Kauv steel yeeb nkab yog ib tug kauv seam steel yeeb nkab ua los ntawm sawb steel kauj raws li raw khoom, extruded ntawm qhov kub thiab txias, thiab welded los ntawm tsis siv neeg ob-xaim ob-sided submerged arc vuam txheej txheem.Lub kauv steel yeeb nkab xa cov sawb hlau mus rau hauv cov yeeb nkab welded chav tsev, thiab tom qab dov los ntawm ntau cov chais, cov hlua hlau yog maj mam dov los ua ib lub voj voos raj nrog qhib qhov sib txawv.Kho qhov txo qis ntawm cov menyuam extrusion los tswj cov vuam seam qhov sib txawv ntawm 1 ~ 3mm, thiab ua rau ob qho kawg ntawm qhov chaw nres nkoj vuam.
Txheej txheem ntau lawm
(1) Cov ntaub ntawv raw yog sawb steel coils, vuam hlau, thiab fluxes.Ua ntej muab tso rau hauv kev siv, lawv yuav tsum dhau los ntawm kev ntsuas lub cev thiab tshuaj lom neeg nruj.
(2) Lub taub hau-rau-tail pob tw ntawm sawb steel txais ib leeg-xaim lossis ob-xaim submerged arc vuam, thiab tsis siv neeg submerged arc vuam siv los kho vuam tom qab tau dov rau hauv cov kav hlau.
(3) Ua ntej kev tsim, cov hlau sawb yog leveled, trimmed, npaj, deg ntxuav, thauj thiab pre-bent.
(4) Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej ntawm ob sab ntawm cov khoom siv los xyuas kom meej qhov kev sib tw ntawm cov sawb.
(5) Txais kev tswj sab nraud lossis kev tswj sab hauv yob txoj kev.
(6) Weld gap control device yog siv los xyuas kom meej tias qhov sib txawv weld ua tau raws li qhov xav tau ntawm vuam, thiab cov yeeb nkab txoj kab uas hla, misalignment thiab weld qhov sib txawv yog nruj me ntsis tswj.
(7) Ob leeg hauv vuam thiab sab nraud vuam siv American Lincoln vuam tshuab rau ib leeg-xaim los yog ob-xaim submerged arc vuam, thiaj li kom tau cov vuam zoo.
(8) Cov welded seams yog tag nrho cov tshuaj ntsuam xyuas los ntawm ib qho online nruam ultrasonic tsis siv neeg qhov tsis pom kev, uas ua kom 100% tsis muaj kev puas tsuaj rau kev ntsuas ntawm kauv welds.Yog tias muaj qhov tsis xws luag, nws yuav cia li ceeb toom thiab tshuaj tsuag lub cim, thiab cov neeg ua haujlwm tsim khoom tuaj yeem kho cov txheej txheem tsis raug txhua lub sijhawm raws li qhov no txhawm rau tshem tawm qhov tsis xws luag hauv lub sijhawm.
(9) Siv lub tshuab cua plasma txiav cov yeeb nkab steel rau hauv ib daim.
(10) Tom qab txiav rau hauv ib lub kav hlau, txhua pawg ntawm cov kav hlau yuav tsum tau ua ntej kev soj ntsuam nruj heev los xyuas cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, fusion txheej txheem ntawm cov welds, steel yeeb nkab nto zoo thiab tsis muaj kev puas tsuaj los xyuas kom meej tias cov khoom siv hluav taws xob tsis zoo. Cov txheej txheem ua yeeb nkab yog tsim nyog Tom qab ntawd, nws tuaj yeem raug muab tso rau hauv ntau lawm.
(11) Cov khoom cim los ntawm kev tshawb nrhiav tsis tu ncua ultrasonic flaw ntawm lub vuam yuav tsum tau txais phau ntawv ultrasonic thiab X-ray rov kuaj xyuas.Yog tias muaj qhov tsis xws luag tiag tiag, tom qab kho, lawv yuav tsum tau kuaj xyuas tsis muaj kev puas tsuaj ntxiv mus txog thaum pom tseeb tias cov khoom puas raug tshem tawm.
(12) Cov kav dej uas cov hlua steel pob tw welds thiab D-joints sib tshuam nrog cov kauv welds nyob txhua qhov tau raug tshuaj xyuas los ntawm X-ray TV lossis zaj duab xis.
