Molten iron pretreatment device for steel production

The utility model relates to the technical field of steel manufacturing, in particular to a molten iron pretreatment device for steel production, which is characterized in that a base is mounted at the lower end of a box body, a transmission box is mounted at the upper end of the box body, an agent box is mounted above the transmission box, and a first motor is mounted on one side in the transmission box; and a first bevel gear is mounted at the output end of the first motor. The device is simple in structure, when the device is used, the first bevel gear is driven by the first motor to rotate, then the second bevel gear drives the stirring roller to rotate, and the rotating roller drives the spiral conveyor to rotate under the driving of the second motor, so that molten iron enters the inner cavity from the first leakage hole and leaks out from the second leakage hole; and under the action of the stirring fan, the molten iron and the powder can be uniformly mixed, the pretreatment progress of the molten iron
