Yadda ake amfani da tsarin sintering don harsashin tace raga na ƙarfe

Shirye-shiryen kayan da aka sarrafa:
Zaɓi kayan da suka dace, kamar foda na ƙarfe, barbashi na polymer, ko kayan yumbu, sannan ka zaɓi kayan da suka dace bisa ga buƙatun da aikace-aikacen sinadarin tacewa.
Bayan shirya kayan, yana iya zama dole a haɗa kayan, foda, rarraba girman barbashi, da kuma abubuwan ɗaurewa masu yiwuwa a wani rabo don samar da manna iri ɗaya.
Ciyar da abinci a cikin gyare-gyaren:
Idan kayan da aka yi amfani da su a cikin foda ne ko kuma granulated, yana iya buƙatar a niƙa shi a kuma yi masa siffar ƙwallon don ya samar da ƙwayoyin zagaye. Yi amfani da injin matsewa don matsawa da siffanta kayan zuwa gaɓoɓin kore na siffar da ake so (abin da ba a haɗa shi da matattara ba). Ana iya cimma wannan ta hanyar hanyoyi kamar allurar ƙera, extrusion molding, da matsi molding.

Busasshe:
Ana buƙatar busar da busasshen billet ɗin kore don cire danshi daga ciki. Yawanci ana busar da shi ta hanyar iska ko ɗakunan yin burodi.

sinter:
Sanya busasshen kore a cikin tanda mai zafi don yin sintering. Tsarin sintering shine a dumama kayan zuwa babban zafin jiki, wanda ke sa ƙwayoyin kayan su haɗu tare kuma su samar da tsarin tacewa mai ƙarfi.

A lokacin aikin sintering, ana iya buƙatar waɗannan matakai:

Yin amfani da injin tsotsa: Fara na'urar injin tsotsar iska don cire iskar da ke cikin ɗakin sintering da iskar gas da aka haɗa da toshewar matsi. Yawanci, ya zama dole a kwashe mataki na biyu zuwa 1.3 × 10 ^ -2 Pa (ko ya danganta da takamaiman yanayin).

Dumamawa da kuma cire gas: Tanderun yana ci gaba da yin famfo a zafin 400-500 ℃ ta hanyar dumama wutar lantarki, yana rage matsin lamba na toshewar matsi sannan a hankali yana rugujewa da tururi yana fitar da iskar gas da ke sha a ciki da wajen toshewar matsi, da kuma hanyoyin samar da sinadarai kamar man shafawa da kuma sinadaran granulation da aka ƙara yayin aikin matsi.

Ciko da iskar argon: Domin yin sintiri a ƙarƙashin yanayi mai kariya, ɗakin sintering yana cike da iskar argon a wannan lokacin.

Zafin dumama zuwa sintering: Ƙayyade kuma sarrafa zafin sintering bisa ga kayan daban-daban. Yawan zafin jiki na iya haifar da laushi da nakasa samfurin, yayin da ƙarancin zafin jiki na iya tsawaita lokacin sintering da rage amfani da kayan aiki.

Rufewa: A kiyaye zafin sintering na tsawon lokaci don aiwatar da ayyuka kamar yawan danshi, raguwar ramuka, da kuma canza launin kore.

Sanyaya da sarrafawa:Bayan an gama yin sintering, ana buƙatar sanyaya sinadarin matattara. Yawan sanyaya yana da tasiri ga aikin samfurin, don haka ya kamata a kula da saurin sanyaya don kiyaye tsarin sintered. Maganin saman kamar shafa ko shafa shi ma yana iya zama dole don haɓaka aikin sinadarin matattara.

Yankewa da siffantawa:
Ana iya buƙatar a yanke kuma a siffanta abin da ke cikin matattarar domin a sami girman da siffar da ake so.

Gwajin aiki da marufi:
Akwatin tacewa da aka samar yana buƙatar yin gwajin aiki don tabbatar da cewa ya cika ƙa'idodi da ƙa'idodi masu inganci. Bayan ya ci jarrabawar, galibi ana shirya sinadarin tacewa don jigilar kaya da adanawa.
