Casting txheej txheem ntawm High Chromium cam khwb cia hlau

Tshuaj muaj pes tsawg leeg tsim ntawm siab chromium cam khwb cia hlau: (feem ntau hypoeutectic siab chromium cam khwb cia hlau yog siv).

1.Nyob rau hauv cov txheej txheem, tus naj npawb ntawm carbides feem ntau hloov los ntawm kev kho cov ntsiab lus carbon.

2. Rau high-chromium cam khwb cia hlau tsis muaj lwm yam alloying ntsiab, lub siab tshaj plaws txoj kab uas hla uas yuav hardened los ntawm huab cua quenching yog 20 hli. Txhawm rau txhim kho hardenability, cov ntsiab lus alloying yuav tsum tau ntxiv.

3. Manganese drastic txo Ms, uas yuav ua rau siab chromium cam khwb cia hlau kom muaj ntau tuav austenite tom qab quenching. Yog li, nws feem ntau tswj tau qis dua 1.0 feem pua ​​.

4. Qhov txo qis ntawm Ms los ntawm tooj liab yuav ua rau ntau cov austenite khaws cia. Yog li, nws feem ntau tswj tau qis dua 1.5 feem pua.

5. Vim yog tus nqi siab V, feem ntau tsuas yog tsim rau cov castings uas tsis yooj yim rau kev kho cua sov.

6. Qhov nce ntawm Ms hauv silicon yuav txo cov austenite khaws cia thiab txo cov hardenability. Yog li ntawd, feem ntau nws yuav tsum tau tswj.

7. Lub melting kub ntawm high-chromium cam khwb cia hlau induction rauv yog 1480 degree, uas yog txaus thiab tsis tas yuav siab dhau heev lawm.

8. Lub pouring kub ntawm High chromium xuab zeb cam khwb cia hlau yuav tsum tsis txhob yuav siab dhau heev lawm, yog li kom tsis txhob muaj ntau shrinkage thiab nplaum xuab zeb. Qhov ntsuas kub yog 1350-1400 degree rau tuab thiab loj (1380-1420 degree rau qhov dav dav). High pouring kub aggravates lub shrinkage kab noj hniav nyob rau hauv lub riser, thiab yuav ua rau ntom micro-shrinkage thiab coarse grain qauv.

9. Lub shrinkage tus nqi siab chromium cam khwb cia hlau qauv yog 2 feem pua.

10. Lub riser loj ntawm siab chromium cam khwb cia hlau yog tsim raws li carbon steel, thiab lub rooj vag system yog tsim raws li grey cam khwb cia hlau. Lub pouring riser yog txiav los ntawm cov roj txiav txoj kev, uas yog nquag mus rau kub tawg. Yog li ntawd, qhov yooj yim-txiav riser los yog sab riser yog siv rau hauv kev tsim, thiab cov txheej txheem khob yog siv los tshem tawm.

11. Yog vim li cas rau lub neej luv luv ntawm high-chromium cam khwb cia hlau yog tsis yog lub metallographic theem tsis tsim nyog, tab sis hais tias muaj casting defects xws li shrinkage kab noj hniav, pores, thiab inclusions nyob rau hauv lub casting, yog li cov txheej txheem casting yuav tsum tau them. txaus siab.

12. High chromium cam khwb cia hlau yog yooj yim tawg. Hauv kev tsim cov txheej txheem casting, kev saib xyuas yuav tsum tsis txhob thaiv qhov shrinkage ntawm casting kom tsis txhob tawg.

13. High chromium cam khwb cia hlau castings yuav tsum tau txias tag rau hauv pwm, thiab ces unpacked. Thaum ntxov unpacking thiab siab unpacking kub yog lub ntsiab yog vim li cas rau cracking ntawm castings.

14. Thaum high-chromium cam khwb cia hlau yog cam khwb cia hlau pwm, lub pouring kub yuav tsum tau khaws cia saum toj no 150 degree los tiv thaiv lub casting los ntawm txias sai heev thiab tawg.

15. High-chromium cam khwb cia hlau txais high-temperature cua quenching thiab nruab nrab-tsawg kub tempering kub kho kom tau ib tug high-hardness martensite matrix.

16. Cov qauv as-cast matrix ntawm high-chromium cam khwb cia hlau ua ntej kev kho cua sov yog nyob ntawm qhov ua kom txias txias. Thaum qhov txias txias yog siab, nws feem ntau yog austenite matrix: raws li qhov txias txias txo, sib tov ntawm martensite, pearlite thiab austenite maj mam pib los nag. Qhov txias txias yog ntxiv txo, thiab cov qauv pearlite matrix tuaj yeem tau txais.

17. Qhov zoo tshaj plaws quenching kub ntawm high-chromium cam khwb cia hlau yog feem ntau xaiv raws li cov ntsiab lus chromium thiab phab ntsa thickness ntawm cov khoom. Qhov siab dua qhov quenching kub, qhov siab dua qhov hardenability, tab sis ntau dua qhov khaws cia austenite uas yuav raug tsim tom qab quenching. Lub quenching kub ntawm Cr15 siab chromium cam khwb cia hlau yog 940-970 degree, thiab quenching kub ntawm Cr20 siab chromium cam khwb cia hlau yog 960-1010 degree . Lub sijhawm tuav yog xaiv raws li phab ntsa thickness. Feem ntau 2-4h, phab ntsa thickness 4-6h.

18. Lub high-chromium cam khwb cia hlau tom qab cua quenching muaj loj sab hauv, thiab tempering kub kho yuav tsum tau nqa tawm sai li sai tau.

19. Rau ib co high-chromium cam khwb cia hlau castings nrog complex cov duab thiab zoo disparities nyob rau hauv phab ntsa thickness, cov cua kub kub (tsawg tshaj los yog sib npaug zos rau 50 degree / h) yuav tsum nruj me ntsis tswj kom tsis txhob tawg ntawm cov castings. Qee lub sij hawm nws muaj kev nyab xeeb dua los siv cov cua sov (nyob ntawm 200 degree , 400 degree , thiab 600 degree rau 2-3 teev), thiab qhov kub nce siab tshaj 700 degree tuaj yeem tsim nyog nrawm. Tab sis tsis ntau tshaj 150 degree / h.

20. Lub sij hawm tuav yuav tsum tau muab xam raws li cov yam ntxwv xws li phab ntsa thickness ntawm lub casting, tus nqi ntawm lub cub tawg ntsia, lub xeev thiab cov cua kub npaum li cas, thiaj li tsis txhob quenching ntawm ib co castings los yog cov tub ntxhais ntawm cov casting. vim lub sij hawm tuav tsis txaus.

21. High chromium cam khwb cia hlau yuav tsum tau deoxidized thaum nws tawm ntawm lub cub tawg. Feem ntau, 0.5 feem pua ​​​​ferromanganese yog ntxiv rau lub cub tawg rau pre-deoxidation, 0.25 feem pua ​​​​ntawm ferrosilicon yog ntxiv rau lub cub tawg rau qhov pib deoxidation, thiab 0.05 feem pua ​​ntawm aluminium ntxiv rau lub hnab rau qhov kawg deoxidation.

22. Qhov kub ntawm high-chromium cam khwb cia hlau yog tswj ntawm 1450 degree thaum lub sij hawm smelting txheej txheem, thiab qhov kawg ceev kub nce yog tswj ntawm 1480 degree rau deoxidation.
