Precautions for the operation of coreless ityhini for conventional foundry

The following precautions are well-known to melters and foundries, and are common knowledge not only for coreless induction furnaces but also for all metal smelting operations. This is just for general knowledge and does not involve all types of operations. These matters should be explained clearly and appropriately expanded or perfected by a specific operator.

Imisebenzi yokunyibilikisa kunye nokuphosa kufuneka iphelele kubasebenzi abanezatifikethi zemfundo, okanye abasebenzi abaqeqeshiweyo kuqeqesho lwefektri kunye novavanyo, okanye imisebenzi phantsi komyalelo wobunjineli abaqeqeshiweyo kunye nabasebenzi bobugcisa kumzi-mveliso.

Abasebenzi abakwisiza kufuneka bahlale benxibe iiglasi zokhuseleko ezinezakhelo zokhuselo, kwaye basebenzise izihluzi ezikhethekileyo xa bejonga iintsimbi ezinobushushu obuphezulu.

4. Abasebenzi abasebenza kwindawo yomlilo okanye kufuphi nendawo yomlilo kufuneka banxibe iiovaroli ezikwaziyo ukugquma ubushushu kunye nokumelana nomlilo. Impahla ye-synthetic chemical fiber (inayiloni, i-polyester, njl.) Impahla akufanele inxibe kufuphi nomlilo.

5. Umbane wesithando somlilo kufuneka uhlolwe rhoqo ngamaxesha athile okuthintela “ukuphelelwa amandla”. Emva kokupholisa, jonga i-lining yesithando somlilo. Xa ubukhulu bomgca wesithando somlilo (ngaphandle kwebhodi ye-asbestos) ingaphantsi kwe-65mm-80mm emva kokugqoka, isithando somlilo kufuneka silungiswe.

6. Ukongeza izixhobo kufuneka uqaphele ukuphepha “iibhulorho” zezinto. Ukushisa okuphezulu kwentsimbi kumacala omabini “iibhulorho” kuya kubangela ukubola kwesithando somlilo ukukhawuleza.

7. Isithando somlilo esitsha se-coreless induction kufuneka senziwe ngezinto ezifanelekileyo, ezifanelekileyo ukuba isinyithi sinyibilike, kwaye somiswe ngokupheleleyo ngaphambi kokongeza izinto zokunyibilikisa. Imimiselo ye-sintering yezinto kufuneka ilandele ngokungqongqo eli nqaku.

8. Izinto ezincibilikayo eziphantsi ezifana ne-aluminiyam kunye ne-zinc kufuneka zongezwe ngononophelo kumanzi aphezulu obushushu obufana nentsimbi. Ukuba izongezo ezisezantsi zokunyibilika ziyatshona phambi kokunyibilika, ziya kubilisa ngamandla kwaye zibangele ukuphuphuma okanye ukudubula. Qaphela ngakumbi xa ufaka intlawulo ye-galvanized tubular.

9. Intlawulo kufuneka yome, ingabi nezinto ezinokutsha, kwaye ingabi ne-rust kakhulu okanye imanzi. Ukubiliswa ngobundlobongela kolwelo okanye izinto ezinokutsha kwintlawulo kunokubangela ukuba isinyithi esinyibilikisiweyo siphuphume okanye sidubule.

10. Iibhola ze-quartz ezihambayo zingasetyenziselwa xa zombini isinyithi kunye ne-coreless induction furnaces zinobungakanani obufanelekileyo. Azenzelwanga ukunyibilika kobushushu obuphezulu besinyithi. Ingxelo yokusebenza yomenzi kufuneka ibe sisikhokelo sokusetyenziswa kwe-crucible.

11. Xa isinyithi sithuthwa kwi-crucible, amacala kunye nezantsi kwi-crucible kufuneka ixhaswe yi-bracket. Inkxaso kufuneka izame ukuthintela i-crucible ukuba ingatyibiliki ngexesha lokuphosa.

12. Ulwazi olufanelekileyo lwekhemistri yokunyibilikisa kufuneka luqondwe. Umzekelo, ukuphendulwa kweekhemikhali njengokubiliswa ngobundlobongela kwekhabhoni kunokubangela umonakalo wesixhobo kunye nokwenzakala komntu. Ukushisa kwesisombululo sokufudumeza akufanele kudlule ixabiso elifunekayo: Ukuba ubushushu bentsimbi etyhidiweyo buphezulu kakhulu, ubomi bentsimbi yesithando somlilo buya kuncitshiswa kakhulu, kuba oku kulandelayo kuya kwenzeka kwi-asidi yesithando somlilo: SiO2 + 2 (C) [Si] +2COLe mpendulo ifikelela kwi-1500℃ kwintsimbi etyhidiweyo Oku ngasentla kwaqhubeka ngokukhawuleza, kwaye kwangaxeshanye ukubunjwa kwentsimbi etyhidiweyo kwatshintsha, i-carbon element yatshiswa, kwaye umxholo we-silicon wanda.

13. Indawo yokufumana kufuneka igcine umthamo ongenamanzi. Ukuqhagamshelana nentsimbi eshushu kunye nolwelo kunokubangela ugqabhuko-dubulo olunobundlobongela kwaye kubangele ukwenzakala komntu. Ezinye iintsalela zinokuthintela isinyithi esinyibilikisiweyo ekungeneni kwitanki echichimayo okanye ilumeke umlilo.

14. Itanki yokuphuphuma kufuneka ilungele ukufumana isinyithi esityhidiweyo nanini na xa i-furnace induction induction isebenza. Ukuchitheka kungavela ngaphandle kwesilumkiso. Kwangaxeshanye, ukuba i-coreless induction furnace kufuneka ikhutshwe ngokukhawuleza kwaye i-barrel (ladle) ayifanelekanga, isithando somlilo esingenasiphelo sinokulahlwa ngokuthe ngqo kwitanki yokuphuphuma.

15. Bonke abasebenzi abafakela amalungu, amalungu, iipleyiti okanye izinto ezinjalo ngokungeyomfuneko kufuneka bazikhwebule kuzo naziphi na iziko elingenasiseko. Indawo yamagnetic ekufutshane nesixhobo inokubangela ukuba kubekho okwangoku nakuphi na ukufakelwa kwentsimbi. Abantu abanee-pacemakers zentliziyo basengozini ngakumbi kwaye kufuneka bahlale kude naso nasiphi na isithando somlilo esingenasiseko.
