Kauv rajyog 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 pub lub steel sawb mus rau hauv lub welded yeeb nkab unit. Tom qab tau dov los ntawm ntau lub chais, cov sawb hlau yog maj mam dov los ua ib lub voj voos kheej kheej nrog 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 qhov kawg ntawm qhov sib koom ua ke.

Spiral yeeb nkab khoom:
Q235A, Q235B, 10#, 20#, Q345 (16Mn),
L245(B), L290(X42), L320(X46), L360(X52), L390(X56), L415(X60), L450(X65), L485(X70), L555(X80)

L290NB/MB(X42N/M), L360NB/MB(X52N/M), L390NB/MB(X56N/M), L415NB/MB(X60N/M), L450MB(X65), L485MB(X70), L555MB(X80) .

Spiral yeeb nkab txheej txheem:

(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) Tag nrho cov welded seams raug tshuaj xyuas los ntawm online nruam ultrasonic tsis siv neeg qhov tsis pom kev, uas ua kom 100% tsis muaj kev puas tsuaj rau kev ntsuas ntawm cov 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. yeeb nkab ua txheej txheem tsim nyog ua ntej 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 hlab uas lub sawb steel pob tw welds thiab D-joints intersected nrog cov kauv welds yog tag nrho cov soj ntsuam los ntawm X-ray TV los yog zaj duab xis.
(13) Txhua cov yeeb nkab steel tau dhau los ntawm kev ntsuas hydrostatic siab, 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.

Cov txheej txheem tseem ceeb ntawm cov kav dej kauv:

ib. 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 kev hloov pauv ntau dua 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.
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 qhov system 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.

Cov txheej txheem stacking ntawm kauv kav yuav tsum:
1. Lub hauv paus ntsiab lus yuav tsum tau ua ntawm kauv steel yeeb nkab stacking yog pawg raws li ntau yam thiab specifications nyob rau hauv lub premise ntawm ruaj khov stacking thiab ua kom muaj kev ruaj ntseg. Cov khoom sib txawv yuav tsum tau muab sib cais sib cais los tiv thaiv kev tsis sib haum xeeb thiab kev sib tsoo;
2. Nws yog txwv tsis pub khaws cov khoom uas corrode steel nyob ib ncig ntawm pawg ntawm kauv steel kav;
3. Cov kab hauv qab ntawm cov kav hlau kav yuav tsum siab, ruaj khov thiab tiaj tus kom tsis txhob muaj cov khoom ntub los yog deformed;
4. Cov khoom siv tib yam yog stacked nyias raws li qhov kev txiav txim ntawm kev cia;
5. Rau cov kav hlau kav uas muab kauv tso rau hauv qhov qhib cua, yuav tsum muaj cov ntaub qhwv ntoo lossis cov pob zeb hauv qab, thiab cov txheej txheej txheej yog me ntsis inclined los pab kom cov dej ntws tawm, thiab kev saib xyuas yuav tsum tau them rau qhov muab cov ntaub ntawv ncaj qha los tiv thaiv kev khoov deformation;
6. Lub stacking qhov siab ntawm kauv steel kav yuav tsum tsis txhob ntau tshaj 1.2m rau phau ntawv ua hauj lwm, 1.5m rau cov neeg kho tshuab ua hauj lwm, thiab cov pawg dav yuav tsum tsis txhob ntau tshaj 2.5m;
7. Yuav tsum muaj ib qho channel ntawm cov pawg. Kev tshuaj xyuas channel feem ntau yog 0.5m, thiab cov channel nkag tau nyob ntawm qhov loj ntawm cov khoom thiab cov tshuab thauj khoom, feem ntau 1.5-2.0m;
8. Lub kaum sab xis steel thiab channel steel yuav tsum tau muab tso rau hauv qhov qhib cua, uas yog, lub qhov ncauj yuav tsum tig mus rau hauv qab, thiab I-beam yuav tsum tau muab tso rau hauv vertically. I-channel nto ntawm cov hlau yuav tsum tsis txhob tig ntsej muag, kom tsis txhob muaj dej thiab xeb;

9. Lub hauv qab ntawm pawg yog tsa. Yog hais tias lub warehouse yog nyob rau hauv lub tshav ntuj pob zeb pem teb, nws yuav tsum tau tsa los ntawm 0.1m; Yog tias nws yog av nkos, nws yuav tsum tau tsa los ntawm 0.2-0.5m. Yog tias nws yog qhov chaw qhib, lub pob zeb yuav tsum tau cushioned nrog qhov siab ntawm 0.3-0.5m, thiab cov xuab zeb thiab av nkos yuav tsum tau cushioned nrog qhov siab ntawm 0.5-0.7m.
