Iyo ukubise '17 4 gushora imari 'mukibanza cyo gushakisha, birashoboka ko ushakisha isasu ryubumaji - igice gikomeye, kirwanya ruswa, kandi gikomeye, byose kubiciro byiza. Ukuri, kuva ku ntebe yanjye, ni akajagari. 17-4 PH idafite umwanda ni ibintu bitangaje, ariko kubihuza nuburyo bwo gushora imari ntabwo ari imyitozo yo kugenzura. Nabonye ibishushanyo byinshi cyane aho byerekanwe na rote, nta kiganiro nyacyo kijyanye no gutunganya ubushyuhe (H900, H1025, nibindi) nyuma yo gutara, bigena cyane cyane imiterere yubukanishi ubona. Aho niho gutandukana akenshi bitangirira.
Allure na Caveat Ako kanya
Amasezerano ntawahakana. Gutera ishoramari reka ubyare umusaruro utoroshye, hafi-net-shusho ya geometrike yaba ari inzozi kumashini kuva mububiko, cyane cyane mubintu bikomeye nka 17-4. Tekereza ibyuma bya turbine, ibikoresho byo kubaga, cyangwa umubiri wa valve ufite ibice byimbere. Imyanda ni ntoya, iyo kubiciro byigiciro, bifite akamaro.
Ariko dore hiccup yambere ifatika: fluidity. 17-4 muburyo bwashongeshejwe ntibitemba nka 304 cyangwa 316. Niba igishushanyo gifite ibice bito cyane cyangwa bisaba kuzuza ibisobanuro birambuye, byuzuye, ushobora guhura nabi cyangwa gufunga imbeho. Ibi twabyize kare hamwe nicyiciro cyamazu ya sensor. Urukuta rwarwo rwari 1,2mm, kandi twari dufite igipimo cya 50% cyo gusiba kugeza igihe twongeye gushushanya sisitemu yo kwinjirira no kongera ubushyuhe bwo gusuka - hanyuma igashyiraho uburyo bwayo bwerekeye imiterere yingano. Buri gihe ni impirimbanyi.
Aha niho uburambe bwumushinga buba butaganirwaho. Iduka risuka gusa ibyuma byoroshye bya karubone birashobora gutsitara nabi hamwe na 17-4. Ukeneye umufatanyabikorwa wumva metallurgie, ntabwo ari molding gusa. Nagize ibiganiro byiza hamwe namakipe ahantu nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Intego zabo z'igihe kirekire gushora imari n'amavuta adasanzwe, nkuko bigaragara kurubuga rwabo tsingtaocnc.com, byerekana ko bakemuye ibibazo byihariye mbere, ni kimwe cya kabiri cyintambara.
Nyuma yo gukina: Aho PH ibera
Iki nigice cyirengagijwe cyane muri RFQs. Ntabwo utera 17-4 PH. Ujugunye 17-4 idafite umwanda muburyo bwo gukemura. Gukomera kw'Imvura biza nyuma. Igice cya as-cast cyoroshye kandi cyoroshye. Noneho ushushe ubivure kuri H-imiterere yagenwe.
Igenzura rikomeye nubushyuhe hamwe nikirere. Niba ugamije H900 kugirango ubone imbaraga nyinshi (hafi 190 ksi tensile), gutandukana na 25 ° F mu itanura birashobora gutuma ubukana budahuye mugukora ibicuruzwa. Twigeze kugira igice cyibice byo guhuza ikirere byananiranye QC kuko itanura ya termocouple yatwaraga; ibice kuruhande rumwe rwa tray byahuye na spec, ibindi sibyo. Byari isomo rihenze mugutekereza ko imiti ivura ubushyuhe yabimenye.
Kandi gutunganya nyuma yo gukomera? Birashoboka ariko birakomeye. Niba ukeneye kuvanaho icyuma gikomeye, kora muri reta ya post-cast, hanyuma ukomere. Umucyo wose urangije nyuma yo gukomera bisaba ibikoresho bya ceramic cyangwa CBN, kandi urimo kureba ibikoresho byambara nkibisiga. Icyitegererezo cyibiciro gihinduka cyane ukurikije uru rutonde.
Kugereranya Ibipimo Mugihe cyo Kuvura Ubushyuhe
Ingingo ifatika iruma abashushanya: gukomera kw'imvura bitera impinduka nkeya, ariko ziteganijwe, impinduka zingana. Ntabwo ari nko kuzimya ibyuma bya karubone, ariko birahari. Kubipimo 100mm, urashobora kubona 0.05mm kugeza 0.1mm. Niba ufite kwihanganira +/- 0.05mm kuri bore ikomeye, ugomba kubara ibi. Ubu buri gihe twubaka ibintu bigabanuka / gukura byihariye kuri H-imiterere muri casting die design kubintu byingenzi. Kwirengagiza ibi bivuze kurangirana nibintu byihariye ariko bitarenze urugero.
