Taw qhia
Nickel hlau yog ib qho alloy ntawm npib tsib xee thiab hlau, uas muaj carbon, silicon, phosphorus, thiab lwm yam. Nickel hlau yog tsuas yog siv los ua tus neeg sawv cev alloying nyob rau hauv smelting ntawm stainless hlau.
Smelting txheej txheem
Muaj peb txoj hauv kev tseem ceeb rau kev tsim cov nickel hlau siv cov xuab zeb nickel ore: blast furnace method, rotary kiln direct reduction method, and rotary kiln submerged arc furnace together method.
- Blast cub tawg smelting
Cov txheej txheem tseem ceeb ntawm kev tsim cov nickel hlau hauv qhov cub tawg yog: ore ziab thiab tshuaj ntsuam (loj thaiv crushing) - batching - sintering - ntxiv sintered ore, coke blocks thiab fluxes nyob rau hauv lub blast furnace rau smelting - cam khwb cia hlau nickel hlau rau hauv ingots thiab slag dej. quenching - tsim cov nickel hlau ingots thiab dej-quenched slag.
- Rotary kiln direct txo smelting
Rotary kiln ncaj qha txo smelting yog dav lees paub tias yog txoj kev tsim khoom nrog qis qis zog noj thiab tus nqi. Cov txheej txheem yooj yim yog: raw ore ziab (loj ore crushing thiab sib tsoo) - ntxiv txo cov thee thiab flux - ntxiv rau hauv lub qhov cub tawg kom txo tau thiab smelting-melting block dej quenching - dej-quenched slag thiab npib tsib xee hlau particle crushing, sib tsoo, Sib nqus sib cais - ua cov nickel hlau hais thiab nplua slag. Cov txheej txheem no tsis tas yuav coke, siv hluav taws xob ntau, muaj cov txheej txheem tsawg, thiab muaj kev sib tw muaj zog thiab muaj zog. Tam sim no, cov txheej txheem no tsis tau pom zoo rau kev tsim khoom loj hauv Suav teb, feem ntau yog vim qhov tsis tiav ntawm cov teeb meem xws li batching, refractory cov ntaub ntawv, thiab lub nplhaib tsim.
- Rotary kiln - submerged arc rauv smelting
Rotary kiln - submerged arc rauv smelting txheej txheem yog dav siv nyob rau hauv ob qho tib si domestically thiab txawv teb chaws rau zus tau tej cov nickel hlau alloys nrog siab nickel ntsiab lus. Ua tiav cov txheej txheem ntawm smelting yog raws li nram no: ziab ntawm raw ore thiab crushing ntawm loj blocks - kom qhuav thiab ua ntej txo cov thee thiab flux mus rau hauv lub teb kiln - txo smelting nyob rau hauv lub submerged arc rauv - casting molten nickel hlau rau hauv ingots thiab dej quenching slag. - tsim cov nickel hlau ingots (los yog dej quenching rau hauv nickel hlau hais) thiab dej quenched slag.
