LR Nkoj Hlau Phaj EH32

Tswj cov tshuaj muaj pes tsawg leeg ntawm LR Nkoj Hlau Phaj EH32

Cov tshuaj muaj pes tsawg leeg ntawm LR Ship Steel Phaj EH32 plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws cov khoom siv kho tshuab, ua haujlwm ntev, thiab kev ua haujlwm tag nrho. Kev tswj xyuas qhov sib xyaw kom raug yog ib txoj haujlwm tseem ceeb uas yuav tsum muaj kev sib xyaw ua ke ntawm cov txheej txheem tsim khoom thiab cov kev tswj xyuas nruj.

Pib nrog, xaiv cov khoom siv raw yog qhov tseem ceeb tshaj plaws. Cov hlau ore, coke, thiab lwm yam khoom siv ntxiv yuav tsum muaj cov khoom sib xws thiab paub cov tshuaj lom neeg. Piv txwv li, cov hlau ore yuav tsum muaj kev tswj cov ntsiab lus xws li hlau, silicon, manganese, thiab phosphorus. Cov ntaub ntawv los ntawm ntau qhov chaw qhia tau hais tias cov ntsiab lus hlau hauv cov ore yuav tsum feem ntau nyob hauv thaj tsam ntawm [X1]% rau [X2]% kom ntseeg tau qhov zoo ntawm cov hlau kawg.

Thaum lub sij hawm steelmaking txheej txheem, qhov sib ntxiv ntawm alloying ntsiab yog ua tib zoo saib xyuas thiab tswj. Manganese, piv txwv li, yog ntxiv los txhim kho lub zog thiab toughness ntawm cov hlau. Tus nqi ntawm manganese ntxiv yog feem ntau nyob rau hauv thaj tsam ntawm [Y1]% mus rau [Y2]%, thiab cov kev ntsuas thiab tswj tau raug siv los xyuas qhov no. Cov ntaub ntawv los ntawm kev tshawb xyuas lub sijhawm tiag tiag thaum lub sijhawm ua cov txheej txheem steel pab kho cov manganese ntxiv kom ua tiav qhov kev xav tau.
 

Kev pabcuam: Sandblasting thiab primer

Kev tswj cov ntsiab lus carbon yog lwm qhov tseem ceeb. Cov pa roj carbon monoxide muaj qhov cuam tshuam loj rau lub hardness thiab lub zog ntawm cov hlau. Rau LR Nkoj Hlau Phaj EH32, cov ntsiab lus carbon feem ntau yog khaws cia hauv qhov nqaim, hais [Z1]% rau [Z2]%. Advanced analytical techniques, xws li optical emission spectroscopy los yog mass spectrometry, yog siv los ntsuas cov ntsiab lus carbon ntawm ntau theem ntawm cov txheej txheem. Cov txheej txheem no muab cov ntaub ntawv raug nyob rau hauv ib lub vib nas this, tso cai rau kev hloov kho tam sim yog tias qib carbon deviates ntawm lub hom phiaj.

Kev tswj cov sulfur thiab phosphorus yog qhov tseem ceeb sib npaug vim tias lawv tuaj yeem cuam tshuam rau cov weldability thiab ductility ntawm cov hlau. Cov ntsiab lus sulfur feem ntau txwv rau qhov siab tshaj plaws ntawm [A1]%, thiab phosphorus rau [A2]%. Cov txheej txheem tshwj xeeb desulfurization thiab dephosphorization yog siv los txo cov theem ntawm cov impurities. Cov ntaub ntawv los ntawm cov txheej txheem no qhia tau hais tias los ntawm kev siv txoj kev kho kom zoo, cov ntsiab lus ntawm sulfur thiab phosphorus tuaj yeem raug txo los ntawm [B1]% thiab [B2]% feem, ua rau cov hlau zoo dua qub.

Qhov txias txias tom qab cov hlau tau ua tiav kuj cuam tshuam cov tshuaj lom neeg kawg. Kev ua kom txias sai tuaj yeem tiv thaiv kev sib cais ntawm qee cov ntsiab lus thiab txhawb nqa ntau hom microstructure. Kev sim cov ntaub ntawv tau pom tias qhov cua txias ntawm [C] degree ib ob nyob rau hauv ib qho kev ntsuas kub tuaj yeem ua rau muaj kev sib faib ntau dua ntawm cov hlau alloying thiab txhim kho cov khoom siv kho tshuab.
