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-yakakungurutswa (yakasimudzwa, yakawedzerwa) uye inotonhora-inodhonzwa (yakakungurutswa) isina musono pombi yakagadzirwa nesimbi isina tsvina inoshandiswa mumakemikari, peturu, machira, ekurapa, chikafu, muchina uye mamwe maindasitiri, mapombi asingadziviriri uye zvikamu zvemukati.

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

Seamless simbi pombi

Nemhaka yekugadzira kwayo kwakasiyana, yakakamurwa kuita inopisa yakakungurutswa (extruded) isina musono chubhu uye inotonhora inoswededzwa (yakakungurutswa) isina musono simbi chubhu two kinds.Cold-inodhonzwa (yakakungurutswa) pombi inokamurwa kuita denderedzwa pombi uye yakakosha-yakaumbwa pombi marudzi maviri.

A. Overview ye process flow

Kupisa kutenderedza (extruded seamless simbi chubhu) : round chubhu billet → kudziyisa → perforation → matatu-roll cross rolling, inoramba ichikunguruka kana extrusion → chubhu kubviswa → saizi (kana kuderedza) → kutonhora → isina chinhu chubhu → kutwasanura → mvura yekumanikidza bvunzo (kana kuona kukanganisa) → kumaka → kuchengetedza.

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