Hurukuro pamusoro pekugadzirwa kwemagirazi emarbles

Iyo mbishi yegirazi bhora inonyanya kuraswa girazi uye mbishi zvinhu. Kugadzira magirazi egirazi, kutanga kwezvose, marudzi ese e ores anofanirwa kupwanyiwa, akawedzerwa muupfu, uyezve maererano nekuumbwa kwegirazi, yakagadzirwa musanganiswa zvinhu, uye yakashambidzwa pamwe nemarara girazi muvira regirazi rekunyunguduka, kugadzira. girazi mvura. Girazi remvura rinoyerera nemutangi rekudyisa uye rinoda kunyatsonyungudutswa nekujekeswa. Kujekesa maitiro ndiyo yepamusoro tembiricha nhanho mukuita kwegirazi kunyunguduka (1400-1500 ℃), musimboti wekujekesa ndeyekuvandudza tembiricha uye kuderedza viscosity uye kurongeka kwekujekesa mumiriri, kune rumwe rutivi kuderedza bubble. buoyancy kuramba, kune rumwe rutivi kuwedzera bubble vhoriyamu, iyo bubble kubviswa, uye kucheka kwainobva mabhuru anogona kudzokororwa. Mushure mekujekeswa, girazi remvura rinozoyerera richibuda kubva pakubuda kuti rigadzire stock. Stock tembiricha, girazi remukaka rinowanzo 1150 ~ 1170 ℃, rakajairwa girazi girazi i1200 ~ 1220 ℃. Iyo stock inochekwa mumapellets kanosvika mazana maviri paminiti. Bhora "embryo" rinopinda nemuchute, muparadzi webhora, uye rinofambiswa nendiro yekuparadzira bhora, rokunguruka kuita mafeniro akasiyana, robva rawira mubhora rinogadzira mugero wakaumbwa nemarollers matatu ane nzira imwe chete yekutenderera. Bhora "embryo" rinotenderera paroller uye kudhonzwana kwepamusoro paro kunoitika, zvishoma nezvishoma kuumba bhora regirazi rakatsetseka uye rakatenderedzwa.
Pakupedzisira, mushure mekutonhora uye kusarudzwa, ibhora regirazi ratinoona mazuva ese.

Ese mabhora egirazi anoumbwa nemushini panguva imwe chete. Kune mashoma mabhuru mukati memabhora egirazi, uye kumusoro kunochengeta vanga, zvigunwe zvigunwe uye zviri pachena mapoinzi anogadzirwa panguva yekugadzirwa, asi mabhora akatsetseka uye akatenderera.
