12Cr1MoVG yakakwira kudzvinyirirwa alloy simbi pombi yemhando yekusimbisa
Iyo nzvimbo yekushandisa ye12Cr1MoVG alloy pombi inowedzerwa kuti ipe nzvimbo yakakura yekusimudzira indasitiri. Zvinoenderana nekutsvagisa kwe12Cr1MoVG alloy pombi bazi reChina Special Steel Association, kudiwa kwepamusoro-kudzvanywa 12Cr1MoVG alloy pombi kureba muChina kuchawedzera ne10-12% pagore mune ramangwana. Classification ye12Cr1MoVG alloy pombi.
Mukana mukuru we12Cr1MoVG alloy pombi ndeyekuti inogona kudzokororwazve 100%, izvo zvinoenderana nehurongwa hwenyika hwekuchengetedza kwezvakatipoteredza, kuchengetedza simba uye kuchengetedza zviwanikwa. Mutemo wenyika unokurudzira kuwedzera kwendima yekushandiswa kwepamusoro-kudzvinyirira 12Cr1MoVG alloy pipe.
Nekuda kwemaitiro akasiyana ekugadzira, yakakamurwa kuita inopisa yakakungurutswa (yakasimudzwa) isina musono pombi uye inotonhora inodhonzwa (yakakungurutswa) isina musono simbi pombi. Cold yakadhirowewa (yakakungurutswa) pombi inokamurwa kuita denderedzwa pombi uye yakakosha-yakaumbwa pombi.
a. Process flow overview
Pombi yesimbi inopisa yakamonereka (yakasimudzwa) isina musono: chubhu isina chinhu → kudziyisa → perforation → matatu roll cross rolling, kuramba achiumburuka kana extrusion → kubviswa pombi → saizi (kana kuderedza) → kutonhora → chubhu isina chinhu → kutwasanudza → hydrostatic bvunzo (kana kuona kukanganisa) → kumaka → kuchengetera zvinhu.
Inotonhora inodhonzwa (yakakungurutswa) isina musono pombi yesimbi: yakatenderera chubhu isina chinhu → kudziyisa → perforation → musoro → annealing → pickling → kuzora (copper plating) → yakawanda kupfuura inotonhora kudhirowa (inotonhora kukunguruka) → isina chinhu chubhu → kupisa kupisa → kutwasanura → hydrostatic test (chikanganiso kuona) → kumaka → kuchengetera zvinhu.
