Ironmaking: Blast Furnace yog cov khoom siv tseem ceeb.
Nyob rau hauv cov txheej txheem ironmaking, lub qhov cub tawg tau dav lees paub tias yog cov khoom siv tseem ceeb tshaj plaws. Nws yog cov cuab yeej tseem ceeb rau kev hloov cov hlau ore rau hauv npua hlau, thiab yog lub hauv paus ntawm tag nrho cov txheej txheem steel ntau lawm, txiav txim siab qhov ruaj khov ntawm npua hlau mov thiab lub hauv paus ntawm cov zis. Lub qhov cub tawg muab cov ntaub ntawv raw rau cov theem tom ntej steelmaking; nws qhov kev kaw yuav ncaj qha ua rau muaj kev cuam tshuam ntau lawm.
Steelmaking: Converter yog cov khoom tseem ceeb hauv cov txheej txheem tseem ceeb.
Nyob rau hauv niaj hnub mainstream converter steelmaking txheej txheem, lub converter yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv. Nws lees paub cov txheej txheem tseem ceeb ntawm kev tshem tawm impurities los ntawm cov hlau molten thiab ua kom zoo rau hauv cov hlau molten uas tsim nyog. Nws yog cov cuab yeej tseem ceeb hauv qib steelmaking ntawm tam sim no loj - nplai steel ntau lawm.
Txhawb Cov Khoom Siv Core
Dhau li ntawm cov cuab yeej tseem ceeb rau kev smelting ncaj qha, ob peb lwm yam khoom txhawb nqa tseem ceeb ua lub luag haujlwm txiav txim siab hauv kev ruaj ntseg hauv cov khoom siv hlau:
- Metallurgical ceev reducers: Raws li cov khoom siv kis tau tus mob hauv cov txheej txheem tseem ceeb xws li kev hloov pauv tilting, lawv yog qhov tseem ceeb rau kev ua haujlwm xws li hloov pauv molten hlau ntxiv, steel tapping, thiab them nyiaj ncaj qha, ua kom ruaj khov thiab muaj peev xwm ntawm cov kab ntau lawm. Lawv raug suav hais tias yog cov cuab yeej sib kis tseem ceeb hauv cov txheej txheem steel.
- Metallurgical hydraulic thooj voos kheej kheej: Paub tias yog "hnyav- lub siab lub luag haujlwm" ntawm kev lag luam steel, lawv tsav cov kev txav tseem ceeb hauv cov txheej txheem tseem ceeb xws li nruam casting thiab dov, ua kom muaj kev ua haujlwm tsis tu ncua thiab ruaj khov ntawm cov kab ntau lawm. Lawv yog cov cuab yeej tseem ceeb rau cov lag luam metallurgical kom tsis txhob muaj kev pheej hmoo poob qis.
- Cov hauv paus hniav tshuab: Raws li cov cuab yeej siv cua hauv nruab nrab, lawv muab cov cua ruaj khov rau ntau theem xws li tawg rau qhov cub tawg, hloov pauv nplawm, thiab ua kom txias tas li. Lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev tsim khoom thiab cov khoom zoo.
