis ntxiv clinker. Txhawm rau txhim kho lub thermal shock tsis kam ntawm semi-silica cib, 10% mus rau 20% clinker yuav tsum tau ntxiv.
(2) Yog tias muaj ob peb cov khoom fusible thiab coarse quartz hais nyob rau hauv cov khoom siv raw, semi-silica cib yuav muaj qhov ntom ntom thiab tsis muaj zog, tab sis zoo thermal shock kuj thiab siab load softening kub; txwv tsis pub, cov khoom yuav muaj hluav taws tsis zoo thiab thermal shock tsis kam. txo. Yog li ntawd, thaum ntxiv quartz xuab zeb los yog silica clinker, nws yuav tsum tau txiav txim siab raws li kev siv ntawm cov khoom seb puas yuav ua rau kom cov khoom me me los yog ntxiv cov khoom zoo.
(3) Lub ntim shrinkage ntawm semi-silica cib tsis pom tseeb hauv qab 1250 degree. Thaum qhov kub thiab txias, qhov ntim qis heev thaum cov kua theem nce. Yog li ntawd, nws qhov kub hnyiab yuav tsum siab dua li cov av nplaum cib, feem ntau nyob rau hauv thaj tsam ntawm 1350-1410 degree . Tau cov khoom siv high-density.
(4) Thaum siv pyrophyllite ua raw khoom rau semi silica cib, cov txheej txheem yuav tsum tau txiav txim siab raws li cov tshuaj muaj pes tsawg leeg ntawm pyrophyllite raw khoom. Pyrophyllite, qhov tseem ceeb ntawm pyrophyllite, poob qis me ntsis tom qab lub cev qhuav dej thiab tseem tuav nws cov qauv lattice. Yog li ntawd, cib tuaj yeem ua ncaj qha los ntawm cov khoom siv raw, thiab cov khoom siv ntxhia kuj tuaj yeem siv tag nrho los txo cov nqi tsim khoom. Txhawm rau tiv thaiv kev nthuav dav thiab txo lub zog thaum lub sijhawm tua, cov khoom siv pob zeb wax kuj tseem tuaj yeem muab calcined rau hauv clinker, thiab ib feem me me tuaj yeem muab ntxiv rau hauv batching. Nws tseem yuav tsum tau muab sau tseg tias wax pob zeb muaj cov dej tsis zoo, yog li cov dej noo ntawm cov av nkos yuav tsum tau tswj nruj me ntsis, txwv tsis pub cov kab nrib pleb hauv cov khoom tiav yuav tshwm sim thaum molding.

Semi silica cib yog siv los ua cov txheej txheem refractory ntawm ladle linings thiab cam khwb cia hlau tshuab. Nws tseem tuaj yeem siv rau hauv qhov cub kub kub, cov khoom siv hluav taws xob regenerator checker cib, hlau rauv hauv ob sab phlu, ntau qhov cub hauv qab thiab flues, thiab lwm yam.
