Mark Ford, maneja wekuvandudza kwekugadzira kuAFG Industries, Inc., anotsanangura:
Girazi rinodziya rine simba rakapetwa kana pane "rakajairika," kana annealed, girazi. Uye kusiyana negirazi rakavharirwa, iro rinogona kupwanyika kuita zvidimbu zvidimbu kana girazi rakapwanyika rinotsemuka kuita zvidimbu zvidiki, zvisingakuvadzi. Nekuda kweizvozvo, girazi rinodziya rinoshandiswa munzvimbo idzodzo uko kuchengetedzwa kwevanhu inyaya. Zvikumbiro zvinosanganisira mahwindo epadivi neekumashure mumotokari, magonhi ekupinda, eshawa nematabhu akavharirwa, matare ebhora reracquetball, fenicha yepapatio, ovheni dzemicrowave uye matenga edenga.
Kuti ugadzirire girazi rekupisa, rinofanira kutanga ratemwa kusvika pakukura kwaunoda. (Kuderedza simba kana kukanganisa kwechigadzirwa kunogona kuitika kana chero maitiro ekugadzira, akadai sekucheka kana edging, anoitika mushure mekupisa kupisa.) Girazi rinozoongororwa nokuda kwekusakwana kunogona kukonzera kuputsika pane imwe nhanho panguva yekupisa. Abrasive senge sandpaper inotora mipendero yakapinza kubva pagirazi, iyo inozosukwa.
SANGANO
Zvadaro, girazi rinotanga nzira yekurapa kupisa iyo inofamba nayo kuburikidza nehovheni inopisa, ingave mubatch kana kuenderera mberi kwekudya. Ovheni inopisa girazi kusvika kune tembiricha inodarika 600 degrees Celsius. (The industry standard is 620 degrees Celsius.) Girazi rinobva raita high-pressure cooling procedure inonzi "quenching." Mukati mekuita uku, uko kunotora masekonzi chete, mhepo ine simba guru inoputika pamusoro pegirazi kubva munhevedzano yemhuno munzvimbo dzakasiyana-siyana. Kudzima kunotonhora kunze kwegirazi nekukurumidza zvakanyanya kupfuura pakati. Sezvo pakati pegirazi inotonhora, inoedza kudhonzera kumashure kubva kunze kwekunze. Nekuda kweizvozvo, iyo yepakati inoramba iri mukukakavadzana, uye nzvimbo dzekunze dzinopinda mukumanikidzana, izvo zvinopa girazi rine hasha simba rayo.
Girazi mukunetsana rinotsemuka zvakapetwa kashanu zviri nyore pane zvarinoita mukumanikidzana. Girazi rakanamirwa richatsemuka pa6,000 pounds per square inch (psi). Girazi rakapfava, zvinoenderana nehurongwa hwemubatanidzwa, hunofanirwa kuve nekudzvanywa kwepamusoro kwe10,000 psi kana kupfuura; kazhinji inotyora kusvika pa24,000 psi.
Imwe nzira yekugadzira girazi rinodziya ndeyekupisa makemikari, umo makemikoro akasiyana-siyana anochinjana maion pamusoro pegirazi kuti agadzire kudzvanywa. Asi nekuti nzira iyi inodhura zvakanyanya kupfuura kushandisa hovhoni dzekudziya uye yekudzima, haishandiswe zvakanyanya.
