Intshayelelo kumsebenzi obandayo wokufa

Umsebenzi obandayo wensimbi usetyenziselwa ukubetha, ukutshakaza, ukugoba, ukugqobhoza okubandayo, ukugqobhoza okubandayo, ukuxhaphaza okuphezulu kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobunzima obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nobuchule obaneleyo kunye nokubaninzi. Ukwahlulahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwa kunye nohlobo olukhethekileyo. Umzekelo, umsebenzi obandayo obandayo ufefa intsimbi e-United States ibandakanya amabanga amane ensimbi: 01, A2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2, D2. Ukuthelekisa amabakala ensimbi ye-Allound Alloy Alloy Dea yensimbi kumazwe ahlukeneyo abonakaliswa kwiTheyibhile ye-Sk, kuquka i-Sk Drice Speents Steel, kunye ne-9 skhmo yamabakala angama-24 apheleleyo. I-China GB / T12992000 Isixhobo se-Alloty Stones Stones sentsimbi siquka iindidi ezili-11 zentsimbi, zenza uthotho olupheleleyo. Ngotshintsho kwitekhnoloji yokuqhubela phambili, izixhobo eziqhotyoshelweyo kunye nemfuno yokufunwa kweembumbulu, izingcungcutheka ezisisiseko azinakuhlangabezana neemfuno. I-Japan Mills zentsimbi kunye nezixhobo eziphambili ze-European kunye nabavelisi bensimbi abaye baqulunqe umsebenzi obandayo wensimbi, kwaye ngokuthe ngcembe kwenziwa ngokuthe ngcembe intsimbi yentsimbi yomsebenzi obandayo.

I-Allow Allow Allound icime indlela ebandayo yentsimbi

Ngokuphuhliswa kwetekhnoloji yonyango lobushushu, ngakumbi ukusetyenziswa kwetekhnoloji yokufumana itekhnoloji ye-vacuum kwishishini lokuxhela, ukuze kuncitshiswe ukunciphisa ukungcungcuthekiswa, amanye amasikizi aphantsi komoya otyhidiweyo aphuhlisiwe ekhaya nakwamanye amazwe. Olu hlobo lwensimbi lufuna ukungabi nalukhuni kwaye unyango lobushushu lunengxaki encinci, amandla amahle kunye nobunzima, kwaye unciphise ukunyangwa okuthile. Nangona umsebenzi obandayo obandayo obandayo wentsimbi (enje nge-D2, A2) Unoxinzelelo oluhle, lunomxholo ophezulu kwaye ubiza kakhulu. Ke ngoko, ezinye izinto ezihlangeneyo eziphantsi kwe-nowal-sciods ziye zaphuhliswa ekhaya nakwamanye amazwe. Olu hlobo lwentsimbi ngokubanzi luqukethe izinto zefloy ze-cr kunye ne-mn yezakhiwo zokuphucula ukuqaqamba. Umxholo opheleleyo wezinto ze-alloy ngokubanzi yi <5%. Ilungele indawo yokuchaneka kweebatch ezincinci zemveliso. I-FORDS entsokothileyo. Amabanga amele intsimbi aquka i-A6 eUnited States, i-ACD37 evela kwi-Fitachi Thieli, esuka kwi-Chinese GD, i-Chinese Steet, inamandla athile, ukuqina kunye nozinzo oluhle. Ingasetyenziselwa ukwenza isitampu esibandayo esijongene nokuhamba kunye nokuqhekeka. Ubomi obuphezulu.

Idangatye elicinyiwe intsimbi yentsimbi

Ukwenzela ukuthoba umjikelo wokwenza ubumba, yenza lula inkqubo yobushushu yonyango, gcina amandla kwaye unciphise iindleko zokwenza umbungu. IJapan iphuhlise umsebenzi obandayo obandayo obandayo wokufa kwezitho ezifungukayo ngeflakisi. I-AIIICHI ye-SX155v (7crsimnuv), sx4 (i-SX4), i-HIT8 yensimbi ye-HMD5, HMD1, i-HMD1, i-datong yensimbi ye-China ye-China ye-China iphuhlise i-7CR7SIMMONOV. Olu hlobo lwensimbi lungasetyenziselwa ukufudumeza i-blade okanye amanye amalungu ombungu usebenzisa umpu we-oxyacellylene spray okanye ezinye izitshisi emva kokuba i-slold iqhubekile kwaye ipholile. Ngokubanzi, inokusetyenziswa ngokuthe ngqo emva kokucinywa. Ngenxa yenkqubo yayo elula, isetyenziswa ngokubanzi eJapan. Uhlobo lommeli wentsimbi lolu hlobo lwensimbi yi-7crimNNMNMONOV, enokukhubeka. Xa i-φ80mm yensimbi icinyiwe, ubunzima kumgama we-30mm ukusuka kumphezulu onokuthi ufikelele kwi-60hrc. Umahluko kubunzima phakathi kwe-core kunye nomphezulu yi-3HRC. Xa ukucingela ilangatye, emva kokuqala nge-180 ~ 200 ° CAME ukuya kwi-900-1000 ° C yokucima umpu, ubunzima obungaphezulu kwe-1.5mm.

