Dej iav Casting txheej txheem

Cov txheej txheem dej iav casting yog ib qho ntawm feem ntau cov peev txheej casting txheej txheem hauv Suav teb, tab sis nws tsis tshua muaj nyob hauv lwm lub tebchaws. Ntawm cov foundries hauv kuv lub teb chaws, kwv yees li 80 feem pua ​​​​ntawm cov foundries feem ntau yog cov iav dej, thiab cov seem yog silica sol foundries.

Dej iav Casting yog ib qho kev poob peev txheej casting uas siv cov iav dej ua cov ntawv khi rau lub plhaub. Cov txheej txheem wax ploj tau tuav qhov chaw casting thiab kev tshuaj xyuas sab hauv ntawm tus nqi qis. Dej iav casting originated nyob rau hauv Russia. Haum rau steel castings, tshwj xeeb tshaj yog carbon steel thiab alloy steel castings. Nws tso cai rau kev tsim cov hlau castings ntawm 0.5kg txog 60kg.

Tom qab ntau tshaj kaum xyoo ntawm nag lossis daus, Qinhuangdao Zhongwei Precision Machinery Co., Ltd. muaj kev paub ntau lawm hauv dej iav poob ciab precision casting, poob ua npuas ncauj precision casting, silica sol precision casting, thiab plhaub xuab zeb casting. Peb cia siab tias cov neeg tsim khoom los ntawm thoob plaws lub ntiaj teb tuaj yeem sab laj thiab sib tham ua lag luam.

Poob Wax Casting Hardening Method Of Water Glass

Hauv kev lag luam kev lag luam casting, dej iav xuab zeb qauv feem ntau yog siv rau kev tsim khoom, thiab qee zaum hardening kho tau ntsib thaum siv cov txheej txheem. Feem ntau muaj ob txoj kev hardening uas feem ntau siv tam sim no:

1. Tej yam yooj yim CO2 roj nyuaj txoj kev

Cov txheej txheem no yog cov txheej txheem ua ntej sai sai siv rau hauv daim ntawv khi, cov cuab yeej siv tau yooj yim thiab kev ua haujlwm yooj yim dua, thiab nws yooj yim dua, thiab tus nqi tsis siab, thiab nws yog siv rau hauv ntau cov hlau casting txheej txheem.

Qhov zoo: Qhov ceev ntawm hardening kuj ceev, thiab lub zog kuj yog siab. Thaum cov pwm raug tshem tawm tom qab hardening, precision ntawm cov khoom yuav siab heev.

Qhov tsis zoo: Lub zog ntawm molding xuab zeb lossis cov xuab zeb tseem ceeb yog qhov tsawg, thiab cov iav dej ntau yuav tsum tau ntxiv; cov ntsiab lus dej yog qhov loj, thiab nws yooj yim rau nqus dej; Nyob rau lub caij ntuj no, lub zog huab cua permeability tsis zoo, uas yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm casting; collapsibility Nws kuj yog qhov tsis zoo, thiab nws yog ib qho nyuaj rau rov tsim cov xuab zeb qub, uas ua rau cov xuab zeb qub raug tshem tawm ncaj qha, uas cuam tshuam rau ib puag ncig.

2. Organic ester self-hardening txoj kev

Cov organic ester hauv cov kua tuaj yeem hloov tau cov roj uas tau hais los saum toj no raws li lub hardener ntawm iav dej.

Qhov zoo: molding xuab zeb los yog core xuab zeb muaj zog hardness, thiab tus nqi ntawm cov iav dej ntxiv tuaj yeem txo qis rau qee yam nqi; lub zog nkag mus rau lub caij ntuj no yog qhov zoo, thiab lub hardening ceev yuav raug kho raws li ib puag ncig; Tus cwj pwm zoo ntawm lub cev qhuav dej, yooj yim los tsim cov xuab zeb ntxuav, thiab cov xuab zeb qub tuaj yeem rov ua dua tshiab, tus nqi rov ua dua yog siab, thiab cov pa phem rau ib puag ncig raug txo; cov xuab zeb molding muaj cov thermoplasticity zoo thiab tsis tshua muaj roj, uas tuaj yeem kov yeej qhov tsis xws luag hauv kev tsim cov castings.

Disadvantages: Lub hardening ceev kuj qeeb thiab fluidity tsis zoo.

