Iyo Rockwell kuomarara kwesimbi yakavharwa plain carbon steel inowanzoita 55+-3, uye kuomarara kwesimbi isina kuvharwa inomonerwa nechando inomonereka inodarika makumi masere. ye100-2000mm; ose ari maviri anogadzirwa netambo yakamonerwa inopisa kana ndiro yesimbi. .
CRS ndiyo chidimbu cheChirungu inotonhorera yakakungurutswa simbi, kureva, inotonhora yakakungurutswa simbi. Rinoreva kukunguruka kwesimbi. Semuenzaniso, q235 yakajairwa kabhoni simbi ndiro inogona kutonhora yakakungurutswa, uye 10# simbi ndiro inogona zvakare kutonhora yakakungurutswa. Kuoma kwayo kunogona kunge kuri pachiyero chinoenderana zvinoenderana negiredhi resimbi rinoshandiswa. .
Ndeipi giredhi reinotonhora-yakatenderedzwa pepa rakaoma kupfuura spcc? .
Cold-rolled sheet ndiyo chidimbu cheakajairwa kabhoni simbi inotonhora-yakakungurutswa pepa, inozivikanwawo seinotonhora-yakakungurutswa shiti, rinowanzozivikanwa seinotonhora-yakakungurutswa pepa, uye dzimwe nguva yakanyorwa zvisirizvo seinotonhora-yakakungurutswa pepa. Iyo inotonhora ndiro inogadzirwa neyakajairwa kabhoni structural simbi inopisa-yakakungurutswa simbi tambo, iyo inowedzera kutonhora-inokungurutswa kuita simbi nekukora isingasviki 4mm. .
Iyo inotonhora-yakatenderedzwa pepa yakakamurwa kuita: 1/8 yakaoma, 1/4 yakaoma, 1/2 yakaoma uye yakazara yakaoma mamiriro. Panowanzove nezvikamu zviviri zvikuru zvekuomarara kukosha: HRB (Rockwell) HV (Vickers) sezvizvi: Chiratidzo chinosiyanisa chemhando HRB (Rockwell) HV (Vickers) 1/8 yakaoma. .
Pickling ndiro ndiro inopisa-yakakungurutswa iyo inoiswa pasi pekuita senge dephosphorization (kubvisa ngura, zvisaririra, nezvimwewo, inogadzirwa panguva yekupisa-kukungurukira) uye mamwe maitiro ekunyungudutsa pamusoro kuti uwane ndiro yesimbi ine basa riri nani pane kupisa. -yakakunguruka pamusoro. Inogona kuonekwa kubva pakugadzira kwayo kuti kuoma kwayo kunopisa kunoputirwa negiredhi rimwechete. .
Hapana mutsauko mukuoma kwepasi pakati pekutonhora-yakakungurutswa nemarara. Nokuti nzvimbo yakavharidzirwa inongoputirwa nemucheka we zinc kubva kune mashoma ma microns kusvika ku 20 microns pane substrate. Ma substrates anowanzo kutonhora-akakungurutswa uye anopisa-akakungurutswa. Kuomarara kunonyanya kuenderana negiredhi rezvinhu, uye mamakisi anosiyana. .
Tora DC01, DC03 semuenzaniso. DC01 muganhu wepamusoro wekusimba kwegoho 280 DC03 muganhu wepamusoro wegoho simba 240 , dc06+ze, dzinoenderana nebepa rinotonhora, nhamba inomiririra giredhi rekutsika, uye nhamba huru ndiyo.
Pepa rinotonhora-rakakungurutswa rakagadzirwa neyakavhuvhuta-inopisa coil seyakabikwa, yakakungurutswa pakamuri tembiricha pazasi petembiricha recrystallization, uye kuoma kwayo kunosvika 150HV. Mashizha emuchina wekuveura anowanzo kugadzirwa nesimbi yemidziyo, nekuoma kweHRC55 ~ 58 °, inogona kucheka mazhinji awo.
