Xyoo 1958, Tuam Tshoj suav nrog hlau, chromium thiab manganese ua ferrous hlau; 64 hlau uas tsis yog hlau, chromium thiab manganese tau suav nrog cov hlau tsis muaj hlau. Dab tsi yog cov hlau tsis-ferrous? Dab tsi yog ferrous hlau thiab dab tsi yog qhov txawv ntawm nonferrous thiab ferrous hlau? Hlau, npua hlau, tooj liab, txhuas, stainless hlau, cov no yog cov lus paub ntawm peb lub neej, uas yog cov hlau, uas yog cov hlau tsis muaj hlau, uas yog ferrous hlau, qee zaum peb yuav tsis meej.
Ua ntej, dab tsi yog cov hlau tsis-ferrous?
Qhov kev nkag siab nqaim ntawm cov hlau tsis muaj hlau, tseem hu ua cov hlau tsis muaj hlau, yog cov lus sib sau rau txhua yam hlau uas tsis yog hlau, manganese thiab chromium. Kev nkag siab dav ntawm cov hlau tsis muaj hlau kuj suav nrog cov hlau tsis muaj hlau. Non-ferrous alloy yog cov hlau tsis-ferrous ua lub hauv paus (feem ntau ntau dua 50%), ntxiv ib lossis ob peb lwm cov ntsiab lus thiab cov ntsiab lus ntawm cov alloy. Yog li ntawd, cov hlau uas tsis yog-ferrous yog tag nrho cov hlau uas tsis yog hlau, manganese thiab chromium thiab lawv cov alloys uas tsis yog-ferrous.
Hauv kev xyaum, cov hlau tsis-ferrous feem ntau muab faib ua 5 pawg
1, lub teeb hlau: ntom tsawg dua 4500 kg / m3, xws li txhuas, magnesium, potassium, sodium thiab lwm yam.
2, hnyav hlau: ceev ntau dua 4500 kg / m3, xws li tooj liab, npib tsib xee, cobalt, txhuas, zinc, mercury thiab lwm yam.
3, precious hlau: tus nqi yog kim tshaj li qhov feem ntau ntawm cov hlau, tsis tshua muaj abundance ntawm crust, purification nyuaj, xws li kub, nyiaj thiab platinum pab pawg neeg hlau.
4, semi-metallic: xwm ntawm tus nqi ntawm cov hlau thiab tsis-hlau, xws li silicon, selenium, tellurium, arsenic, boron, thiab lwm yam.
5, tsis tshua muaj hlau:
(1) Cov hlau tsis tshua muaj xws li: lithium, rubidium, cesium, thiab lwm yam.
(2) tsawg refractory hlau xws li: titanium, zirconium, molybdenum, tungsten thiab hais txog;
(3) tsawg dispersed hlau xws li: gallium, indium, germanium, thallium thiab hais txog;
(4) Cov hlau tsis tshua muaj hauv ntiaj teb xws li: scandium, yttrium, lanthanum hlau;
(5) radioactive hlau xws li: radium, francium, polonium thiab ib qho system ntawm cov ntsiab lus hauv uranium, thorium thiab lwm yam.
Qhov thib ob, ferrous hlau yog dab tsi?
ferrous hlau yog hlau thiab alloys nrog hlau raws li cov ntsiab lus tseem ceeb, tam sim no peb feem ntau hais ferrous hlau feem ntau yog hais txog hlau, complex, manganese thiab alloys. Xws li hlau, npua hlau, stainless hlau, thiab lwm yam yog ferrous hlau. Hlau thiab npua hlau yog ua los ntawm cov hlau, carbon raws li cov ntsiab lus ntxiv ntawm cov hlau, sib sau ua ke hu ua hlau-carbon alloys. Npua hlau yog cov hlau ore rau hauv qhov cub tawg smelting khoom, feem ntau yog siv hauv steelmaking thiab manufacturing castings. Casting npua hlau rau hauv qhov cub hlau smelting, tau cam khwb cia hlau (kua), nyob rau hauv cov kua cam khwb cia hlau casting rau hauv castings, cov cam khwb cia hlau no hu ua cam khwb cia hlau. Ferroalloy yog tsim los ntawm hlau thiab silicon, manganese, chromium, titanium thiab lwm yam khoom ntawm cov hlau, nws yog ib qho ntawm cov khoom siv raw rau steelmaking, steel hauv steelmaking deoxidizer thiab alloying cov khoom ntxiv. Cov npua hlau siv rau kev ua hlau yog muab tso rau hauv cov hlau ua rauv thiab tom qab ntawd smelted raws li qee yam thev naus laus zis, thiab thaum kawg steel tau txais. Cov khoom siv hlau yog ingots, nruam casting billets thiab ncaj qha mus rau hauv ntau yam steel castings. Feem ntau hu ua steel, feem ntau yog hais txog cov hlau dov rau hauv ntau yam hlau.
Thib peb, qhov sib txawv ntawm cov hlau tsis muaj hlau thiab ferrous:
Los ntawm kev paub txog cov hlau uas tsis yog-ferrous thiab ferrous hlau, peb twb paub lawm: ferrous hlau feem ntau yog hais txog hlau, complex, manganese thiab alloys. Thiab tsis yog-ferrous hlau ntxiv rau hlau, manganese, chromium, tag nrho cov hlau thiab lawv cov tsis-ferrous alloys. Qhov no yog qhov sib txawv ncaj qha ntawm lawv.