(13) Txhua cov yeeb nkab steel tau dhau qhov kev sim siab hydrostatic, thiab lub siab yog radially kaw.Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm cov yeeb nkab steel dej siab microcomputer nrhiav kom tau cov cuab yeej.Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
(14) Cov yeeb nkab kawg yog machined kom raug tswj qhov ntsug ntawm lub ntsej muag kawg, lub kaum sab xis thiab lub ntsej muag blunt.
Weld kev kho mob
1. Yog tias qhov sib txawv loj heev, qhov sib thooj ntawm cov nyhuv yuav raug txo, qhov kub ntawm cov eddy tam sim no yuav tsis txaus, thiab intergranular bonding ntawm cov weld yuav tsis zoo, ua rau tsis muaj fusion los yog tawg.
2. Yog tias qhov sib txawv me dhau, qhov sib thooj ntawm qhov sib thooj yuav nce, qhov vuam kub yuav loj dhau, thiab cov vuam vuam yuav raug hlawv;los yog weld seam yuav tsim cov pits sib sib zog nqus tom qab extrusion thiab dov, uas yuav cuam tshuam rau qhov zoo ntawm lub vuam seam.
Tom qab ob lub npoo ntawm lub raj khoob yog rhuab mus rau qhov kub thiab txias, nyob rau hauv lub extrusion ntawm cov menyuam extrusion, cov hlau nplej ntau yog tsim kom nkag mus thiab crystallize ib leeg, thiab thaum kawg tsim ib qho kev ruaj khov.Yog hais tias lub extrusion quab yuam ntawm cov kauv steel yeeb nkab yog me me dhau lawm, tus naj npawb ntawm cov khoom siv lead ua yuav me me, lub zog ntawm cov hlau vuam yuav txo qis, thiab cov kab nrib pleb yuav tshwm sim tom qab kev ntxhov siab;Yog hais tias lub extrusion quab yuam loj heev, cov hlau molten yuav raug nyem tawm ntawm lub vuam, nws tsis tsuas yog txo lub zog ntawm weld seam, tab sis kuj tsim ib tug loj tus naj npawb ntawm sab hauv thiab sab nraud burrs, thiab txawm ua rau tsis xws luag xws li weld laps. .
Cov yam ntxwv txheej txheem
Cov yam ntxwv tseem ceeb ntawm kauv steel yeeb nkab:
a.Thaum lub sij hawm tsim cov txheej txheem, lub deformation ntawm steel phaj yog ib yam, cov residual kev nyuaj siab yog me me, thiab nto tsis tsim khawb.Cov txheej txheem kauv steel yeeb nkab muaj qhov yooj yim dua nyob rau hauv qhov loj thiab qhov tshwj xeeb ntawm txoj kab uas hla thiab phab ntsa tuab, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov kav dej tuab tuab, tshwj xeeb tshaj yog cov kav me me thiab nruab nrab tuab tuab-walled kav.Muaj ntau qhov yuav tsum tau ua nyob rau hauv cov nqe lus ntawm kauv steel yeeb nkab specifications.
b.Siv cov txheej txheem ob-sided submerged arc vuam tshuab, vuam tuaj yeem ua tiav ntawm txoj haujlwm zoo tshaj plaws, thiab nws tsis yooj yim kom muaj qhov tsis xws luag xws li misalignment, vuam sib txawv thiab tsis tiav kev nkag mus, thiab nws yooj yim los tswj cov vuam zoo.
c.Ua tiav 100% kev soj ntsuam zoo ntawm cov kav hlau steel, kom tag nrho cov txheej txheem ntawm cov yeeb nkab steel yog nyob rau hauv kev tshuaj xyuas thiab kev saib xyuas zoo, ua kom cov khoom zoo.
d.Tag nrho cov khoom siv ntawm tag nrho cov kab ntau lawm muaj kev ua haujlwm ntawm kev sib txuas nrog lub khoos phis tawj cov ntaub ntawv tau txais cov ntaub ntawv kom paub txog cov ntaub ntawv xa mus rau lub sijhawm tiag tiag, thiab cov kev tsis sib xws hauv cov txheej txheem tsim khoom raug kuaj xyuas los ntawm lub hauv paus tswj chav.
