NK Qib A Shipbuilding Steel Phaj muaj kev ua haujlwm zoo vuam. Cov lus qhia tshwj xeeb yog raws li hauv qab no:

Chemical Composition Conducive rau Vuam

 

Los ntawm qhov kev xav ntawm nws cov tshuaj muaj pes tsawg leeg, cov ntsiab lus carbon (C) hauv NK Qib A steel phaj yog nce mus txog {{0}}}.21% feem ntau. Cov ntsiab lus tsis tshua muaj cov pa roj carbon monoxide pab txo qhov muaj peev xwm ntawm kev tsim cov txheej txheem nyuaj thiab nkig thaum lub sij hawm vuam thiab txo qhov kev pheej hmoo ntawm vuam tawg. Cov ntsiab lus silicon (Si) yog nce mus txog 0.50% feem ntau, cov ntsiab lus manganese (Mn) yog 2.5 npaug ntawm cov pa roj carbon, thiab phosphorus (P) thiab sulfur (S) cov ntsiab lus yog ob qho tib si txog 0.035. % feem ntau. Qhov kev faib ua feem ntawm cov ntsiab lus no ua rau cov hlau tswj tau zoo toughness thiab lub zog nyob rau hauv lub tshav kub cuam tshuam cheeb tsam ntawm vuam, uas yog ib qho txiaj ntsig zoo rau kev ua tiav ntawm cov txheej txheem vuam thiab lav qhov zoo ntawm cov pob qij txha.

Muaj feem xyuam rau ntau txoj kev vuam

 

Shielded Hlau Arc Vuam: Qhov no yog ib qho ntawm feem ntau siv vuam txoj kev hauv nkoj tsim. Rau NK Qib A steel daim hlau, qhov tsim nyog vuam electrodes tuaj yeem xaiv tau, xws li qis-hydrogen electrodes uas ua tau raws li cov qauv ntawm cov koom haum kev faib tawm, uas tuaj yeem phim cov hlau phaj hlau zoo thiab ua tiav kev sib txuas ruaj khov. Thaum lub sij hawm vuam txheej txheem, lub arc yog ruaj khov, thiab cov duab ntawm lub pas dej ua ke molten thiab tsim cov welding tuaj yeem tswj tau zoo, thiaj li yuav tau txais ib qho vuam nrog zoo zoo thiab txhim khu kev qha zoo.

Submerged Arc Vuam: Nws yog siv dav hauv cov xwm txheej xws li thaj tsam loj ntawm NK Qib A steel daim hlau. Nws muaj cov yam ntxwv ntawm kev siv vuam zoo thiab zoo weld zoo. Los ntawm kev xaiv ib qho tsim nyog ua ke ntawm vuam hlau thiab flux, piv txwv li, siv cov vuam hlau nrog cov muaj pes tsawg leeg zoo ib yam li cov hlau hauv paus ua ke nrog cov flux tshwj xeeb, nws tuaj yeem ua kom zoo fusion ntawm cov hlau vuam thiab cov hlau hauv paus, thiab cov cuab yeej cuab tam ntawm lub vuam tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov qauv nkoj. Ntxiv mus, cov txheej txheem submerged arc vuam muaj qhov tob tob tob, uas tuaj yeem ua kom muaj zog ntawm qhov sib koom ua ke.

 

Kev ntseeg tau zoo ntawm Welded Joints

 

Lub zog sib piv: Tom qab welding tiav, lub zog ntawm cov welded sib koom ua ke tuaj yeem phim cov hlau puag zoo. Nws lub zog tawm los, lub zog tensile thiab lwm yam ntsuas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub nkoj kom dais ntau yam kev thauj khoom thaum lub sijhawm ua haujlwm tiag tiag, kom ntseeg tau tias lub zog tag nrho ntawm lub nkoj qauv. Piv txwv li, thaum ua qhov kev ntsuam xyuas tensile, lub zog tensile ntawm qhov sib koom ua ke tuaj yeem ncav cuag ib theem zoo ib yam li cov hlau hauv paus, thiab yuav tsis muaj kev sib txuas tsis muaj zog los ntawm vuam.

Zoo Toughness: Cov welded pob qij txha ntawm NK Qib A steel daim hlau kuj tseem tuaj yeem tswj tau zoo toughness nyob rau hauv qis kub ua hauj lwm tej yam kev mob thiab lwm yam kev mob. Qhov no yog ib qho tseem ceeb heev thaum lub nkoj tab tom taug kev hauv hiav txwv txias lossis ntsib kev cuam tshuam tsis txaus ntseeg. Los ntawm kev ntsuam xyuas kev cuam tshuam, nws tuaj yeem pom tias cov pob qij txha welded tseem muaj qhov cuam tshuam txaus rau hauv qhov chaw qis qis, uas tuaj yeem tiv thaiv qhov pib thiab nthuav tawm ntawm cov kab nrib pleb thiab tiv thaiv kev tawg ntawm qhov chaw welded, yog li ua kom muaj kev nyab xeeb ntawm cov khoom siv. nkoj qauv.

Yooj yim kom tau raws li cov txheej txheem vuam yuav tsum tau

 

Hauv kev ua haujlwm vuam tiag tiag, NK Qib A steel daim hlau muaj cov qauv zoo ib yam rau kev npaj ua haujlwm ua ntej vuam, xws li zawj ua thiab ntxuav cov welded qhov chaw, thiab tsis tas yuav tsum muaj kev kho tshwj xeeb nyuaj heev. Cov txheej txheem tsis sib xws thaum vuam, xws li vuam tam sim no, qhov hluav taws xob, thiab vuam ceev, kuj tseem yooj yim los txiav txim thiab tswj. Ntev npaum li cov txheej txheem vuam tau ua raws, kev sib koom ua ke nrog cov khoom tsim nyog tuaj yeem tau txais, uas tseem ua rau cov welders ua tiav cov haujlwm vuam ntawm NK Qib A steel daim hlau ua haujlwm zoo dua thaum lub sijhawm tsim khoom thiab kho nkoj.
