Pachave nekusadzisika kurasikirwa mukushandiswa kwesimbi kupfura uye grit, uye pachava nekurasikirwa kwakasiyana nekuda kwenzira yekushandisa uye zvinhu zvakasiyana zvekushandisa. Saka iwe unoziva here kuti hupenyu hwebasa hwemapfuti esimbi nehurema hwakasiyana hwakasiyanawo?
Kazhinji, kuoma kwesimbi inopfurwa inoenderana nekumhanya kwayo kwekuchenesa, ndiko kuti, iyo yakakwirira kuoma kwesimbi inopfurwa, inokurumidza kukurumidza kuchenesa kwayo, zvinoreva zvakare kuti kushandiswa kwesimbi kupfura kuchava kukuru uye hupenyu hwebasa. ichava pfupi.
Simbi yepfuti ine matatu akaomesesa akasiyana: P (45-51HRC), H (60-68HRC), L (50-55HRC). Isu tinotora P kuoma uye H kuoma semienzaniso yekuenzanisa:
P kuomarara kazhinji HRC45 ~ 51, kugadzira mamwe simbi dzakaomarara, inogona kuwedzera kuomarara kusvika kuHRC57 ~ 62. Vane kusimba kwakanaka, hupenyu hwesevhisi hurefu kupfuura H kuoma, uye huwandu hwakawanda hwekushandisa.
H kuomarara ndeye HRC60-68, rudzi urwu rwesimbi kupfurwa kuoma kwakakwira, firiji ine brittle, iri nyore kupaza, hupenyu hupfupi, application haina kupararira zvakanyanya. Inonyanya kushandiswa munzvimbo dzinoda yakanyanya kupfura peening intensity.
Naizvozvo, ruzhinji rwevatengi vanotenga mapfuti esimbi ane P kuomarara.
Maererano nemuedzo, tinoona kuti nhamba yezvikamu zvesimbi yakapfurwa neP kuoma kwakakwirira kudarika H kuoma, H kuoma kunosvika ka2300, uye P kuomarara kutenderera kunogona kusvika 2600 nguva. Wakamboedza macycle mangani?
