Kev soj ntsuam ntawm cov txheej txheem kev tsim khoom ductile casting

Nodular casting txheej txheem:

(1) Cov kev cai nruj rau cov tshuaj muaj pes tsawg leeg, cov ntsiab lus carbon silicon ntawm cov kua hlau qub yog siab dua li cov hlau cam khwb cia hlau, thiab cov ntsiab lus ntawm manganese, phosphorus thiab sulfur hauv cov hlau cam khwb cia yog txo.

(2) Qhov kub ntawm cov kua hlau yog siab dua li ntawm grey casting, thiab poob ntawm cov kua hlau kub thaum lub sij hawm spheroidization thiab inoculation yog compensated

(3) spheroidizing kev kho mob, uas yog, ntxiv spheroidizing tus neeg sawv cev rau cov kua hlau

(4) Ua kev kho incubation

(5) Cov dej ntws ntawm cov yeeb nkab yog qhov tsis zoo, qhov shrinkage loj, yog li qhov xav tau rau qhov kub thiab txias ntau dua thiab qhov loj dua qhov loj, qhov kev thov ntawm riser, txias hlau, siv cov txheej txheem sib txuas ua ke.

(6) Kev kho cua sov

Ductile castings li bearings yuav tsum tau hardness ntau dua, feem ntau cam khwb cia hlau quenching thiab tsis kub tempering kho. Cov txheej txheem yog: txhua yam ntawm castings yog rhuab mus rau ib tug kub ntawm 860-900 degree C, thiab cov thawj matrix yog tag nrho cov austenitized thiab ces txias nyob rau hauv roj los yog molten ntsev kom tiav quenching, thiab ces rhuab thiab tempered ntawm {{1 }} degree C.

Tus thawj matrix hloov mus rau hauv tempered martensite thiab residual austenite qauv, thiab cov duab ntawm tus kheej kheej kheej graphite tseem tsis hloov.

Cov kev kho castings muaj siab hardness thiab toughness, khaws cov lubrication zog ntawm graphite, thiab txhim kho cov hnav tsis kam.

Kev saib xyuas yuav tsum tau them rau cov khoom siv hlau castings

Cov qauv ntawm cov ductile casting system yog yooj yim. Feem ntau 1520 degree ~ 1600 degree C, vim tias qhov kub thiab txias yog siab, lub superheat ntawm molten steel yog loj, lub sij hawm sib txuas ua kua yog ntev, thiab fluidity tuaj yeem txhim kho. Tab sis qhov kub siab dhau lawm yuav ua rau cov nplej ntxhib, kub tawg, porosity thiab xuab zeb thiab lwm yam tsis xws luag. Yog li ntawd, feem ntau me me, nyias phab ntsa thiab complex zoo ductile casting, lub pouring kub yog hais txog lub melting point kub ntawm steel +150 degree ; Qhov ntsuas kub ntawm cov pob tawb tuab tuab yog li 100 degree siab dua nws qhov melting point. Txhawm rau tiv thaiv qhov tsis xws luag xws li tsis txaus, kev sib cais txias, qhov shrinkage thiab porosity, cov kab nrib pleb thiab xuab zeb, nws yog ib qho tsim nyog yuav tsum tau siv cov cuab yeej cuab tam ntau dua li cov cam khwb cia hlau: 1, vim tias qhov shrinkage ntawm cov ductile castings zoo heev hla cov cam khwb cia hlau. kev txiav txim kom tsis txhob ductile castings los ntawm shrinkage qhov thiab porosity tsis xws luag, cov txheej txheem casting feem ntau txais kev ntsuas xws li spouts thiab txias hlau thiab nyiaj pab kom ua tau raws li cov solidification.2, vim cov dej ntws ntawm cov hlau tsis zoo.
