Peb lub tuam txhab tau nruab nrog cov cuab yeej tsim khoom siab tshaj plaws thiab cov txheej txheem kev sim, ntsuas ua ntej lub cub tawg, cov cuab yeej kuaj tom qab cub tawg, thiab spectrometer imported los ntawm lub teb chaws Yelemees kom raug txheeb xyuas cov tshuaj muaj pes tsawg leeg thiab lub cev ntawm castings. Main ntau lawm: zoo tib yam dawb cam khwb cia hlau, tsawg alloy dawb cam khwb cia hlau, nruab nrab alloy dawb cam khwb cia hlau, siab alloy dawb cam khwb cia hlau thiab lwm yam accessories.

Kev faib tawm ntawm cov hlau cam khwb cia dawb

1. Dawb cam khwb cia hlau

Dawb cam khwb cia hlau feem ntau muaj 2.0 feem pua ​​~ 3.6 feem pua ​​C, 0.5 feem pua ​​~ 1.9 feem pua ​​Si, 0.25 feem pua ​​~{{10}} .8 feem pua ​​Mn, 0.06 feem pua ​​~0.2 feem pua ​​S, 0.06 feem pua ​​~ 0.2 feem pua ​​P, thiab tus so yog Fe. Dawb cam khwb cia hlau tuaj yeem tsim los ntawm kev ntxiv cov ntsiab lus alloying Cr, Mo, Cu, Al, thiab lwm yam. Thaum lub sij hawm solidification, raws li Fe-Fe3C daim duab qhia theem, tsis muaj graphite yog precipitated. Tsuas yog ib qho me me ntawm cov pa roj carbon diluted hauv ferrite, feem ntau ntawm cov pa roj carbon muaj nyob hauv cov hlau cam khwb cia hauv daim ntawv ntawm cementite. Lub microstructure yog txiav txim siab los ntawm cov tshuaj muaj pes tsawg leeg thiab cov cua txias. Thaum tus nqi txias yog loj txaus, lub microstructure yog dawb cam khwb cia hlau. Nrog rau qhov txo qis ntawm cov cua txias, lub microstructure ntawm cam khwb cia hlau hloov mus rau hemp cam khwb cia hlau, pearlitic grey cam khwb cia hlau, pearlitic ferritic grey cam khwb cia hlau thiab ferritic grey cam khwb cia hlau. Dawb cam khwb cia hlau muaj ntau cov carbide dawb, nrog siab hardness, HB siab tshaj 500, thiab tsis zoo toughness. Hauv kev tsim cov hlau castings, nws yuav tsum tsis txhob muaj pitting lossis lub qhov ncauj dawb. Dawb cam khwb cia hlau tsuas yog siv los ua cov khoom ua liaj ua teb hnav-tiv taus, sib tsoo pob, hniav, twj, chais, thiab lwm yam. Feem ntau yog siv rau kev tsim cov hlau cam khwb cia hlau thiab ua raw khoom rau steelmaking.

2. Ordinary dawb cam khwb cia hlau

Raws li thaum ntxov caij nplooj ntoos hlav thiab lub caij nplooj zeeg, Tuam Tshoj ua dawb cam khwb cia hlau nrog zoo hnav tsis kam thiab siv nws ua ib co anti-hnav qhov chaw. Cov cam khwb cia hlau no muaj cov yam ntxwv ntawm cov pa roj carbon ntau thiab tsis tshua muaj silicon, siab hardness, tab sis nkig heev, tsim nyog rau kev tsim khoom nrog cov khoom me me, feem ntau siv hauv ploughshares, sib tsoo discs, phau ntawv qhia, thiab lwm yam. txhim kho nws cov kev ua tau zoo thiab nthuav dav nws daim ntawv thov ntau yam. Carbon plays lub luag haujlwm tseem ceeb tshaj plaws hauv kev hnav tsis kam ntawm cov hlau cam khwb cia zoo tib yam. Qhov siab dua cov ntsiab lus carbon, ntau cementite yog tsim, tsim ib tug loj npaum li cas ntawm ledeburite, yog li lub hardness ntau dua, qhov zoo dua hnav kuj. . Txawm li cas los xij, qhov siab dua cov ntsiab lus carbon, qhov qis dua qhov toughness. Qhov kom muaj nuj nqis thiab kev faib tawm ntawm cov cementite yuav tsum raug xaiv raws li kev ua haujlwm tshwj xeeb ntawm ib feem. Feem ntau, qhov nyuaj ntawm cov hlau cam khwb cia hlau dawb muaj ib qho kev sib raug zoo nrog cov ntsiab lus carbon, uas yog, HS=16.7C ntxiv rau 13 (HS-Shore hardness; C-Carbon cov ntsiab lus feem pua).

3. Tsawg alloy dawb cam khwb cia hlau

Ntxiv me me ntawm cov ntsiab lus alloying rau cov hlau cam khwb cia zoo tib yam tuaj yeem txhim kho microhardness ntawm carbides thiab ntxiv dag zog rau cov hlau matrix, yog li txhim kho kev hnav tsis kam. Dawb cam khwb cia hlau uas muaj chromium, molybdenum, tooj liab thiab lwm yam ntsiab lus feem ntau yog smelted nyob rau hauv ib lub khob, thiab feem ntau yog siv nyob rau hauv lub xeev-cam khwb cia, yog li tus nqi qis. Txawm li cas los xij, cov carbides hauv cov qauv metallographic ntawm cov hlau cam no tseem txuas ntxiv txuas ntxiv, yog li cov brittleness tseem loj heev, thiab nws yog qhov tsim nyog rau qee lub sijhawm uas yuav tsum tau hnav tsis kam thiab toughness tsis siab dhau. Ntxiv 0.15 feem pua ​​​​rau 0.55 feem pua ​​​​ntawm boron, cov boron feem ntau nkag mus rau carbide, uas tuaj yeem txhim kho qhov hnav tsis kam.

