Cr12 ishyushye izengurutswe ibyuma

Ibyuma bya Cr12 nicyuma gisanzwe cyuma cyuma, Cr12 nigishinwa Cold Work Alloy Tool Steel. Ubukonje bwakazi bukora Mechanical Properties nibyiza cyane. Ibyuma bya Cr12 bifite imbaraga zo kurwanya abrasion, guhindura mikorobe yimirimo ikonje bipfa ibyuma, ibyuma bikomeye byumuyaga ibyuma, karubone igera kuri 1.5%, chromium igera kuri 11.5%, ubukana bwo kuvura ubushyuhe burashobora kugera kuri HRC 60. Icyuma cya Cr12 igice gishobora gukoreshwa ：

a) silicon ipfa gukoreshwa cyane cyane kubintu bito bito bya loaGBg bisaba kwihanganira kwambara cyane, gushushanya imiterere yoroshye no gupfira ubusa.
b Sisitemu yo gukora imashini ya benGBg isaba kwambara cyane, imiterere igoye ya punch, gupfa, gushiramo, gukora punch, mugihe urupfu rusabwa, gukomera 60 ~ 64HCR.
c) kubikorwa byo gushushanya bipfa gupfa bisabwa, birasabwa gukomera 62 ~ 64HCR.
d) kubirwanya aluminiyumu ikonje bipfa gukubitwa, birasabwa gukomera 60 ~ 62HCR.
e) kuri benGBg ya karubone ya 0,65% kugeza 0,80% yerekana builGBg ibyuma, ubukana 60 ~ 62HCR.
f) irashobora gukoreshwa mugupfa gupfa, gukubita, kuzunguruka, kuzunguruka, gukonjesha heaGBg, kubumba ibumba.
g) irashobora gukoreshwa mububiko bwa plastike ya molGBg.

Guhimba ibikoresho bya Cr12

Shyushya gahoro gahoro kugeza 900 ~ 950 ° C hanyuma wongere ubushyuhe vuba kuri 1050-1100 ° C. Ntugahimbye munsi ya 1020 ° C. Noneho shyira Cr12 buhoro nyuma yo guhimba.

Gufata ibikoresho bya Cr12

Ibikoresho bya GB Cr12 bitangwa muburyo busanzwe kuri annealing kandi imashini. Niba bikenewe re-annealing. Shyushya ibyuma bya Cr12 900 ° C hanyuma Wibike neza, hanyuma ukonje mu ziko. Nyuma ya annealing, ubukana bwa Cr12 ni 255HB Max.

Stress Kugabanya ibikoresho bya Cr12

Mugihe hagomba kuba ibikoresho bikozwe muri Cr12 alloy ibikoresho byuma bikoreshwa cyane cyangwa hasi, kugabanya imiterere yimbere ni byiza mbere yo gukomera kugirango bigabanye amahirwe yo kugoreka. Kugabanya imihangayiko birakenewe cyane, kugabanya imihangayiko bigomba gukorwa nyuma yo gutunganya nabi. Kugira ngo uhangayike, shyushya ibice witonze kugeza kuri 600-650 ° C, emera igihe cyiza (amasaha abiri kuri 25mm yicyiciro). Nkonje mu itanura cyangwa mu kirere. Ibikoresho birangire gutunganywa mbere yo gukomera.

Gukomera ibikoresho bya Cr12

GB Cr12 Imiterere yo gutanga mubisanzwe ni Annealing, bityo gukomera birakenewe. Shyushya ibikoresho bya Cr12 mu itanura ryikirere ryagenzuwe, niba ridafite itanura ryagenzuwe, gukomera birasabwa cyane. Mbere yo gushyushya ibyuma bya Cr12 ibikoresho kugeza kuri 750 ~ 800 ° C, shiramo umwanya uhagije kugeza ubushyuhe burangiye. Noneho uzana 1000-1040 ° C, gukonjesha mu kirere cyangwa kuzimya amavuta.

Kugerageza ibikoresho bya Cr12

Shyushya GB Cr12, Shyushya kimwe ubushyuhe bukenewe butuma igihe cyo kumara amasaha abiri kuri 25mm yicyiciro. Kuramo itanura hanyuma wemere gukonja mu kirere. Ubushyuhe butandukanye buzabona ubukana butandukanye. Ubushyuhe busanzwe ni 204 ° C, nyuma yo gukomera ubukana 61HRc Min.

Gusudira ibikoresho bya Cr12

Muri rusange, ntabwo tugira inama welGBg yicyuma cyifashishwa cyuma ariko abakoresha rimwe na rimwe bahitamo gusudira kugirango birinde ikiguzi cya retooling. Twibuke ko iki cyiciro ari ibyuma bikomera ikirere kandi ko muri welGBg ubuso bwa weld bugera ku bushyuhe bwa 1000 ° C. Kuvunika birashoboka ko bibaho mugihe cyo gukonja keretse hafashwe ingamba zikwiye. Uburyo buzwi bwa welGBg ni hydrogen atom na argon arc. Turagusaba kuvugana na welGBg yawe itanga ibikoresho bigomba kuguha ubufasha bwuzuye namakuru kumashanyarazi ya welGBg.

Nitriding ya Cr12 ibikoresho byuma

Cr12 alloy ibikoresho ibyuma birashobora kuba nitride kugirango bitange ikibanza gikomeye. Nyuma yo kuvura ubushyuhe bwa nitriGBg, Cr12 noneho irwanya cyane kwambara no gutwarwa nisuri. NitriGBg nayo yongera imbaraga zo kurwanya ruswa.

Gusya kwa nyuma ibikoresho bya Cr12

GrinGBg GB Cr12 Icyuma. Hitamo urwego rwukuri rwibiziga mugisha inama nuwakoze grinGBg. Menya neza ko uruziga rwa grinGBg rumeze neza ukoresheje igikoresho cyo kwambara. GrinGBg itose ni amahitamo akoreshwa ukoresheje ibintu byinshi bya coolant. Niba grinGBg yumye yitabaje kugirango ukoreshe uruziga rworoshye cyane.
