Kev rov ua dua tshiab ntawm cov hlau pib nrog kev sau cov khoom seem, uas tuaj yeem txo cov peev txheej pov tseg, txo kev siv hluav taws xob thiab txo qis ib puag ncig. Cov tuam txhab rov ua dua tshiab sau cov khoom seem los ntawm kev rhuav tshem lub tsev, tsheb scrapping, thiab sau cov khoom seem ntawm cov txheej txheem steel. Cov khib nyiab hlau yuav tsum tau muab cais tawm kom ntseeg tau tias nws qhov zoo thiab purity, yog li txhim kho qhov ua tau zoo ntawm cov smelting tom ntej.
Cov txheej txheem ntau lawm
Cov seem hlau yog ntxuav mechanically thiab chemically tshem tawm cov roj stains, coatings thiab lwm yam impurities adhering rau saum npoo ntawm cov seem. Nws tau ua kom ntseeg tau tias cov seem hlau yuav tsis muaj kev cuam tshuam tsis zoo rau cov khoom kawg thaum lub sij hawm smelting. Cov khib nyiab huv huv yuav tsum tau txiav rau hauv me me kom yooj yim rau kev thauj mus los thiab smelting.
01
Cov khib nyiab hlau uas tau ntxuav thiab txiav yog xa mus rau qhov cub tawg lossis hluav taws xob arc rauv rau smelting. Hauv qhov cub tawg, cov hlau khib nyiab, nrog rau coke thiab limestone, yog cua sov los ua kom muaj kev kub siab ntawm - cov tshuaj tiv thaiv kub, yog li hloov cov khib nyiab hlau rau hauv cov kua hlau.
02
Thaum lub sij hawm smelting txheej txheem, lub melting ntawm seem hlau tso tawm ib tug loj npaum li cas ntawm tshav kub zog, uas yuav tsum tau recycled thiab siv los txhim kho lub zog efficiency. Cov dej khib nyiab thiab cov pa hluav taws xob tsim tawm thaum lub sijhawm smelting yuav raug kho kom txo tau lawv qhov cuam tshuam rau ib puag ncig.
03
Tom qab cov txheej txheem smelting tiav, cov kua hlau yog cam khwb cia rau hauv ntau yam duab ntawm steel billets. Cov no suav nrog cov phaj, tuav, raj, thiab lwm yam ntaub ntawv, thiab cov duab tshwj xeeb yog nyob ntawm cov txheej txheem tom ntej. Cov steel billets tom qab casting yuav raug cua txias thiab solidification los tsim cov hlau muaj zog.
04
Cov cam khwb cia hlau yuav tsum tau kho cua sov thiab ua haujlwm. Kev kho cua sov tuaj yeem txhim kho lub cev ntawm cov hlau, txhim kho nws lub zog thiab tawv. Cov txheej txheem suav nrog dov, forging, txiav thiab lwm yam txheej txheem, uas hloov cov hlau mus rau hauv cov khoom kawg. Thaum lub sij hawm tsim cov txheej txheem no, cov chaw tsim khoom yuav hloov kho cov txheej txheem thiab cov txheej txheem ntawm cov hlau raws li kev xav tau ntawm kev ua lag luam thiab cov neeg siv khoom kom ntseeg tau tias qhov zoo ntawm cov khoom kawg.
05
Cov txheej txheem ntawm cov hlau rov ua dua tshiab yog ib qho nyuaj tab sis muaj txiaj ntsig zoo hauv lub voj voog, npog los ntawm kev sau, tu, smelting ntawm seem steel, mus rau qhov kawg ua thiab daim ntawv thov. Txhua kauj ruam yog qhov tseem ceeb. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txhim kho ntawm ib puag ncig kev paub, kev siv cov hlau rov ua dua tshiab yuav nthuav dav dua, ua rau muaj txiaj ntsig zoo rau kev ua tiav kev siv cov peev txheej ruaj khov. Los ntawm kev nkag siab txog cov txheej txheem rov ua dua hlau, peb tsis tsuas yog tau txais kev nkag siab zoo ntawm cov khoom tseem ceeb no, tab sis kuj pab txhawb kev lag luam ntsuab thiab kev txhim kho kom ruaj khov.
