Dab tsi yog: Nickel, npib tsib xee hlau, npib tsib xee npua hlau, npib tsib xee-raws li alloys

1.Nickel yog ib qho kev hloov pauv hlau nrog lub cim cim Ni, nyob hauv Pawg VIII ntawm lub voj voog thib plaub, thiab tus lej atomic yog 28. Nickel yog siv rau hauv cov hlau, npib tsib xee-raws li alloys, electroplating thiab roj teeb, thiab yog siv dav. nyob rau hauv ntau yam tub rog manufacturing industries xws li aircraft thiab radar, civil machinery manufacturing thiab electroplating industries. Nickel yog ib qho tseem ceeb raw khoom rau stainless hlau. Cov nickel noj nyob rau hauv Tuam Tshoj txoj kev lag luam stainless hlau account rau ntau tshaj 80% ntawm thawj nickel noj thiab tso zis, thiab lub ntiaj teb no feem ntau tshaj 2/3.

2.Ferronickel Ib qho alloy ntawm hlau thiab npib tsib xee tau los ntawm oxide ores lossis lwm cov ntaub ntawv uas muaj nickel, nrog cov ntsiab lus npib tsib xee ntau dua lossis sib npaug li 15% (feem ntau) thiab tsawg dua 80% (feem ntau). Raws li lub teb chaws tus qauv GB/T25049-2010, ferronickel tuaj yeem muab faib ua tsib pawg: cov pa roj carbon tsawg ferronickel, qis carbon qis phosphorus ferronickel, nruab nrab carbon ferronickel, nruab nrab carbon tsawg phosphorus ferronickel, thiab siab carbon ferronickel.

3.Nickel Pig Iron Cov ntsiab lus nickel ntawm nickel npua hlau yog tsawg dua 15%. Feem ntau, raws li cov ntsiab lus sib txawv nickel hauv nickel npua hlau, nws tuaj yeem muab faib ua qib siab nickel npua hlau (10% thiab siab dua), qib nruab nrab nickel npua hlau (4-9%), thiab qib qis. nickel npua hlau. Nickel npua hlau yog tsuas yog smelted nyob rau hauv submerged arc furnaces thiab blast furnaces. Feem ntau, submerged arc furnaces tsim high-qib npib tsib xee npua hlau, thiab blast furnaces tsim nruab nrab-qib nickel npua hlau. Nickel npua hlau yog ib qho tseem ceeb ntawm nickel raw khoom rau stainless hlau.

4.Nickel-based Alloy Nickel-based alloys xa mus rau alloys raws li nickel (muaj cov ntsiab lus nickel ntau dua lossis sib npaug li 50%) thiab muaj cov ntsiab lus xws li Cr, Mo, Cu, Al, Ti, Nb, thiab lwm yam. Cov khoom tseem ceeb, lawv tau muab faib ua npib tsib xee-raws li kub-resistant alloys, npib tsib xee-raws li corrosion-resistant alloys, npib tsib xee-raws li hnav-resistant alloys, npib tsib xee-raws li precision alloys thiab nickel-raws li cov duab nco alloys. Piv txwv li, Inconel 690, Hatselloy C-276, Haynes 242, Monel 400, Incoloy800 thiab lwm yam nickel-based alloy qib.
