Khoom Description

Raws li ib qho tseem ceeb ntawm cov khoom siv kho cua sov thiab cov ntaub ntawv refractory, magnesia bricks muaj cov yam ntxwv ntawm cov hluav taws kub tsis kam, siab zog, zoo kub tsis kam thiab stability, thiab thermal expansion coefficient tsawg.

Cov khoom tseem ceeb ntawm magnesia bricks yog magnesium oxide, alumina, alkali hlau oxides, tsis tshua muaj lub ntiaj teb oxides, thiab lwm yam. Lub hardness ntawm 4-6 thiab qhov ceev yog 3-3.2 tons / cubic meter. Lub zog compressive yog nyob nruab nrab ntawm 120-200 MPa, thiab lub zog tensile yog li 80 MPa. Lub refractory kub yog nyob nruab nrab ntawm 1500℃thiab 2000 degree, yog li nws muaj corrosion kuj zoo thiab kub stability nyob rau hauv hnyav ib puag ncig xws li kub, hnyav hnyav thiab muaj zog acid.

Cov kev ceev faj

1. Magnesia bricks yuav tsum tsis txhob hnyav hnyav thiab vibration thaum siv kom tsis txhob tawg, tawg, thiab lwm yam.

2. Ua tib zoo saib xyuas lub sealing thiab noo noo thaum siv cov magnesia cib. Cov dej noo ntau dhau yuav cuam tshuam rau nws qhov kev ua tau zoo thiab txawm tias nws lub neej ua haujlwm.

3. Kev puas tsuaj magnesia bricks yuav tsum tau hloov nyob rau hauv lub sij hawm kom tsis txhob muaj kev cuam tshuam rau kev ua hauj lwm zoo thiab ncua lub neej kev pab cuam.

4. Magnesia bricks yuav tsum ya raws - pov thawj thiab tiv thaiv - kev sib tsoo thaum thauj thiab ntim khoom kom ntseeg tau tias lawv lub cev muaj zog thiab ntom ntom.

Cov khoomQhov zoo

Magnesia bricks muaj qhov zoo tshaj plaws tshav kub. Magnesia bricks yog ua los ntawm siab -purity magnesium oxide thiab lwm yam ntaub ntawv. Lawv cov khoom siv yog tuab thiab tsis raug rau kev puas tsuaj los ntawm qhov kub thiab txias thiab thermal shock. Yog li ntawd, magnesia bricks tuaj yeem tiv taus qhov kub thiab txias mus txog 2000℃thiab yog qhov zoo tshaj plaws siab tshaj -cov khoom kub refractory.

Magnesia bricks muaj corrosion kuj zoo. Nyob rau hauv qee qhov tshwj xeeb siab - qhov kub thiab txias tshaj tawm, cov khoom siv refractory tej zaum yuav corroded thiab puas, tab sis magnesia bricks tuaj yeem ua haujlwm nyob rau hauv ib puag ncig hnyav rau lub sijhawm ntev yam tsis muaj corroded, yog li ua kom muaj kev txuas ntxiv ntawm cov txheej txheem ntau lawm. thiab stability.

Magnesia bricks kuj muaj siab compressive zog thiab tensile zog. Qhov no txhais tau hais tias txawm tias nws raug rau qee qhov kev quab yuam sab nraud thaum siv, nws tuaj yeem tiv taus cov kev ntxhov siab thiab kev ntxhov siab zoo thiab yuav tsis tawg lossis deform vim yog sab nraud quab yuam.

Magnesia bricks muaj thermal conductivity zoo. Qhov no yog vim magnesium muaj thermal conductivity zoo thiab tuaj yeem nqus tau, coj thiab tso tawm thermal zog zoo. Yog li ntawd, nyob rau hauv siab - qhov kub thiab txias ib puag ncig, kev siv cov magnesia cib tuaj yeem hloov pauv tau zoo thiab ua kom cov cua sov, yog li ua kom muaj kev ruaj ntseg thiab sib npaug ntawm qhov kub siab - ib puag ncig.
