Kuyoba khona ukulahlekelwa nakanjani ekusetshenzisweni kwe-steel shot kanye ne-grit, futhi kuzoba nokulahlekelwa okuhlukile ngenxa yendlela yokusetshenziswa kanye nezinto ezihlukene ezisetshenziswayo. Ngakho-ke uyazi ukuthi impilo yesevisi yesibhamu sensimbi enobunzima obuhlukile nayo ihlukile?
Ngokuvamile, ukuqina kokudubula kwensimbi kuhambisana nesivinini sayo sokuhlanza, okungukuthi, ukuphakama kokuqina kwensimbi, isivinini sokuhlanza sishesha, okusho futhi ukuthi ukusetshenziswa kwesibhamu sensimbi kuzoba kukhulu kanye nempilo yesevisi. izoba mfishane.
Ukudubula kwensimbi kunobunzima obuthathu obuhlukene: P (45-51HRC), H (60-68HRC), L (50-55HRC). Sithatha ubulukhuni buka-P no-H njengezibonelo zokuqhathanisa:
Ubulukhuni be-P ngokuvamile buyi-HRC45 ~ 51, ukucubungula ezinye izinsimbi eziqinile uma kuqhathaniswa, kungandisa ubulukhuni bufike ku-HRC57 ~ 62. Zinokuqina okuhle, impilo yesevisi ende kunobulukhuni be-H, kanye nezinhlobonhlobo zezinhlelo zokusebenza.
Ukuqina kwe-H yi-HRC60-68, lolu hlobo lokuqina kokudubula kwensimbi kuphakeme, isiqandisi sinobuthi kakhulu, kulula kakhulu ukuphuka, ukuphila okufushane, isicelo asibanzi kakhulu. Isetshenziswa kakhulu ezindaweni ezidinga ukushuba okuphezulu kokuchama.
Ngakho-ke, iningi lamakhasimende lithenga amashothi ensimbi anobulukhuni be-P.
Ngokusho kokuhlolwa, sithola ukuthi inani lemijikelezo yensimbi edutshulwa ngobulukhuni be-P iphakeme kunobulukhuni be-H, ukuqina kwe-H cishe izikhathi ezingu-2300, kanti umjikelezo wokuqina we-P ungafinyelela izikhathi ezingu-2600. Mingaki imijikelezo oyihlolile?
