Kev tsim cov khoom siv hlau yog cov txheej txheem nyuaj thiab muag heev, uas pib los ntawm kev rho tawm thiab smelting ntawm raw cov ntaub ntawv, thiab tom qab ntawd mus dhau ntau theem ntawm kev ua, thaum kawg nthuav tawm nws tus kheej li ntau yam khoom siv hlau feem ntau pom hauv peb lub neej niaj hnub. Txhua theem muaj cov thev naus laus zis tshwj xeeb thiab cov khoom siv tes ua haujlwm, suav nrog kev tshawb fawb thiab kos duab.
Smelting: tus yuam sij rau hlau purification
Kev tsim cov khoom siv hlau pib nrog kev ua kom zoo thiab smelting ntawm cov ore. Tom qab cov ore tau mined, nws yuav tsum tau smelted kom tshem tawm impurities thiab rho tawm cov hlau ntshiab. Cov txheej txheem smelting feem ntau siv rau hauv cov txheej txheem no suav nrog blast furnace smelting thiab electrolysis. Nyob rau hauv cov ntaub ntawv ntawm steel, piv txwv li, hlau ore yuav tsum tau reacted nrog coke ntawm high kub los tsim npua hlau, uas yog ntxiv purified rau hauv hlau. Cov theem no tsom mus rau kev tswj qhov kub thiab txias thiab kev tswj xyuas cov tshuaj lom neeg kom paub meej tias cov purity thiab zoo ntawm cov hlau.
Casting thiab Forging: Pib tsim cov duab
Tom qab smelting, hlau feem ntau nkag mus rau hauv lub casting los yog forging theem, qhov twg nws yog pib tsim rau hauv nws cov duab. Casting cuam tshuam nrog cov hlau molten rau hauv pwm ntawm ib qho tshwj xeeb uas yuav tsum tau txias thiab tsim, whereas forging hloov cov duab thiab qauv ntawm cov hlau los ntawm cua sov nws thiab ces hammering nws. Cov txheej txheem ob leeg muaj lawv qhov zoo, nrog rau kev tsim cov geometry nyuaj thiab forging txhim kho qhov toughness thiab lub zog ntawm cov hlau.
Kev ua haujlwm txias: zoo shaping thiab tswj qhov ntev
Tom qab casting los yog forging, cov hlau tau dhau los ua cov txheej txheem ua haujlwm txias, xws li dov, ncab thiab stamping, kom ua tiav qhov ntev thiab cov duab. Rolling hloov cov tuab ntawm cov hlau los ntawm kev sib txhuam nws, ncab yog siv los tsim cov khoom siv hlau ntev, nyias nyias, thiab stamping feem ntau yog siv los tsim cov ntaub ntawv nyuaj. Cov txheej txheem ua haujlwm txias no yuav tsum muaj kev ua haujlwm siab heev, thiab qhov tseeb ntawm cov tshuab thiab kev txawj ntse ntawm cov txheej txheem kev khiav hauj lwm muaj kev cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom kawg.
Kev kho cua sov: optimizing cov khoom hlau
Kev kho cua sov yog ib kauj ruam tseem ceeb hauv cov txheej txheem ntawm kev ua kom lub cev zoo ntawm cov hlau, xws li hardness, toughness thiab hnav tsis kam. Los ntawm kev ua haujlwm cua sov thiab txias xws li quenching, tempering thiab annealing, cov qauv siv lead ua sab hauv ntawm cov hlau tuaj yeem hloov kho los txhim kho nws cov khoom siv kho tshuab. Cov txheej txheem mus dhau tsuas yog cua sov lossis cua txias thiab koom nrog kev tswj xyuas lub sijhawm thiab qhov kub thiab txias kom tau txais txiaj ntsig zoo.
Kev kho deg: txhim kho durability thiab zoo nkauj
Tom qab ua tiav cov txheej txheem ntawm cov khoom hlau tiav, kev kho deg yuav tsum tau ua. Cov txheej txheem no suav nrog electroplating, txau, polishing, thiab lwm yam. Lub hom phiaj yog txhawm rau txhim kho corrosion ntawm cov hlau, txhim kho kev zoo nkauj thiab kev pabcuam lub neej. Piv txwv li, stainless hlau cov khoom feem ntau polished kom tau ib tug kaj nto, los yog plated kom corrosion kuj.
Los ntawm smelting mus rau cov khoom tiav, kev tsim cov khoom siv hlau yuav tsum muaj cov txheej txheem nyuaj thiab cov txheej txheem sophisticated. Txhua kauj ruam muaj nws tus kheej cov kev cai tshwj xeeb, thiab kev tsis saib xyuas hauv ib qho kev nthuav dav tuaj yeem cuam tshuam qhov zoo ntawm cov khoom tiav. Los ntawm cov txheej txheem no, hlau tsis yog cov khoom txias xwb, tab sis yog ib feem tseem ceeb ntawm peb lub neej.
