Cov teeb meem hauv casting tin bronze bushings feem ntau suav nrog cov hauv qab no:
1. Casting defects: Feem ntau tsis xws luag nyob rau hauv tin bronze casting muaj xws li pores, pinholes, kab tom los yog lub zos blackening ntawm lub casting nto, tin hws los yog lead hws, slag inclusions, segregation, shrinkage kab noj hniav, shrinkage, txias kaw, thiab lwm yam. Cov kev tsis zoo no yuav muaj ntau yam xws li cov hlau alloy ua kua huab cua nqus, tsis tsim nyog rau kev tswj qhov kub thiab txias, cov dej noo ntau dhau los yog cov ntsiab lus impurity nyob rau hauv molding xuab zeb, thiab tsis tsim nyog pouring system tsim.
2. Qhov tshwm sim ntawm kev sib cais rov qab: Tin bronze nws tus kheej muaj cov yam ntxwv ntawm kev sib cais rov qab, uas yog, thawj qhov condensed muaj ntau dua ntawm cov tin-melting-point tin ntau dua, thiab tom qab ntawd condensed ib feem muaj qis dua ntawm tin. Qhov tshwm sim no tuaj yeem ua rau lub zog thiab dej siab tsis kam ntawm cov casting kom txo.
3. Shrinkage teeb meem: Tin bronze muaj qhov dav crystallization kub ntau, condenses nyob rau hauv ib tug nplaum lub xeev, thiab nws yog ib qho yooj yim rau shrinkage defects. Shrinkage yuav txo cov khoom siv dag zog thiab qhov ntom ntom ntawm cov casting, cuam tshuam rau nws lub neej kev pabcuam thiab kev nyab xeeb.
4. Casting txheej txheem tswj: Casting
tin bronze tooj liab bushingsyuav tsum muaj kev tswj xyuas cov txheej txheem tsis xws li melting kub, pouring ceev, txias ceev, thiab lwm yam los xyuas kom meej qhov zoo thiab stability ntawm castings. Tsis tas li ntawd, kev tsim thiab kev tsim khoom raug ntawm cov pwm kuj tseem muaj feem cuam tshuam rau kev ua haujlwm ntawm cov khoom kawg.
5. Kev xaiv cov khoom siv: Cov khoom siv tooj liab zoo thiab cov ntsiab lus alloy yog lub hauv paus rau kev ua kom cov khoom zoo. Thaum lub sij hawm casting txheej txheem, nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv alloy uas tsim nyog thiab cov proportions kom tau raws li cov khoom siv thiab cov kev xav tau ntawm corrosion ntawm castings.
Kev ntsuas kev txhim kho
Nyob rau hauv qhov kev pom ntawm cov teeb meem saum toj no, cov kev ntsuas hauv qab no tuaj yeem raug coj los txhim kho qhov zoo thiab kev ua haujlwm ntawm cam khwb cia tooj liab tooj liab bushings:
1. Txhim kho cov txheej txheem casting: Txo qhov tshwm sim ntawm qhov tsis xws luag los ntawm kev txhim kho cov txheej txheem pouring, kho qhov kub ntawm melting thiab pouring ceev, thiab txhim kho cov khoom ntawm molding xuab zeb.
2. Txhim kho pwm tsim thiab tsim khoom: Txhim kho cov qauv tsim thiab kev tsim cov pwm kom ntseeg tau qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov casting.
3. nruj me ntsis tswj cov khoom sib piv thiab cov ntsiab lus hlau alloy: Xaiv cov khoom siv tooj liab zoo thiab cov ntsiab lus alloy, thiab nruj me ntsis tswj lawv qhov piv thiab cov ntsiab lus kom ntseeg tau tias cov khoom siv kho tshuab thiab corrosion kuj ntawm cov castings.
4. Qhia cov cuab yeej ua haujlwm siab tshaj plaws: xws li centrifugal casting, lub tshuab nqus tsev nqus casting thiab lwm yam kev ntsuas siab heev los txo qhov tsis xws luag thiab txhim kho kev ua haujlwm ntawm castings.
Nyob rau hauv luv luv, casting tin bronze bushings yuav tsum muaj kev txiav txim siab ntawm yam xws li cov khoom siv, casting txheej txheem, pwm tsim thiab tsim los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm castings.
