Ua ntej, Hniav phaj ntawmmineral sizers, ua los ntawm ZGMn13, yog ib pawg ntawm 6 daim, ntaub plaub ntim rau hauv ib lub voj voog, rotating crushing raw khoom. Txawm hais tias qhov kev cuam tshuam tsis loj, tab sis vim tias qhov yuav tsum tau ua ntawm qhov tawg particle loj yog me me thiab tsis sib xws, kev tsim ntawm kev siv ntawm qhov chaw yog ntsia thawv zoo li tus, coj txawv txawv, hnav, yuav tsum muaj ntau dua wool sib dhos raug thiab casting zoo.
Thib ob, qhov tseem ceeb ntawm cov txheej txheem casting:
1, xuab zeb siv kev tsom xam: los ntawm cov duab thiab siab precision sib dhos, nws tuaj yeem pom tau tias siv cov av nplaum zoo tib yam, vim qhov nyuaj ntawm molding thiab tsis tuaj yeem ua kom cov duab ntawm cov hniav nto thiab kev sib dhos raug, yuav tsum siv tus kheej - hardening xuab zeb. Kuv ntu feem ntau siv tus kheej- cov xuab zeb tawv yog quartz xuab zeb ua cov khoom tseem ceeb ntawm CO2sodium silicate xuab zeb, vim hais tias nws yog acid xuab zeb, tshuaj xuab zeb yog ib qho yooj yim los tsim nyob rau hauv siab manganese hlau casting, yuav tsum tau txhuam thicker manganese hlau xim los daws. Peb tuaj yeem pom tias cov ntsia hlau tsis yog tsuas yog nyuaj rau txhuam, tab sis kuj yooj yim ua rau cov txheej txheem sib xyaw hauv cov hniav, kom cov hniav tiav tom qab nchuav tsis puv. Yog li ntawd, peb yuav tsum sim xaiv thiab siab manganese hlau nrog alkaline xuab zeb hom, kom tsis txhob tuab txhuam txheej. Cov xuab zeb no mas muaj chromite xuab zeb thiab magnesium violin xuab zeb. Chromium xuab zeb particle loj yog qhov zoo thiab sib xws, muaj peev xwm tsim muaj peev xwm thiab hluav taws kub, yog li nws yooj yim kom tau txais cov khoom zoo, siab precision castings. Tab sis nws cov nqi kim heev, kev siv ntau yuav ua rau cov nqi tsim khoom yog siab heev. Thiabmineral sizersmagnesium olivine xuab zeb, vim hais tias cov particle roundness tsis zoo, particle loj tsis sib xws, yog li lub peev xwm tsim tsis zoo; Nws fractiousness tseem qis dua chromium xuab zeb (siab dua quartz xuab zeb). Tab sis vim nws tus nqi pheej yig thiab siv dav hauv siab manganese hlau casting. Yog li ntawd, qhov kev sim no feem ntau siv magnesium olivine xuab zeb ua cov khoom tseem ceeb ntawm CO2 sodium silicate xuab zeb. Plaub qhov sib dhos ntawm cov av nkos siv chromium ore ua cov khoom tseem ceeb ntawm CO2 sodium silicate xuab zeb.
2, parting nto: raws li tus qauv, parting nto ntawm daim no tsuas yog xaiv nyob rau hauv lub hauv paus arc nto, tswvyim 1 yog tus hniav ntsej muag, tswvyim 2 yog cov hniav ntsej muag. Cov hniav nce toj tsis yog tsuas yog nyuaj rau sau, thiab vim tias cov xuab zeb nyuaj tsis yooj yim rau prick lub qhov cua, ua rau cov kab noj hniav ntawm cov hniav tsis yooj yim thiab tsis txaus pouring. Txhua yam ua rau cov hniav casting tag nrho tsis zoo. Yog li ntawd, cov hniav yuav tsum raug xaiv kom ntsej muag;
3, riser: raws li tus qauv, qhov riser saum npoo yog qhov nyuaj rau kev sib tsoo roj, ua ke nrog cov hlau manganese siab rau kev muab tshuaj txhuam, kev xaiv sab riser yog qhov tsim nyog dua. Yog li ntawd, ob sab risers tau muab tso rau ntawm ob lub ntsej muag kawg, uas yog qhov zoo rau kev sau thiab roj txiav kev sib tsoo;
4, hom ntoo: nruj raws li qhov yuav tsum tau ua ntawm ntoo hom qhov tseeb. Lwm daim ntawv yog ua kom muaj sia nyob ntawm tus ntsia thawv, tus pin kev taw qhia yuav tsum yog perpendicular rau lub dav hlau parting es tsis yog lub arc nto, kom paub tseeb tias nws tsis cuam tshuam qhov tuag;
5, txheej: siv magnesium olivine cawv txheej, ua tib zoo saib xyuas kom tsis txhob ntsia thawv txheej txheej tsub zuj zuj, ntawm no cov txheej yuav tsum nyias nyias, tsis yooj yim los tswj, kuj tsis tuaj yeem txhuam cov xim.
Thib peb, cov nyhuv ntau lawm: raws li cov txheej txheem saum toj no ntawm cov hniav phaj ntau lawm ntawmmineral sizers, qhov saum npoo yog du, sib dhos dimension precision yog siab, tus hniav ntsia hlau yog meej thiab tag nrho. Tom qab cov neeg siv cov ntaub ntawv tawm tswv yim, kev sib dhos thiab siv tau zoo tshwj xeeb.
Plaub, Kev Paub:
1. C02sodium silicate tus kheej- hardening xuab zeb ntawm magnesium olivine xuab zeb yog heev haum rau casting nrog siab qhov tseeb, du nto thiab ntau dua
Lub kaum ntse ntse, cov qauv zawj me me tsis yooj yim rau txhuam cov txheej txheem siab manganese hlau me me thiab nruab nrab;
2. Wool siab manganese steel qhov chaw ntawm lub qhov tob me me, me me sib sib zog nqus zawj qauv siv chromite xuab zeb CO2sodium silicate tus kheej - hardening xuab zeb, tuaj yeem ua tau zoo dua
Xyuas kom raug casting raug thiab tiv thaiv cov xuab zeb "hlawv";
3. cov qauv taw qhia me me ntawm casting, nyob rau hauv tus kheej- hardening xuab zeb casting, yuav tsum kom deb li deb li sai tau los txais yuav downward tswvyim, los xyuas kom meej cov taw tes qauv
Zoo thiab puv.
