Hlau kav feem ntau muab faib ua seamless steel kav thiab welded steel kav raws li txoj kev ntau lawm. Lub sij hawm no peb tsuas yog qhia welded steel kav, uas yog, seamed steel kav. Kev tsim khoom yog khoov thiab yob cov yeeb nkab blanks (steel plates thiab steel strips) rau hauv qhov yuav tsum tau ua los ntawm ntau txoj kev tsim. Piv nrog seamless steel yeeb nkab welded yeeb nkab, nws muaj cov khoom siab precision, tshwj xeeb tshaj yog cov phab ntsa thickness precision, yooj yim cov cuab yeej tseem ceeb, me me hneev taw, Cov yam ntxwv ntawm kev ua haujlwm tsis tu ncua thiab hloov tau yooj yim hauv ntau lawm, cov yeeb nkab welded yuav tsum muab faib ua peb pawg: kauv submerged. arc welded yeeb nkab, ncaj seam ob-sided submerged arc welded yeeb nkab, thiab ncaj seam siab zaus kuj welded yeeb nkab.

1. Kauv submerged arc welded yeeb nkab

Cov ntaub ntawv raw ntawm kauv steel yeeb nkab (SSAW) yog strip coil, vuam hlau thiab flux. Ua ntej tsim, lub sawb undergoes leveling, ntug trimming, ntug planing, deg tu thiab conveying thiab pre-bending kho. Lub vuam qhov sib txawv tswj cov cuab yeej siv los xyuas kom meej tias qhov sib txawv vuam ua tau raws li qhov yuav tsum tau ua ntawm vuam Nws yuav tsum nruj me ntsis tswj cov yeeb nkab txoj kab uas hla, misalignment thiab vuam qhov sib txawv. Tom qab txiav rau hauv ib lub yeeb nkab steel, thawj peb cov kav dej ntawm txhua pawg yuav tsum tau ua raws li kev tshuaj xyuas thawj zaug los xyuas cov khoom siv, tshuaj lom neeg muaj pes tsawg leeg, fusion xeev thiab qhov chaw ntawm lub vuam. Tom qab kev soj ntsuam zoo thiab tsis muaj kev puas tsuaj los xyuas kom meej tias cov yeeb nkab ua cov txheej txheem tsim nyog, nws tuaj yeem raug muab tso rau hauv kev tsim khoom.

2. Ncaj seam submerged arc welded yeeb nkab

Feem ntau hais lus, ncaj seam submerged arc welded yeeb nkab (LSAW) yog ua los ntawm steel phaj. Tom qab cov txheej txheem sib txawv, cov yeeb nkab welded yog tsim los ntawm ob tog submerged arc vuam thiab tom qab vuam nthuav dav. Txoj kev tsim ntawm txoj hlua ncaj nraim submerged arc welded yeeb nkab yog UO (UOE). , RB (RBE), JCO (JCOE), thiab lwm yam.

UOE ncaj seam submerged arc welded yeeb nkab txoj kev:

Muaj peb txoj hauv kev ua haujlwm hauv UOE LSAW steel yeeb nkab txoj kev: steel phaj pre-bending, U forming thiab O forming. Txhua txheej txheem siv cov xovxwm tshwj xeeb los ua kom tiav cov khoom ua ntej khoov, U sib sau thiab O sib sau ntawm ntug ntawm cov hlau phaj tig. Peb txheej txheem, cov hlau phaj yog deformed rau hauv lub voj voog, JCOE ncaj seam submerged arc welded yeeb nkab txoj kev: tom qab ntau stamping ntawm JC0 txoj kev tshuab, thawj ib nrab ntawm cov hlau phaj yog nias rau hauv J puab, thiab tom qab ntawd lwm yam. ib nrab ntawm cov hlau phaj yog nias rau hauv J hom, tsim C zoo, nias los ntawm nruab nrab los ua ib qho qhib "O"-puab raj dawb paug.

Kev sib piv ntawm JCO thiab UO molding txoj kev:

JCO forming yog kev ua haujlwm siab, uas hloov cov txheej txheem ntawm cov yeeb nkab steel los ntawm ob kauj ruam ntawm UO ua rau ntau kauj ruam. Thaum lub sij hawm tsim cov txheej txheem, cov hlau phaj yog uniformly deformed, cov residual kev nyuaj siab yog me me, thiab cov nto tsis khawb. Muaj qhov yooj yim dua ntawm qhov loj thiab qhov tshwj xeeb ntawm cov phab ntsa tuab, uas tuaj yeem tsim cov khoom ntim loj thiab cov khoom me me, tsis yog tsuas yog loj-inch high-strength tuab-walled steel kav, tab sis kuj me-inch loj- walled steel kav, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov zoo tuab-walled kav, tshwj xeeb tshaj yog zus tau tej cov me me thiab nruab nrab-inch tuab-walled kav, nws muaj incomparable zoo dua lwm yam txheej txheem, thiab muaj peev xwm ua tau raws li cov kev cai ntau ntawm cov neeg siv rau steel yeeb nkab specifications. . UO forming adopts U thiab O siab tsim ob zaug, uas yog yus muaj los ntawm nws muaj peev xwm loj thiab siab tso zis ntau lawm. Feem ntau, cov zis txhua xyoo tuaj yeem ncav cuag 300,000 txog 1,000,000 tons, uas yog tsim rau kev tsim khoom loj ntawm ib qho tshwj xeeb.

3. Ncaj seam siab zaus kuj welded yeeb nkab

Ncaj seam high-frequency welded yeeb nkab (ERW) yog tsim los ntawm kev siv cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj ntawm high-frequency tam sim no kom sov thiab yaj lub ntug ntawm lub raj dawb paug tom qab lub kub dov kauj yog tsim los ntawm ib tug sib sau tshuab, thiab ces. siab-welded nyob rau hauv qhov kev txiav txim ntawm extrusion roller.
