Dab tsi yog qhov kev soj ntsuam zoo ntawm silicon hlau 553?
Cov qauv ntsuas zoo ntawm cov xim hlau silicon 553 feem ntau npog nws cov tshuaj muaj pes tsawg leeg, lub cev thiab lwm yam khoom muaj feem xyuam. Raws li cov qauv no, nws muaj peev xwm ua kom ntseeg tau tias silicon hlau 553 ua tau raws li qhov yuav tsum tau muaj ntawm kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam casting. Cov hauv qab no yog cov qauv ntsuas tseem ceeb rau silicon hlau 553:
1. Tshuaj muaj pes tsawg leeg yuav tsum(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Lub ntsiab tseem ceeb ntawm cov hlau silicon 553 yog silicon, thiab nws cov ntsiab lus silicon yuav tsum tau tswj ntawm 55% thiab 57%. Cov ntsiab lus ntawm lwm cov ntsiab lus alloying yuav tsum ua raws li qee qhov tshwj xeeb kom ntseeg tau tias lawv cov kev ua tau zoo thiab kev ua haujlwm ruaj khov. Cov ntsiab lus muaj xws li hlau, txhuas, calcium, manganese, titanium, carbon, sulfur, phosphorus, thiab lwm yam. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Cov ntsiab lus ntawm cov khoom no cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov hlau silicon, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem casting, siab dhau ib co ntsiab yuav cuam tshuam qhov zoo ntawm casting.
2. Kev ua tau zoo ntawm lub cev(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Lub cev lub cev ntawm cov hlau silicon, nrog rau nws cov hardness, particle loj thiab melting point, kuj yog ib qho tseem ceeb qhia rau kev ntsuam xyuas nws zoo. Hlau silicon yuav tsum muaj ntau dua purity thiab qis impurities, thiab yuav tsum yog grey los yog silver-grey nyob rau hauv chav tsev kub, thiab cov hais feem ntau yog blocky, granular los yog granular. Nws cov ntsiab lus melting feem ntau yog nyob ib ncig ntawm 1410 degree, muaj zog antioxidant muaj peev xwm thiab tsis tshua muaj reactivity, uas ua rau nws dav siv nyob rau hauv ib puag ncig kub.
3. Granularity yuav tsum(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Qhov loj me me ntawm cov xim hlau silicon 553 kuj yog ib qho tseem ceeb ntawm cov qauv zoo. Feem ntau, qhov luaj li cas ntawm cov hlau silicon yog 0-10 hli, qhov loj me me yog ntxhib heev tuaj yeem cuam tshuam rau cov txheej txheem tom ntej, qhov loj me me dhau lawm yuav ua rau cov plua plav thiab tsis tiav thiab lwm yam teeb meem. Yog li ntawd, cov khoom ntawm cov hlau silicon yuav tsum tau ua kom zoo ib yam thiab ua tau raws li cov kev xav tau ntawm kev lag luam.
4. Tswj cov ntsiab lus impurity(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Ntxiv rau silicon, nws yog xim hlau silicon inevitably muaj qee qhov impurities, feem ntau suav nrog hlau, txhuas, calcium, titanium, manganese, carbon, sulfur, phosphorus, thiab lwm yam. Cov ntsiab lus ntawm impurities muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov hlau silicon, cov ntsiab lus siab impurity yuav txo tau cov nyhuv deoxidation thiab cov nyhuv alloying ntawm cov hlau silicon, thiab tseem cuam tshuam rau nws cov molding kev ua tau zoo hauv cov txheej txheem casting. Yog li ntawd, cov ntsiab lus impurity ntawm nws yog xim hlau silicon yuav tsum nruj me ntsis tswj xyuas kom meej tias nws haum rau cov casting thiab metallurgical industries.
5. Cov txheej txheem xeem(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Kev tshawb pom zoo ntawm silicon hlau 553 feem ntau yog siv cov qauv tshuaj ntsuam xyuas cov txheej txheem, xws li kev tsom xam spectral, X-ray fluorescence spectroscopy (XRF), tshuaj titration, thiab lwm yam, los txiav txim seb lub hauv paus muaj pes tsawg leeg ntawm silicon hlau. Tsis tas li ntawd, kev txiav txim siab ntawm qhov loj me feem ntau yog siv txoj kev tshuaj ntsuam xyuas, los ntawm kev tshuaj ntsuam los txiav txim qhov kev faib tawm ntawm qhov sib txawv ntawm qhov ntau thiab tsawg.
6. Ntim thiab khaws cia(Dab tsi yog tus qauv tshuaj xyuas zoo ntawm silicon hlau 553?)
Silicon hlau 553 feem ntau yog muab rau hauv hnab lossis hauv ntau. Txhawm rau kom ntseeg tau tias nws zoo, nws yog ib qho tsim nyog los tiv thaiv kev ya raws, corrosion, thiab kev sib cuag nrog huab cua puag thaum thauj thiab khaws cia. Qhov chaw cia khoom yuav tsum tau qhuav kom tsis txhob ya raws ua rau oxidation los yog caking ntawm cov hlau silicon nto.
Hauv cov ntsiab lus, cov qauv ntsuas zoo ntawm cov hlau silicon 553 feem ntau suav nrog nws cov tshuaj muaj pes tsawg leeg, lub cev muaj zog, qhov loj me, cov ntsiab lus tsis huv thiab lwm yam. Ua kom tau raws li cov qauv no tuaj yeem ua kom muaj txiaj ntsig zoo ntawm cov hlau silicon hauv cov txheej txheem casting thiab metallurgical.
