1, Mvura yegirazi goko

Iyi nzira yave ichigadzirwa muChina kwemakore anoda kusvika makumi mashanu.Mushure mehafu yezana yekuedza kusingaverengeki kwevaanoshanda navo muindasitiri yekukanda mari, kushandiswa uye kutsvagisa kwemvura girazi goko tekinoroji yasvika padanho repamusoro.Kwemakore, simba regirazi remvura goko rakawedzera zvakapetwa kaviri nekuda kwekuvandudzwa kwerefractory yeganda rekumashure uye kufarirwa uye kushandiswa kwehardener nyowani.Mutengo wakaderera, kupfupika kwekugadzira kutenderera, yakanakisa shelling kuita uye yakakwirira permeability zvichiri zvakanakira chero imwe tekinoroji yekupfura.

2. Yakaumbwa shell

Kuenzaniswa negomba regirazi remvura, iyo yepamusoro yemhando yekukanda yakagadziridzwa zvakanyanya, uye hutsinye hwepamusoro, hurema hwepamusoro uye chiyero chekugadzirisa zvakaderedzwa.Inokodzera simbi isina tsvina, simbi inodzivirira kupisa uye imwe yakakwirira alloy simbi.Kutenderera kwekugadzira kupfupi pane kuya kwekushisa kwakadzika wax silica sol shell, yakafanana neiyo yemvura girazi shell.

3、 Silicasol (yakaderera tembiricha wakisi) goko

Nzira yacho inofambirana nemamiriro ezvinhu enyika.Iyo ine hukuru hwekuchinjika uye hukuru kana ichikanda mahombe uye epakati-saizi castings anopfuura 1kg, kunyanya ayo anodarika 5kg.Kana ichienzaniswa negoko rinoumbwa, mhando yegomba yakagadzikana, kunyanya saizi yekukanda yakakwira, hapana sodium silicate, yakanyanya tembiricha kuita kwakanaka, mushure mekubikira pa1000-1200 ℃, ine yakakwira permeability uye inokambaira kuramba, inogona. kuiswa kune dzakatetepa-madziro zvikamu.Led zvikamu, zvidiki uye zvepakati zvikamu zvine chimiro chakaomarara, zvinogonawo kugadzira zvidimbu zvakakura zvine huremu hwe50-100kg, senge pombi yemvura, impeller, etc. Goko rekutungamira, pombi muviri, bhora vharafu muviri, vharafu ndiro, nezvimwe. akakomberedzwa nemadziro madiki uye epakati-kati kana zvikamu zvakakura, ganda reforogo kana kusimudza goko rinogona kudururwa zvakananga pamberi pechoto, uye goho repamusoro rinogona kuwanikwa.

4, Silicasol goko (yepakati tembiricha wakisi)

Iyi ndiyo nzira yekugadzira yakajairika yekukandira kwakaringana munyika.Iine casting quality uye kugadzirisa mwero we.Iyo inonyanya kukodzera kune madiki uye epakati-saizi castings (2-1000g) ine yakakwirira pamusoro roughness uye dimensional kunyatsoita.Nekudaro, nekuda kwekushomeka kwemidziyo uye mutengo, haiwanzo kushandiswa kune makuru uye epakati zvikamu (5-100kg)
