1. Taw qhia rau Marine Offshore High - Lub Zog Boiler Steel Phaj rau Shipbuilding

 

Marine offshore high - lub zog boiler steel daim hlau rau shipbuilding yog ib qho tseem ceeb ntawm cov khoom siv nyob rau hauv maritime thiab zog sectors. Cov hlau phaj no yog tsim los tiv thaiv cov xwm txheej hnyav ntawm cov dej hiav txwv ib puag ncig thiab kev kub ntxhov thiab kub siab ntawm nkoj boilers.

 

2. Cov yam ntxwv ntawm cov hlau phaj

 

Siab zog: Lawv muaj lub zog tensile zoo, uas tso cai rau lawv tuaj yeem nqa cov khoom hnyav thiab cov qauv kev ntxhov siab. Cov cuab yeej muaj zog yog qhov tseem ceeb rau kev tsim cov nkoj loj thiab cov qauv hauv ntug dej hiav txwv. Piv txwv li, lub zog tawm los ntawm cov hlau phaj no tuaj yeem nyob ntawm 355MPa txog 690MPa lossis siab dua, nyob ntawm seb cov qib tshwj xeeb thiab cov ntawv thov. Lub zog siab no ua rau kev tsim kho ntawm cov nkoj loj dua thiab ruaj khov thiab cov khoom siv loj.

 

Zoo Ductility: Txawm tias lawv lub zog siab, cov phaj hlau no kuj muaj qhov zoo ductility. Ductility yog lub peev xwm ntawm cov khoom siv los deform plastically ua ntej fracturing. Nws ua kom ntseeg tau tias cov hlau tuaj yeem tiv taus qhov cuam tshuam thiab khoov lub zog yam tsis muaj kev ua tsis tiav. Hauv kev tsim cov nkoj, cov cuab yeej no tseem ceeb heev vim tias cov nkoj tau raug nthwv dej, kev sib tsoo, thiab lwm yam khoom hnyav. Lub elongation ntawm kev tawg ntawm cov hlau daim hlau no feem ntau yog tswj hwm ntawm ib theem los lav lawv cov kev ua tau zoo.

 

Weldability: Zoo weldability yog ib qho yuav tsum tau - muaj tus yam ntxwv. Hauv kev tsim cov nkoj, ntau yam khoom sib xyaw ua ke los ntawm kev vuam. Cov hlau phaj yuav tsum muaj cov khoom uas tso cai rau kev sib xyaw kom zoo thiab kev sib txuas lus thaum lub sij hawm vuam txheej txheem. Qhov no suav nrog kev muaj cov tshuaj lom neeg tsim nyog uas txo qhov tsim ntawm vuam tsis xws li tawg, porosity, thiab slag inclusions.

3. Kev siv hauv nkoj tsim

 

Nkoj Hulls: Cov hlau phaj yog siv los tsim cov khoom loj ntawm cov nkoj. Lub siab - lub zog thiab corrosion - cov khoom ua haujlwm ua kom muaj kev ncaj ncees thiab ua haujlwm ntev ntawm lub nkoj, tiv thaiv lub nkoj los ntawm cov dej hiav txwv corrosive thiab tiv thaiv hydrostatic thiab hydrodynamic pressures. Lawv kuj ua lub luag haujlwm hauv kev tswj hwm kev ruaj ntseg ntawm lub nkoj thaum caij nkoj thiab hauv hiav txwv sib txawv.

Boiler Cheebtsam: Nyob rau hauv lub nkoj lub boiler system, cov high-lub zog steel daim hlau yog siv los fabricate Cheebtsam xws li cov hlab ntsha siab, chav nruas, thiab tshav kub exchangers. Kev muaj peev xwm tiv taus qhov kub thiab txias siab yog qhov tseem ceeb ntawm no. Cov hlau phaj tiv thaiv qhov kev pheej hmoo ntawm kev tawg ntawm boiler vim yog over-pressurization los yog cov khoom tsis ua hauj lwm nyob rau hauv huab cua kub.

Superstructures: Lub superstructures ntawm cov nkoj, nrog rau cov decks, cabins, thiab masts, kuj yog tsim los ntawm cov hlau phaj. Lawv lub siab - lub zog thiab zoo - saib saum npoo tiav (tom qab kev kho mob tsim nyog) muab cov qauv txhim khu kev qha thiab zoo nkauj rau cov neeg coob thiab cov khoom siv ntawm lub nkoj.
