Kauv steel yeeb nkab yog qhov zoo thiab tus nqi qis
Kauv steel yeeb nkab yog ib tug kauv seam steel yeeb nkab ua los ntawm sawb steel kauj raws li raw khoom, feem ntau tsim los ntawm sov extrusion thiab welded los ntawm tsis siv neeg muab ob npaug rau hlau ob-sided submerged arc vuam txheej txheem. Lub kauv steel yeeb nkab xa cov hlua hlau mus rau welded yeeb nkab chav tsev. Tom qab dov los ntawm ntau lub chais, cov sawb hlau yog maj mam dov los ua ib lub voj voog cov yeeb nkab tsis muaj qhov qhib qhov sib txawv. Kho qhov txo qis ntawm cov menyuam extrusion los tswj qhov sib txawv ntawm qhov sib txawv ntawm 1 ~ 3mm thiab ua rau ob qho kawg ntawm cov welded junction flush.
(1) Cov khoom siv raw, xws li sawb steel kauj, vuam hlau thiab flux. Kev tshuaj xyuas lub cev thiab tshuaj lom neeg nruj yuav tsum tau ua ua ntej nkag.
(2) Lub pob tw ntawm sawb hlau taub hau thiab tus Tsov tus tw siv ib lub xaim lossis ob lub xaim submerged arc vuam, thiab tsis siv neeg submerged arc vuam yog siv los kho vuam tom qab dov rau hauv cov yeeb nkab steel.
(3) Ua ntej kev tsim, cov hlau sawb yog leveled, trimmed, npaj, deg ntxuav, thauj thiab ua ntej khoov.
(4) Lub tshuab hluav taws xob tiv tauj lub ntsuas hluav taws xob yog siv los tswj lub siab ntawm lub tog raj kheej nias ntawm ob sab ntawm lub conveyor kom ntseeg tau tias kev thauj mus los zoo ntawm cov hlua hlau.
(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 yuav tsum tau ua ntawm vuam, thiab cov yeeb nkab txoj kab uas hla, misalignment thiab weld gap yog nruj me ntsis tswj.
(7) Ob lub vuam sab hauv thiab sab nraud vuam txais yuav American Lincoln Electric vuam tshuab rau ib lub xaim lossis ob lub xaim submerged arc vuam, thiaj li tau txais cov vuam zoo.
(8) Tag nrho cov welded welds raug tshuaj xyuas los ntawm on-line nruam ultrasonic tsis siv neeg qhov tsis pom kev los xyuas kom meej 100% NDT kev pab them nqi ntawm kauv welds. Yog tias muaj qhov tsis xws luag, nws yuav cia li ceeb toom thiab tshuaj tsuag cov cim, thiab cov neeg ua haujlwm tsim khoom yuav kho cov txheej txheem tsis tu ncua txhua lub sijhawm kom tshem tawm qhov tsis xws luag hauv lub sijhawm.
(9) Cov yeeb nkab steel yog txiav rau hauv ib qho los ntawm lub tshuab cua plasma.
(10) Tom qab txiav rau hauv ib lub yeeb nkab steel, txhua batch ntawm cov yeeb nkab steel yuav tsum tau ua raws li kev tshuaj xyuas thawj zaug los xyuas cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, fusion mob, nto zoo ntawm cov yeeb nkab steel thiab NDT kom ntseeg tau tias cov yeeb nkab ua. txheej txheem tsim nyog ua ntej nws tuaj yeem raug muab tso rau hauv ntau lawm.
(11) Cov khoom uas muaj qhov tsis txaus ntseeg nrhiav pom cov cim ntawm lub vuam yuav tsum tau kuaj xyuas los ntawm phau ntawv ultrasonic thiab X-ray. Yog tias muaj qhov tsis xws luag, tom qab kho, lawv yuav tsum raug rau NDT dua kom txog thaum nws tau lees paub tias qhov tsis xws luag raug tshem tawm.
(12) Cov yeeb nkab ntawm lub taub qab vuam seam ntawm sawb hlau thiab T-joint sib tshuam kauv vuam yuav tsum raug tshuaj xyuas los ntawm X-ray TV lossis zaj duab xis.
(13) Txhua cov yeeb nkab steel yog raug kuaj hydrostatic, thiab lub siab txais radial foob. Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm microcomputer nrhiav kom pom cov khoom ntawm steel yeeb nkab dej siab. Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
(14) Cov yeeb nkab kawg yog machined kom raug tswj lub perpendicularity, txoj kab nqes thiab blunt ntug ntawm lub ntsej muag kawg.
1. Yog tias qhov sib txawv loj dhau lawm, qhov sib thooj ntawm qhov sib thooj yuav raug txo, qhov eddy tam sim no kub yuav tsis txaus, thiab qhov sib txuas ntawm qhov sib txuas ntawm qhov sib txuas yuav tsis zoo, ua rau tsis tiav fusion lossis tawg.
2.Yog tias qhov sib txawv me me dhau lawm, qhov sib thooj ntawm qhov sib thooj yuav nce, qhov vuam kub yuav loj dhau, thiab qhov vuam yuav raug hlawv; Los yog lub weld yog extruded thiab dov los tsim ib tug sib sib zog nqus qhov, uas cuam tshuam rau qhov zoo ntawm qhov chaw ntawm weld.
Tom qab ob lub npoo ntawm lub raj khoob yog rhuab mus rau qhov kub thiab txias, cov hlau zoo sib xws yog tsim nyob rau hauv lub extrusion ntawm cov menyuam extrusion, uas nkag mus thiab crystallize nrog txhua lwm yam, thiab thaum kawg tsim ib tug ruaj khov weld. Yog hais tias lub extrusion quab yuam ntawm kauv steel yeeb nkab yog me me dhau lawm, tus naj npawb ntawm cov khoom siv lead ua yuav me me, lub zog ntawm vuam hlau yuav txo qis, thiab tawg yuav tshwm sim tom qab kev ntxhov siab; Yog hais tias lub extrusion quab yuam loj heev, cov hlau molten yuav extruded tawm ntawm lub weld, uas yuav tsis tsuas yog txo lub zog ntawm weld, tab sis kuj tsim ib tug loj tus naj npawb ntawm sab hauv thiab sab nraud burrs, thiab txawm yuav ua rau tsis xws luag xws li vuam sib tshooj.
