Cov lus hais txog Ferrous Hlau

Hlau yog ib yam khoom uas muaj luster, zoo hluav taws xob conductivity, thermal conductivity thiab mechanical zog, thiab muaj ib tug zoo kub coefficient ntawm kuj. Hlau yog tsev neeg loj, muaj 86 hom hlau nyob hauv ntiaj teb. Feem ntau, raws li cov yam ntxwv ntawm cov xim thiab qhov xwm txheej ntawm cov hlau, cov hlau tau muab faib ua ob pawg: cov hlau dub thiab cov hlau tsis muaj hlau. ferrous hlau tsuas yog xa mus rau hlau thiab nws cov alloys, xws li hlau, npua hlau, ferroalloy, cam khwb cia hlau, thiab lwm yam. Cov hlau uas tsis yog ferrous hlau yog hu ua non-ferrous hlau.

Khoom Description

Ferrous hlau cov ntaub ntawv tau sau npe hu ua hlau, chromium thiab manganese hauv kev lag luam. Nws kuj suav nrog cov alloys ntawm peb cov hlau, tshwj xeeb tshaj yog alloy ferrous steel thiab hlau. Qhov opposite ntawm ferrous hlau yog non-ferrous hlau. Qhov tseeb, cov hlau ntshiab thiab chromium yog nyiaj-dawb, thaum manganese yog silver-grey. Txij li qhov saum npoo ntawm cov hlau feem ntau yog them nrog ib txheej ntawm cov ferric oxide dub, manganese thiab chromium feem ntau yog siv rau hauv cov smelting dub alloy hlau. Yog vim li cas nws thiaj li "misclassified" raws li ib tug dub hlau.

Kev faib tawm ntawm cov hlau ferrous kuj tseem muaj qhov tseem ceeb, vim tias peb cov hlau no yog cov khoom siv tseem ceeb rau smelting steel, thiab steel tuav txoj haujlwm tseem ceeb hauv kev lag luam hauv lub tebchaws, thiab tseem yog ib qho tseem ceeb ntawm kev ntsuas lub teb chaws lub zog. Kev tsim cov hlau ferrous suav txog li 95% ntawm lub ntiaj teb tag nrho cov hlau tsim.

intro

►Cov ntsiab lus mining

Lub npe ferrous hlau thiab non-ferrous hlau feem ntau ua rau tib neeg to taub yuam kev tias ferrous hlau yuav tsum yog xim dub, tab sis nws tsis yog. Tsuas muaj tsib ferrous hlau: hlau, manganese, chromium, vanadium thiab titanium. Thiab tsis muaj leej twg yog cov dub! Cov hlau ntshiab yog silvery dawb; Chromium yog silvery dawb; Manganese yog dawb dawb. Vim tias qhov chaw ntawm cov hlau feem ntau yog xeb, npog nrog cov xim dub ferric oxide thiab tan hlau oxide, nws zoo li dub. Yog li ntawd tib neeg hu nws "dub hlau". Feem ntau hais tias "ferrous metallurgy kev lag luam", feem ntau yog hais txog kev lag luam hlau thiab hlau. Vim tias cov hlau alloy feem ntau yog manganese steel thiab chromium steel, manganese thiab chromium kuj suav tias yog "dub hlau".

► Classification ntawm cam khwb cia hlau:

Ferrous hlau cov ntaub ntawv tau sau npe hu ua hlau, chromium thiab manganese hauv kev lag luam. Nws kuj suav nrog cov alloys ntawm peb cov hlau, tshwj xeeb tshaj yog hlau alloy thiab hlau. Qhov opposite ntawm ferrous hlau yog non-ferrous hlau. Qhov tseeb, cov hlau ntshiab thiab chromium yog nyiaj-dawb, thaum manganese yog silver-grey. Txij li qhov saum npoo ntawm cov hlau feem ntau yog them nrog ib txheej ntawm cov ferric oxide dub, manganese thiab chromium feem ntau yog siv rau hauv cov smelting dub alloy hlau. Yog vim li cas nws thiaj li "misclassified" raws li ib tug dub hlau.
