Casting Technology Ntawm GGG60 Ductile Hlau Castings

Yuav ua li cas kom ntseeg tau tias qhov txuas nrog kev sim ntsuas ntawm QT500-7 ua tau raws li cov qauv hauv lub tebchaws?

Mortar test block ntsuam xyuas tus qauv

Txhawm rau ntsuas qhov ntsuas lub zog ntawm cov tshuaj khib nyiab, cov ntawv xeem ntawm tus qauv kho 28d yuav tsum yeej. Daim ntawv xeem yog ib lub voos xwmfab nrog ib sab ntev ntawm 70.7 mm. 6 daim ntawv xeem yog ib pawg, thiab cov pawg yuav tsum ua raws li cov hauv qab no:

1. Cov mortar test blocks nrog cov qib sib txawv ntawm qhov sib txawv thiab qhov sib xyaw sib xyaw yuav tsum tau npaj nyias nyias, thiab cov qauv kuaj yuav tsum tau random npaj thiab xaiv tsis tau.

2. Rau cov tuam tsev tseem ceeb thiab cov masonry tseem ceeb, 2 pab pawg tau npaj rau txhua txoj haujlwm ua haujlwm. Rau cov vaj tse dav dav thiab theem nrab masonry, ib pawg tuaj yeem npaj rau txhua chav ua haujlwm.

3. Lub arch nplhaib mortar test block yuav tsum tau npaj tib lub sij hawm raws li cov masonry nyob rau hauv tib yam kev mob los xyuas lub zog ntawm txhua theem ntawm kev tsim kho.

Raws li "Code for Design of Masonry Structure" thiab "Code for Masonry Engineering and Txais", lub zog qib ntawm mortar test block yog 70.7mm × 70.7mm × 70.7mm xeem daim, uas yog raug rau 20C ± 3C thiab av noo ntawm 60. feem pua ​​-80 feem pua. Cov lej lej ntawm lub zog compressive ntawm 6 tus qauv tom qab kho rau 28 hnub tau txiav txim siab. Mortar muab faib ua 6 qib: M20, M15, M10, M7.5, M5, thiab M2.5. Qhov sib xyaw mortar test block yuav tsum ua kom tau raws li cov qauv tsim ntawm hom thiab qib zog, thiab ua tau raws li qhov yuav tsum tau muaj ntawm qhov sib xws, tuav dej zoo thiab sib xyaw ua ke. Lub zog qib ntawm mortar test block siv rau cov phab ntsa thiab txhua kab uas raug kev co thiab qhov siab tshaj 6M yuav tsum tsis txhob tsawg dua M2.5. Lub zog ntawm mortar test blocks nyob rau hauv qhov chaw txias heev thiab nyob rau hauv qhov chaw ntub dej hauv qab av yog feem ntau nce los ntawm ib theem.

Post Casting txheej txheem

1. Kev kho cua sov: annealing, carbonization, tempering, quenching, normalizing, nto tempering

2. Cov khoom siv ua haujlwm: CNC, WEDM, tshuab dhos, milling tshuab, drilling tshuab, grinder, thiab lwm yam;

3. Kev kho deg: hmoov txau, chrome plating, painting, sandblasting, npib tsib xee plating, galvanizing, blackening, polishing, bluing, thiab lwm yam.

Pwm thiab tshuaj xyuas Fixtures

1. Pwm kev pab cuam lub neej: feem ntau yog semi-permanent. (tsuas yog ua npuas ncauj ploj)

2. Pwm lub sij hawm xa tuaj: 10-25 hnub, (raws li cov qauv khoom thiab cov khoom loj).

3. Tooling thiab pwm tu: Zhongwei yog lub luag hauj lwm rau precision qhov chaw.

Kev Tswj Xyuas Zoo

1. Kev tswj xyuas zoo ntawm High chromium xuab zeb cam khwb cia hlau: Tus nqi tsis zoo yog tsawg dua 0.1 feem pua ​​.

2. Cov qauv thiab kev sim ua haujlwm yuav raug tshuaj xyuas 100 feem pua ​​​​ntawm kev tsim khoom thiab ua ntej xa khoom, kuaj cov qauv rau cov khoom loj raws li ISDO cov qauv lossis cov neeg siv khoom.

3. Cov khoom siv kuaj: kuaj pom qhov tsis zoo, spectrum analyzer, golden duab analyzer, peb-coordinate ntsuas tshuab, hardness kuaj khoom, tensile kuaj tshuab;

4. Muab kev pab cuam tom qab muag.

5. Qhov zoo tuaj yeem taug qab.

Mortar Test Block Loj

Qhov loj ntawm cov mortar test block feem ntau yog tsau, feem ntau yog lub voos xwmfab nrog ib sab ntev ntawm 70.7mm. Raws li tus qauv txheej txheem, tus nqi compressive zog yog txiav txim los ntawm kev kho rau 28d nyob rau hauv cov xwm txheej ntawm (20 ± 2) degree kub thiab txheeb ze av noo tshaj 90 feem pua. Mortar zog qib.

Daim ntawv thov

Thaum GGG60 Ductile Hlau Castings yog qhov kub thiab txias, lub zog hloov mus rau brittleness, tab sis qhov kub tsis tshua muaj qhov cuam tshuam tus nqi siab dua, thiab nws muaj qee yam tsis kam mus rau qhov kub thiab txias hloov thiab corrosion kuj. Nws yog dav siv nyob rau hauv cov roj twj tso kua mis gears ntawm lub internal combustion engine, nruab nrab kub lub tog raj kheej diaphragms ntawm chav turbines, valve lub cev ntawm hydraulic turbines, bearing bushes ntawm railway dov Tshuag, tsav shafts ntawm lub tshuab hauv paus, thiab lwm yam.
