The present invention relates to a copper billet casting apparatus having a reduction device using gas to remove oxygen included in a molten metal using gas during a process of melting and refining copper scrap collected for recycling. To achieve this, the copper billet casting apparatus having a reduction device using gas includes: a cylindrical smelting furnace (1) wherein a scrap inlet (11) is provided on one side to selectively be opened and closed by a door part (9), a burner to heat an internal space is provided on the other side, and an outlet (15) to discharge molten metal (M) is provided on a wall; a smelting furnace rotation device; a raw material charging part (3); a casting part (5) to produce products such as a billet by supplying the molten metal discharged from the smelting furnace (1) to a mold; and a gas injection part (7) to supply gas such as LPG or LNG into the smelting furnace (1). 본 발명은 재활용을 위해 수거된 동스크랩을 용융하여 정제하는 과정에서 용탕에 함유된 산소를 가스를 이용하여 제거하는, 가스를 이용한 환원장치를 가지는 동빌렛 주조장치에 관한 것이다. 그 구성은; 도어부(9)에 의해 선택적으로 개폐되는 스크랩 투입구(11)가 일측에 마련되고, 내부 공간을 가열하기 위한 버너(13)가 타측에 마련되고, 용탕(M)을 방출하기 위한 출탕구(15)가 벽체에 마련되는 원통 형상의 용해로(1); 상기 용해로 회전장치; 원자재 장입부(3); 상기 용해로(1)에서 출탕된 용탕을 금형에 공급함으로써 빌렛과 같은 제품을 생산하는 주조부(5); 상기 용해로(1) 내부에 액화석유가스 또는 액화천연가스와 같은 가스를 공급하기 위한 가스주입부(7)를 포함하는 것을 특징으로 한다.
