Khoom Taw Qhia

FGS700-2 poob ciab peev casting ntawm ductile hlau

Khoom taw qhia

Khoom npe: hlau hlau

Scope ntawm daim ntawv thov

Nws yog pearlescent ductile hlau nrog lub zog siab, hnav tsis kam thiab tsis tshua muaj zog (tsis tshua muaj plasticity). Tsim nyog rau siab zog yuav tsum tau ntawm qhov chaw, xws li diesel thiab roj av cav crankshaft, camshaft, ib feem ntawm lub grinder, milling tshuab, tshuab dhos spindle, pob zeb ncej, me me turbine spindle.

Tshuaj muaj pes tsawg leeg

C: 3.08 ~ 3.30

Silicon: 2.49 ~ 3.13

Manganese Mn: {0}}.55 ~ 0.61

Sulfur S: {{0}}.017 ~ 0.022

P: 0.045 ~ 0.052

Cov cuab yeej cuab tam

Tensile zog σb (MPa): Ntau dua lossis sib npaug rau 700

Conditional yield zog σ0.2 (MPa): Ntau dua lossis sib npaug rau 420

Elongation δ (%): Ntau dua lossis sib npaug rau 2

Hardness: 225 ~ 305HB

Kev kho cua sov specifications thiab metallographic qauv

Kev kho cua sov specification: (txiav txim siab los ntawm tus neeg muag khoom, cov hauv qab no yog kev kho cua sov ntawm tus qauv, rau kev siv) 800 degree, normalizing

Metallographic qauv: graphite + pearlite + ib qho me me ntawm ferrite

Cov khoom siv hluav taws xob ntawm cov hlua hlau yog nyob ntawm ob qhov ntsuas: tensile lub zog thiab elongation. Raws li cov txheej txheem tsim khoom ruaj khov, kev lees paub kuj tuaj yeem ua raws li tus nqi hardness. Vim hais tias kev sib raug zoo ntawm hardness thiab lub zog yog tsim nyob rau hauv lub hauv paus ntawm tsim nyog spheroidization, tshuaj muaj pes tsawg leeg, inoculation stability, thiab tsim nyog casting txheej txheem, nyob rau hauv thiaj li yuav xyuas kom meej qhov kev ua tau zoo, nws yog stipulated hais tias cov metallographic qauv yuav tsum tau kuaj thaum txais raws li qhov kev thov. hardness, thiab spheroidization tus nqi yuav tsum tsis txhob tsawg tshaj li 4. Txawm hais tias lub hardness thiab spheroidization yog tsim nyog, lub zog thiab toughness yuav tsis tau raws li qhov yuav tsum tau vim muaj cov cementite, phosphorus eutectic thiab siab silicon tov ntxiv dag zog rau hauv matrix. Yog li ntawd, tsis muaj qhov ruaj khov ntawm cov txheej txheem ntau lawm, nws tsis tuaj yeem lees txais raws li tus nqi hardness.
