Hom thiab cov ntsiab lus ntawm Alloy Elements

 

Molybdenum (hli): Cov khoom molybdenum tuaj yeem txhim kho lub zog thiab lub zog ntawm cov nkoj tsim steel daim hlau, tshwj xeeb tshaj yog kev ua haujlwm nyob rau hauv qhov kub thiab txias thiab nyuaj - kev ntxhov siab. Thaum lub sij hawm tsim cov txheej txheem, molybdenum tuaj yeem cuam tshuam cov pearlite transformation thiab ua kom zoo dua cov qauv nplej. Rau qee lub nkoj tsim steel daim hlau uas yuav tsum tau tiv taus qhov kub thiab txias (xws li cov qauv nyob ze ntawm lub nkoj lub cav) lossis kev ntxhov siab siab (xws li hneev taw ntawm lub icebreaker), qhov sib ntxiv ntawm molybdenum tuaj yeem txhim kho lawv cov kev ua tau zoo. Hauv Qib E shipbuilding steel daim hlau, qhov tsim nyog ntxiv ntawm molybdenum keeb pab txhim kho nws cov kev ua haujlwm tiv thaiv kev tawg thiab tag nrho lub zog hauv qhov chaw txias heev.

 

Vanadium (V), Niobium (Nb), thiab Titanium (Ti): Cov ntsiab lus no yog micro- alloying ntsiab nyob rau hauv shipbuilding steel daim hlau. Lawv tuaj yeem kho cov nplej los ntawm kev tsim cov carbide, nitrides, thiab lwm yam sib xyaw, yog li txhim kho lub zog thiab tawv ntawm cov hlau. Piv txwv li, nyob rau hauv cov txheej txheem tswj dov thiab tswj cua txias (TMCP), cov micro- alloy cov ntsiab lus tuaj yeem tswj cov qoob loo loj hlob zoo thiab ua kom lub nkoj tsim cov hlau phaj kom tau txais cov khoom zoo dua qub. Lawv lub luag haujlwm tseem ceeb tshwj xeeb hauv kev tsim cov khoom siv siab-lub zog shipbuilding steel daim hlau.

 

Cov txheej txheem ntau lawm

 

Rolling txheej txheem: Cov tsis muaj nyob hauv cov txheej txheem dov muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm nkoj tsim cov hlau phaj. Piv txwv li, dov kub, dov ceev, thiab txo tus nqi. Ntawm qhov ua tiav qis dua - dov kub, cov nplej tuaj yeem ua kom zoo dua qub, thiab lub zog thiab tawv ntawm cov hlau tuaj yeem txhim kho. Rau tuab - specification shipbuilding steel daim hlau, kev saws los ntawm kev tswj dov txheej txheem tuaj yeem ua rau cov qauv sab hauv ntawm cov hlau zoo sib xws, yog li txhim kho nws cov kev ua tau zoo. Piv txwv li, nyob rau hauv zus tau tej cov Qib E shipbuilding steel daim hlau, nyob rau hauv thiaj li yuav ua tau raws li nws cov kev ua tau zoo yuav tsum tau nyob rau hauv qhov chaw txias heev.

Qhov cuam tshuam ntawm Impurity Elements

 

Sulfur (S) thiab Phosphorus (P): Sulfur thiab phosphorus yog teeb meem impurity ntsiab nyob rau hauv shipbuilding steel daim hlau. Sulfur yuav tsim sulfide inclusions nyob rau hauv steel, txo cov toughness ntawm hlau. Tshwj xeeb tshaj yog thaum lub sij hawm kub - ua hauj lwm txheej txheem, nws yuav ua rau kub - brittleness. Phosphorus yuav txo qhov toughness ntawm cov hlau, tshwj xeeb tshaj yog nyob rau hauv qis - kub ib puag ncig, ua kom txias - brittleness ntawm hlau. Yog li ntawd, thaum lub sij hawm tsim cov txheej txheem ntawm shipbuilding steel daim hlau, cov ntsiab lus ntawm leej faj thiab phosphorus yuav tsum tau nruj me ntsis tswj los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov hlau. Piv txwv li, high-zoo shipbuilding steel daim hlau yuav tsum tau cov ntsiab lus ntawm leej faj thiab phosphorus kom tsawg li tsawg tau. Feem ntau, cov ntsiab lus sulfur yuav tsum tsawg dua 0.01% - 0.02%, thiab cov ntsiab lus phosphorus yuav tsum tsawg dua 0.015% - 0 .025%.
