Buluş, ergitme ocaklarında ergitilen sıvı metallerin temizlenmesi için argon ve hidrojen gazı kullanılarak gerçekleştirilen hidrojen gazı seviyesini ayarlama prosesi ile ilgilidir. Bahsedilen proses,sıvı metalin 740 °C sıcaklıkta ergitme fırınındanalınıp gaz giderme makinesine (1) taşınması, rotorun metal içerisine daldırılması, hacimce % 80 argon ve % 20 azot gaz karışımının metal içerisine verilmesi, cüruf ve oksit toplayıcı madde ilave edilmesi, dalga kıranın (11) metal içerisine girmesi, 5-8 dakika süre ile argon ve azot gaz karışımı kullanılarak sıvı metalin gaz ve oksitlerden arındırılması, gaz giderme işleminden sonra hacimce % 70 argon ve % 30 hidrojen gaz karışımının metale verilerek hidrojen gazı seviyesinin ayarlanması işlem adımlarını içermektedir.The invention relates to a process for adjusting the hydrogen gas level using argon and hydrogen gas to remove melted liquid metals in melting furnaces. Said process is carried out by transferring the liquid metal from the melting furnace at 740 ° C to the degassing machine (1), dipping the rotor into the metal, introducing a mixture of 80% by volume of argon and 20% nitrogen gas into the metal, adding slag and oxide collecting agent, ) the gas and oxides of the liquid metal using a mixture of argon and nitrogen gas for 5-8 minutes, after degassing, adjusting the hydrogen gas level by introducing a mixture of 70% argon and 30% hydrogen gas to the metal.
