Kodi kupanga konkire refractory ndi manja awo?

Yomanga maofesi a zolinga zosiyana zambiri amafuna kugwiritsa ntchito zinthu zosagwira moto. Iwo akhoza kugwiritsidwa ntchito kuteteza anthu ndi nyumba. Monga mmodzi wa zomangira mutuluka refractory konkire. Ena mwa mitundu yake angathe likufa kukhudzana ndi kutentha kwa 1000 ° C, ndi mawonekedwe ndi katundu wofunika ikutsatiridwa.

katundu Ofunika

Pakati mbali yaikulu ya konkire ziyenera utoto

• mkulu refractoriness;
• kumatheka katundu ntchito;
• mphamvu;
• palibe ayenera kugwiritsa ntchito mtengo yowotcha njira kupanga lapansi.

Pakali pano, refractory konkire akhoza wachinsinsi ndi kulemera. Khalani kapena kuti tinganene mwa mitundu zotsatirazi zakuthupi:

• aakulu kwambiri;
• zosavuta;
• thumba;
• lolemera.

Motero, zinthu zikhoza kuwapeza amene angachichite structural kapena zokutira zitsulo ntchito imene zimadalira zikuchokera pophika.

mbali opanga

Ngati aganiza kuti refractory konkire, ayenera tione kapangidwe kake. Zofunika anaphedwa pa maziko a zigawo zikuluzikulu ndi zina zina, lomwe ndi:

• Fireclay mchenga;
• magnesite;
• Osiyana mitundu ya makhalidwe ;
• aluminous simenti.

Mwa zina ndi kukhala bata kuonetsetsa mphero pansi ndi mchere, amene amapereka mphamvu zakuthupi. Mwa zina:

• pumice;
• finely kuuluka chromite miyala;
• kuphulika ng'anjo slag.

zigawo zikuluzikulu zimenezi anawonjezera kuonjezera osalimba a osati chotsirizidwa, komanso zikuchokera youma. Nthawi zina, placeholders kupanga wobadwa wakumvera mbewu, koma nthawi zina akhoza kugwiritsidwa ntchito miyala refractory ndi kumenyana zipolopolo njerwa refractory. Pakuti sukulu zosiyanasiyana konkire anawonjezera aggregates a magulu osiyana. Ngati ndi nkhani ya coarse, zinthu zikhoza kukhala awiri mu osiyanasiyana mamilimita 5 mpaka 25. Pankhani ndalama, ndi malire a 0,15 ndi 5 mm. Mwa zakudya zimenezi ayenera utoto

• magnesite njerwa;
• fireclay njerwa;
• nkhondo njerwa wamba;
• aluminous slag;
• diabase;
• basalt;
• zatha kuphulika ng'anjo slag.

Ambiri mwa ogula ndi yowona refractory, amene amapangidwa pogwiritsa ntchito moto dongo, chifukwa ikukwaniritsa zosowa onse yomanga. The aluminophosphate zosakaniza ndi galasi kuchita madzi monga mgwirizano ndi. Portland, Magnesite ndi kupanga aluminous , ndi kutumikira monga binders zigawo zikuluzikulu. Ngati zosakaniza akuwonjezeka galasi madzi, kusintha ntchito. Izi ndi zoona makamaka ngati konkire Kusakaniza ntchito kupanga pulasitala wosanjikiza.

Malangizo kwambiri pa luso

Refractory konkire, zikuchokera amene akambidwa mu nkhaniyi, mwina mtundu winawake. Mtundu uliwonse amafuna Kuwonjezera plasticizer ake, ufa magnesite ndi ferrochromium slag. Ngati muli ndi cholinga kukonzekera zanthawi konkire, muyenera ntchito kukodzedwa chuma cha mtundu:

• vermiculite;
• kukodzedwa dongo;
• perlite.

Ngati mwaganiza choti ulimi wa osakaniza kwa katswiri, chiŵerengero cha zigawo zikuluzikulu, adzatola okha, malinga ndi ntchito yanu. The zikuchokera amasankhidwa molingana ndi ntchito kutentha ndi utumiki zinthu.

Komanso, zikuchokera mtundu wa filler

Ngati mwaganiza kuti yowona refractory ndi manja awo, ndiye kuti fillers osiyana angagwiritsidwe ntchito, akuti:

• dinas;
• corundum;
• khwatsi;
• wokonzeka kasakaniza.

Poganizira zikuchokera konkire, kuunikila mtundu. Mwachitsanzo, ASBG ndi youma refractory zotayidwa munali osakaniza, amene ntchito akakhala ndi nonferrous zitsulo ndi mphamvu matenthedwe. Mkulu-aluminiyamu simenti ndi katundu refractory chidule VGBS ndi cholinga kulenga akalowa monolithic wa akuponya ladles, malinga ndi pansi chipangizo.

zikuchokera otere ntchito pa kutentha kwa 1800 ° C. Kulimbikitsa youma chisakanizo cha mkulu-Saba anasankha mwa akalatawo. Iwo anafuna mayunitsi ikukhudzana mauvuni ndi zida za wosanjikiza ikuthandizira. Ndinakumana ndi kutentha angafikire mlingo wa 750 ° C.

