Ndeipi ladle yekufema chidhinha

Ndiro yemhepo-inokwanisika zvidhinha chigadzirwa chitsva chine hupenyu hwakareba, simba rekuchengetedza uye kudzikisira kudyiwa, zvine hunyanzvi dhizaini dhizaini, kugadzikana kwemafuta, kusagadzikana kwekuputika, uye kupokana kwekukwira, kukwirisa-kuburikidza nehuremu, kushanda kwakachengeteka uye kwakavimbika, uye hupenyu hurefu hwebasa Mira zvishoma. Inonyanya kushandiswa mukugadzira simbi, chigadziko uye zvimwe zvikamu.

Kubudirira uye kushandiswa kwekorundum-spinel ladle zvidhinha zvinofema kune yakakura-yakakwenenzverwa ladle: Kuti uwane zvinodikanwa zvehombe-yakanatswa ladle yezvidhinha zvinofema, kuburikidza nehunyanzvi nzira senge fomula optimization uye yakakwira-tembiricha yekupfura, mashandiro uye mashandisiro ekushandisa zvakagadzirwa zvinobudirira. Iyo corundum-spinel ladle inofema dhinha yetsika chromium corundum ladle inofema zvidhina. Iyo ladle yekufema chidhinha chakagadzirwa neplate corundum seye granular zvinhu, yakasanganiswa chena corundum sehupfu hwakatsetseka, uye yakawedzera 6% yakachena calcium aluminate samende, 5% Inoshanda α-Al2O3 micropowder uye 8% spinel, pamwe yakaenzana huwandu hwe chromium oxide uye mvura kudzikisira mumiririri, mushure me vibration achiumba, kuomesa, kuchengetedza kupisa pa1630 ° C kweanopfuura maawa matatu. Iyo ladle mweya-inokwanisika zvidhinha inoshandiswa pane hombe yakanatswa ladle kuwana Kune inogutsa kushandiswa kwemichero.

Iyo ladle yepasi argon ichivhuvhuta ladle mweya-inokwanisika zvidhinha inotora yakakwira-yakachena homogenized mbishi zvigadzirwa, iyo matrix inotangirwa-kubatanidzwa-yakasanganiswa uye yakavhenganiswa, uye zvimwe mbishi zvigadzirwa zvinotengwa zvakananga kubva kunze, kunzwisiswa kugoverwa, uye zvakanyatso kudzorwa kugadzirwa zvinoenderana pamwe nedzimwe nyika dzepamberi tekinoroji zvinodiwa. Chigadzirwa chine zvakanakira simba rakakwira, kudzvinyirira kusagadzikana, kupera kwemhepo, kupindira kwekupinda, uye hupenyu hwakareba hwebasa.

■ Main zviratidzo zvemuviri uye zvemakemikari zvechigadzirwa: Al2O3% -95.0 Cr2O3% -3.0, pachena porosity:% -16.0, hombe density: g / cm3 -3.20, yakajairwa tembiricha inomanikidza simba: MPa 110 ° C -60.0, 1500 ° C ≥100.0, 1600 ° C ≥120.0. Yakakwirira tembiricha inoshanduka simba: MPa 1400 ° C, 30min -10.0.

■ Shandisa chikamu: pasi kurova kwembiru.

■ Maitiro ekuvaka: zora moto matope zvakaenzana pamusoro, uye kumisikidza kwakatsiga.
