1 .Kusuma muchidimbu pombi yekugadzira

Seamless pombi yegadziriro (GB/T8162-2008) inoshandiswa kune yakajairika chimiro uye mechanical chimiro chepombi isina musono.Seamless simbi chubhu inokamurwa kuva zvakasiyana-siyana kushandiswa.

Simbi isina musono pombi yechimiro (GB/T14975-2002) inopisa-yakatenderedzwa (yakasimudzwa, yakawedzerwa) uye inotonhora-yakadhonzwa (yakakungurutswa) isina musono pombi yakagadzirwa nesimbi isina tsvina inoshandiswa mumakemikari, peturu, machira, kurapwa, chikafu, muchina uye. mamwe maindasitiri, mapaipi asingadziviriri uye maumbirwo ezvikamu uye zvikamu.

GB/T8162-2008 (isina musono pombi yechimiro) inonyanya kushandiswa kune yakajairika chimiro uye michina chimiro.Its mumiriri zvinhu (mhando): kabhoni simbi 20, 45 simbi, Q235, alloy simbi Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo. , 42CrMo uye zvichingodaro.

Seamless simbi pombi

Nemhaka yekugadzirwa kwayo kwakasiyana, yakakamurwa kuita inopisa yakakungurutswa (extruded) seamless simbi chubhu uye inotonhora inoswededzwa (yakakungurutswa) isina musono simbi chubhu mhando mbiri.Inotonhora-inodhonzwa (yakakungurutswa) pombi inokamurwa kuita denderedzwa pombi uye yakakosha-yakaumbwa pombi mbiri. marudzi.

A. Overview ye process flow

Kupisa kukungurutsira (yakawedzera musono chubhu yesimbi) : yakatenderera chubhu billet → kudziyisa → perforation → matatu-roll muchinjiko kukunguruka, kuenderera kutenderera kana extrusion → chubhu kubviswa → saizi (kana kuderedza) → kutonhora → isina chinhu chubhu → kutwasanura → mvura yekumanikidza bvunzo (kana kuremara kuona) → kumaka → kuchengetedza.

Kudhirowa kunotonhora (kukunguruka) isina musono chubhu yesimbi: round chubhu billet → kudziyisa → perforation → musoro → annealing → pickling → kuzora (copper plating) → yakawanda-inopfuura inotonhora kudhirowa (inotonhora inokunguruka) → isina chubhu → kupisa kupisa → kutwasanura → mvura yekumanikidza bvunzo (kuona kukanganisa) → kumaka → kuchengetedza.
