Foornada Biraha ee Markabka

Waxyaabaha qaybtan been abuurka ah:

14CrNi3MoV (921D), oo ku habboon alwaaxyada birta ah ee dhumucdeedu aan ka badnayn 130mm ee loo isticmaalo maraakiibta.

Habka wax-soo-saarka:

Birta been abuurka ah waa in lagu dhalaaliyaa iyadoo la isticmaalayo foornada korontada ku shaqeysa iyo habka dib-u-dhajinta korantada, ama habab kale oo ay ansixisay dhinaca dalabka.Birtu waa in ay martaa deoxidation ku filan iyo hababka sifaynta badarka.Markaad si toos ah u been abuurto miskaha qayb been abuur ah, saamiga been abuurka ee jidhka ugu weyn ee qaybta waa in aanu ka yarayn 3.0.Saamiga been-abuurka ee qaybaha fidsan, flanges, iyo qaybaha kale ee la fidiyay ee qaybta been-abuurka ah waa in aanay ka yarayn 1.5.Marka la been abuurayo billet-ka qayb been abuur ah, saamiga been-abuurka ee jidhka ugu weyn ee qaybtu waa in aanu ka yarayn 1.5, saamiga been-abuurka ee qaybaha soo baxayaa waa in aanu ka yarayn 1.3.Qaybaha been abuurka ah ee laga sameeyay xashiishka ama xashiishka la been abuurtay waa in lagu sameeyaa daawaynta fuuq-baxa ku filan.Alxanka birta loo isticmaalo soo saarista qaybo been abuur ah lama ogola.

Xaaladda keenista:

Qaybta been abuurka ah waa in lagu bixiyaa xaalad demisay oo xanaaqsan ka dib marka la caadiyeeyo daawaynta ka hor.Habka lagu taliyay waa (890-910) ° C caadi ahaan + (860-880) ° C deminta + (620-630) ° C xanaaq.Haddii dhumucda qaybta been abuurka ah ay dhaafto 130mm, waa in ay martaa xanaaq ka dib mashiinka qallafsan.Qaybaha la foorjaray ee la foorjaray waa in aanay marin ciribtirka walaaca iyada oo aan oggolaansho laga helin dhinaca dalabka.

Guryaha makaanikada:

Ka dib daaweynta kuleylka, sifooyinka farsamada ee qaybta been-abuurka ah waa inay u hoggaansamaan qeexitaannada khuseeya.Ugu yaraan tijaabooyinka saamaynta heerkulka -20°C, -40°C, -60°C, -80°C, iyo -100°C waa in la sameeyaa, waana in la sawiraa saamaynta dhammaystiran ee qalooca heerkulka tamarta.

Ku darida aan biraha ahayn iyo cabbirka hadhuudhka:

Qaybaha been abuurka ah ee laga sameeyay godadka waa in ay lahaadaan qiyaasta cabbirka badarka oo aan ka yarayn 5.0.Heerka nooca A ee ku jira birta waa inuusan dhaafin 1.5, heerka ku darida nooca R waa inuusan dhaafin 2.5, iyadoo wadarta labadaba aysan ka badneyn 3.5.

Tayada dusha sare:

Qaybaha la been-abuuray waa in aanay yeelan cillado dusha sare ka muuqda sida dildilaacyada, laalaabyada, godadka yaraanshaha, nabarrada, ama ku darida shisheeyaha aan biraha ahayn.Cilladaha dusha sare waxaa lagu sixi karaa xoqid, xoqid, wax lagu shiidi karo giraangiraha, ama hababka makiinada, iyadoo la hubinayo gunno ku filan oo lagu dhammeeyo hagaajinta ka dib.
