Khoom Taw Qhia

Lub tog raj kheej thaiv yog qhov tseem ceeb tshaj plaws ntawm kev tsim kho tshuab - extruder, thiab nws txoj haujlwm yog hloov hydraulic zog rau hauv lub zog txhua yam. Thaum kawg ntawm xyoo 2013, peb lub tuam txhab tau tsim cov tuab loj-section lub tog raj kheej thaiv rau ib lub tuam txhab hauv Guangdong, raws li qhia hauv daim duab 1. Cov khoom siv casting qib yog QT600-3, qhov hnyav yog li ntawm 13500kg, qhov siab tshaj plaws sab nraud qhov loj me yog 1980mm × 1330mm × 1130mm, lub tog raj kheej loj yog Φ840mm × 800mm, thiab lub ntsiab phab ntsa thickness yog 330mm. Tus neeg siv khoom muab tso rau hauv qab no yuav tsum tau ua: ① Kev lees txais ntawm cov cam khwb cia yuav tsum ua raws li cov cai hauv qab no: tensile lub zog Rm Ntau dua lossis sib npaug rau 600MPa, elongation A Ntau dua lossis sib npaug li 3%; ② Hauv qab ntawm lub tog raj kheej lub cev, hauv qab thiab lub tog raj kheej phab ntsa R yuav tsum tsis txhob muaj shrinkage lossis pinholes thiab lwm yam tsis xws luag; ③ Sab hauv phab ntsa ntawm lub tog raj kheej yog ua los ntawm cov khoom sib tsoo, thiab lub hardness yog 200-250HB; ④ Tom qab ua tiav, 25MPa dej ntsuas ntsuas tau ua tiav, uas kav ntev li 10min yam tsis muaj dej los yog tawm hws; ⑤ Kev tshuaj xyuas cov hmoov sib nqus, tsis txhob tso cai rau qhov muaj qhov tsis zoo ntawm cov casting uas cuam tshuam rau lub zog, xws li slag inclusion, sand inclusion, porosity.

Technical txoj cai thiab Performance index

Siv tsim nyog tsim hom txias hlau, tsim nyog pouring system, zoo raw cov ntaub ntawv, tsim nyog tooj liab thiab antimony cov ntsiab lus piv thiab nruj txheej txheem tswj, peb muaj peev xwm tsim tuab loj-section lub tog raj kheej thaiv uas ua tau raws li cov neeg yuav tsum tau.

(1) Kev ua tau zoo ntawm 70mm txheem cast test block: tensile zog Rm: 532-578MPa, yield zog Rp0.2:372-415MPa, elongation tom qab tawg : 12. feem: 65-75%.

(2) Qhov nodulation tus nqi ntawm lub hauv qab thiab sab saum toj lub cev ntawm lub tog raj kheej puag yog ntau tshaj 94% nyob rau hauv metallography, thiab tus naj npawb yog 300 / mm2, qhov txawv me me, thiab hardness txawv kuj me me, qhia tau hais tias cov khoom. uniformity ntawm lub tog raj kheej puag lub cev yog qhov zoo heev, thiab nws tsis yooj yim rau tawg thaum nws raug rau siab loj thaum siv.

(3) Kev ntsuas kev puas tsuaj ntawm lub tog raj kheej lub tog raj kheej: txiav ntawm qhov tawg tsis ua haujlwm R txoj haujlwm, kuaj pom xim, tsis muaj qhov tsis xws luag, tshwj xeeb tshaj yog shrinkage thiab slag suav nrog; Metallographic spheroidization tus nqi ntawm 93%, kom muaj nuj nqis ntawm 300 PCS /mm2; Nyob rau tib lub sijhawm, lub zog tawm los Rp0.2 raug kuaj thiab qhov tshwm sim yog 329-367MPa.

