The invention discloses a molten iron transport system, which comprises a first transport path of molten iron in a blast furnace, a second transport path of molten iron between adjacent blast furnaces, and a third transport path for transporting molten iron to a steel-making plant, wherein the first transport path is linearly arranged between the blast furnace and the second transport path ; the second transport path is linearly arranged between two adjacent blast furnaces; the third transport path is linearly arranged between the second transport path and the steel-making shop; a first transport vehicle is arranged at the transition position of the first transport path and the second transport path; a second transport vehicle is arranged at the transition position of the second transportpath and the third transport path; a desulfurizing station is also arranged at the transition position of the second transport path and the third transport path ; a first ground molten iron tank car,a second ground molten iron tank car and a third ground molten iron tank car are respectively arranged on the first transport path, the second transport path and the transport path third. The molten iron transport system has high transport continuity, and can maximally shorten the transport cycle and eliminate the influence of centrifugal force on the production safety in the transport process, thus improving the transport speed and reducing temperature drop of the molten iron.

The invention discloses a molten iron transportation online molten iron tank heat preservation device. Two ladle covering and uncovering mechanisms are arranged on molten iron transport carts (5) and symmetrically distributed at the two sides of a molten iron tank (4) with the axis of the molten iron tank (4) serving as the center. By the adoption of the technical scheme, the molten iron tank is transported in a covered mode in the whole molten iron transport cart operation process, the molten iron tank is covered for heat preservation, and therefore energy loss caused by molten iron temperature drop is reduced; a four-bar mechanism is adopted, covering and uncovering operation conducted on a molten iron pouring station with narrow space is achieved; normal operation of the two carts is not affected; each molten iron tank heat preservation device is only provided with one power execution device and a point of action is near the center of symmetry of the mechanisms, so that overall stable operation of covering and uncovering operation of the mechanisms is guaranteed; the structure is compact, operation is simple, use is convenient, and the device is safe, reliable and long in service life.

The invention relates to a tank body tilting safety control device of an iron mixing vehicle, which belongs to blast furnace iron making and relates to a blast furnace molten iron transport device. The tank body tilting safety control device comprises a vehicle body, a tank body, a tilting mechanism, a high speed receptacle and a junction box, wherein the tank body, the tilting mechanism, the high speed receptacle and the junction box are arranged on the vehicle body, the tilting mechanism is connected with a large gear of the tank body through a chain, and an electrical control box is arranged on the ground and electrically connected with the high speed receptacle. The tank body tilting safety control device is characterized in that a tilting two-way contact is arranged on the center line of the tank body, a zero position contact is arranged under the center line, the tilting two-way contact and the zero position contact respectively correspond to a tilting travel switch and a zero position travel switch which are arranged on a platform, and the tilting travel switch and the zero position travel switch are electrically connected with the junction box. The tank body tilting safety control device has the advantages of novel concept, simple structure, easiness in operation and low manufacturing cost. The position of the tilting travel switch can be adjusted so as to adapt to different tilting angles of the tank body, the tilting process is safe and reliable, an accident that molten iron falls on the ground because the tank body is tilted and out of control due to mechanical, electrical and operational causes is effectively avoided, waste of the molten iron is reduced, the cost for maintenance and spare parts is reduced, the online operation turnover rate of the iron mixing vehicle is increased, and smooth production is guaranteed.
