Sistem Selimut Logam Cair
Solusi eksklusif untuk meningkatkan operasi pengecoran Anda
Teknologi blanketing logam cair Air Products dapat membantu operator pengecoran besi dan non-besi meningkatkan hasil dan mengurangi biaya pengoperasian secara keseluruhan. Teknologi kami yang telah dipatenkan menggantikan oksigen atmosfer dan uap air dengan atmosfer argon atau nitrogen yang kering dan inert sehingga Anda dapat menyelimuti permukaan lelehan untuk mencegah oksidasi logam dan pengambilan gas. Dengan mengurangi oksidasi logam, teknologi eksklusif kami dapat membantu Anda mengurangi biaya paduan dan meningkatkan kebersihan dan kualitas lelehan - sehingga mengurangi pengerjaan ulang dan skrap. Dengan teknologi vortex sprayer dan swirl cone kami yang telah dipatenkan, Anda mungkin dapat menggunakan gas 50% lebih sedikit daripada teknik pelapisan logam cair konvensional dalam tungku induksi dan crucible Anda. Solusi optimal untuk proses Anda bergantung pada banyak faktor, seperti parameter pengoperasian tungku Anda, sasaran kualitas, dan kondisi pasar saat ini.

"How can I reduce my gas consumption for molten metal blanketing?"
By reducing the oxygen content above the induction furnace, inert gases—typically argon—have proven benefits for blanketing molten metal, including higher yields, lower alloy fading, decreased nonmetallic inclusions, reduced casting porosity, lower casting rework and rejects, and increased refractory lifetime. However, inert gas costs can impact your bottom line. Air Products’ patented swirl cone technology can deliver these benefits while using up to 50% less argon. In side-by-side testing, our technology reduced the oxygen level above the furnace to less than 2%, with little or no interference to the melting operation. In addition, the technology’s design enables it to remain in place during charging and pouring.
