Ndi njira zotani zopangira ma castables?

Pali zinthu zambiri zomwe zimakhudza magwiridwe antchito a castables, monga kusankha zinthu, kumanga, ndi kukonza. Kufunika kwa zomangamanga kumathandizanso kwambiri popanga ma castables. Mkonzi wotsatira akufotokozerani njira zomangira zomwe zimagwiritsidwa ntchito kwambiri:

A. Kuthira njira yomanga

1. Kuyang’anira: Onani ngati nkhunguyo imathandizidwa bwino, palibe mipata ndi zopatuka, ndipo zinyalala mu nkhungu zimatsukidwa, ngati anangula (misomali yosapanga dzimbiri ya palladium) amawotchedwa mwamphamvu, komanso pamwamba pa nangula. Amakutidwa ndi utoto kapena thumba la pulasitiki kuti asungidwe Mphamvu yowonjezera ikatenthetsa.

2. Kuthira: Thirani zosakaniza zothira mu nkhungu, ikani ndodo yogwedezeka kuti igwedezeke, ndikusuntha ndodo yogwedezeka pa liwiro lofanana, ndikutulutsa pang’onopang’ono.

3. Malo otsanulira ndi aakulu kwambiri, amatha kutsanuliridwa mumagulu ndi magawo, ndipo amatha kuyendetsedwa. Khoma limatsanuliridwa mu zigawo, nthawi iliyonse ili pafupi 900mm, pamwamba pa ng’anjoyo imagawanika ndikutsanuliridwa, ndiyeno imakwezedwa.

4. Kuchiritsa ndi kuwononga: kutentha kwa chilengedwe> 20 ℃, nkhungu imatha kuphwanyidwa pambuyo pa 4H, <20 ℃, nkhungu ikhoza kuthetsedwa pambuyo pochiritsa 6-7H, ngati m’mphepete mwa m’deralo ndi ngodya zawonongeka, zikhoza kukonzedwa. . (Nthawi yeniyeni yowonongeka imadalira momwe malo alili).

B. Njira yomanga yopaka mafuta

1. Choyamba fufuzani ngati anangula (misomali yachitsulo yosapanga dzimbiri ya palladium) imawotchedwa mwamphamvu. Pentani anangula kapena kukulunga m’matumba apulasitiki kuti muteteze mphamvu yokulira mukatenthetsa.

2. Gwiritsani ntchito kupaka pamanja kwa chosakaniza chosakanikirana molunjika pamalo ogwirira ntchito.

3. Malo ogwirira ntchito ayenera kugwiritsidwa ntchito mosalekeza mu zigawo kuchokera pansi mpaka pamwamba. Kutalika kwa wosanjikiza aliyense ndi pafupifupi 900mm, ndipo makulidwe a gawo lililonse ndi pafupifupi 80mm. Kuchulukana kukafika pakukula kofunikira, gwiritsani ntchito chida chopukutira pomangapo.

4. Gwiritsani ntchito mosalekeza pamwamba pa malo omangapo m’magawo, ndi gawo pakati pa zigawo ziwiri zowonjezera, nthawi iliyonse 30-50mm, pamene makulidwe afika pa kukula kofunikira, gwiritsani ntchito chida chopukutira pamwamba pa zomangamanga.

5. Pazitsulo zopangira kutentha kwa mapaipi akuluakulu opingasa, njira yopangira chingwe m’magawo poyamba ndikuyimitsa kugwirizana iyenera kutengedwa. Pamene payipi imangidwa m’zigawo, ikani payipi mopingasa, ikani kagawo kakang’ono kakang’ono, ndipo mutatha kuchiritsa mwachilengedwe kwa 4-8h, tembenuzirani payipi 180 ° ndikuyikanso gawo lina la semicircular, ndipo chitani chithandizo cholumikizana chitolirocho chikatha. cholumikizidwa.

C. Njira yopangira utsi

1. Weld zitsulo palladium misomali kapena zitsulo mauna (kutentha zosagwira zosapanga dzimbiri zitsulo) pa ng’anjo chipolopolo choyamba.

2. Ikani utoto wopopera mu chopopera, gwiritsani ntchito mpweya woponderezedwa (kukakamiza 0.10-0.15MPa) kutumiza kusakaniza ku mphuno, ndikuwonjezera madzi oyenerera kapena cholumikizira mankhwala kuti musakanize ndi zinthuzo, ndikuzipopera ku kumanga pamwamba.

3. The nozzle outouts ayenera kukhala perpendicular kwa yomanga pamwamba, mtunda ndi 1-1.5m, kupopera mbewu mankhwalawa ayenera mosalekeza, ndipo makulidwe a kupopera mbewu mankhwalawa aliyense ayenera kukhala zosakwana 200mm.

4. Ngati kupopera mankhwala kwa malo omangawo kuli wandiweyani kwambiri, kuyenera kupopera mu zigawo, koma ziyenera kuchitidwa pambuyo poti gulu lapitalo lili ndi mphamvu zokwanira. Pambuyo kupopera mbewu mankhwalawa, malo ogwirira ntchito amayenera kusalala ndipo zinthu zomwe zimabwereranso ziyenera kutsukidwa.

Mwachidule, kutsatira mosamalitsa njira zomangira ndi masitepe kumagwira ntchito yofunika kwambiri pakuchita ma refractory castables.
