Technical method for optimizing weighing box girder of molten iron scale

The invention discloses a technical method for optimizing a weighing box girder of a molten iron scale, relates to the technical field of weighing box girders of molten iron scales, and aims to solve the technical problems that a box girder in the prior art is unreasonable in mechanical structure design, a rib plate is not right above a weighing sensor of the scale, and the stress position of an upper pressing plate of the weighing sensor is too thin and is easy to deform. The method comprises the following steps that 1, the impact resistance of the weighing box girder is improved; 2, optimizing a lap welding mode, and reducing stress at a welding path: welding a side steel plate at a position 10mm away from the inner side of the middle steel plate; and 3, round steel is additionally welded in the weighing box girder. According to the method, by increasing the thickness of the middle steel plate and the upper pressing plate, cracking damage is not prone to occurring in the long-term high-load state, the heigh
