Loj-inch seamless yeeb nkabthermal molding txheej txheem

Thermal forming manufacturing process, nrog rau qhov loj-inch seamless kub dov thiab kub extrusion ntawm ob txoj kev, lub qub yog tsuas yog siv nyob rau hauv zus tau tej cov yeeb nkab sib txuas, uas siv seamless puas yeeb nkab ntau lawm.

Rolling yog ib txoj kev ib txwm ua ntawm kev npaj loj-inch seamless steel yeeb nkab.Kub dov hauv cov khoom siv vuam siab, yog tias qhov deformation loj txaus, lub siab tawm los ntawm cov yob ntawm cov hlau yuav ua rau cov oxide zaj duab xis puas, cov atomic nto nyob rau hauv kev sib cuag, kom ob qhov chaw yog welded ua ke.Rolling disadvantages yog:

Qhov zoo ntawm dov: cov khoom tsim tau zoo, zoo zoo, tus nqi qis, thiab tuaj yeem txuag tau ntau qhov hnav thiab tsim kua muag ntawm cov khoom siv hlau, thiab yog li ntawd yog qhov siv dav heev ntawm cov khoom siv sib xyaw ua ke.Rolling composite sheet combining 90% ntawm tag nrho cov phaj sib xyaw, thiab feem ntau yog siv rau cov yeeb nkab phab ntsa thickness tsawg dua 32 hli ntawm kev ua.

Qhov tsis zoo ntawm dov: kev nqis peev ib zaug, tab sis kuj muaj ntau cov khoom sib xyaw ua ke tsis tuaj yeem ua tiav los ntawm dov complex.Tam sim no yog cov cuab yeej siv dav tshaj plaws rau kev siv cov dov steel, stainless hlau puas yeeb nkab sib txuas raug tsim.

Kub extrusion feem ntau yog ua rau ob-hlau raj, hu ua kev sib xyaw extrusion (coextrude).Coextrusion tam sim no yog txoj hauv kev zoo tshaj plaws rau kev tsim cov hlau tsis muaj steel thiab siab nickel alloy seamless composite raj, Nyiv Steel ua los ntawm txoj kev no 8in (203.2mm) hauv qab bimetallic composite yeeb nkab.Nws yog qhov loj-inch sib xyaw uas muaj ob lossis ntau dua hlau dawb yog rhuab mus txog 1200℃, thiab ces extruded los ntawm ib qho chaw annular tsim los ntawm pwm thiab mandrel.Thaum extrusion billet cross-section raug txo mus rau 10: 1, siab extrusion siab thiab kub ntawm lub interface tsim "siab vuam" vuam nyhuv, txhawb lub ceev thiab dav diffusion ntawm lub interface ntawm kev sib txuas ua ke kom ua tiav metallurgical bonding interface.Ua ntej extrusion composite raj tsim txoj kev, muaj peb yam: forging billet tho thiab loj los ntawm kub extrusion tau;ncaj qha centrifugal spin casting;corrosion resistant hmoov hais.Muaj ob cov khoom siv hlau siv sab hauv thiab sab nraud cov hmoov, hu ua "NUVAL" thev naus laus zis, tuaj yeem tsim cov alloys tshiab, tab sis tus nqi siab dhau rau kev npaj hmoov.Qhov tsis zoo ntawm Coextrusion yog:

Qhov zoo ntawm kub extrusion: Lub interface yog metallurgically bonded;cov rog koom nrog hauv cov txheej txheem extrusion yog kev ntxhov siab tag nrho, nws yog qhov tshwj xeeb zoo rau kev ua haujlwm kub, kev ua haujlwm siab ntawm cov hlau tsis muaj plasticity ntawm cov hlau.

Disadvantages ntawm kub extrusion: Raws li txiav txim los ntawm cov txheej txheem extrusion ua ke nrog ib tug luv luv diffusion interface ntsiab, feem ntau yog vim muaj cov oxide zaj duab xis tau cuam tshuam, kom deb li deb txwv rau cov composite extrusion composite carbon steel, stainless hlau thiab siab nickel alloys ntawm .Nws tau muab sau tseg tias me me deformation tsis kam ntawm kub extrusion, tso cai rau ib tug loj degree ntawm deformation ntawm txhua tus, uas ua rau ntau dua nto roughness, thiab yog li ntawd kuj yuav tsum tau ntxiv txias dov lub kub extrusion (los yog kos duab) ntawm txoj kev ntawm kev tsim ib tug puas yeeb nkab. .
