Lub luag haujlwm ntawm Alloy Steel Sand Casting Elements

Alloy steel yog lub hom phiaj tshwj xeeb hlau tsim los ntawm kev ntxiv qee qhov ntawm cov ntsiab lus alloying rau Fe-C alloy hlau. Alloy steels feem ntau yog cais raws li lawv siv, cov ntsiab lus alloying, metallurgical zoo, thiab lwm yam. Kev faib tawm raws li nws siv, metallurgical zoo, thiab lwm yam zoo ib yam li carbon steel. Tsuas yog qhov kev faib tawm los ntawm cov ntsiab lus alloying yog qhia ntawm no.

1. Kev faib tawm ntawm cov hlau alloy

(1) Raws li tag nrho cov alloying ntsiab lus, tag nrho cov alloy tsawg dua 5 yog hu ua low alloy steel, 5 feem pua ​​tsawg dua los yog sib npaug rau tag nrho cov alloy <10 feem pua ​​yog hu ua medium alloy steel, thiab tag nrho cov alloy loj dua. los yog sib npaug li 10 feem pua ​​yog hu ua high alloy steel.

(2) Raws li lub ntsiab alloying ntsiab, xws li: 3Cr3MoW2V steel yog hu ua chromium tungsten silicon steel.

2. Thawj tus lej ntawm qib ntawm cov hlau alloy qhia cov ntsiab lus carbon wc.

Yog hais tias nws yog ib tug lej, nws yog qhia nyob rau hauv txhiab ntawm wc. Yog tias nws yog ob tus lej, nws tau hais hauv kaum txhiab ntawm wc. Tshawb xyuas cov ntaub ntawv rau tus nqi tshwj xeeb); thaum qhov nruab nrab cov ntsiab lus carbon wc Tsawg dua lossis sib npaug rau {{0}}}.08 feem pua ​​, nws yog sawv cev los ntawm "0", thiab thaum cov ntsiab lus nruab nrab carbon wc Tsawg dua lossis sib npaug rau 0.03 feem pua ​​, nws yog sawv cev los ntawm "00". Tus lej tom qab ib lub ntsiab lus qhia qhov nruab nrab feem pua ​​​​cov ntsiab lus ntawm cov khoom ntawd. Tsis muaj daim duab qhia tias cov ntsiab lus ntawm cov khoom no yog <1.5 feem="">

Siv 8Cr2MnWMoVS ua piv txwv, 8 txhais tau tias wc≈0.8 feem pua, Cr2 txhais tau tias wc≈2 feem pua, thiab cov ntsiab lus ntawm Mn, W, Mo, V, thiab S yog tag nrho.<>

3. Lub luag haujlwm ntawm cov khoom siv feem ntau siv alloying

Tom qab ntxiv cov ntsiab lus alloying rau cov hlau, nws tuaj yeem tsim tau qee yam ntawm cov hlau alloy carbides, ua kom cov nplej zoo dua, txhim kho cov tawv tawv, thiab ua kom lub zog ruaj khov, kom ua tau raws li qhov yuav tsum tau ua ntawm kev hnav tsis kam thiab txhim kho toughness. Lub ntsiab alloying ntsiab ntxiv thiab lawv cov dej num yog raws li nram no:

(1) Lub luag haujlwm ntawm Mn Manganese ua kom muaj zog ntawm cov hlau, txo qhov kub ntawm martensitic hloov pauv ntawm cov hlau, thiab ua kom cov austenite ruaj khov tom qab quenching, uas muaj txiaj ntsig zoo los tiv thaiv quenching deformation, quenching cracking, thiab stabilizing qhov ntev ntawm workpieces. . Tab sis txo cov thermal conductivity ntawm steel, muaj ib tug rhiab heev rau overheating, thiab aggravate ob hom temper brittleness. Mn yuav tsum tau ntxiv rau hauv kev sib xyaw nrog Mo, V, Cr, W, thiab lwm yam. Nws yog txwv tsis pub muaj kev cuam tshuam thiab siab zog thiab toughness tuag steel.

(2) Lub luag hauj lwm ntawm Si: Silicon tsub kom lub hardenability thiab tempering stability ntawm steel, thiab ho txhim khu kev tiv thaiv tom qab deformation thiab cuam tshuam kev qaug zog; nws tuaj yeem txhim kho oxidation tsis kam thiab corrosion kuj ntawm steel. Txawm li cas los xij, silicon txhawb nqa nag lossis daus ntawm cov pa roj carbon monoxide hauv cov hlau hauv daim ntawv ntawm graphite, uas ua rau muaj kev cuam tshuam loj heev rau decarburization, thiab ua rau muaj kev kub ntxhov siab heev thiab qhov thib ob ntawm temper brittleness ntawm cov hlau.

