Insimbi yesikhunta -(isikhunta sebhodlela sombungu / isikhunta se-PET / isikhunta se-tube billet / isikhunta sokujova)

Incazelo yensimbi

Insimbi ibhekisela kungxube ye-iron carbon alloy enokuqukethwe kwekhabhoni engu-0.0218% ~ 2.11%.Insimbi ye-alloy ingatholakala ngokungeza i-Cr, Mo, V, Ni nezinye izingxenye ze-alloy zibe yinsimbi evamile, futhi yonke insimbi yethu yokubumba ingeyensimbi ye-alloy.

Kunezindlela ezintathu eziyinhloko zokushintsha izakhiwo zensimbi:

Ukwakhiwa kwe-alloy

Ikhabhoni: C

Ukwandisa ubulukhuni bezicubu eziqinile;

Ukwakhiwa kwe-Carbide, ukuthuthukisa ukumelana nokugqoka;

Yehlisa ukuqina;

Ukwehliswa kwe-solderability

Cr: Cr

Thuthukisa ubulukhuni bensimbi, wenze i-chromium carbide eqinile futhi ezinzile, ngaleyo ndlela uthuthukise ukumelana nokugqoka;

Ingathuthukisa ukuqina kwensimbi;

Uma okuqukethwe kwe-Cr kudlula u-12%, kumelana nokugqwala futhi kunikeza ukuzungezisa okuhle kokupholisha

Mo, Mo

I-Mo iyisici esiqinile sokwenza i-carbide, ithuthukise ukumelana nokugqoka;

I-Mo > 5% inganqanda ukufutheka okubangelwa ezinye izakhi ze-alloying.

Inikeza ubulukhuni obomvu, amandla okushisa;

Thuthukisa ukuqina nokuzinza kwentukuthelo

V: V

Ingakha ubulukhuni obuphezulu be-carbide, ithuthukise ukumelana nokugqoka;

Cwenga usayizi wokusanhlamvu wensimbi ukuze unciphise ukuzwela ukushisa ngokweqile

Thuthukisa amandla ensimbi, ukuqina kanye nokuzinza kwe-teering

Nickel: Hayi

I-Ni ingathuthukisa ukuqina kwensimbi;

Ningakwazi ukucwenga okusanhlamvu

Isibabule (S)

Ivamise ukuba khona ngensimbi ngendlela ye-MnS, engathuthukisa ikhono lokusika lezinto ezibonakalayo ngokuchoboza ukuqhubeka kwe-matrix kanye nokuwohloka kokuqina, ukumelana nokugqwala, ukujikeleza kwe-optical, ukukhipha imishini kanye nezakhiwo ze-etching zento.

2. Inqubo yokuncibilikisa

Inqubo ejwayelekile yokwenza insimbi

I-Electroslag remelting (ESR)

I-billet emangelengele ibekwe esithandweni se-electroslag, futhi kudluliswa amandla amanje anamandla okwenza isithando somlilo sikhiqize izinga lokushisa eliphakeme kakhulu, ukuze i-billet enzima incibilike ibe yinsimbi encibilikisiwe, egeleza nge-electroslag, futhi ukungcola kuhlungwe futhi kudsorbed by. i-electroslag, ukuze kuzuzwe umphumela wokuhlanzwa.Isilinganiso sokuncibilika sisonke siyashesha, kodwa okunye ukungcola okuhle kakhulu akususiwe.

I-vacuum arc remelting (VAR)

Esithandweni se-vacuum, amandla kagesi anamandla asetshenziswa kumbungu wensimbi, indawo engaphansi yombungu iqala ukuncibilika, futhi ukungcola kuhwamuka kube igesi futhi kuphonswe kude, ngaleyo ndlela kuthuthukisa ukuhlanzeka kwensimbi.Ngaphezu kwalokho, iyaqina ihle ngeconsi, inesivinini esisheshayo sokuqina, futhi izicubu ziba minyene kakhulu.Ibonakala ngokususwa okuphelele kokungcola, kodwa izinga lokuncibilika lihamba kancane.

3. Ukwelashwa kokushisa

Ukwelashwa kokushisa kwensimbi kusho inqubo yokushisa nokupholisa, nokuguqula izakhiwo zensimbi ngokulawula izinga lokushisa lokushisa, ukubamba isikhathi kanye nesivinini sokupholisa sensimbi, ukuze kuhlangatshezwane nezidingo zokucubungula noma ukusetshenziswa.

Izinqubo eziyinhloko zokwelapha ukushisa yilezi: i-annealing, quenching, tempering.

I-Die steel ihlukaniswa ngokuya ngokusetshenziswa

1. Ukusebenza okubandayo kwensimbi

Cold work die steel isetshenziswa ikakhulukazi ukwenza isikhunta ngokucindezela workpiece ebandayo.Okufana nokufa okubandayo, ukunyathela okubandayo, ukufa komdwebo obandayo, ukufa kokunyathela, ukufa kwe-extrusion okubandayo, ukufa kokucindezela intambo kanye nokufa kokucindezela okuyimpushana.Izinsimbi ezisetshenziswayo ezibandayo zisukela ezinsimbini zamathuluzi ekhabhoni ahlukahlukene, izinsimbi zamathuluzi engxubevange, izinsimbi zamathuluzi anesivinini esiphezulu kuye kwezinsimbi zamathuluzi esivinini esikhulu nezinsimbi eziyimpushana eziwuketshezi.

2. Hot work die steel

Hot work die steel isetshenziswa ikakhulukazi ukukhiqiza efa for machining ingcindezi workpiece ngaphansi lokushisa eliphezulu.Okufana ne-hot forging die, i-hot extrusion die, die casting die, ukufa okucasulayo okushisayo.Insimbi yensimbi esetshenziswa kakhulu eshisayo yile: insimbi ephakathi nephezulu ye-carbon alloy ene-Cr, W, Mo, V nezinye izakhi ze-alloy;I-high alloy austenitic heat resistant die steel ngezinye izikhathi isetshenziselwa ukwakha insimbi eshisayo yokusebenza enezidingo ezikhethekile.

3. Plastic isikhunta steel

Ngenxa yezinhlobonhlobo zepulasitiki, izidingo zemikhiqizo yepulasitiki nazo zihluke kakhulu, ukukhiqizwa kwezinto zokubunjwa kwepulasitiki nakho kubeka phambili izidingo ezihlukene ezahlukene.Ngakho-ke, amazwe amaningi athuthukile ezimbonini enze uchungechunge olubanzi lwensimbi yokubumba yepulasitiki.Kubandakanya i-carbon structural steel, carburizing plastic die steel, plastic die steel pre-harding plastic die steel, ipulasitiki eqinile egugayo, insimbi engagqwali engagqwali, ukusika okulula kwe-plastic die steel, ukuqina okubalulekile kwe-plastic die steel, insimbi yokuguga ye-martensitic nesibuko sokupholisha ipulasitiki .
