Taw qhia

Hauv kev tsim khoom tsim, ntau yam teeb meem zoo li teeb meem casting.

Tab sis qhov tseeb, lawv yogteeb meem xuab zeb.

Deg tsis xws luag

Pwm tawg

Gas porosity

Dimensional sib txawv

Tom qab cov teeb meem no, ib qho tseem ceeb yog qhov tseem ceeb:

👉 Xuab zeb zoo

Thiab xuab zeb zoo nyob ntawm ib lub tshuab:

👉 Roller Hom Ntsuab Sand Tov Khoom Tshuab

Lub tshuab no ncaj qha tswj xyuas seb cov xuab zeb, bentonite, dej, thiab cov khoom ntxiv sib xyaw li cas. Yog tias sib tov tsis sib xws, tsis muaj lub tshuab molding tuaj yeem kho qhov teeb meem tom qab.

1 Dab tsi yog Cov Roller Hom Ntsuab Sand Tov Khoom Tshuab

A Roller Hom Ntsuab Sand Tov Khoom Tshuabyog ib txwm siv tab sis muaj kev ntseeg siab heev ntawm cov cuab yeej siv hauv kev npaj cov xuab zeb ntsuab.

Nws siv:

hnyav rollers → compaction

plows → tig thiab sib tov

los xyuas kom meej uniform faib ntawm:

ya raws

av nplaum binder

tshuaj ntxiv

Lub hom phiaj kawg yog kom ua tiav qhov ruaj khov molding xuab zeb.

Kev npaj xuab zeb thiab kev sim feem ntau yog coj los ntawm:

American Foundry Society

ISO 13503-2

2 Vim li cas Sand Quality Matters hauv Casting

Cov xuab zeb zoo tsis yog "cov xuab zeb sib xyaw".

Nws yuav tsum ua tau raws li ntau yam kev cai:

Yog tias xuab zeb tsis ruaj khov:

👉 tsis zoo nce
👉 tsis kam lees nce
👉 nqi nce

Qhov no yog vim li cas cov xuab zeb ruaj khov yog qhov tseem ceeb.

3 Txoj Cai Ua Haujlwm

Cov menyuam hom kev tov khoom ua haujlwm los ntawm peb qhov ua ke ua ke:

Rolling

Heavy rollers tsoo cov xuab zeb thiab cov khoom me me.

Tig

Plows tsis tu ncua txav xuab zeb kom ntseeg tau tias sib xyaw ua ke.

Txiav

Shear force activates bentonite thiab faib cov dej noo sib npaug.

Txheej Txheem Flow

Xuab zeb nkag mus rau hauv lub lauj kaub sib tov

Rollers siv siab

Dej thiab tshuaj ntxiv ntxiv

Plows sib tov tsis tu ncua

Uniform xuab zeb tawm

Cov txheej txheem no ua kom ntseeg tauzoo ib yam thiab repeatable xuab zeb zoo.

4 Qhov Zoo Tshaj Plaws

4.1 Txhim kho Sand Uniformity

Kev faib tawm ntawm cov dej thiab cov ntaub ntawv sib xws ua rau:

ruaj khov pwm lub zog

zoo dua nto zoo

tsawg dua

4.2 Txhim kho Casting Performance

Zoo xuab zeb ncaj qha txhim kho:

qhov tseeb

casting nto tiav

tswj tsis raug

4.3 Kev ntseeg siab

Cov qauv yooj yim txhais tau tias:

tsawg tsis ua hauj lwm tus nqi

ruaj khov ua haujlwm

lub neej ua haujlwm ntev

4.4 Tus nqi -Kev daws teeb meem zoo

Piv nrog rau cov khoom sib xyaw ua ke, cov menyuam sib tov muaj:

qis peev

yooj yim txij nkawm

kev ua tau zoo

5 Yam Kev Ntsuas Kev Ntsuas

Hauv qab no yog cov qauv ntsuas rau nruab nrab - lub tshuab muaj peev xwm.

Cov txiaj ntsig no yuav tsum tau hloov kho raws li qhov chaw tsim khoom.

6 Kev Ua Zoo Tshaj Plaws los txhim kho cov xuab zeb zoo

Los ntawm kev ua haujlwm tiag tiag:

Tswj Moisture Precisely

Hom phiaj:3.0–4.5%

Zam kev hloov pauv

Txawm me me variation cuam tshuam pwm zoo.

Khaws lub sijhawm sib xyaw kom zoo

Luv luv → tsis sib xws

Ntev dhau lawm → lub zog pov tseg

Pom zoo:

👉 3–6 feeb

Tswj cov xuab zeb kub

Kub kub txo cov binder zoo.

Khaws hauv qab no:

👉 45 degree

Siv cov khoom siv ruaj khov

zoo sib xws xuab zeb grain loj

ruaj khov bentonite zoo

tswj additive input

7 Kev tu kom ruaj khov

Txhua hnub

huv tov khoom

check dej system

Kev saib xyuas zoo=ruaj khov ntau lawm.

8 Thaum twg Koj Yuav Tsum Txhim Kho Koj Cov Khoom Sib Tw?

Xav txog kev kho dua tshiab yog tias:

xuab zeb zoo tsis ruaj khov

siab tsis lees paub

sib tov lub sij hawm ntev heev

muaj peev xwm ntau lawm tsis txaus

Upgrading tov khoom feem ntau txhim kho tag nrho cov kab ntau lawm.
