Fused Magnesia

Fused Magnesia Description

Fused magnesia (MgO) feem ntau yog tsim los ntawm hluav taws xob arc melting ntawm caustic calcined magnesia, tuag burned magnesia los yog raw magnesite nyob rau hauv lub cub tawg ntawm kub tshaj 2750 degree, ua ib tug refractory khoom uas hloov crystalline qauv yog xws li hais tias nws cov yam ntxwv thiab kev ua tau zoo. superior rau cov khoom sib tw.

Fused magnesia yog superior rau tuag hlawv magnesia nyob rau hauv lub zog, abrasion kuj thiab tshuaj stability. Cov ntawv thov loj yog nyob rau hauv refractory thiab hluav taws xob insulating kev lag luam. Fused magnesia cov ntaub ntawv feem ntau poob rau hauv ib qho ntawm ob pawg uas yog qib refractory thiab qib hluav taws xob.

Qib Refractory:

Qhov sib ntxiv ntawm fused magnesia nplej tuaj yeem txhim kho qhov kev ua tau zoo thiab ua haujlwm ntev ntawm cov refractories yooj yim xws li magcarbon cib. Qhov no yog ib qho kev ua haujlwm ntawm ntau dua qhov tshwj xeeb lub ntiajteb txawj nqus thiab loj periclase siv lead ua loj, ntxiv rau kev hloov kho ntawm cov khoom siv silicates. Refractory qib fused magnesia muaj cov ntsiab lus tshwj xeeb thiab feem ntau yog tus cwj pwm los ntawm cov hauv qab no.

● Feem ntau cov ntsiab lus magnesia siab (tsawg kawg 96 feem pua ​​​​MgO thiab mus txog / tshaj 99 feem pua ​​MgO)

● Tsawg silica; txiv qaub: silica ratio ntawm 2: 1

● Qhov ntom ntawm 3.50 g / cm3 lossis ntau dua

● Large periclase crystal sizes (>1000 microns)

Vim nws cov corrosion kuj zoo heev, qib refractory fused magnesia yog siv nyob rau hauv siab coj qhov chaw nyob rau hauv steel ua, piv txwv li, yooj yim oxygen thiab hluav taws xob arc furnaces, converters thiab ladles.

Ultra high purity (>99 feem pua ​​​​MgO) cov qhab nia tau siv rau hauv cov ntawv siv thev naus laus zis xws li cov khoom siv kho qhov muag, cov tshuab hluav taws xob nuclear thiab foob pob hluav taws.

Hluav taws xob qib:

Fused magnesia kuj tseem siv los ua cov khoom siv hluav taws xob hauv cov khoom cua sov. Txawm hais tias cov qib hluav taws xob ntawm fused magnesia muaj cov ntsiab lus nruj heev, lawv tsis tas yuav tsum muaj MgO cov ntsiab lus siab tshaj plaws lossis qhov ntom ntom. Cov impurities xws li sulfur thiab hlau yog tshwj xeeb tshaj yog undesirable, tab sis cov khoom yuav tsum muaj silica txaus los txhim kho nws cov khoom hluav taws xob. Cov hauv qab no yog cov yam ntxwv ntawm qib hluav taws xob fused magnesia.

● Qib qis ntawm boron, sulfur, hlau thiab kab kawm.

● Txiv qaub: silica ratios ntawm 1: 2 (piv txwv li refractory yuav tsum).

● Siv los ua cov khoom siv hluav taws xob insulating hauv ceramic sheaths rau cov khoom cua sov.

SSC tsim peb pawg ntawm fused magnesia, txhua qhov cuam tshuam rau ib puag ncig ntawm daim ntawv thov.

● Kub kub (txog thiab tshaj 950 degree) yuav tsum muaj siab purity fused magnesia ntawm 94-97 ib xees MgO thiab tsawg silica thiab calcium cov ntsiab lus, piv txwv li, rau qhov cub grills.

● Nruab nrab kub (txog 800 degree) nrog cov ntsiab lus magnesia ntawm 93-96 ib xees MgO, piv txwv li, rau cov khoom hauv qhov cub.

● Tsawg Kub (<600°c) with=""><90 per="" cent="" mgo,="" eg,="" immersion="">

Hluav taws xob qib cements tuaj yeem tsim los ntawm kev sib xyaw hluav taws xob qib fused magnesia thiab plasticisers thiab hardeners siv rau hauv cov phaj kub, toasted sandwich makers thiab hluav taws xob hlau. Cov qib hluav taws xob fused magnesia tuaj yeem muab cov txheej txheem silicon rau kev tiv thaiv ntau dua rau cov dej noo noo thaum lub caij cua sov tsim khoom; Qhov no kuj tseem txhim kho cov rwb thaiv tsev txias tsis kam ntawm cov dej num uas tsis tshua muaj kev cuam tshuam rau cov av noo. Hluav taws xob qib magnesia yog kuaj rau nws cov khoom siv hluav taws xob thiab thermal, xws li hluav taws xob tiv taus thiab siab thermal conductivity.