Kunanirwa kwukuri kwisi no gukosorwa
Ndibuka umushinga wibikoresho byo mu nyanja-imashini itwara ruswa. Icyerekezo cyari 17-4 PH H1150 kugirango ivange neza imbaraga hamwe no kurwanya ruswa. Abakinnyi basaga neza, batsinze X-ray, ariko bananirwa kwipimisha umunyu hakiri kare kuruta uko byari byitezwe.
Intandaro? Kwangirika hagati. Kumara igihe kinini mubuvuzi bwa 1150 ° F, niba bitagenzuwe neza, birashobora gutuma karbide ya chromium igwa kumupaka wimbuto, ikabura chromium mugace. Gukosora ntabwo byahinduye ibikoresho, ahubwo byahinduye uburyo bwo kuvura ubushyuhe no kwemeza kuzimya vuba nyuma yicyiciro cya anneal. Ibi ntabwo ari ibintu byibitabo; nuburyo bwimikorere nuance wiga mukoresha ibice ibihumbi ukareba icyacitse nimpamvu.
Ngiyo agaciro k'umutanga uhuza casting na mashini. Niba urwego rumwe rugenzura inzira zose kuva kumurongo kugeza igice cyarangiye, nka QSY ihujwe gushora imari na Imashini ya CNC gutanga, gukemura ibibazo bihinduka inzira ifunze. Ntabwo ushinja caster, hanyuma uvura ubushyuhe, hanyuma umukanishi. Ibitekerezo birahita kandi birakorwa.
Igihe cyo Kubikoresha, Igihe cyo Kugenda
None, ni ryari '17 4 gushora imari 'byumvikana? Ubwa mbere, iyo bigoye ari byinshi kandi gutunganya ibiciro bivuye bikomeye byaba bibujijwe. Icya kabiri, mugihe ukeneye guhuza imbaraga zirwanya ruswa hamwe nimbaraga nyinshi mugice kimwe. Icya gatatu, mugihe ufite amajwi yo kwemeza igiciro cyibikoresho bya ceramic.
Ni ryari ugomba kwisubiraho? Kubishusho byoroshye-flange shingiro cyangwa umurongo ugororotse. Imashini gusa. Kubisabwa bisaba kwangirika kwangirika mukugabanya ibidukikije bya acide, ikindi kintu kitagira umwanda gishobora kuba cyiza. Kandi kuri ultra-high-temperature service, ibuka imiterere ya H itakaza imbaraga hejuru ya 600 ° F.
Birakwiye kandi kubaza kubyerekeye ubundi buryo bwo kuvanga. Rimwe na rimwe, duplex idafite ibyuma bishora imari kandi ikozwe neza irashobora gutanga igiciro cyiza / igipimo cyimikorere kubisabwa. Injeniyeri nziza yo gushinga azagira iki kiganiro nawe, aho kwakira ibyanditswe gusa.
Ibicuruzwa bitanga amasoko hamwe na Pragmatic Reba
Isoko ryuzuyemo imishinga isaba ubushobozi. Itandukaniro riri mubiganiro bya tekiniki. Iyo ndebye inyuma yabatanga isoko, imyaka 30 muruganda, nkuko QSY ibivuga, ibimenyetso bashobora kuba barabonye ibintu byinshi hamwe nubwihindurize. Bishatse kuvuga ko bashobora kuba barabonye imishinga 17-4 yakoze nindi itayikoze.
Ibyo bavuga gukorana nabo cobalt na nikel ni porokisi nziza. Niba bashoboye gukora isuka no gutunganya ibyo bintu bya superalloys, 17-4 nibyiza mumagare yabo ya metallurgical. Ikibazo gikunze kuba muburyo bwo gukora umusaruro, ntabwo gukora icyitegererezo cyiza.
Mu kurangiza, kwerekana '17 4 gushora imari 'ni intangiriro yikiganiro, ntabwo iherezo. Ihuza ibintu byoroshye kandi inzira yoroshye. Intsinzi ishingiye ku gusobanukirwa ko ihuriro-ibibazo bitemba amazi, kugenzura ubushyuhe budasubirwaho, hamwe nuburinganire. Shaka ubwo bufatanye neza hamwe nu iduka ryumvikana neza, kandi inzira itanga ibice bidashoboka gukora ubundi buryo. Wibeshye, kandi usigaye ufite ibicuruzwa bihenze cyane, bigoye cyane.