Ubunzima obuphakamileyo, ukunxiba okuphezulu okuxhaphakileyo okubandayo kwentsimbi yentsimbi

Ukwenzela ukuphucula ubunzima bomsebenzi obandayo ofayo wensimbi kwaye unciphise i-SEE yentsimbi, iinkampani ezinkulu zemveliso zangaphandle ziye zaphucula uthotho lomsebenzi obandayo kunye nokuxhaphaza okuphezulu. Olu hlobo lwentsimbi ngokubanzi iqulethe malunga ne-1% yekhabhoni kunye ne-8% cr. Ngongezwa kwe-MO, V, kunye nezinye izinto ezikhoyo, iicarbider zayo zilungile, zisasazwe ngokulinganayo, kwaye ubunzima bayo bungaphezulu kakhulu kunelo ye-CR12 Chwetheza kakhulu, ngelixa ukuxhathisa intsimbi, ngelixa ukuxhathisa intsimbi, ngelixa ukuxhathisa intsimbi, ngelixa ukuxhathisa intsimbi. . Ubulukhuni babo, amandla abo aguqukayo, amandla okudinwa amandla kunye nokuqina kokukhathalela kuphezulu, kwaye ukuzinza kwabo okuchasene nokunyeliswa kukuphakama kwe-CRL2 Chwethe i-CRL2 uhlobo lwentsimbi. Zilungele i-punches ehamba ngesantya esiphezulu kunye nesikhululo seenqwelomoya ezininzi. Iindidi zentsimbi ezimeleyo zolu hlobo lwentsimbi yi-DC53 ye-DC53 ngomxholo ophantsi we-v kunye ne-CRU-NORY ngemixholo ephezulu. I-DC53 icinyiwe kwi-1020-10 ukuya kwengama-40 c kwaye ubunzima bunokufikelela kwi-62-63HRC emva kokupholisa umoya. Kungafikelela kubushushu obuphantsi (180 ~ 200 ℃) kunye neqondo lobushushu obuphezulu (500 ~ 550 ℃), ukuqina kwayo kungaphezulu kune-D2, kwaye intsebenzo yayo iphezulu kune-D2; Emva kokuba enxibe i-Cer-nxiba kwaye uqengqeleka, udlalwe kwaye unomdla kwi-850-870 ℃. Ngaphantsi kwe-30 ℃ / iyure, ipholile ukuya kwi-650 ℃ kwaye ikhululwe, ubunzima obungafikelela kwi-620 ~ 110hb, iqondo lokungasebenzi linokuthuthuzela i-D10Hb, ukunyangwa kunye nobunzima bungcono kune-D2.

Isiseko sentsimbi (intsimbi enesikhafu esiphezulu)

Insimbi yesantya esiphezulu isetyenziswe phesheya ukuba isebenze kakuhle ukusebenza, umsebenzi obandayo obandayo obandayo ngenxa yokunxiba ngokuchasene ne-Japan ePhakamileyo sk51 (i-W6MCR41). Ukulungiselela ukuziqhelanisa neemfuno zobumba, ubunzima zihlala ziphuculwa ngokunciphisa ubushushu bokuveza, ukucima ubunzima okanye ukunciphisa umxholo wekhabhoni kwisantya esiphezulu. Intsimbi ye-Matrix iphuhliswa kwintsimbi enesikhafu esiphezulu, kunye nokwenziwa kwayo imichiza ilingana nokuqulunqwa kwe-matrix yensimbi yesantya esiphezulu emva kokucinywa. Ke ngoko, inani leecaridedes ezihambahambayo emva kokucinywa lincinci kwaye zisasazwa ngokulinganayo, eziphucula kakhulu ubunzima bentsimbi xa kuthelekiswa nentsimbi enesikhafu esiphakamileyo. I-United States kunye neJapan yazisa iziSethi ezinamaBanga anamaBakala Vascoma, iVascoraTriX1 kunye ne-MOD2 ekuqaleni kweminyaka yo-1970. Kutshanje, i-DRM1, DRM2, DRM3, njl njl sele iphuhlisiwe. Ngokubanzi isetyenziselwa ukwenza umsebenzi obandayo wokubumba okufuna ubunzima obuphezulu kunye nokuzinza okunethemba lokulwa nomdla. I-China ikwaphuhlise ezinye iziseko ezisisiseko, ezinje nge-65nb (65CR4W3VNB), 65W8WNB), 65W8CTNTI, 65CRO3W2VSITI kunye nezinye izini. Olu hlobo lwensimbi lunamandla amahle kunye nobunzima kwaye lusetyenziswa kakhulu kwi-punch ebandayo, i-puting ye-pitting ebandayo, amavili aqengqelekayo, i-store ifa, kwaye inokusetyenziswa njengokuphuma okufudumeleyo kuyafa.

I-powder metargergergy yentsimbi

I-Edbb-uhlobo lokukhuphela olubandayo-lubandayo oluphezulu lwensimbi eveliswa ziinkqubo eziqhelekileyo, ngakumbi izixhobo zecandelo elikhulu, zine-carbides enkulu, ihambisa ubunzima, ukusasazeka kunye ne-isotropy yentsimbi. Kwiminyaka yakutshanje, iinkampani ezinkulu zentsimbi ezikhethekileyo ezivelisa isixhobo kunye nensimbi yensimbi igxile ekuphuhliseni uthotho lwe-pollergergergergergergergergery steen kunye nentsimbi yentsimbi yentsimbi. Ukusebenzisa inkqubo ye-meltergergergergy, i-Atomibi yentsimbi ipholile ngokukhawuleza kwaye ii-carbides zenziwe kakuhle kwaye iyunifomu ephucukileyo, i-Graive kunye ne-isotropy yezinto ezibunjiweyo. Ngenxa yenkqubo ekhethekileyo yemveliso, ii-carbides zilungile kwaye iyunifomu yokusebenza kunye nokugaya kunye nokugcoba kuyaphuculwa, kuvumela umxholo wekhabhoni ephezulu, ngaloo dadim no-Adadim no-Adadim no-Adadium ophuhlisa iintlobo zentsimbi ezitsha. Umzekelo, u-Dex40, i-Dex0, Dex80, njl. Njl. Yenza uthotho lwe-powersggy tellings ezifana ne-CPMLV, iCPM3V, CPM15V, njl njl.
