Sargheyni is a former deputy minister of Industries, Mining and Trade.
The appointment comes after the former caretaker of the ministry, Hossein Modarres Khiabani, failed to gain a vote of confidence in the Parliament on Wednesday to become the Industries minister.
President Rouhani had appointed Khiabani as the caretaker of the ministry in mid-May to replace ex-minister Reza Rahmani.