Creativity thiab advanced technology

(1) Txawm hais tias qhov chaw twg yog qhov qauv, qhov spheroidization tus nqi ntawm cov casting yog qhov siab, ncav cuag 90%, thiab tus naj npawb ntawm cov pob graphite kuj tseem siab; Qhov no tsis tsuas yog ua kom qhov ntom ntom ntawm cov tuab thiab loj seem castings, tab sis kuj txo qhov nyiam ntawm shrinkage thiab loosening.

(2) Kev siv qhov tsim nyog ntawm cov hlau txias tsis tuaj yeem txhim kho tus nqi spheroidization thiab nce tus naj npawb ntawm graphite spheres, tab sis kuj tseem txhim kho cov pearlite ntim feem kom ntseeg tau tias muaj zog hardness.

(3) Lub tshuab tsim tsim tsim nyog tuaj yeem ua tsis tau tsuas yog ua kom ceev thiab ruaj khov, tab sis kuj ua kom tsis txhob muaj cov slag nkag mus rau hauv pwm thiab txo cov cim ntawm slag suav nrog qhov tsis xws luag.

(4) Kev siv cov ntaub ntawv zoo, xws li cov purity npua hlau, carburizing tus neeg sawv cev, nodulating tus neeg sawv cev, thiab siv cov txheej txheem hluavtaws hlau melting los muab cov kua hlau zoo rau cov khoom tuab thiab loj ductile. hlau casting.

(5) Qhov tsim nyog tus nqi ntawm w (Cu) thiab w (Sb) kom ntseeg tau tias pearlite ntim feem ntawm cov casting matrix yog 65% ~ 85%, thiaj li yuav xyuas kom meej tias cov tuab thiab loj seem casting muaj cov khoom zoo txhua yam.

Kev loj hlob, Scope ntawm daim ntawv thov thiab kev nyab xeeb ntawm kev siv tshuab

Ntxiv rau qhov kev paub tab, cov cuab yeej siv tau zoo rau cov txheej txheem casting los txhim kho cov khoom zoo. Tom qab kev siv cov neeg siv khoom, nws tau raug pov thawj tias lub neej kev pabcuam tau zoo dua qub los ntawm qhov qub 18-24 hli mus rau ntau tshaj 48 lub hlis.

Daim ntawv thov thiab cov teeb meem uas twb muaj lawm

Los ntawm kev sib xyaw ua ke ntawm cov txheej txheem casting tsim nyog thiab cov txheej txheem melting, qhov tsim ntawm ib qho tuab tuab loj ntu lub tog raj kheej thaiv, tom qab kuaj cov kev ntsuas ntsuas tau ua raws li cov neeg siv khoom xav tau. Rau yav tom ntej zus tau tej cov zoo xws li castings mus sau muaj nuj nqis kev. Nyob rau hauv cov txheej txheem kev sim tas mus li, nws pom tau tias cov roj tawg los yog cov roj tsis tawg tsis ua haujlwm feem ntau tshwm sim ntawm R txoj hauj lwm ntawm lub voj voog arc txuas rau lub tog raj kheej hauv qab thiab lub tog raj kheej phab ntsa, thiab kev pabcuam lub neej ntawm lub tog raj kheej feem ntau yog { {1}} hli, ua rau muaj kev poob nyiaj ntau dua. Tom qab txiav qhov chaw tsis ua hauj lwm (qhov twg phab ntsa thickness ntau dua 85 hli), kev tsom xam metallographic (Daim duab 1) pom tias qhov nodularity tus nqi yog 90%, graphite loj yog qib 5, thiab cov naj npawb ntawm cov pob graphite. yog 100/mm2. Yield zog Rp0.2 yog 285MPa. Kev tsom xam pom tau hais tias txawm hais tias R-txoj hauj lwm graphite pob yog puag ncig, nws yog me me thiab tsis ntom txaus, thiab lub zog tawm ntawm 285MPa tsis tuaj yeem tiv taus lub siab loj tsim thaum lub tog raj kheej ua haujlwm, thiab thaum kawg nws ua tsis tiav vim roj. leakage los yog roj seepage.