(3) Lub luag hauj lwm ntawm Cr Chromium ho nce lub hardenability ntawm steel thiab zoo txhim kho tempering stability ntawm hlau. Nrog rau qhov nce ntawm cov ntsiab lus carbon hauv cov hlau, carbides xws li (Fe Cr) 3C thiab (Fe Cr) 23C yog tsim nyob rau hauv lem. Cov carbides muaj kev ruaj ntseg zoo dua, yog li txo qhov kub siab ntawm cov hlau thiab txhim kho cov hlau tsis kam. Abrasiveness. Chromium muaj cov nyhuv passivation ntawm cov hlau nto, ua rau cov hlau tiv taus oxidation. Txawm li cas los xij, cov ntsiab lus chromium siab dua nce carbide inhomogeneity thiab cov nyiaj khaws cia austenite. Feem ntau, hauv cov hlau tsis tshua muaj hlau, qhov loj ntawm chromium yog 0.5 feem pua ​​~ 1.5 feem pua; nyob rau hauv siab toughness tuag steel, qhov loj feem ntawm chromium yog 4 feem pua ​​~ 5 feem pua; nyob rau hauv siab hnav-resistant micro-deformation tuag steel, qhov loj feem ntawm chromium 6 feem pua ​​​​rau 12 feem pua.

(4) Lub luag haujlwm ntawm Mo Molybdenum tuaj yeem txhim kho hardenability thiab siab kub creep zog, thiab tempering stability thiab theem nrab hardening nyhuv kuj muaj zog dua cov chromium; thiab tuaj yeem cuam tshuam qhov thib ob ntawm temper brittleness tshwm sim los ntawm Cr, Mn, thiab Si. Tab sis molybdenum nce decarburization nyiam. Qhov loj feem ntawm molybdenum hauv cov hlau tuag yog 0.5 feem pua ​​​​rau 5 feem pua.

(5) Lub luag hauj lwm ntawm W Ib qho ntawm qhov zoo ntawm tungsten yog ua rau cov tawv tawv thib ob, uas ua rau muaj txiaj ntsig zoo ntawm cov hlau kub; nws yog qhov zoo dua li molybdenum hauv kev txhim kho kev hnav tsis kam thiab txo qhov kub siab ntawm cov hlau. Txawm li cas los xij, tungsten tuaj yeem txo cov thermal conductivity ntawm cov hlau, thiab cov tungsten ntau dhau ua rau cov carbide ntawm tungsten tsis sib xws, thiab lub zog thiab tawv ntawm cov hlau txo. Hauv kev ua haujlwm txias tuag steel nrog lub peev xwm siab, qhov loj ntawm tungsten tsawg dua 18 feem pua, thiab Mo thiab V nyiam hloov W thiab txo cov ntsiab lus W.

(6) Lub luag haujlwm ntawm V Vanadium feem ntau muaj nyob hauv cov hlau hauv daim ntawv ntawm V4C3. Vim tias V4C3 ruaj khov thiab insoluble, thiab nws cov hardness siab heev, vanadium tuaj yeem txhim kho qhov hnav tsis kam thiab kub hardness ntawm hlau; Nyob rau tib lub sijhawm, vanadium kuj tseem tuaj yeem ua kom cov nplej zom thiab txo qis kev kub ntxhov. Txawm li cas los xij, vanadium ntau dhau yuav txo qhov forgeability thiab grindability. Yog li ntawd, feem ntau ntawm vanadium feem ntau tswj ntawm 0.2 feem pua ​​​​rau 2 feem pua.

(7) Lub luag haujlwm ntawm Co Lub luag haujlwm tseem ceeb ntawm cobalt yog txhawm rau txhim kho cov tawv tawv liab ntawm cov hlau nrawm thiab ua kom cov nyhuv hardening theem nrab. Hauv cov ntaub ntawv cemented carbide, cobalt yog ib qho tseem ceeb binder.

(8) Lub luag haujlwm ntawm Ni Nickel tuaj yeem tsis tsuas yog txhim kho lub zog ntawm cov hlau, tab sis kuj txhim kho cov tawv tawv ntawm cov hlau, thiab tib lub sijhawm txhim kho cov tawv tawv ntawm cov hlau; Thaum cov ntsiab lus siab, nws tuaj yeem txhim kho corrosion kuj ntawm steel. Txawm li cas los xij, npib tsib xee muaj qhov nyiam ua rau hom thib ob ntawm temper brittleness.

Txhua qib steel hlau yog ib qho kev sib txuas zoo tshaj plaws ntawm cov ntsiab lus alloying thiab cov ntsiab lus alloying. Thaum txheeb xyuas cov khoom thiab cov yam ntxwv ntawm cov hlau alloy, cov ntsiab lus ntawm cov ntsiab lus alloy thiab kev sib xyaw ntawm cov ntsiab lus ntawm cov hlau alloy tuaj yeem raug txheeb xyuas.
