Tšebeliso e nepahetseng le tlhokomelo eali-crucibles tsa silicon carbidephetha karolo ea bohlokoa bophelong ba bona bo bolelele le katlehong ea bona.Mona ke mehato e khothaletsoang bakeng sa ho kenya, ho futhumatsa, ho tjhaja, ho tlosoa ha slag, le ho lokisoa ha li-crucibles ka mor'a tšebeliso.
Ho kenya Crucible:
Pele o kenya, hlahloba sebōpi 'me u rarolle mathata leha e le afe a sebopeho.
Hlakola mesaletsa efe kapa efe ho tloha maboteng a sebōpi le tlase.
Netefatsa ts'ebetso e nepahetseng ea masoba a lutla 'me u hlakole li-blockages.
Hloekisa secheso 'me u netefatse hore se eme hantle hakae.
Hang ha licheke tsohle tse ka holimo li phethiloe, beha crucible bohareng ba setsi sa sebōpi, ho lumella lekhalo la 2 ho isa ho 3-inch pakeng tsa crucible le marako a sebōpi.Lintho tse ka tlaase li lokela ho tšoana le lisebelisoa tsa crucible.
Lelakabe la mollo le lokela ho ama crucible ka ho toba lenonyeletsong le setsi.
Crucible Preheating: Preheating ke ea bohlokoa ho lelefatsa nako ea bophelo ea crucible.Liketsahalo tse ngata tsa tšenyo ea crucible li etsahala nakong ea preheating phase, e ka 'nang ea se ke ea bonahala ho fihlela ts'ebetso ea ho qhibiliha ha tšepe e qala.Latela mehato ena bakeng sa preheating e nepahetseng:
Bakeng sa li-crucible tse ncha, butle-butle eketsa mocheso ka likhato tse 100-150 tsa Celsius ka hora ho fihlela o fihla ho 200 ° C.Boloka mocheso ona ka metsotso e 30, ebe o o phahamisa butle ho 500 ° C ho tlosa mongobo ofe kapa ofe o monyehileng.
Ka mor'a moo, futhumatsa crucible ho 800-900 ° C kapele kamoo ho ka khonehang 'me ue theole mocheso o sebetsang.
Hang ha mocheso oa crucible o fihla sebakeng sa ho sebetsa, eketsa lintho tse nyenyane tse omeletseng ho crucible.
Ho lefisa Crucible: Mekhoa e nepahetseng ea ho tjhaja e kenya letsoho bophelong bo bolelele ba crucible.Qoba ho beha li-ingots tse batang tsa tšepe ka holimo kapa ho li lahlela ka har'a crucible tlas'a maemo afe kapa afe.Latela litataiso tsena bakeng sa ho tjhaja:
Omisa li-ingots tsa tšepe le likotoana tse kholo pele u li kenya ka har'a crucible.
Beha lisebelisoa tsa tšepe ka mokhoa o hlephileng ka har'a crucible, ho qala ka likotoana tse nyenyane e le mosamo ebe u eketsa likotoana tse kholoanyane.
Qoba ho kenya li-ingots tse kholo tsa tšepe sebakeng se senyenyane sa tšepe e metsi, kaha e ka baka ho tsidifala ka potlako, ho bakang ho tiea ha tšepe le ho phatloha ho ka bang teng.
Hloekisa crucible ea tšepe eohle ea metsi pele e koala kapa nakong ea khefu e atolositsoeng, kaha li-coefficients tse fapaneng tsa ho atolosa tsa crucible le tšepe li ka lebisa ho phunyeha nakong ea ho futhumatsa hape.
Boloka boemo ba tšepe e qhibilihisitsoeng ka har'a crucible bonyane 4 cm ka tlase holimo ho thibela ho phalla.
Ho Tlosa Slag:
Eketsa li-slag-removing agents ka ho toba ho tšepe e qhibilihisitsoeng 'me u qobe ho li kenya ka har'a crucible e se nang letho kapa ho li kopanya le tefiso ea tšepe.
Hlohlelletsa tšepe e qhibilihisitsoeng ho netefatsa hore esita le ho ajoa ha li-slag-removing agents le ho li thibela ho itšoara ka marako a crucible, kaha sena se ka baka ho senya le ho senya.
Hloekisa marako a ka hare a crucible qetellong ea letsatsi le leng le le leng la mosebetsi.
Tlhokomelo ka mor'a ho sebelisoa ha Crucible:
Tlosa tšepe e qhibilihisitsoeng ho crucible pele u koala sebōpi.
Ha sebōpi se ntse se chesa, sebelisa lisebelisoa tse loketseng ho senya slag leha e le efe e khomarelang marako a crucible, u hlokomele hore u se ke ua senya crucible.
Boloka masoba a lutla a koetsoe 'me a hloekile.
Lumella crucible hore e pholile ka tlhaho ho mocheso oa kamore.
Bakeng sa li-crucibles tse sebelisoang ka linako tse ling, li boloke sebakeng se omeletseng le se sirelelitsoeng moo ho seng bonolo hore li khathatsoe.
Tšoara li-crucibles ka bonolo ho qoba ho robeha.
Qoba ho pepesa crucible moeeng hang ka mor'a ho futhumatsa, kaha sena se ka baka