4. Nruab nrab alloy dawb cam khwb cia hlau

Nrog chromium ua lub ntsiab alloying, thaum tus nqi ntawm chromium ntxiv mus txog 9 feem pua, (Cr, Fe) 7C3 carbide tshwm nyob rau hauv cov qauv, thiab nws hardness yog siab li 1300-1800HV. Cov carbide no yog nyob rau hauv daim ntawv ntawm ib tug cais pas nrig los yog phaj, tsis zoo continuity, yog li nws muaj zoo toughness thiab siab zog. Ntxiv nrog rau chrome, nruab nrab alloy dawb cam khwb cia hlau kuj muaj:

(1) Nickel hard dawb cam khwb cia hlau, qib ntawm International Nickel Company yog Ni-Hard 1, 2, 3, thiab 4. Cov ntsiab lus nickel feem ntau yog 3 feem pua ​​​​thiab 5 feem pua, thiab cov ntsiab lus chromium tuaj yeem muab faib ua ob hom. 2% Cr thiab 9% Cr. Lub qub carbide yog (Fe, Cr) 3C, nrog ib tug hardness ntawm 1100-1150HV, uas yog 900-1000HV siab tshaj Fe3C. Cov tom kawg yog feem ntau (Cr, Fe) 7C3 nrog hardness siab dua. Ni-Hard1, 2, thiab 3 tag nrho muaj 2 feem pua ​​​​Cr. Qhov sib txawv tsuas yog vim qhov sib txawv ntawm cov ntsiab lus carbon. Cov pa roj carbon ntau muaj qhov hnav tsis zoo thiab tsis muaj zog; qis carbon yog qhov opposite. International Nickel Corporation tseem muaj ob yam khoom tshwj xeeb: cov pa roj carbon Ni-Hard4 siab, uas muaj kev hnav tsis kam thiab tsis tshua muaj kev cuam tshuam lub neej qaug zog; Lwm cov boron-muaj Ni-Hard1, nrog cov ntsiab lus boron ntawm 0.25 feem pua ​​​​rau 1. castings nrog kuj yooj yim shock loads.

(2) Manganese dawb cam khwb cia hlau muaj cov ntsiab lus siab manganese uas inhibits pearlite thiab stabilizes austenite. Ib qho nyiaj ntawm martensite tshwm nyob rau hauv cov qauv, tab sis muaj ntau khaws cia austenite. Cov ntsiab lus manganese ntawm cov cam khwb cia hlau no yog 5 feem pua ​​​​mus rau 8 feem pua, thiab tus nqi qis, tab sis qhov hnav tsis kam yog tsawg thiab kev ua haujlwm casting kuj tsis zoo.

(3) Manganese-tungsten dawb cam khwb cia hlau, Tuam Tshoj manganese-tungsten No. 1 hnav-resistant cam khwb cia hlau yog siv rau qhov chaw uas yuav tsum tau machining; manganese-tungsten No. 2 hnav-resistant cam khwb cia hlau muaj zog dua. Feem ntau ob leeg yog siv nyob rau hauv lub xeev as-casting.

(4) Tungsten-chromium dawb cam khwb cia hlau, muaj peb qib ntawm W5Cr4, W9Cr6 thiab W16Cr2 nyob rau hauv Suav teb, uas yog tsuas yog siv rau lub sij hawm uas muaj kev cuam tshuam loj load, low-stress erosion abrasive hnav thiab high-stress sib tsoo abrasive hnav. Cov ntawv thov raug txwv vim tus nqi siab ntawm tungsten.

(5) Nruab nrab-chromium dawb cam khwb cia hlau, Ni-Hard4 yog ib qho nruab nrab-chromium dawb cam khwb cia hlau, uas yuav tsum tau ntxiv ntau cov npib tsib xee muaj nuj nqis. Yuav kom txuag tau, tib lub hom phiaj tuaj yeem ua tiav los ntawm kev siv tooj liab, molybdenum thiab manganese ua ke alloying. Nws cov khoom siv tshuab zoo ib yam li Ni-Hard4.

5. High alloy dawb cam khwb cia hlau

Feem ntau siv yog high-chromium dawb cam khwb cia hlau nrog cov ntsiab lus chromium ntawm 12 feem pua ​​​​rau 20 feem pua ​​​​, uas cov ntaub ntawv (Cr, Fe) 7C3 carbides hauv cov qauv. High-chromium dawb cam khwb cia hlau yog feem ntau raug rau high-temperature kho cua sov kom precipitate theem nrab carbides, thiab austenite transforms rau hauv martensite thaum txias. High-chromium dawb cam khwb cia hlau yog dav siv nyob rau hauv qhuav sib tsoo, xws li hlau-ua moj tej tawg rauv nqi khob thiab chute liners. American Climax Molybdenum Company muaj ob qib: 15-3 (muaj 15 feem pua ​​Cr-3 feem pua ​​Mo) thiab 15-2-1 (muaj 15 feem pua ​​Cr-2 feem pua ​​Mo-1 feem pua Cu). 15-3 muab faib ua ultra-high carbon, siab carbon, nruab nrab carbon thiab tsawg carbon raws li qib ntawm cov ntsiab lus carbon. Cov pa roj carbon tsawg muaj qhov zoo toughness thiab tsis tshua muaj hardness, uas yog haum rau lub sij hawm uas muaj feem cuam tshuam loj; cov pa roj carbon ntau yog siv rau lub sijhawm uas muaj kev cuam tshuam me me, uas qhia txog kev hnav zoo.
