The bottom plate 16 is connected to the top surface of the vehicle body 24, and the top surface of the load-bearing beam 13 bears the molten steel tank body 12 and transmits pressure to the high temperature resistant weighing sensor 20. A vertical side sealing plate 15 is connected to the bottom plate 16 and / or the load-bearing beam 13. The side sealing plate 15 of this embodiment is specifically connected to the load-bearing beam 13 through a first bolt 14 to cover the bottom plate 16 on four sides at the same time. There is a gap between the plate 16 and the high temperature resistant weighing sensor 20, and between the high temperature resistant weighing sensor 20 and the load-bearing beam 13, and the high temperature resistant weighing sensor 20 is connected to the bottom plate 16 by a second bolt 17, and a pad 19 for installation is connected to the top of the high temperature resistant weighing sensor 20, and the load-bearing beam 13 is connected to the pad 19 by a third bolt 18. When in use, the molten steel tank body 12 is carried by the load-bearing beam 13, and the pressure is transmitted to the high temperature resistant weighing sensor 20 through the pad 19, so as to detect the weight of the molten steel tank body 12 in real time, thereby obtaining the data of the steel output of the converter.

At the same time, the car body 24 is also connected to a cylindrical tank limit seat 23, and the lower inner wall of the tank limit seat 23 is adapted to the weighing system 11, and the upper inner wall is adapted to the molten steel tank body 12, ensuring the stability of the molten steel tank body 12 when it is on the weighing system 11 of the car body 24. In some embodiments, a lifting ring 21 is connected to the top of the load-bearing beam 13, which can be used for lifting and transferring the load-bearing beam 13 or the entire weighing system 11. At the same time, the bottom of the molten steel tank body 12 also has a groove adapted to the lifting ring 21.
