_{Poob casting}

Poob pwm castings yog ib qho yooj yim mus cuag mechanized tsis siv neeg ntau lawm kab, ntau lawm kab yog saj zawg zog, thiab zus tau tej cov alloys sib txawv, sib txawv duab thiab txawv qhov ntau thiab tsawg ntawm castings yuav ua tiav ntawm ib tug ntau lawm kab.

1. Qhov loj thiab cov duab ntawm cov casting yog qhov tseeb, qhov rov ua tau zoo, thiab nws muaj cov yam ntxwv ntawm precision casting.

2. High deg tiav ntawm castings;

3. Cov pwm ploj tshem tawm cov xuab zeb pwm thiab cov tub ntxhais ua ntu, thiab tshem tawm qhov tsis xws luag thiab cov khoom pov tseg uas tshwm sim los ntawm cov tub ntxhais ua thiab txiav cov tub ntxhais.

4. Tsis muaj lub thawv, tsis muaj pwm, ua kom yooj yim rau cov txheej txheem molding, tshem tawm cov kev tsis xws luag thiab pov tseg los ntawm pwm noj thiab kaw lub thawv;

5. Cov pwm ploj tau txais cov qauv xuab zeb qhuav yam tsis muaj binder, noo noo thiab lwm yam additives, uas tshem tawm ntau yam casting defects thiab cov khoom pov tseg los ntawm noo noo, additives thiab binders.

6. Cov pwm uas ploj lawm ua kom yooj yim rau kev kho cov xuab zeb, cov xuab zeb moulding tuaj yeem rov qab siv tau, thiab lub tuam txhab molding xuab zeb npaj thiab cov khib nyiab kho xuab zeb raug tshem tawm.

Xya. Shakeout yog ib qho yooj yim heev, uas zoo heev txo cov hauj lwm thiab kev siv zog ntawm shakeout;

8. Lub casting tsis muaj flash burr, yog li ntawd cov kev tu thiab kev sib tsoo yuav raug txo los ntawm ntau tshaj 50%;

9. tuaj yeem muab tso rau hauv qhov zoo tshaj plaws ntawm qhov tsim nyog zoo ntawm lub rooj vag, tsis muaj kev txwv ntawm cov tsoos yam xws li parting, pwm noj, txo qhov tsis xws luag ntawm castings;

10. Qhov tsis zoo siab casting ntawm cov pwm ploj yog qhov zoo dua rau kev txhaws thiab shrinkage ntawm cov kua hlau, thiab microstructure ntom ntom ntawm cov casting yog txhim kho.

11. Ua ke casting, ib lub thawv ntawm ntau daim, zoo heev txhim kho cov txheej txheem casting yield thiab ntau lawm efficiency;

12. Qhov nyiaj pub rau machining raug txo thiab tus nqi machining raug txo.

Carburizing defect

Ua rau carburization defects

ib. Nyob rau hauv cov txheej txheem casting, tus nqi ntawm cov roj tsim los ntawm decomposition ntawm cov pwm ploj yog ntau dhau thiab ceev ceev, qhov ceev nrooj tsis tuaj yeem ntes nrog, thiab lub tshuab nqus tsev twj tso kua mis tsis txaus, uas yooj yim ua rau kev tawg thiab tawg. ntawm cov cam khwb cia;

b. Lub "flash flow" ntawm cov kua hlau yog ib qho ua rau lub cev tsis muaj zog. Lub thiaj li hu ua "flash flow" ntawm cov kua hlau yog tias nyob rau hauv lub pouring, ib feem ntawm cov kua hlau uas tau ntws mus rau hauv txoj hauj lwm ntawm kev sau cov pwm ploj yog hloov mus rau lwm qhov nyob rau hauv qhov kev txiav txim sab nraud, kom cov thawj hloov txoj hauj lwm. tsis nyob ntawm cov kua hlau lossis hlau txhaws. Qhov teeb meem no feem ntau tshwm sim nyob rau sab saum toj casting, lub casting muaj lub dav hlau loj, ib hom thiab ntau cov duab;

c. Yog hais tias lub buoyancy ntawm cov kua hlau yog loj heev, nws yuav ua rau sab sauv ntawm cov pwm xuab zeb yooj yim deform, uas yuav ua rau lub zos vau; Raws li ib txwm muaj, cov xuab zeb tau txais nyob rau sab saum toj ntawm cov pwm yog me me, thiab qhov tsis zoo siab tsis txaus, uas yuav ua rau cov casting tsis zoo los yog tsis tuaj yeem tsim;

d. Lub refractoriness thiab kub siab lub zog ntawm cov xim tsis txaus, thiab nws yog ib qho yooj yim heev los tsim lub cev qhuav dej ntawm lub ploj pwm casting. Cov pwm uas ploj lawm muaj kev ua haujlwm ntawm buffering hlau filling thiab txias thaum lub sij hawm casting txheej txheem, thiab tuaj yeem ua rau cov hlau ntxuav pwm tsis muaj zog. Thaum cov kua hlau hloov cov pwm qauv thiab ua rau cov kab noj hniav, cov xuab zeb qhuav tsuas yog nyob ntawm kev txhawb nqa ntawm cov xim txheej. Thaum lub zog txheej tsis txaus los yog cov refractoriness tsis txaus, cov pwm hauv zos yuav tawg thiab tawg, tshwj xeeb tshaj yog lub cev qhuav dej saum cov khiav hauv qhov loj yog qhov yooj yim heev tshwm sim.
