Cov phab ntsa tsis sib luag ntawm cov raj seamless (SMLS) feem ntau yog tshwm sim nyob rau hauv qhov tshwm sim ntawm cov phab ntsa tsis sib luag ntawm cov kauv cov duab, cov phab ntsa tuab ntawm txoj kab ncaj nraim, thiab cov phab ntsa tuab thiab nyias ntawm lub taub hau thiab tus Tsov tus tw. Kev cuam tshuam ntawm cov txheej txheem txuas txuas txuas ntxiv ntawm kev hloov pauv ntawm cov raj seamless yog qhov tseem ceeb ua rau cov phab ntsa tsis sib xws ntawm cov kav dej tiav. Tshwj xeeb:
1. Lub kauv phab ntsa thickness ntawm lub seamless raj yog tsis sib xws

Cov laj thawj yog: 1) Cov phab ntsa tuab ntawm cov yeeb nkab steel seamless tsis sib npaug vim qhov kev hloov kho xws li qhov tsis raug dov qhov nruab nrab ntawm lub tshuab tho, lub kaum sab xis ntawm ob lub yob, los yog txo qis me me ua ntej lub ntsaws, thiab feem ntau yog muab faib rau hauv ib lub kauv zoo raws li tag nrho ntev ntawm cov yeeb nkab steel. .
2) Thaum lub sij hawm dov, qhov nruab nrab ntawm cov chais tau qhib ntxov dhau, cov chais nruab nrab tsis tau hloov kho kom raug, thiab cov phab ntsa tuab tsis sib npaug vim qhov kev vibration ntawm lub ejector pas nrig, uas feem ntau faib rau hauv cov duab kauv raws tag nrho ntev. ntawm cov yeeb nkab steel.

Ntsuas:
1) Kho cov dov qhov nruab nrab ntawm lub tshuab tho kom lub kaum sab xis ntawm ob lub yob sib npaug, thiab kho cov dov zeb raws li qhov tsis tau muab rau hauv lub rooj dov.

2) Rau qhov thib ob, kho lub sijhawm qhib ntawm cov menyuam qhov chaw nruab nrab raws li qhov kev tawm ntawm lub raj capillary, thiab tsis txhob qhib qhov chaw nruab nrab ntawm cov menyuam thaum ntxov thaum lub sijhawm dov los tiv thaiv lub ejector pas nrig los ntawm kev co, ua rau cov phab ntsa tsis sib xws. thickness ntawm seamless steel yeeb nkab. Qhov qhib qhov chaw ntawm cov menyuam qhov chaw nruab nrab yuav tsum tau kho kom zoo raws li qhov kev hloov pauv ntawm txoj kab uas hla ntawm lub capillary, thiab qhov ntaus nqi ntawm lub capillary yuav tsum tau muab coj los xav.
2. Cov phab ntsa linear thickness ntawm seamless raj yog tsis sib xws

Ua rau:
1) Kev kho qhov siab ntawm mandrel pre-piercing eeb tsis tsim nyog. Thaum lub mandrel yog pre-piercing, nws tiv tauj lub capillary ntawm ib sab, ua rau qhov kub ntawm capillary poob sai heev rau ntawm qhov chaw tiv tauj, ua rau cov phab ntsa thickness ntawm seamless steel yeeb nkab los yog txawm concave defect.
2) Qhov sib txawv ntawm qhov nruam dov yob yog me me lossis loj dhau.
3) Kev sib txawv ntawm cov kab nruab nrab ntawm lub tshuab dov.
4) Qhov tsis sib xws ntawm ib leeg thiab ob chav racks yuav ua rau cov kab sib txawv ntawm cov yeeb nkab steel yog ultra-thin (ultra-tick) nyob rau hauv cov kev taw qhia ntawm ib lub khib thiab ultra-thick (ultra-thin) nyob rau hauv cov kev taw qhia ntawm ob chav racks.
5) Kev ruaj ntseg kev txiav txim siab tau tawg, thiab qhov sib txawv ntawm sab hauv thiab sab nraud sib txawv yog qhov loj, uas yuav ua rau kev sib txawv ntawm cov yeeb nkab ncaj ntawm cov yeeb nkab ncaj.
6) Kev hloov kho tsis tu ncua ntawm cov dov tsis tu ncua, stacking steel thiab kos duab dov yuav ua rau cov phab ntsa tsis sib xws hauv txoj kab ncaj nraim.

Ntsuas:
1) Kho qhov siab ntawm mandrel pre-piercing eeb los xyuas kom meej qhov chaw ntawm lub mandrel thiab capillary.
2) Thaum hloov hom dhau thiab dov specification, yob qhov sib txawv yuav tsum tau ntsuas kom qhov tseeb yob qhov sib txawv raws li lub rooj dov.
3) Kho qhov chaw dov kab nrog cov khoom siv kho qhov muag, thiab cov kab nruab nrab ntawm cov dov zeb yuav tsum raug kho thaum lub sij hawm kho txhua xyoo.
4) Lub sijhawm hloov cov thav duab nrog cov tshuaj khib nyiab pov tseg, ntsuas qhov khoob hauv thiab sab nraud ntawm cov yob txuas ntxiv, thiab hloov lawv raws sijhawm yog tias muaj teeb meem.
5) Thaum nruam dov, hlau kos duab thiab stacking yuav tsum tau zam.

3. Lub phab ntsa thickness ntawm seamless raj taub hau thiab tus Tsov tus tw yog tsis sib xws
Ua rau:
1) Qhov txiav txoj kab nqes thiab curvature ntawm lub hauv ntej kawg ntawm lub raj khoob yog loj heev, thiab qhov nruab nrab ntawm lub raj tsis muaj qhov tsis raug, uas yuav yooj yim ua rau phab ntsa tuab ntawm cov yeeb nkab steel taub hau tsis sib xws.
2) Thaum tho, lub elongation coefficient loj heev, yob ceev yog siab dhau, thiab dov tsis ruaj khov.
3) Cov hlau tsis ruaj khov uas cuam tshuam los ntawm tus piercer tuaj yeem yooj yim ua rau cov phab ntsa tsis sib xws ntawm qhov kawg ntawm lub raj capillary.

Ntsuas:
1) Txheeb xyuas qhov zoo ntawm lub raj khoob kom tiv thaiv lub hauv ntej kawg ntawm lub raj khoob los ntawm kev txiav inclination thiab txo qhov loj, thiab qhov chaw nruab nrab yuav tsum raug kho thaum hloov hom dhau los lossis kho dua.
2) Siv cov tho qhov qis dua kom ntseeg tau tias qhov ruaj khov ntawm dov thiab qhov sib xws ntawm cov phab ntsa capillary thickness. Thaum lub yob ceev tau hloov kho, daim ntawv qhia kev sib txuam kuj raug kho raws li.
3) Ua tib zoo saib xyuas cov txheej txheem ntawm kev siv cov ntawv qhia phaj thiab nce kev tshuaj xyuas ntawm cov ntawv qhia phaj bolts, txo qhov ntau ntawm kev txav ntawm cov ntawv qhia phaj thaum lub sij hawm steel dov, thiab xyuas kom ruaj khov ntawm cov hlau ntuav.
