Yintoni na ukhamba isitena esingenakuze siphefumle

Izitena zomoya ezinokungena emoyeni ziyimveliso entsha enobomi obude, ukonga umbane kunye nokuncitshiswa kokusetyenziswa, uyilo olufanelekileyo, ukuzinza kobushushu, ukumelana nokhukuliseko, kunye nokumelana nokuqina, inqanaba lokuvuthwa okuphezulu, ukusebenza okukhuselekileyo nokuthembekileyo, kwaye inkonzo ende yobomi Yima umzuzu. Ikakhulu kusetyenziswa ukhamba wentsimbi-ukwenza, isiseko kunye nezinye iindawo.

Ukuphuhliswa kunye nokusetyenziswa kwe-corundum-spinel ladle izitena eziphefumlayo ngeladi enkulu esulungekisiweyo: Ukuze kuhlangatyezwane neemfuno zesikali esikhulu esicocekileyo selitena lesitena esinokuphefumla, ngeendlela zobuchwephesha ezinje ngokusebenziseka kwefomyula kunye nokudubula kobushushu obuphezulu, ukusebenza kunye nokusetyenziswa kweziphumo kuphuhliswe ngempumelelo. Isitena se-corundum-spinel esinesitena esiphefumlayo kwisitena sendabuko i-chromium corundum isitena esiphefumlayo. Isitena se-ladle sokuphefumla senziwe ngeplate corundum njengezinto ezinamatye amakhulu, ifakelwe i-corundum emhlophe njengempuphu ecolekileyo, yongeza i-6% ye-calcium aluminate cement, i-5% esebenzayo ye-α-Al2O3 micropowder kunye ne-8% spinel, kunye nexabiso elifanelekileyo le-chromium oxide kunye nokunciphisa amanzi Iarhente, emva kosuku lokungcangcazela, ukomisa, ulondolozo lobushushu kwi-1630 ° C ngaphezulu kweeyure ezingama-3. Izitena ezivumayo ukungenisa umoya zisebenza kwiladi enkulu ephucukileyo ukufumana ukusetyenziswa kweziqhamo ngendlela eyanelisayo.

I-ladle engezantsi ye-ladon evuthela i-ladle ye-air-permeable izitena isebenzisa izinto ezihlambulukileyo ezi-homogenized, i-matrix i-co-co-co-milled and mixed, kwaye ezinye izinto eziluhlaza zithunyelwa ngokuthe ngqo ngaphandle, ukwabiwa ngokufanelekileyo, kunye nemveliso elawulwa ngokungqongqo neemfuno zeteknoloji ezihambele phambili zamanye amazwe. Imveliso inezibonelelo zamandla aphezulu, ukumelana nokhukuliseko, ukumelana nokhukuliseko, ukumelana nokungena, kunye nobomi benkonzo ende.

■ Izalathisi eziphambili zomzimba kunye neekhemikhali zemveliso: Al2O3% -95.0 Cr2O3% ≥3.0, porosity ebonakalayo:% ≤16.0, ubuninzi density: g / cm3 -3.20, ubushushu obuqhelekileyo bokucinezelwa kwamandla: MPa 110 ° C -60.0, 1500 ° C ≥100.0, 1600 ° C ≥120.0. Ubushushu obuphezulu bokuqina okuguqukayo: MPa 1400 ° C, 30min ≥10.0.

■ Sebenzisa inxenye: ukubetha ezantsi kweleli.

■ Indlela yokwakha: thambisa udaka lomlilo ngokulinganayo ngaphezulu, kwaye ufakelo luzinzile.
