Izizathu zokuvuza kweziko lokunyibilikisa induction

Ingozi eqhelekileyo kwiziko lomlilo le-induction melting furnace ivuza kwiziko. Ukuba kukho ingozi, ukuba akukho manyathelo athathwayo, kuya kubangela ukuba ityhubhu yobhedu yekhoyili igqabhuke, kwaye intsimbi etyhidiweyo kunye nesipholisi siya kuqhuma. s isizathu:

1. Imiba yomgangatho wezinto ezisetyenziselwa ukwakhiwa kwesithando somlilo: ngokuqhelekileyo sebenzisa i-quartz acid yesithando somlilo. Umxholo we-silicon yesanti ye-quartz kunye ne-quartz powder kufuneka ibe ngaphezu kwe-99.5%, kunye ne-crystals yeoli, ecacileyo kwaye ingabikho ukungcola. Ngokuqhelekileyo sebenzisa isanti ye-quartz ecocekileyo (umxholo we-silicon 99.85%, ubunzima be-8, ubuninzi be-2.65, i-refractoriness 1850 degrees).

2. Imiba ye-binder esetyenziselwa ukwakhiwa kwesithando somlilo: iindlela zokwakha zesithando somlilo ngokubanzi zisebenzisa i-boric acid njenge-binder. I-asidi ye-boric ineenzuzo zombini kunye nokungonakali: inzuzo kukuba ukudibanisa kukhawuleza kwiqondo lokushisa eliphantsi, ngokuqhelekileyo liqala kwi-600-700 degrees; into engalunganga kukuba ayimelani nobushushu obuphezulu kunye nokhukuliseko. Ngaphantsi kweemeko eziphezulu zokushisa, inxalenye ephantsi yodonga lwesithando somlilo iya kubangela isenzeko ukubilisa , Inani lobushushu elisetyenzisiweyo liyancipha kakhulu. Kunconywa ukusebenzisa i-boric acid njenge-binder, kuba i-boric acid ineempawu zokubambisana kweqondo lokushisa eliphezulu, indawo ephezulu yokunyibilika, ukumelana nobushushu obuphezulu, kunye nokumelana nokukhukuliseka.
