Kukamurwa kwezvidhinha zvinofema (3)

(Mufananidzo) GW akatevedzana slit type inofema zvidhinha

Zvidhinha zvinogoneka zvinogona kukamurwa kuita corundum-spinel system ventilation zvidhinha, corundum-chromium oxide system ventilation zvidhinha, corundum-spinel system ventilation chigaro zvidhinha uye corundum-chromium oxide system kufefetera chigaro zvidhinha zvinoenderana nemidziyo yavo.

1 Corundum-spinel system chidhinha chinofema

Nekuti iyo slag kuramba uye kupisa kutyisa kupikisa kwe-single-phase corundum castables haina kunaka, iyo spinel zvinhu zvine yakanaka slag erosion resistance. Nokudaro, high-purity fused spinel inowedzerwa kune corundum castable kuti iwane chinangwa chekuvandudza kushanda kwecorundum castable. Iyo mbishi inonyanya kuumbwa neplate-shaped corundum, uye zvidhinha zvinopinda nemhepo zvinopfurwa pakupisa kwepamusoro nebinder zvine good thermal shock resistance uye slag resistance.

2 Corundum-Chromium Oxide System Inofema Zvidhinha

Kuti uwedzere kuvandudza kushorwa kwesimbi slag corrosion yemhepo-inopindika zvidhinha, imwe huwandu hwechromium oxide micropowder inowedzerwa kune iyo kuumbwa. Iyo huru yakabikwa iplate-shaped corundum, uye chromium oxide inowedzerwa kune iyo corundum inokandwa. Pakupisa kwepamusoro, chromium oxide uye aluminium oxide inogadzira yakakwirira-yekushisa yakasimba mhinduro, uye panguva imwechete inoumba chikamu chakasimba chekugadzirisa MgO · Cr2O3-MgO · Al2O3 ine zvishoma zve magnesium oxide. Iyo viscosity yeiyi mhinduro yakasimba yakakwirira kwazvo, uye kusvibiswa uye kushorwa kweFe2O3 kana slag kunowedzera zvakanyanya, kuitira kuti kupinda uye kuparara kwesimbi slag kunogona kudzivirirwa zvinobudirira pakupisa kwakanyanya. Panguva imwecheteyo, chikamu chiduku cheCr2O3 chinogonawo kudzivisa kukura kwakanyanya kweAl2O3, kuderedza kushushikana mukristini, uye kugadzirisa zvinhu zvemuviri zvezvinhu. Zvisinei, kana kuwanda kwekuwedzera kwakanyanya, kukura kwezviyo zve corundum kuchave kwakadziviswa zvakanyanya, uye kushushikana kwemukati kuchagadzirwawo, nokudaro kuderedza zvinhu zvemuviri zvezvinhu. Pamusoro pezvo, mutengo weCr2O3 wakakwira zvakanyanya, kuwedzera zvakanyanya kuchawedzera mutengo, uye kuchava nekukanganisa nharaunda.

3 Corundum-spinel system inofema chigaro zvidhinha

Iyo corundum-spinel system inofema chigaro zvidhinha ndiyo inonyanya kushandiswa zvinhu, uye chikuru mbishi zvinhu corundum. Zvakanakira ndezvokuti spinel ine kurwisa kwakasimba kune acids uye alkalis, uye inzvimbo yakakwira yekunyungudika nekuita kwakanaka. Iyo aluminium-magnesium spinel ine yakasimba kuramba kune alkaline slag, uye ine yakagadzikana mhedzisiro pane iron oxides. Apo inosvika pakusangana nemagnetite pakupisa kwepamusoro, ichaita kuti iite sarudzo yakasimba, uye iyo yakakwirira-yepamusoro-yekupisa corrosion resistance yechigaro chinofema chidhinha chinogona kuvandudzwa; Panguva imwecheteyo, mhinduro yakasimba MgO kana Al2O3 spinel ine zvirinani kupisa kwekutya kusagadzikana nekuda kwemutsauko wekuwedzera coefficient pakati pemaminerari.

4 Corundum-Chromium Oxide System Breathable Block

Iyo corundum-chromium oxide system inofema chigaro zvidhinha inogadzirwa pahwaro hweiyo corundum-spinel system kuitira kuti ivandudze kupisa kwepamusoro kwechidhinha chechigaro chinofema. Iyo huru mbishi zvinhu ndeye tabular corundum, uye shoma shoma yeindasitiri chromium oxide poda inowedzerwa. Zvakanakira ndezvokuti pamusana pekuvandudza kushanda kwezvidhinha ne spinel, mhinduro yakasimba yakaumbwa neAl2O3-Cr2O3 ine kuwedzera kukuru kwekudzivirira kwehutu kune iron oxide slag. Kuwedzera zvishoma Cr2O3 kunogona kutadzisa kukura kwakanyanya kwealumina crystals, nokudaro kuderedza makristasi emukati. Kushushikana, kunatsiridza kupisa kwekuvhundutsa kuramba, kunyura kwevhu uye kuramba kwekukurwa kwechigaro chinofema chidhinha.

Mashoko okupedzisa

Hazvina mhosva kuti mamiriro ekushandiswa kwepa-saiti akaoma sei, kuburikidza neruzivo rwekare rwekushandisa uye pa-saiti yekuongorora ongororo, isu zvirokwazvo tichakwanisa kuwana rudzi rwechidhinha chinofema chinosangana nezvinodiwa zvepa-site yekunyungudutsa.
