2022 nyowani chrome corundum zvidhinha

Zvigadzirwa zvigadzirwa: yakaderera porosity, yakakwira density, yakakwira simba, yakanaka yakakwira tembiricha yekupfeka kuramba, yakanaka kudzivirira kutonhora kwakanyanya uye kupisa kwakanyanya, yakanaka slag kuramba, uye kugadzikana kwakanaka.

chigadzirwa tsanangudzo

Chromium corundum Refractory zvidhinha zvakagadzirwa kubva kune yakachena Al2O3 uye Cr2O3 sezvakakosha zvigadzirwa. Inofananidzwa neiyo yakachena corundum zvidhinha, ine zvirinani zvivakwa, senge Refractoriness, kupfavisa deformation tembiricha pasi pemutoro, simba rinoshanduka, yakanyanya tembiricha inokwira, yakanyanya tembiricha vhoriyamu kugadzikana Kuramba uye slag ngura kuramba.

Chrome corundum zvidhinha ndiwo corundum anodzora zvidhinha zvine Cr2O3. Pakutonhora kwakanyanya, Cr2O3 uye Al2O3 vanogadzira inoenderera yakasimba mhinduro. Naizvozvo, iko kupisa kwepamusoro kuita kwechromium corundum zvidhinha kuri nani pane yakachena corundum zvidhinha. Iyo chromium corundum zvidhinha zvinoshandiswa mugesi yekutsva yeiyo petrochemical indasitiri inofanirwa kunge iri yakaderera silicon, yakaderera simbi, yakaderera alkali, yakachena kuchena, asi zvakare iine huwandu hwakanyanya uye simba. Chrome corundum zvidhinha zvinoshandiswa zvakanyanya, uye zvirimo zveCr2O3 zvakanyanya zviri munzvimbo ye9% kusvika 15%.

chrome corundum zvidhinha zvinodaidzwawo zvepamusoro kupfeka-chiraomi chromium corundum kubata chiteshi zvidhinha. Icho chigadzirwa chepamusoro-soro chakasimudzirwa mumusika mumakore achangopfuura. Inogadzirwa kubva kune yakachena alumina Al2O3 uye chromium oxide Cr2O3 sezvakakosha zvigadzirwa. Inofananidzwa neiyo yakachena corundum zvidhinha, ine zvirinani zvivakwa, senge Refractoriness, mutoro softening tembiricha, Flexural simba, yakakwira tembiricha inokambaira, yakanyanya tembiricha vhoriyamu kudzikama uye slag ngura kuramba. Chrome corundum zvidhinha imhando yepamusoro-giredhi refractory zvinhu, uye hupenyu hwayo hwebasa hunogona kusvika gumi kusvika kumwedzi gumi nesere mushure mevazhinji vanoshandisa mamiririri.

Kudzidzira kwakaratidza kuti iko kushandiswa kwepamusoro kusapfeka chromium corundum yekukata chiteshi zvidhinha mune yekukorobha chiteshi cheiyo inotenderera tembiricha yekupisa hombe-chikamu mabheti, kukwirana kwakakwira pachikamu cheyuniti uye chakakwira kuburitsa, kwete chete zvinogona zvakanyanya kuwedzera hupenyu hwebasa. kubaya chiteshi uye kudzikisa kuvharisa nguva yevira, kuwedzera kugadzirwa, kudzikisira kushandiswa kwekushandisa uye kugadzirisa mitengo, uye kudzikamisa huwandu hwekukurumidza kutonhora uye kudziyisa kunokonzerwa nekudzima kwechoto chekuchengetedza, kuitira kuti hupenyu hwese hwevira rivandudzike, uye pachena hupfumi hunogona kuwanikwa.
