The utility model provides a novel aluminum discharging two-man ladle manhole opening and aims to solve the technical problems that the opening and closing directions of a manhole cover of an existing aluminum discharging two-man ladle manhole opening are mostly fixed, in the refining process of high-precision aluminum, the opening and closing directions of the manhole cover of the aluminum discharging two-man ladle manhole opening may hinder refining of the high-precision aluminum, and practicability is low. According to the novel aluminum discharging two-man ladle manhole opening, a movable part is fixedly arranged on one side of the top end of a second limiting ring, a first spring pin is embedded in the bottom of the movable part, a manhole pipe is sleeved with a positioning ring, the bottom end of the positioning ring is fixedly connected with one side of the top end of a fixing ring, and a plurality of inserting holes are formed in the outer side of the positioning ring in an equal-arc mode; a connectin
