Tafsiri za uzalishaji
Chini ya shinikizo katikati ya boiler bomba kwa chuma ingot au kubeba ngumu chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma Seamless chuma bomba ina nafasi muhimu katika viwanda vya chuma bomba nchini wetu. Kulingana na takwimu zisizo kamili, bomba la sasa la seamless nchini China
Makampuni ya uzalishaji zaidi ya 240, mashine ya chuma ya bomba ya seamless zaidi ya seti 250, uwezo wa uzalishaji wa kila mwaka zaidi ya tani milioni 4.5. Kutokana na caliber, <φ76, asilimia 35, <φ159-650, asilimia 25. Kutoka kwa aina
|
Angalia, matumizi ya jumla ya bomba tani milioni 1.9, ambayo ni asilimia 54; bomba mafuta tani 760,000, asilimia 5.7; Msingi wa hydraulic, ubombo wa usahihi wa tani 150,000, ikiwa ni asilimia 4.3; Pua bomba, kubeba bomba, magari bomba jumla ya tani 50,000,asilimia ya 1.4. |

| Vifaa vya chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma Chuma billet kutumwa ndani ya kilasi cha kuchyuka | Joto ni karibu 1200 ° C. Mafuta ni hidrojeni au acetylene. Udhibiti wa joto ndani ya tanuru ni suala muhimu. Baada ya kupitia mashine ya kupiga shinikizo, chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma. Mashine ya kawaida zaidi ya punching ni cone roller punching mashine, | Mashine hii ya perforation ufanisi wa juu, ubora wa bidhaa nzuri, ukubwa mkubwa wa kupanua perforation, inaweza kuvaa aina mbalimbali za chuma. Baada ya perforation, chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chu Baada ya kushinikiza kuondolewa. Diameter Machine kwa njia ya cone drill juu | Kuzunguka kwa kasi katika chuma embryo perforation, kuunda chuma bomba. Diameter ya ndani ya bomba la chuma inaamuliwa na urefu wa diameter ya nje ya drill ya makini ya kupima. Baada ya chuma bomba kupitia diameter, kuingia katika mnara baridi, baridi kupitia maji spray, chuma bomba baada ya baridi, itakuwa straightened. chuma bomba moja kwa moja |
| Baadaye kupitishwa kwa conveyor belt kwa chuma detector (au majaribio ya shinikizo la maji) kwa ajili ya uchunguzi wa ndani. Kama chuma chuma ndani ya bomba kuna vifungu, vifuvu na matatizo mengine, itakuwa kugundua. Baada ya ukaguzi wa ubora wa bomba la chuma pia lazima kupitia uchaguzi mkali wa mikono. Mafuta baada ya uchunguzi wa ubora wa chuma | Nambari ya rangi, vipimo, idadi ya uzalishaji, nk. na kuingizwa kwenye ghala ya kuhifadhi. | Chini ya shinikizo la kati boiler bomba Spot | （GB3087-2008） |
