Inkcazo yentsimbi

Insimbi ibhekisela kwi-iron carbon alloy kunye nomxholo wekhabhoni we-0.0218% ~ 2.11%.Intsimbi ye-alloy inokufumaneka ngokudibanisa i-Cr, i-Mo, i-V, i-Ni kunye namanye amacandelo e-alloy kwintsimbi eqhelekileyo, kwaye yonke intsimbi yethu yokubumba yeyentsimbi ye-alloy.

Kukho iindlela ezintathu eziphambili zokutshintsha iimpawu zentsimbi:

Ukuqulunqwa kwe-alloy

Ikhabhoni: C

Ukwandisa ukuqina kwezicubu ezilukhuni;

Ukwakhiwa kweCarbide, ukuphucula ukuxhathisa ukunxiba;

Ukunciphisa ubunzima;

Ukunciphisa ukuthengiselana

Cr: Cr

Ukuphucula ubulukhuni bentsimbi, ukwenza i-chromium carbide enzima kwaye ezinzileyo, ngaloo ndlela kuphuculwe ukuchasana nokunxiba;

Inokuphucula ukuqina kwentsimbi;

Xa umxholo we-Cr udlula i-12%, awunyangeki kwi-corrosion kwaye ubonelela ngokujikeleza okulungileyo kokupholisha

Mo, Mo

I-Mo yinto eyomeleleyo yokwenza i-carbide, ukuphucula ukuxhathisa ukunxiba;

I-Mo> 5% inokuthintela ukuvutha komsindo okubangelwa zezinye izinto ze-alloying.

Ibonelela ngobulukhuni obomvu, amandla okushisa;

Ukuphucula ukuqina kunye nokuzinza komsindo

V: V

Inokwenza ubulukhuni obuphezulu be-carbide, iphucule ukumelana nokunxiba;

Cokisa ubungakanani obuziinkozo bentsimbi ukunciphisa ubuntununtunu bobushushu obugqithisileyo

Ukuphucula amandla entsimbi, ukuqina kunye nokuzinza kwe-teering

Nickel: Hayi

I-Ni inokuphucula ukuqina kwentsimbi;

U-Ni unokucokisa iinkozo

Isulfure (S)

Ihlala ikhona kwintsimbi ngendlela ye-MnS, enokuphucula amandla okusika izinto ngokukrazula ukuqhubeka kwe-matrix kunye nokuwohloka kokuqina, ukumelana nokugqwala, ukujikeleza kwe-optical, ukukhutshwa kwe-machining kunye ne-etching properties.

2. Inkqubo yokunyibilikisa

Inkqubo yentsimbi eqhelekileyo

I-Electroslag remelting (ESR)

I-billet erhabaxa ibekwe kwiziko le-electroslag, kwaye umbane onamandla ugqithiselwa ukwenza iziko livelise ubushushu obuphezulu kakhulu, ukuze i-billet erhabaxa inyibilike ibe yintsimbi etyhidiweyo, equkuqela nge-electroslag, kwaye ukungcola kuyahluzwa kwaye kubhengezwe yi. i-electroslag, ukwenzela ukuba kuphunyezwe umphumo wokuhlanjululwa.Isantya sokunyibilika sisonke siyakhawuleza, kodwa obunye ubumdaka obucokisekileyo abususwa.

Ukunyibilikisa iarc yevacuum (VAR)

Kwisithando somlilo, umbane onamandla usetyenziswa kwi-embryo yensimbi, i-bottom ye-embryo iqala ukunyibilika, kwaye ukungcola kuphuphuma kwigesi kwaye kuphonswe kude, ngaloo ndlela kuphuculwe ukucoceka kwentsimbi.Ngaphezu koko, yomelela ithontsi ngethontsi, ngesantya esikhawulezayo sokuqina, kwaye inyama iba xinene kakhulu.Ibonakaliswe ngokususwa ngokucokisekileyo kokungcola, kodwa isantya sokunyibilika sicotha.

3. Unyango lobushushu

Ukunyangwa kobushushu bentsimbi kubhekiselele kwinkqubo yokufudumeza kunye nokupholisa, kunye nokutshintsha iimpawu zentsimbi ngokulawula ubushushu bokufudumala, ukubamba ixesha kunye nesantya sokupholisa sentsimbi, ukwenzela ukuba kuhlangabezane neemfuno zokucubungula okanye ukusetyenziswa.

Iinkqubo eziphambili zokunyanga ubushushu zezi: annealing, quenching, tempering.

Intsimbi yokufa ihlelwa ngokusetyenziswa

1. Ukusebenza okubandayo kwentsimbi

Umsebenzi obandayo die steel isetyenziswa ikakhulu ukwenza imixokelelwane ngokucinezela workpiece ebandayo.Okufana nokufa ngenqindi okubandayo, ukufa kwentampu ebandayo, ukufa komzobo obandayo, ukufa kwesitampu, ukufa kwe-extrusion ebandayo, ukucinezela intambo yokufa kunye nokucofa umgubo.Iintsimbi zokufa ezibandayo zisusela kwiintsimbi zezixhobo zekhabhoni ezahlukeneyo, iintsimbi zesixhobo sealloyi, iintsimbi zesixhobo esinesantya esiphezulu ukuya kumgubo wentsimbi yesixhobo esinesantya esiphezulu kunye nomgubo wentsimbi yokufa.

2. Umsebenzi oshushu ufe intsimbi

Intsimbi yokusebenza eshushu isetyenziselwa ukuvelisa iifa ngenxa yoxinzelelo lwe-workpiece phantsi kobushushu obuphezulu.Okufana nokufa okushushu, ukufa okutshisayo, ukufa kokuphosa, ukufa okutshisa okutshisayo.Umsebenzi oshushu osetyenziswa ngokuqhelekileyo u-die steel uthi: i-carbon alloy alloy die steel ephakathi kunye nephezulu kunye ne-Cr, W, Mo, V kunye nezinye izinto ze-alloy;I-alloy high austenitic heat resistant die steel ngamanye amaxesha isetyenziselwa ukwenza umsebenzi oshushu wentsimbi eneemfuno ezizodwa.

3. Intsimbi yokubumba yeplastiki

Ngenxa yeendidi zeplastiki, iimfuno zeemveliso zeplastiki zahluke kakhulu, ukuveliswa kwezinto zokubumba zeplastiki kukwabeka phambili iintlobo ezahlukeneyo zeemfuno.Ngoko ke, amazwe amaninzi aphuhlileyo kwimizi-mveliso aye abumba uluhlu olubanzi lokungunda kwentsimbi yeplastiki.Kubandakanya intsimbi ye-carbon structural, i-carburizing plastic die steel, i-plastic pre-hard die steel, i-plastic egugayo i-dies steel, i-corrosion resistant die steel, i-plastic yokufa yensimbi elula, i-plastic die steel die steel, intsimbi yokuguga ye-martensitic kunye nesipili sokugulisa iplastiki. .
