CCS Nkoj Hlau Phaj A

Ua kom ntseeg tau qhov zoo thiab qhov cuam tshuam Toughness ntawm CCS Nkoj Hlau Phaj A hauv Shipbuilding

Hauv qhov nyuaj thiab xav tau ntawm kev tsim nkoj, qhov zoo thiab qhov cuam tshuam ntawm CCS Ship Steel Phaj A yog qhov tseem ceeb. Ua kom ntseeg tau cov khoom no yuav tsum tau ua kom zoo zoo uas suav nrog ntau yam ntawm cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo, thiab siv cov ntaub ntawv raug rau kev txheeb xyuas thiab kev ua kom zoo.

Qhov pib ntawm kev ua kom zoo yog kev xaiv cov khoom siv raw. High-quality steel ingots los yog slabs nrog tswj tshuaj muaj pes tsawg leeg yog qhov tseem ceeb. Cov ntsiab lus ntawm cov ntsiab lus xws li carbon, manganese, silicon, sulfur, thiab phosphorus yuav tsum tsis pub dhau qhov txwv kom ua tiav cov khoom xav tau. Cov ntaub ntawv los ntawm kev tshuaj xyuas tshuaj ntawm cov khoom siv raw muab lub hauv paus rau kev ua kom tau raws li cov kev cai no. Piv txwv li, cov ntsiab lus carbon feem ntau yuav tsum nyob hauv thaj tsam ntawm [X]% mus rau [X]%, thiab cov qib sulfur thiab phosphorus yuav tsum tau khaws cia tsis tshua muaj siab, nyiam dua hauv qab [X]% thiab [X]% feem, kom tsis txhob muaj brittleness thiab tsis zoo weldability.

Cov txheej txheem tsim khoom ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo thiab qhov cuam tshuam ntawm CCS Ship Steel Phaj A. Kev ua haujlwm cua sov thiab dov yuav tsum tau tswj hwm kom ua tiav qhov xav tau microstructure. Cov cua kub yuav tsum raug tswj kom raug nyob ib ncig ntawm [X] degree kom ntseeg tau tias homogenization ntawm cov hlau zoo. Thaum lub sij hawm dov txheej txheem, qhov txo qhov piv thiab dov ceev yuav tsum tau optimized kom tau zoo-grained microstructure, uas txhim kho cov neeg kho tshuab zog. Cov ntaub ntawv sau los ntawm cov txheej txheem saib xyuas, xws li ntsuas kub thiab ntsuas ntsuas, pab tswj cov txheej txheem tsis nyob hauv qhov xav tau.

Tshuaj muaj pes tsawg leeg

Kev kho cua sov yog lwm kauj ruam tseem ceeb. quenching thiab tempering txheej txheem tuaj yeem txhim kho qhov cuam tshuam toughness ntawm steel phaj. Qhov kub thiab txias txias yuav tsum tau ua tib zoo tswj kom ua tiav cov martensitic microstructure, ua raws li tempering ntawm qhov tsim nyog kub, feem ntau nyob ib ncig ntawm [X] degree, kom txo hardness thiab nce toughness. Cov txiaj ntsig ntawm kev ntsuas qhov hnyav, xws li Charpy V-notch qhov tseem ceeb, yuav tsum ua tau raws li lossis tshaj qhov yuav tsum tau muaj tsawg kawg nkaus, uas yuav nyob ib puag ncig [X] J ntawm qhov kub thiab txias.

Kev tswj xyuas zoo thiab kev tshuaj xyuas yog qhov tseem ceeb hauv kev tsim khoom. Cov kev sim uas tsis yog kev puas tsuaj xws li kev kuaj ultrasonic thiab kev tshuaj xyuas cov khoom sib nqus yog ua haujlwm los xyuas qhov tsis xws luag sab hauv thiab saum npoo. Kev kuaj ultrasonic tuaj yeem txheeb xyuas qhov tsis zoo xws li suav nrog, voids, thiab tawg hauv lub phaj. Cov ntaub ntawv xeem, suav nrog cov teeb liab amplitudes thiab lub sijhawm nthuav tawm, raug tshuaj xyuas los txiav txim qhov chaw thiab qhov loj ntawm qhov tsis xws luag. Magnetic particle soj ntsuam zoo nyob rau hauv kev soj ntsuam cov kab nrib pleb. Kev siv thiab kev faib tawm ntawm cov qauv sib nqus particle muab cov ntaub ntawv hais txog qhov muaj thiab qhov hnyav ntawm qhov tsis xws luag.

Kev ntsuam xyuas cov cuab yeej cuab tam yog ua los ntawm cov qauv coj los ntawm cov hlau phaj. Kev ntsuas tensile ntsuas lub zog tawm los, lub zog tensile, thiab elongation. Lub zog tawm ntawm CCS Nkoj Hlau Phaj A feem ntau yuav tsum yog tsawg kawg [X] MPa, thiab lub zog tensile yuav tsum nyob rau hauv thaj tsam ntawm [X] rau [X] MPa, nrog rau qhov elongation tsis tsawg tshaj [X]%. Cov kev ntsuam xyuas cuam tshuam, raws li tau hais ua ntej, muab cov ntaub ntawv tseem ceeb ntawm qhov cuam tshuam rau qhov hnyav. Kev ntsuam xyuas hardness kuj tseem pab ntsuas qhov sib xws ntawm kev kho cua sov.
