Uyini isitini esidonsa umoya

Isitayela se-ladle esivuleka emoyeni ngumkhiqizo omusha onempilo ende, ukonga amandla nokuncishiswa kokusetshenziswa, enokwakheka kwesakhiwo okunengqondo, ukuzinza okuhle kokushisa, ukumelana nokuguguleka, ukumelana nokuguguleka, nokumelana namandla okungena, izinga eliphakeme lokushaya, ukusebenza okuphephile nokwethembekile, futhi impilo ende yokusebenza Linda kancane. Ikakhulu esetshenziswa lensimbi wokwenza steel, base nezinye izingxenye.

Ukuthuthukiswa nokusetshenziswa kwe-corundum-spinel ladle izitini eziphefumula ngentambo enkulu ecwengekile: Ukuze kuhlangatshezwane nezidingo zesikali esikhulu esicocekile sezitini zokuphefumula, ngezindlela zobuchwepheshe ezinjengokusetshenziswa kwefomula nokudubula okushisa okuphezulu, imiphumela yokusebenza nokusetshenziswa kwenziwe ngempumelelo. I-corundum-spinel ladle isitini esiphefumula kahle sesitini sendabuko se-chromium corundum. Isitini esiphefumulwayo se-ladle senziwe nge-plate corundum njengezinto eziyimbudumbudu, ihlanganiswe i-corundum emhlophe njengempuphu ecolekileyo, futhi yengeza u-6% usimende we-calcium aluminate omsulwa, u-5% osebenza nge-microfowder α-Al2O3 no-8% spinel, kanye nenani elifanele le-chromium oxide namanzi anciphisa i-ejenti, ngemuva kokudlidliza kwakheka, ukomiswa, ukulondolozwa kokushisa ku-1630 ° C isikhathi esingaphezu kwamahora ama-3. Isitini esikhipha umoya esivumayo sisetshenziswa elalini elikhulu elicwengiweyo ukuthola Ukusetshenziswa okwanelisayo kwezithelo.

I-ladle bottom argon blower ladle air-permeable brick isebenzisa okuphezulu okumsulwa okwenziwe ngezinto ezi-homogenized, i-matrix ihlanganiswe ngaphambili futhi ixutshwe, futhi ezinye izinto zokusetshenziswa zingeniswa ngqo zivela ngaphandle, ukwabiwa okufanele, nokukhiqizwa okuqinile ngezidingo zomhlaba jikelele zobuchwepheshe. Umkhiqizo unezinzuzo zamandla aphezulu, ukumelana nokuguguleka, ukumelana nokuguguleka, ukumelana nokungena, kanye nempilo ende yokusebenza.

■ Izinkomba eziyinhloko zomzimba nezamakhemikhali zomkhiqizo: Al2O3% ≥95.0 Cr2O3% ≥3.0, porosity ebonakalayo:% ≤16.0, ukuminyana ngobuningi: g / cm3 -3.20, amandla ajwayelekile okushisa okucindezelayo: MPa 110 ° C ≥60.0, 1500 ° C ≥100.0, 1600 ° C ≥120.0. Amandla okushisa aphezulu okuguquguquka: MPa 1400 ° C, 30min ≥10.0.

■ Sebenzisa ingxenye: ukushaya phansi kwekhanda.

■ Indlela yokwakha: gcoba udaka lomlilo ngokulinganayo ebusweni, futhi ukufakwa kuzinzile.
