Malangizo Ogwiritsira Ntchito Silicon Carbide Crucibles

Graphite Crucible

Kugwiritsa ntchito moyenera ndi kukonzazitsulo za silicon carbidezimagwira ntchito yofunika kwambiri pa moyo wawo wautali komanso wogwira mtima. Nawa njira zolimbikitsira kukhazikitsa, kutenthetsa, kulipiritsa, kuchotsa slag, ndi kukonza pambuyo pakugwiritsa ntchito ma crucibles.

Kuyika kwa Crucible:

Musanakhazikitse, yang'anani ng'anjoyo ndikuwongolera zovuta zilizonse zamapangidwe.

Chotsani zotsalira zilizonse kuchokera pamakoma a ng'anjo ndi pansi.

Onetsetsani kuti mabowo otayira akugwira ntchito moyenera ndikuchotsa zotsekereza zilizonse.

Chotsani chowotchera ndikutsimikizira kuti chili cholondola.

Macheke onse omwe ali pamwambawa akatha, ikani crucible pakati pa ng'anjo yamoto, kuti pakhale kusiyana kwa 2 mpaka 3-inch pakati pa crucible ndi makoma a ng'anjo. Zomwe zili pansi ziyenera kukhala zofanana ndi crucible material.

Lawi lamoto liyenera kukhudza crucible yomwe ili pamtunda ndi maziko.

Crucible Preheating: Preheating ndikofunikira kuti muwonjezere moyo wa crucible. Nthawi zambiri kuwonongeka kwa crucible kumachitika panthawi ya preheating, zomwe sizingawonekere mpaka kusungunuka kwachitsulo kumayamba. Tsatirani izi kuti mutenthetse bwino:

Kwa crucibles zatsopano, pang'onopang'ono onjezerani kutentha ndi 100-150 madigiri Celsius pa ola mpaka kufika pafupifupi 200 ° C. Sungani kutentha kumeneku kwa mphindi 30, kenaka kwezani pang'onopang'ono mpaka 500 ° C kuti muchotse chinyezi chilichonse.

Pambuyo pake, tenthetsani crucible ku 800-900 ° C mwachangu momwe mungathere ndikutsitsa kutentha kwa ntchito.

Kutentha kwa crucible kukafika pamalo ogwirira ntchito, onjezerani zouma zouma ku crucible.

Kulipiritsa Crucible: Njira zolipirira zoyenera zimathandizira kuti crucible ikhale ndi moyo wautali. Pewani kuyika zitsulo zoziziritsa kukhosi mopingasa kapena kuziponya mu crucible nthawi iliyonse. Tsatirani malangizo awa pakulipiritsa:

Yanikani zitsulo zachitsulo ndi zigawo zazikulu musanaziwonjeze ku crucible.

Ikani zinthu zachitsulo momasuka mu crucible, kuyambira ndi tiziduswa tating'onoting'ono ngati khushoni ndikuwonjezera timagulu tating'onoting'ono.

Pewani kuwonjezera zitsulo zazikulu pazitsulo zazing'ono zamadzimadzi, chifukwa zingayambitse kuzirala mofulumira, zomwe zimapangitsa kuti zitsulo zikhale zolimba komanso kusweka.

Tsukani zitsulo zonse zamadzimadzi musanazimitse kapena panthawi yopuma, chifukwa ma coefficients osiyana a crucible ndi zitsulo angayambitse kusweka pamene mukuwotcha.

Pitirizani zitsulo zosungunuka muzitsulo zosachepera 4 masentimita pansi kuti muteteze kusefukira.

Kuchotsa Slag:

Onjezani ochotsa slag mwachindunji ku chitsulo chosungunula ndipo pewani kuwalowetsa mu crucible yopanda kanthu kapena kuwasakaniza ndi chitsulo chachitsulo.

Limbikitsani zitsulo zosungunula kuti zitsimikizire ngakhale kugawidwa kwa ochotsa slag ndikuwalepheretsa kuchitapo kanthu ndi makoma a crucible, chifukwa izi zingayambitse dzimbiri ndi kuwonongeka.

Tsukani makoma amkati amkati kumapeto kwa tsiku lililonse la ntchito.

Kukonzekera Pambuyo Pogwiritsira Ntchito Crucible:

Chotsani zitsulo zosungunuka mu crucible musanatseke ng'anjo.

Ngakhale ng'anjo ikadali yotentha, gwiritsani ntchito zida zoyenera kuti muchotse slag iliyonse yomwe imamatira pamakoma opindika, kusamala kuti musawononge crucible.

Sungani mabowo otuluka otsekedwa ndi oyera.

Lolani kuti crucible izizire mwachibadwa mpaka kutentha kwa chipinda.

Kwa zitsulo zomwe zimagwiritsidwa ntchito nthawi zina, zisungeni pamalo owuma komanso otetezedwa momwe sizingasokonezedwe.

Gwirani ma crucibles mofatsa kuti musasweke.

Pewani kuwonetsa crucible mu mpweya mutangotentha, chifukwa izi zingayambitse
