Thaum lub sij hawm tsim cov submerged arc steel kav, qhov kub thiab txias yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias qhov kev ntseeg tau ntawm vuam. Yog tias qhov ntsuas kub qis dhau lawm, txoj haujlwm vuam yuav tsis ncav cuag qhov ntsuas kub uas yuav tsum tau ua rau vuam. Thaum feem ntau ntawm cov qauv hlau tseem muaj zog, nws yog qhov nyuaj rau cov hlau ntawm ob qho kawg kom nkag mus rau ib leeg thiab koom ua ke. Lub sijhawm ntawd, thaum qhov kub thiab txias heev, muaj ntau cov hlau nyob hauv lub xeev molten ntawm qhov chaw vuam. Qhov kev ntxhib los mos ntawm cov khoom no yog mos heev thiab muaj qhov sib txuam fluidity, thiab tej zaum yuav muaj cov molten droplets. Thaum xws li hlau dripped, Kuj tseem tsis muaj hlau txaus nkag mus rau ib leeg. Thiab thaum lub sij hawm welding, yuav muaj ib co unevenness thiab welding seams los tsim molten qhov.

Submerged arc steel kav yuav siv tau rau kev thauj mus los ua kua: dej thiab dej. Rau kev thauj mus los roj: thee roj, nkev, roj av liquefied. Rau lub hom phiaj: piling kav, txuas hniav; Cov kav dej rau cov docks, txoj kev, cov qauv hauv tsev, thiab lwm yam Submerged arc steel kav yog muab kauv seam steel kav uas yog ua los ntawm cov sawb steel coils raws li raw cov ntaub ntawv, extruded ntawm qhov kub thiab txias, thiab welded los ntawm tsis siv neeg ob-xaim ob-sided submerged arc vuam tshuab. . Lub taub hau thiab tus Tsov tus tw ntawm steel sawb yog pob tw-sib koom siv ib leeg-xaim los yog ob-xaim submerged arc vuam. Tom qab dov mus rau hauv cov yeeb nkab steel, tsis siv neeg submerged arc vuam yog siv los kho vuam. Siv kev tswj sab nraud lossis sab hauv kev tswj cov menyuam ua. Ob qho tib si sab hauv thiab sab nraud siv hluav taws xob vuam tshuab rau ib leeg-xaim lossis ob-xaim submerged arc vuam kom tau txais cov khoom siv vuam ruaj khov.

Kev tshuaj xyuas dab tsi ua rau cov kav dej arc steel yuav tsum tau ua tom qab tsim khoom?
(1) Hydraulic siab xeem: Cov kav hlau txuas tau raug tshuaj xyuas ib qho los ntawm ib qho ntawm lub tshuab ntsuas hydraulic kom ntseeg tau tias cov kav hlau ua tau raws li qhov kev sim siab xav tau los ntawm tus qauv. Lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia;
(2) Txoj kab uas hla: Tag nrho qhov ntev ntawm lub submerged arc steel yeeb nkab tau nthuav dav los txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho kev faib tawm ntawm kev ntxhov siab hauv cov yeeb nkab steel;
(3) X-ray tshuaj ntsuam II: X-ray muaj TV tshuaj xyuas thiab cov yeeb nkab kawg weld photography yog ua nyob rau hauv cov yeeb nkab steel tom qab txoj kab uas hla expansion thiab hydraulic siab test;
(4) Magnetic particle soj ntsuam ntawm cov yeeb nkab kawg: Qhov kev tshuaj xyuas no yog ua los xyuas cov yeeb nkab kawg;
(5) X-ray tshuaj xyuas I: X-ray muaj TV tshuaj xyuas ntawm cov welds sab hauv thiab sab nraud, siv cov duab ua haujlwm los xyuas kom meej qhov rhiab heev ntawm qhov tsis zoo;
(6) Tshawb xyuas cov welds sab hauv thiab sab nraud ntawm cov kav hlau kav thiab cov ntaub ntawv hauv paus ntawm ob sab ntawm cov welds;
(7) Sonic soj ntsuam II: Ua sonic tshuaj xyuas dua ib los ntawm ib qho los xyuas qhov tsis xws luag uas yuav tshwm sim tom qab txoj kab uas hla expansion thiab hydraulic siab ntawm cov ncaj seam welded steel kav;
(8) Chamfering: txheej txheem cov yeeb nkab kawg ntawm cov yeeb nkab steel uas tau dhau qhov kev tshuaj xyuas kom ua tiav cov yeeb nkab kawg bevel loj;
(9) Anti-corrosion thiab txheej: Tsim nyog cov kav dej steel yuav tiv thaiv corrosion thiab coated raws li cov neeg siv khoom xav tau.

Lub submerged arc steel yeeb nkab fittings thiab cov rooj sib txoos prefabricated nyob rau hauv cov kev cog qoob loo yuav tsum tau ua kom tiav, uas yog, tag nrho cov vuam pob qij txha tau welded, lub flange pob qij txha tau ntsia nrog lub sij hawm ntev rov qab phaj, thiab tag nrho cov flange bolts tau hnav thiab nruj. . Qhov sib piv tsim tus nqi ntawm sab nraud qhov sib txawv ntawm cov submerged arc steel yeeb nkab sib dhos tsis tuaj yeem tshaj li cov cai hauv qab no; Thaum lub sab nraud ntawm lub submerged arc steel yeeb nkab sib dhos yog 3m, qhov sib txawv yog ± 5mm. Thaum lub sab nraud ntawm lub submerged arc steel yeeb nkab sib dhos nce los ntawm 1m, tus nqi sib txawv tuaj yeem nce los ntawm ± 2 hli, tab sis tag nrho qhov sib txawv tsis tuaj yeem siab dua ± 15mm.

Tes-welded sib dhos nrog flanged kev sib txuas los yog li qub yuav tsum raug kuaj. Txhua lub rooj sib txoos yuav tsum tau sau npe raws li cov yeeb nkab luv luv ntawm cov duab kos, thiab lawv cov qhov hluav taws xob kawg yuav tsum raug kaw nrog cov ntawv dig muag lossis cov ntsaws. Lub qhov hluav taws xob flange ntawm cov yeeb nkab kawg ntawm lub rooj sib txoos tuaj yeem welded khov kho yog tias cov flange bolt qhov sib npaug sib npaug. Yog tias nws yog flange txuas nrog cov khoom siv lossis flange txuas nrog cov ceg flange ntawm lwm cov khoom, nws tsuas yog qhov chaw welded thiab muab tso rau ntawm qhov kawg ntawm cov yeeb nkab. Nws tsuas yog yuav tsum tau positioned tom qab raug thauj mus rau qhov chaw installation thiab ces welded khov kho. Valves tseem yuav tsum tau muab tso rau ntawm lub rooj sib txoos, thiab cov kav dej luv luv rau cov kav dej phwj tuaj thiab cov kav dej, ntsuas ntsuas, thiab cov cim nce rau kev txhim kho zawv zawg brackets yuav tsum tau welded. Sab hauv ntawm cov yeeb nkab prefabricated yuav tsum tau ntxuav. Lub submerged arc steel yeeb nkab sib dhos yuav tsum xav txog qhov yooj yim ntawm kev thauj mus los thiab kev teeb tsa thiab muaj qhov qhib tau nyob. Nws kuj tseem yuav tsum muaj rigidity txaus los tiv thaiv kev deformation mus ntev.
