ABS AH32 Ship Building Siv Marine Qib Steel Phaj

Qhov cuam tshuam ntawm Sulfur rau Vuam Tshuab ntawm ABS AH32 Ship Building Siv Marine Qib Steel Phaj

 

Hauv kev tsim cov nkoj, kev xaiv cov hlau hlau uas tsim nyog yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov nkoj. ABS AH32 nkoj tsim kev tsim kho marine qib steel phaj yog dav siv vim nws cov khoom siv zoo heev. Txawm li cas los xij, muaj leej faj nyob rau hauv cov hlau no tuaj yeem muaj kev cuam tshuam loj rau nws cov cuab yeej vuam. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov cuam tshuam ntawm leej faj ntawm kev sib txuas ntawm ABS AH32 steel phaj kom meej.

 

Taw qhia

 

Shipbuilding yog ib tug complex thiab xav tau kev lag luam uas yuav tsum tau cov ntaub ntawv zoo thiab advanced vuam cov txheej txheem. ABS AH32 steel yog lub zog muaj zog qis-alloy steel tshwj xeeb tsim rau kev siv dej hiav txwv. Nws muaj lub zog zoo, toughness, thiab corrosion kuj, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau lub nkoj hulls thiab lwm yam khoom siv.

 

Vuam yog cov txheej txheem tseem ceeb hauv kev tsim nkoj vim nws koom nrog ntau qhov sib txawv ntawm cov qauv ua ke. Qhov zoo ntawm welds ncaj qha cuam tshuam lub zog thiab durability ntawm lub nkoj. Yog li ntawd, kev nkag siab txog cov xwm txheej uas tuaj yeem cuam tshuam rau vuam yog qhov tseem ceeb rau kev ua tiav ntawm kev tsim cov nkoj nkoj.

 

Sulfur hauv Steel

 

Sulfur yog ib qho impurity uas tuaj yeem muaj nyob hauv cov hlau sib txawv. Nyob rau hauv ABS AH32 steel, sulfur feem ntau txwv rau qee feem pua ​​​​ntawm cov khoom uas xav tau thiab weldability. Txawm li cas los xij, txawm tias me me ntawm cov sulfur tuaj yeem cuam tshuam rau txoj kev vuam.

Mitigating cov teebmeem ntawm Sulfur

 

Tswj cov ntsiab lus sulfur
Ib txoj hauv kev zoo tshaj plaws los txo qhov cuam tshuam ntawm sulfur ntawm vuam yog tswj nws cov ntsiab lus hauv cov hlau. Qhov no tuaj yeem ua tiav los ntawm kev siv cov hlau tsis muaj sulfur tsawg lossis los ntawm kev qhia qhov siab tshaj plaws ntawm cov ntsiab lus sulfur hauv cov khoom specification.

Cov txheej txheem vuam
Cov txheej txheem vuam kom raug kuj tuaj yeem pab txo qis qhov cuam tshuam ntawm sulfur. Qhov no suav nrog kev siv cov khoom siv vuam tsim nyog, preheating cov hlau ua ntej vuam, thiab tswj cov vuam tsis xws li tam sim no, qhov hluav taws xob, thiab kev ceev ceev.

 

Preheating cov hlau tuaj yeem pab txo qhov kev pheej hmoo ntawm kub tawg los ntawm kev txo cov cua txias ntawm vuam. Kev siv cov khoom siv hluav taws xob qis qis kuj tuaj yeem pab txo qis kev tsim cov roj hydrogen sulfide thiab porosity.

 

Kev kho cua sov tom qab Weld
Kev kho cua sov tom qab vuam tuaj yeem siv los txhim kho cov khoom siv kho tshuab thiab txo cov kev ntxhov siab nyob hauv welds. Qhov no tseem tuaj yeem pab txo qhov kev pheej hmoo ntawm kub tawg thiab txhim kho corrosion kuj ntawm welds.

Kev Tswj Xyuas Zoo
Thaum kawg, kev tswj xyuas zoo xws li kev tshuaj xyuas qhov muag, kev kuaj hluav taws xob, thiab kev kuaj ultrasonic tuaj yeem siv los kuaj xyuas thiab kho cov vuam tsis xws luag los ntawm leej faj. Qhov no tuaj yeem pab ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov qauv welded.