Screed

Kuyanika konkire refractory akhoza kuchitika pambuyo akamaliza oipa sitepe. Pankhaniyi mpweya ntchito ndi yozungulira kutentha sayenera poyerekeza +10 ° C. Pamaso pa koyamba Kutentha konkire asungidwe kwa tsiku kapena kuposa kukwaniritsa khazikika. kuyanika ntchito zimathandiza kuchepetsa kuchuluka kwa madzi mfulu konkire, zimene zimachititsa mankhwala anachita pakati pa mlengalenga ndi padziko mwake.

Pambuyo kuchiritsa zapamadzi, amasiyako china mu chikhalidwe chinyezi popanda kuyanika. Pambuyo akuchiritsa uli wathunthu ayenera kukhala wouma akalowa. Ngati zimenezi sizingatheke, konkire, amasiyako china mu malo chatsekedwa chinyezi. Nkofunika kuonetsetsa mpweya wabwino kapena kusiya zapamadzi m'dera bwino mpweya wokwanira. Ngati inu mukudabwa momwe kuti refractory konkire, iwo ayenera bwino mbali ngakhale kuphika chifukwa ntchito. Mwachitsanzo, kuyanika sitepe zingatenge malo ntchito zimakupiza abwino kapena blower, amene adzakupatsani mpweya wotentha.

Features chiwiya chako chokandiramo ufa

Musanapite yowona refractory ndi manja awo, zikuchokera njira ayenera mosamala kwambiri osankhidwa. Zimenezi zinanenedwa pamwamba. Koma makhalidwe a kusanganikirana, ndiye izo tikulimbikitsidwa kugwiritsa ntchito nkhafi ndikupita. Ndi bwino kuti kutentha chimateteza konkire, koma njira zothetsera olimba ndi pa zonse zofunikira, chifukwa amalola kusakaniza uniformly ndi molondola chuma ndi Kuwonjezera wa madzi zochepa. Pankhani chosakanizira simenti, ndiye zotsatira zake zimakhala zovuta kukwaniritsa.

kuimilidwa Izi zikugwirizana komanso chifukwa chakuti, kwa wandiweyani konkire chinyezi wokhutira akhoza kukhala wotsutsa. Ndipotu, zipangizo ananena mphamvu pazipita chofunika, pamodzi ndi osalimba mulingo woyenera. Ndi chikhalidwe chawo, chimateteza mwala ndi lililonse limatisokoneza kuposa wandiweyani, choncho n'kofunika kuti n'kuukanda ndi kuchuluka ofunikira madzi. muyeso wake zingachititse kuchepa mphamvu ndi osalimba, koma kupanda adzachititsa kuchepa zokolola.

Anapangira konkire refractory

Kukonzekera konkire refractory iyenera kuchitikira kugwilizana ndi kufanana ena. Ngati ntchito mfundo anakonza chilili moto, ndiye pambuyo kulimbitsa njira athe kupirira kutentha mu zosiyanasiyana 1200 ° C. Kuyambira osakaniza akhoza kukhala moto ndi firebox. Pakuti ntchito kukhala ndi mbali simenti 1 M-400, 2 mbali mchenga njerwa refractory, mbali yomweyo ya nyenyeswa nkhondo njerwa, ndi 0,33 mbali ya chamotte fumbi zowonjezera.

Ngati mukufuna kumanga malo olimba, ndiye iye pa ntchito Kutentha zida adzakhala mpaka kalekale bwanji ndi lawi lotseguka. Izi zimafuna kuti akonze njira ndi kufanana zotsatirazi: 2.5 mbali ya mwala wosweka, mbali simenti, 0,33 mbali ya chamotte mchenga. Koma chomenyedwa, izo akhale wa khwatsi kapena njerwa zofiira, Kapenanso nthawi zina amagwiritsidwa ntchito mphero pansi njerwa zofiira.

Pomaliza

Katundu wa njira polenga yowona refractory ofanana ndi ntchito ochiritsira simenti slurry kusanganikirana. Ngati kukhuta kuti kuchitidwa mu formwork ndi, anayambitsa ayenera kupita mobwerera. Nthawi zina mankhwala ntchito kupanga mosiyanasiyana kwa plywood.

Pofuna kupewa evaporation wa madzi pa solidification, muchikombole pambuyo kupanga ayenera losindikizidwa. Izi facilitates mosavuta kuchotsa castings. Chophweka njira kusindikiza - polyethylene, koma kuti tikwaniritse zotsatira zabwino, muyenera kugwiritsa ntchito silikoni, amene ali chisanadze afewetsedwa ndi mafuta masamba.