Khoom Zoo

1,Txhim kho qhov zoo ntawm qhov chaw

Raws li cov qauv ib txwm muaj, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov castings nrog ib qho ntawm ntau tshaj 20 kilograms, qhov zoo ntawm qhov saum npoo yog qhov nyuaj rau lav, thiab qhov tsis xws luag tshwm sim los ntawm nto burrs, nplaum xuab zeb, saum npoo toad tev, txiv kab ntxwv tev thiab delamination yog unavoidable. . Hauv kev tsim cov khoom tuab thiab loj, qhov saum npoo yuav luag yuav tsum tau ua hauv av kom tau raws li qhov yuav tsum tau ua. Cov mis tshiab daws cov teeb meem saum toj no tag nrho, thiab cov castings ntawm yuav luag tag nrho cov ntaub ntawv (tshwj tsis yog cov uas muaj ntau tshaj 4 feem pua ​​manganese) ncav cuag los yog ntau tshaj qhov sib xyaw plhaub.

2,Zoo heev txhim kho lub sab hauv zoo

Nrog rau cov tshuaj ib txwm muaj, vim lub zog qis ntawm txheej txheej, tom qab lub plhaub raug rho tawm haujlwm, thaum koj kov lub puab phab ntsa ntawm lub plhaub nrog koj txhais tes, cov tshauv dawb feem ntau pom. Yog li ntawd, qhov zoo ntawm lub plhaub saum npoo yog qhov tsis ruaj khov, thiab lub plhaub delamination tshwm sim los ntawm ib ntus; cov xwm txheej no ua rau tsis muaj peev xwm lav tau qhov zoo ntawm qhov casting ntawm cov tsoos dej iav plhaub, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua haujlwm nrog cov kev xav tau siab, feem ntau vim yog kev ua cov xuab zeb. Qhov tsis xws luag xws li qhov ua rau cov scrapping ntawm castings, feem ntau yog tshwm sim los ntawm qhov tsis zoo ntawm lub plhaub, thiab cov qauv tshiab daws qhov teeb meem no tau zoo thiab txhim kho qhov zoo ntawm cov castings.

3,Txhim kho cov txiaj ntsig, tshwj xeeb tshaj yog txhim kho cov txiaj ntsig ntawm cov khoom zoo

Siv cov tshuaj ib txwm siv, vim tias qhov chaw thiab sab hauv zoo tsis tuaj yeem tswj tau qhov kev ntseeg siab, tus nqi seem yog qhov siab. Nrog rau cov qauv tshiab, qhov zoo ntawm qhov chaw thiab sab hauv zoo tau zoo heev, thiab cov txiaj ntsig tau zoo dua qub, tshwj xeeb tshaj yog tsis kho. Thiab tus nqi ntawm cov khoom zoo polished tau zoo heev.

4,Txo qhov ua haujlwm ntawm kev ua haujlwm tom qab ua tiav

Nrog rau cov qauv ib txwm muaj, vim qhov tsis zoo ntawm qhov chaw, kev ua haujlwm ntawm kev ua haujlwm tom qab yog qhov loj heev. Niaj hnub no, nrog kev tsis txaus ntawm kev ua haujlwm, nws nyuaj rau nrhiav cov neeg ua haujlwm tom qab ua haujlwm nrog qhov chaw ua haujlwm tsis zoo. Tom qab siv cov qauv tshiab, kev ua haujlwm ntawm kev ua haujlwm tom qab tau txo qis heev. Tshwj xeeb tshaj yog rau cov khoom tuab thiab loj, qhov ua haujlwm ntawm kev ua haujlwm tom qab tuaj yeem raug txo los ntawm ntau dua 80 feem pua.

5,Zoo heev txhim kho qhov chaw ua haujlwm ntawm lub plhaub rhiav

Nyob rau hauv cov tshuaj ib txwm, feem ntau ntawm cov khaubncaws sab nraud povtseg thiab kev hloov txheej txheej yog hardened nrog ammonium chloride. Thaum lub sij hawm hardening txheej txheem, ammonia roj yuav raug generated, uas yuav ua phem rau ib puag ncig thiab corrode cov cuab yeej. Cov mis tshiab tsis tsim cov roj ammonia thaum lub plhaub ua cov txheej txheem, uas daws qhov teeb meem no zoo heev.

6,Txo cov nqi tsim khoom

Kev xyaum tau pom tias tus nqi ntawm lub plhaub ua yog 30-80 yuan ib tuj siab dua li cov qauv tshuaj, tab sis tus nqi ntawm kev ua tom qab tau txo qis heev.

Xya: Txhim kho lub peev xwm ntawm cov tsoos dej iav plhaub los tsim cov khoom loj.

Rau cov tsoos dej iav plhaub, cov khoom loj dua, cov teeb meem ntau dua thiab nyuaj dua nws yog tsim. Nrog rau cov qauv tshiab, ntau yam teeb meem raug daws, thiab lub peev xwm ntawm cov tsoos dej iav plhaub los tsim cov khoom loj lossis cov khoom loj ntxiv tau zoo tuaj.
