Mold karfe (kwalba amfrayo mold / PET mold / tube billet mold / allura mold)
Ma'anar karfe
Karfe yana nufin ƙarfe carbon gami da carbon abun ciki na 0.0218% ~ 2.11%.Alloy karfe za a iya samu ta hanyar ƙara Cr, Mo, V, Ni da sauran gami aka gyara a cikin talakawa karfe, kuma duk mu mold karfe nasa ne gami karfe.
Akwai manyan hanyoyi guda uku don canza kaddarorin karfe:
Alloy abun da ke ciki

Cr: Cr
Inganta taurin karfe, samar da chromium carbide mai wuya kuma tsayayye, ta haka inganta juriya;
Za a iya inganta hardenability na karfe;
Lokacin da abun ciki na Cr ya wuce 12%, yana da juriya na lalata kuma yana ba da jujjuyawar gogewa mai kyau
Mo, Mo
Mo ne mai karfi carbide kafa kashi, inganta lalacewa juriya;

zai iya samar da babban taurin carbide, inganta juriya;
Tace girman hatsin karfe don rage yawan zafin jiki
Inganta ƙarfin ƙarfe, ƙarfi da kwanciyar hankali
Nickel: Ni
Ni iya inganta hardenability na karfe;
Ni zan iya tace hatsi
Sulfur (S)
Sau da yawa yana wanzuwa a cikin karfe a cikin nau'i na MnS, wanda zai iya inganta ikon yanke kayan ta hanyar fasa ci gaba da matrix da kuma lalata taurin, juriya na lalata, jujjuyawar gani, injin fitarwa da kayan etching na kayan.
2. Tsarin narkewa
Tsarin ƙera ƙarfe na yau da kullun
Electroslag remelting (ESR)
Ana sanya rough billet a cikin tanderun electroslag, sannan kuma ana wucewa mai ƙarfi mai ƙarfi don sanya wutar ta samar da zafin jiki mai yawa, ta yadda za a narkar da tarkacen billet ɗin zuwa narkakkar karfe, wanda ke gudana ta cikin electroslag, kuma ana tace ƙazanta da kuma haɗa shi da shi. da electroslag, don cimma sakamakon tsarkakewa.Matsakaicin yawan narkewa yana da sauri, amma wasu ƙazanta masu kyau ba a cire su ba.
Vacuum Arc Remelting (VAR)
A cikin tanderun wuta, ana shafa wutar lantarki mai ƙarfi a kan tayin ƙarfe, ƙasan tayin ya fara narkewa, ƙazanta kuma ta yi tururi ta zama iskar gas kuma a watsar da ita, ta haka ne ke inganta tsaftar ƙarfe.Bugu da ƙari, an ƙarfafa digo ta digo, tare da saurin ƙarfafa ƙarfi, kuma nama ya zama mai yawa.Ana siffanta shi ta hanyar kawar da ƙazanta sosai, amma gabaɗayan remelting ɗin yana jinkirin.
3. Maganin zafi
Maganin zafi na karfe yana nufin tsarin dumama da sanyaya, da canza kaddarorin ƙarfe ta hanyar sarrafa zafin dumama, riƙe lokaci da saurin sanyi na ƙarfe, don biyan buƙatun sarrafawa ko amfani.
Babban tsarin kula da zafi shine: annealing, quenching, tempering.
Die karfe an rarraba bisa ga amfani
1. Cold aiki mutu karfe
Cold aikin mutu karfe ne yafi amfani da tsirar molds ga latsa sanyi workpiece.Kamar mutun naushi sanyi, mutuƙar tambarin sanyi, mutuƙar zane mai sanyi, mutuƙar tambari, mutuwar sanyi mai mutuƙar sanyi, mutun danna zaren mutu da matsi da foda.Cold aiki mutu karafa Range daga daban-daban carbon kayan aiki karfe, gami kayan aiki steels, high gudun kayan aiki karfe to foda high gudun kayan aiki steels da foda high gami mutu steels.
2. Aikin zafi mutu karfe
Hot aikin mutu karfe ne yafi amfani da tsirar mutu ga matsa lamba machining na workpiece karkashin high zafin jiki.Irin su mutuƙar ƙirƙira mai zafi, mutuƙar zafi mai zafi, mutun jifa, mutuƙar tashin hankali.Babban aiki mai zafi mutu karfe shine: matsakaici da babban carbon alloy mutu karfe tare da Cr, W, Mo, V da sauran abubuwan gami;High gami austenitic zafi resistant mutu karfe ne wani lokacin amfani da tsirar zafi aikin mutu karfe da musamman bukatun.
3. Filastik karfe karfe
Saboda nau'in filastik iri-iri, buƙatun samfuran filastik suma sun bambanta sosai, kera kayan ƙirar filastik kuma sun gabatar da buƙatu daban-daban.Saboda haka, da yawa masana'antu kasashe sun kafa wani m kewayon roba mold karfe jerin.Ciki har da carbon tsarin karfe, carburizing filastik mutu karfe, pre-hardening filastik mutu karfe, tsufa hardening filastik mutu karfe, lalata resistant filastik mutu karfe, sauki yankan filastik mutu karfe, hade hardening filastik mutu karfe, martensitic tsufa karfe da madubi polishing filastik mutu karfe .
