Kuronga uye nzira dzekugadzira dze lightweight refractories

Muchinyorwa chino, Henan refractory zvidhinha vagadziri vanoda kutaura newe nezve kupatsanurwa uye nzira dzekugadzira dze lightweight refractories. Lightweight refractories inoreva refractories ine yakakwira porosity, yakaderera yakawanda density uye yakaderera thermal conductivity. Marefractories akareruka ane porous dhizaini (iyo porosity inowanzo 40-85%) uye yakanyanya kupisa kupisa.

Pane nzira dzakawanda dzekupatsanura lightweight refractories

1. Inorongwa nehuwandu hwehuwandu. Zvidhinha zvisingaremi zvine huwandu hwakawanda hwe 0.4 ~ 1.3g/cm~2 uye zvidhinha zvinopenya zvine huzhinji husingasviki 0.4g/cm~2.

2. Yakarongerwa nekushanda tembiricha. Kushandisa tembiricha 600～900℃ yakaderera tembiricha insulation zvinhu; 900～1200℃ ndeyepakati tembiricha insulation zvinhu; pamusoro pe1200 ℃ ndeyepamusoro tembiricha yekudzivirira zvinhu.

3. Yakarongedzwa nechimiro chechigadzirwa. Imwe inoumbwa zvidhinha zvisingaremi, zvinosanganisira ivhu, yakakwirira alumina, silica uye zvimwe zvidhinha zvakachena oxide; imwe yacho haina kuumbwa lightweight refractory zvinhu, senge lightweight refractory kongiri.

Iko kurasikirwa kwekuchengetedza kupisa uye kurasikirwa kwekupisa kupisa pamusoro peiyo indasitiri honi yemuviri inowanzoita 24 kusvika 45% yemafuta ekushandisa. Kushandiswa kwezvidhinha zvisingaremi zvine low thermal conductivity uye diki yekupisa simba sechinhu chechimiro chemuviri wechoto chinogona kuchengetedza kushandiswa kwemafuta; panguva imwe chete, nekuda kwechoto Inogona kupisa uye kutonhodzwa nekukurumidza, inovandudza kugadzirwa kwemidziyo, inoderedza huremu hwechoto chevira, inorerutsa chimiro chemoto wemoto, inovandudza chigadzirwa chemhando, inoderedza kudziya kwezvakatipoteredza. , uye inovandudza mamiriro ekushanda.

Izvo zvisingabatsiri zve lightweight refractories yakakura porosity, yakasununguka chimiro uye kushomeka kwe slag kuramba. Iyo slag inokurumidza kupinda mumapores ezvidhinha, zvichiita kuti iparadze, uye haigoni kushandiswa zvakananga pakusangana neslag yakanyungudutswa uye simbi yemvura; ine simba rakaderera remagetsi, kushomeka kwekusagadzikana kwekusagadzikana, uye kusagadzikana kwekupisa kwekupisa. Iyo haigone kushandiswa kune inotakura mitoro zvivakwa, uye haigone kushandiswa kusangana nezvinhu zvechoto uye kupfeka kwakanyanya. Zvesaiti.

Nekuda kwekushomeka kwataurwa pamusoro kwezviyeremekedzo zvehuremu, zvikamu zvemaindasitiri emoto zvinosangana nechaji, mhepo inopisa inotakura slag, kuyerera kukuru, uye zvikamu zvine yakakwira mechanic vibration hazviwanzo kushandiswa. Marefractories akareruka anowanzo shandiswa sekuchengetedza kupisa kana zvinhu zvekuchengetedza kupisa kwemoto.
