Munzvimbo yekushanda kwemaindasitiri epamusoro-soro, kudiwa kwezvinhu zvinogara, zvinodzivirira kupisa hazvigone kutaurirana. Kubva pamavira ekugadzira simbi kusvika kumasimbi esimende, zvishandiso zvakafumurwa kune tembiricha yakanyanyisa, kukukurwa kwemakemikari, uye kupfeka kwemuchina zvinoda kuchengetedzwa kwakavimbika kuti ive nechokwadi chekushanda uye hupenyu hurefu. Apa ndipocorundum castableinomira pachena sechinhu chinoshandura mutambo, ichipa kuita kusingaenzaniswi kunoenderana neyakaomesesa zviyero zveindasitiri.
Corundum castable chinhu chinopesana chinoumbwa zvakanyanya ne corundum (aluminium oxide, Al₂O₃) seyakaunganidzwa uye matrix, yakasanganiswa nemhando yepamusoro bhaidhi uye zvinowedzera. Hunhu hwayo hunoshamisa hunobva pahunhu hwemasikirwo ecorundum, iyo inonyungudika inodarika 2000 ° C, yakanakisa kugadzikana kwemafuta, uye hukuru hwemagetsi simba. Kusiyana nechinyakare refractory zvinhu, corundum castable inopa yakasarudzika musanganiswa wekuchinjika uye kusimba-yayo inodururwa inobvumira kuisirwa nyore muchimiro chakaoma uye zvimiro, nepo dense chimiro chinopesana ne spalling, abrasion, uye kurwisa kwemakemikari kubva slags, acids, uye alkalis.
Imwe yemabhenefiti akakosha ecorundum castable ndeyekuita kwayo kwakasiyana-siyana mumaindasitiri. Muindasitiri yesimbi, inoshandiswa zvakanyanya mumaladhi, tundishes, uye blast furnace linings, kwainomira tembiricha yesimbi yakanyungudutswa uye hukasha hwe slag. Vagadziri vesimbi vanovimba necorundum castable kuti ideredze nguva yekudzikira kunokonzerwa nekutadza kwezvinhu, sezvo hupenyu hwayo hurefu hwesevhisi huchishandura kune mashoma ekugadzirisa uye kuderera kwemitengo yekushanda. Kune indasitiri yesimende, corundum inokandwa inoiswa mu simende kiln shanduko yenzvimbo uye tertiary air ducts, inotsungirira kupisa kwakanyanya uye abrasive simende clinker. Kupokana kwayo nekuvhundutsa kwemafuta kunovimbisa kuti zvinhu zvacho zvinoramba zvakamira kunyangwe panguva yekukurumidza kushanduka kwekushisa, dambudziko rinowanzoitika mukugadzira simende.
Kupfuura simbi nesimende, corundum inokandwa inokunda mune isiri-ferrous metallurgy, kugadzira magirazi, uye zvidyarwa zvekupisa tsvina. Mukunyungudusa kusina ferrous (semuenzaniso, mhangura, aruminiyamu), inodzivisa kuparara kubva kune simbi dzakanyungudutswa uye kuyerera, kudzivirira midziyo yakakosha yakadai semavira ekunyungudutsa uye crucibles. Mafekitari egirazi anoshandisa corundum inokandwa mune regenerator uye zviteshi zvechoto, uko inochengetedza kuvimbika kwechimiro pasi pekupisa kwakanyanya uye kuratidzwa kwemakemikari kubva kugirazi rinonyungudika. Zvidyarwa zvekupisa tsvina zvinobatsirikana kubva mukupokana kwayo nemagasi ane muchetura uye kubvongodzwa kwedota, kuwedzera hupenyu hwemaraini ekupisa uye kuderedza njodzi dzenharaunda.
Chimwe chinogombedzera che corundum castable kuita kwayo kwakajairika. Vagadziri vanogona kugadzirisa kuumbwa kwecorundum (semuenzaniso, chena corundum, brown corundum, tabular corundum) uye zvekuwedzera kuti zvienderane nezvinodiwa zvekushandisa. Semuenzaniso, high-alumina corundum castable (Al₂O₃ content ≥ 90%) inopa yakawedzera kupisa kwekudzivirira kune yakanyanya-yakakwirira-tembiricha nharaunda, nepo yakaderera-simende kana ultra-yakaderera-simende maumbirwo anovandudza density uye kuderedza porosity, kuderedza slag kupinda. Pamusoro pezvo, lightweight corundum castable options inopa kupisa kwekushisa pasina kukanganisa simba remuchina, yakanakira madhizaini ekuchengetedza simba emaindasitiri.
Paunenge uchisarudza corundum inokandwa, zvakakosha kuti ubatane nemutengesi ane mukurumbira anoomerera kune epasi rose mhando zviyero (semuenzaniso, ISO, ASTM). Yepamusoro-mhando corundum castable inopinda yakasimba yemhando yekudzora, kuve nechokwadi chekuita kunoenderana, yakagadzikana makemikari kuumbwa, uye yakavimbika yekuisa zvivakwa. Vatengesi vane hunyanzvi hwetekinoroji vanogonawo kupa rutsigiro rwepa-saiti, kusanganisira kutungamira kwekusarudza zvinhu, mirairo yekusanganisa, uye matipi ekugadzirisa ekugadzirisa, kuwedzera kukosha kwekudyara kwako.
Mumamiriro emazuva ano emakwikwi eindasitiri, kuderedza nguva, kudzikisa mari yekugadzirisa, uye kuvandudza kushanda zvakanaka ndizvo zvinonyanya kukosha. Corundum castable inoburitsa pamativi ese, ichipa inodhura-inoshanda, inogara kwenguva refu mhinduro yekukwirira-tembiricha maapplication. Iyo yakasarudzika kupisa kupisa, corrosion resistance, uye kuita zvakasiyana-siyana kunoita kuti ive chinhu chesarudzo kune maindasitiri ari kutsvaga kuwedzera chigadzirwa uye kuvimbika.
Kunyangwe iwe uchishanda chigayo chesimbi, simende chirimwa, fekitori yegirazi, kana nzvimbo yekupisa tsvina, corundum inokandwa inogona kushandura mashandiro ako ekupisa kwepamusoro. Chengetedza mari mumhando yecorundum inokandwa nhasi uye unzwe mutsauko mukuita kwemidziyo, hupenyu hurefu, uye pazasi-mutsara mhedzisiro. Bata timu yedu yenyanzvi dzekuramba kuti udzidze zvakawanda nezve yedu yakagadziridzwa corundum castable mhinduro uye tora danho rekutanga kukwenenzvera maitiro ako emaindasitiri.
