Txhais thiab qhov sib txawv ntawm cov hlau tsis muaj hlau thiab cov hlau ferrous
Xyoo 1958, Tuam Tshoj tau faib cov hlau, chromium, thiab manganese ua ferrous hlau; nws tau faib 64 hlau uas tsis yog hlau, chromium, thiab manganese ua cov hlau tsis muaj hlau. Dab tsi yog nonferrous hlau? ferrous hlau yog dab tsi, thiab dab tsi yog qhov txawv ntawm cov hlau tsis-ferrous thiab ferrous hlau? Hlau, npua hlau, tooj liab, txhuas, thiab stainless hlau yog tag nrho cov lus paub hauv peb lub neej. Lawv tag nrho yog cov hlau. Qhov twg yog cov hlau tsis muaj hlau thiab cov khoom twg yog cov hlau ferrous. Qee zaum peb tsis tuaj yeem qhia lawv kom meej.
1. Cov hlau uas tsis yog hlau yog dab tsi?
Cov hlau tsis-ferrous hauv qhov nqaim kuj tseem hu ua cov hlau tsis muaj hlau thiab yog cov lus sib sau rau txhua yam hlau tshwj tsis yog hlau, manganese thiab chromium. Nonferrous hlau nyob rau hauv ib tug dav kev nkag siab kuj muaj xws li nonferrous alloys. Non-ferrous alloys yog cov alloys ua los ntawm cov hlau tsis muaj hlau ua lub hauv paus (feem ntau ntau dua 50%) thiab ntxiv ib lossis ob peb lwm yam. 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 siv tswv yim, cov hlau tsis yog hlau feem ntau muab faib ua 5 pawg
1. Lub teeb hlau: qhov ntom tsawg dua 4500 kg / cubic meter, xws li txhuas, magnesium, potassium, sodium, thiab lwm yam.
2. Cov hlau hnyav: qhov ceev ntau dua 4500 kg / m3, xws li tooj liab, npib tsib xee, cobalt, txhuas, zinc, mercury, thiab lwm yam.
3. Cov hlau muaj txiaj ntsig: Lawv feem ntau kim dua cov hlau, muaj cov nplua nuj nyob hauv lub ntiaj teb pob zeb, thiab nyuaj rau ntxuav, xws li kub, nyiaj thiab platinum pawg hlau.
4. Semi-hlau: Qhov xwm thiab tus nqi yog nyob nruab nrab ntawm cov hlau thiab cov hlau tsis muaj hlau, xws li silicon, selenium, tellurium, arsenic, boron, thiab lwm yam.
5. Cov hlau tsis tshua muaj:
1) Cov hlau tsis tshua muaj xws li: lithium, rubidium, cesium, thiab lwm yam;
2) Tsis tshua muaj refractory hlau xws li: titanium, zirconium, molybdenum, tungsten, thiab lwm yam;
3) Tsis tshua muaj dispersed hlau xws li: gallium, indium, germanium, thallium, thiab lwm yam.;
4) Cov hlau tsis tshua muaj hauv ntiaj teb xws li scandium, yttrium, thiab lanthanide series hlau;
5) Radioactive hlau xws li: radium, francium, polonium thiab uranium, thorium, thiab lwm yam nyob rau hauv Al series ntsiab.
2. Dab tsi yog ferrous hlau?
Ferrous hlau yog cov hlau thiab alloys nrog hlau ua qhov tseem ceeb. Tam sim no, ferrous hlau peb feem ntau xa mus rau cov hlau, manganese, manganese thiab alloys. Xws li hlau, npua hlau, stainless hlau, thiab lwm yam yog tag nrho cov hlau ferrous. Hlau thiab npua hlau yog ob qho tib si alloys raws li hlau thiab nrog cov pa roj carbon ua lub ntsiab ntxiv. Lawv raug hu ua hlau-carbon alloys. Npua hlau yog cov khoom tsim los ntawm smelting hlau ore nyob rau hauv lub moj tej tawg rauv thiab yog tsuas yog siv rau steelmaking thiab manufacturing castings. Cov cam khwb cia npua hlau yog muab tso rau hauv lub qhov cub melting thiab smelted kom tau cam khwb cia hlau (kua), thiab ces cov kua cam khwb cia hlau yog poured rau hauv ib tug casting, uas yog hu ua hlau casting. Ferroalloy yog ib qho alloy uas muaj hlau thiab silicon, manganese, chromium, titanium thiab lwm yam khoom. Nws yog ib qho ntawm cov khoom siv raw rau steelmaking thiab yog siv los ua deoxidizer thiab alloying caij additive rau steel thaum steelmaking. Cov npua hlau siv rau steelmaking yog muab tso rau hauv steelmaking rauv thiab ces smelted raws li ib tug tej yam txheej txheem kom thaum kawg tau hlau. Cov khoom siv hlau muaj xws li steel ingots, nruam casting billets thiab ncaj qha casting ntawm ntau yam steel castings. Hlau feem ntau yog hais txog steel dov rau hauv ntau yam khoom steel.
3. Qhov sib txawv ntawm cov hlau tsis muaj hlau thiab ferrous hlau:
Los ntawm kev nkag siab ntawm cov hlau tsis muaj hlau thiab cov hlau ferrous, peb twb paub tias cov hlau ferrous feem ntau yog xa mus rau hlau, complex, manganese thiab alloys. Cov hlau tsis-ferrous suav nrog tag nrho cov hlau thiab lawv cov hlau tsis muaj hlau tshwj tsis yog hlau, manganese thiab chromium. , qhov no yog qhov sib txawv ncaj qha ntawm lawv.
