    A crucibletukunyar yumbu ne da ake amfani da shi don riƙe ƙarfe don narkewa a cikin tanderu. Wannan babban inganci ne, crucible matakin masana'antu wanda masana'antar kafa ta kasuwanci ke amfani da ita.

    Abin da Yake Yi:

    Ana buƙatar ƙugiya don jure matsanancin yanayin zafi da ake fuskanta a cikin karafa masu narkewa. Dole ne kayan ƙwanƙwasa ya sami matsayi mafi girma fiye da na ƙarfe da aka narke kuma dole ne ya sami ƙarfi mai kyau ko da lokacin farin zafi.

    Mai yiyuwa ne a yi amfani da karfen da aka kera a gida don narkar da karafa irin su zinc da aluminum, saboda wadannan karafa na narke a yanayin zafi kasa da na karfe. Duk da haka ƙwanƙwasa (flaking) na saman ƙwanƙolin ƙarfe na ciki yana da matsala. Wannan ma'auni na iya gurɓata narke da kuma siriri ga ganuwar da ke da ƙarfi da sauri. Karfe crucibles zai yi aiki idan kun fara farawa kuma kada ku damu da ma'amala da sikelin.

    Abubuwan da ake amfani da su na yau da kullun da ake amfani da su a cikin gini sune yumbu-graphite, da silicon-carbide mai haɗin carbon. Wadannan kayan zasu iya jure yanayin zafi mafi girma a cikin aikin kafa na yau da kullun. Silicon carbide yana da ƙarin fa'idar kasancewar abu mai dorewa sosai.

    Clay Graphite Bilge Shape crucibles an ƙididdige su don 2750 ° F (1510 ° C). Za su yi amfani da zinc, aluminum, tagulla / tagulla, azurfa da gwal. Masana'antun sun ce ana iya amfani da su don simintin ƙarfe. Anyi a Amurka!

    Siffofi masu lalacewa:

    An siffata da siffa mai siffa ("B" Siffar) kamar ganga ta giya. Girman "bilge" shine diamita na crucible a mafi girman wurinsa. Idan babu diamita na birge da aka nuna to babban diamita shine matsakaicin faɗin.

    Ƙa'idar babban yatsan hannu ta bayyana cewa # na "bilge" crucible yana ba da kusan ƙarfin aiki a cikin fam na aluminum. Don tagulla ko tagulla yi amfani da crucible sau 3 #. Misali # 10 crucible zai riƙe kusan fam 10 na aluminum da fam 30 na tagulla.

    Masu sha'awar sha'awa da masu sha'awar sha'awa na yau da kullun suna amfani da crucibles ɗin mu na “B”. Waɗannan ƙwaƙƙwaran inganci ne, ƙimar darajar kasuwanci mai dorewa.

    Bincika allunan da ke ƙasa don nemo madaidaicin girman aikinku.

    Yadda Ake Amfani da shi:

    Dole ne a yi amfani da duk abubuwan da ake amfani da su tare da ƙwanƙwasa masu dacewa (kayan ɗagawa). Ƙunƙarar da ba ta dace ba na iya haifar da lalacewa ko cikakkiyar gazawar ƙugiya a mafi munin lokaci mai yiwuwa.

    Ana iya sanya faifai na kwali tsakanin ƙugiya da ginin tanderun kafin dumama. Wannan zai ƙone, barin wani Layer na carbon a tsakanin kuma ya hana crucible daga manne a kasa tanderu. Rufin Plumbago (Carbon Black) yana yin abu iri ɗaya.

    Zai fi kyau a yi amfani da ƙugiya daban-daban don kowane nau'in ƙarfe don guje wa gurɓatawa. Hakanan tabbatar da zubar da crucible gaba daya bayan amfani. Karfe da aka bari don ƙarfafawa a cikin ƙugiya na iya faɗaɗa kan sake dumama kuma ya lalata shi.

    Da fatan za a fusata sabon crucibles ko waɗanda ke cikin ajiya. Yi zafi da kullun maras kyau don 2 hours a 220 F (104 C). (Yi amfani da isassun iska. Sabbin ƙwanƙwasa za su sha hayaƙi yayin da glaze ke saitawa.) Sa'an nan kuma kunna kumfa da ba komai a ciki zuwa jan zafi. Bada crucible ya yi sanyi zuwa ɗaki a cikin tanderun kafin amfani. Yakamata a bi wannan hanya don DUK sabbin ƙwanƙwasa da kuma duk wani ƙugiya da ƙila an fallasa ga yanayin ɗanɗano a cikin ajiya.

    Ajiye duk crucibles a bushe wuri. Danshi zai iya haifar da ƙugiya don tsage akan dumama. Idan ya kasance a cikin ajiya na ɗan lokaci yana da kyau a maimaita zafin.

    Silicon carbide crucibles su ne mafi ƙarancin nau'in da za su iya sha ruwa a cikin ajiya kuma yawanci ba sa buƙatar yin fushi kafin amfani. Yana da kyau a harba sabon kumfa zuwa jan zafi kafin fara amfani da shi don fitar da taurare kayan masana'anta da masu ɗaure.

    Yakamata a sanya kayan a cikin kwandon shara sosai. KADA KADA KA “kwankwasa” ƙugiya, kamar yadda kayan zai faɗaɗa akan dumama kuma zai iya fashe yumbu. Da zarar wannan abu ya narke a cikin "dugansa", a hankali ƙara ƙarin kayan cikin kududdufi don narkewa. (GARGAƊI: Idan WANI ɗanshi ya kasance akan sabon abu fashewar tururi zai faru). Har yanzu, kar a sanya kayan cikin karfe sosai. Ci gaba da ciyar da kayan cikin narkewa har sai an narke adadin da ake buƙata.

    GARGADI!!!: Girgizar ƙasa tana da haɗari. Narkar da ƙarfe a cikin tukwane yana da haɗari. Zuba ƙarfe a cikin gyare-gyare yana da haɗari. Ƙunƙwasa na iya gazawa ba tare da faɗakarwa ba.

    BCS Tushe mai tushe shine babban tsaunin zafin jiki da ake amfani dashi don ɗaga tukunyar jirgi zuwa yankin zafi na tanderun.

    Abin da Yake Yi:

    Ana amfani da tubalin tushe gabaɗaya a cikin tanderun da aka harba iskar gas don ɗaga ƙwanƙolin sama don kada harshen wuta ya fashe kai tsaye cikin bakin bakin bangon crucible. Idan aka ƙyale harshen wuta ya bugi ƙwanƙwaran kai tsaye zai iya haifar da ɓarnawar bangon crucible don haka ya gajarta rayuwarsa. Hanyar da ta dace don hana hakan ita ce yin amfani da shingen tushe don tayar da crucible daga yankin mai ƙonewa.

    Ƙirar kullun kuma yana ba shi damar kasancewa a cikin "yankin zafi" na tanderun. Ko da yake harshen wuta yana shiga jikin murhu a kasa yankin mafi zafi shine daga tsakiya har zuwa sama.
