Galvanized steel kav yog cov khoom siv feem ntau hauv lub neej niaj hnub no, thiab vuam yog txoj kev sib txuas feem ntau siv. Qhov zoo ntawm vuam yog ncaj qha ntsig txog kev nyab xeeb thiab ruaj khov ntawm cov khoom. Yog li cov teeb meem dab tsi peb yuav tsum tau them sai sai rau kom ntseeg tau tias qhov zoo ntawm cov khoom siv welded?

1. Steel yeeb nkab thickness Nyob rau hauv kev tsim thiab siv welded steel kav, lub thickness ntawm cov yeeb nkab steel yog ib qho tseem ceeb heev parameter. Txawm li cas los xij, vim yog vim li cas thiab kev tsim khoom, lub thickness ntawm cov yeeb nkab steel tej zaum yuav muaj qee qhov sib txawv. Cov qauv no qhia cov kev txwv xws li qhov loj, tuab, qhov hnyav, thiab kev kam rau siab ntawm welded steel kav los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov kav hlau. Qhov sib txawv ntawm lub thickness ntawm welded steel kav yuav cuam tshuam qhov zoo thiab kev nyab xeeb ntawm cov kav hlau steel. Yog hais tias lub thickness sib txawv ntawm cov yeeb nkab steel loj heev, nws yuav ua rau cov kabmob muaj peev xwm ntawm cov yeeb nkab steel txo, yog li cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm cov khoom. Txhawm rau tswj qhov sib txawv ntawm qhov tuab ntawm welded steel kav, cov txheej txheem thoob ntiaj teb feem ntau teev cov qauv rau kev tso cai sib txawv ntawm cov thickness ntawm welded steel kav. Hauv kev tsim khoom thiab siv tiag tiag, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj thiab tswj raws li cov qauv kom ntseeg tau qhov zoo thiab kev nyab xeeb ntawm cov kav hlau steel.

Peb nruj me ntsis tswj cov thickness ntawm steel kav. Rau cov yeeb nkab steel ntawm tib qhov tshwj xeeb, lub thickness kam rau ua yog ± 5%. Peb nruj me ntsis tswj qhov zoo ntawm txhua cov yeeb nkab steel. Peb ua cov kev ntsuam xyuas tuab ntawm txhua pawg ntawm cov kav hlau los tiv thaiv cov khoom tsis tsim nyog los ntawm kev nkag mus rau hauv kev ua lag luam, tiv thaiv cov cai thiab kev nyiam ntawm cov neeg siv khoom, thiab xyuas kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm txhua cov yeeb nkab steel.

2. Thaum lub sij hawm vuam txheej txheem ntawm cov kav hlau, lwm qhov tseem ceeb yog kev kho cov yeeb nkab qhov ncauj ntawm cov yeeb nkab steel. Txawm hais tias nws tsim nyog rau vuam zoo heev cuam tshuam qhov zoo ntawm cov khoom tiav tom qab vuam. Ua ntej tshaj plaws, nws yog ib qho tsim nyog yuav tsum ua kom lub qhov ncauj tsis txhob ntab xeb, av, thiab roj. Cov khib nyiab no cuam tshuam rau cov vuam zoo, uas yuav ua rau cov vuam tsis sib xws thiab tawg thaum vuam, thiab tseem cuam tshuam rau tag nrho cov khoom siv vuam. Qhov flatness ntawm qhov hla ntu kuj yog ib qho tseem ceeb uas yuav tsum tau ua ua ntej vuam. Yog hais tias tus ntoo khaub lig qaij dhau lawm, nws yuav ua rau cov yeeb nkab steel khoov thiab tshwm ntawm lub kaum sab xis, cuam tshuam rau kev siv. Thaum vuam, cov burrs, thiab cov khoom txuas ntawm qhov tawg ntawm cov yeeb nkab steel yuav tsum tau kuaj xyuas, txwv tsis pub nws yuav tsis raug welded. Cov burrs ntawm cov yeeb nkab steel tseem yuav khawb cov neeg ua haujlwm thiab ua rau lawv cov khaub ncaws puas thaum lawv ua, uas cuam tshuam rau kev nyab xeeb.

Xav txog cov teeb meem vuam ntawm cov neeg siv, peb tau ntxiv cov txheej txheem ntawm cov yeeb nkab qhov ncauj hauv cov txheej txheem los xyuas kom meej tias cov yeeb nkab qhov ncauj interface yog du, tiaj tus, thiab tsis muaj burr. Thaum siv cov yeeb nkab steel vuam, tsis tas yuav rov txiav cov yeeb nkab lub qhov ncauj, uas yog qhov yooj yim rau cov neeg siv vuam hauv kev siv txhua hnub. Kev siv cov txheej txheem no tuaj yeem tsis tsuas yog txo cov khib nyiab ntawm cov khoom seem uas peb yuav tsum pom hauv vuam ua ntej, tab sis kuj ua kom cov khoom siv tau zoo, txo cov vuam deformation, thiab ntxiv txhim kho vuam zoo ntawm cov khoom.

3. Weld Lub vuam ntawm cov yeeb nkab steel yog hais txog cov vuam tsim los ntawm cov yeeb nkab steel thaum lub vuam txheej txheem. Qhov zoo ntawm cov yeeb nkab steel vuam ncaj qha cuam tshuam rau kev ua haujlwm thiab kev nyab xeeb ntawm cov yeeb nkab steel. Yog tias muaj qhov tsis xws luag hauv cov yeeb nkab steel vuam, xws li pores, slag inclusions, tawg, thiab lwm yam, nws yuav cuam tshuam rau lub zog thiab sealing ntawm cov yeeb nkab steel, uas ua rau cov xau thiab tawg ntawm cov yeeb nkab steel thaum lub sij hawm vuam, yog li cuam tshuam. qhov zoo thiab kev nyab xeeb ntawm cov khoom.

Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov welds, peb tau ntxiv cov khoom siv turbine weld nrhiav kom tau cov kab ntau lawm txhawm rau txheeb xyuas cov txheej txheem vuam ntawm txhua cov yeeb nkab steel. Yog tias muaj teeb meem weld thaum lub sijhawm tsim khoom, lub tswb yuav raug suab tam sim los tiv thaiv cov khoom teeb meem los ntawm kev muab tso rau hauv cov khoom tiav. Peb ua cov kev ntsuam xyuas tsis muaj kev puas tsuaj, kev tshuaj ntsuam metallographic, kev ntsuas cov cuab yeej cuab tam, thiab lwm yam ntawm txhua batch ntawm cov kav hlau steel tawm hauv lub Hoobkas kom ntseeg tau tias cov neeg siv khoom qis qis tsis muaj teeb meem xws li cov khoom tsis ruaj khov thiab kev ua haujlwm qeeb vim muaj teeb meem steel yeeb nkab thaum ua. kev ua haujlwm.
