Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-4, the gantry type scrap steel baking device comprises a gantry crane 1, a ladle cover 2 and a ladle 3. Lifting lugs 4 are arranged on the ladle cover 2, and the gantry crane 1 is hung with the lifting lugs 4 through lifting ropes so as to lift the ladle cover 2.

The ladle cover 2 is of a high-temperature-resistant fiber module structure, and the fiber module has the effects of high temperature resistance, heat preservation and heat insulation. The upper end surface of the ladle cover 2 is provided with a reinforcing plate 15, the ladle cover 2 is pressed on the ladle 3 through a dead weight cover, and the lower bottom surface of the ladle cover 2 is provided with 3-5 supporting seats 17 which are uniformly distributed along the circumferential direction of the ladle cover 2. Through setting up support 17, when the be built by contract 2 places subaerial, support 17 plays the supporting role to be built by contract 2, makes be built by contract 2 and ground have certain space, the inspection and the maintenance of be convenient for be built by contract 2. 3-5 supports 17 can ensure the stability of the support. The outer diameter of a virtual circle formed by the three support seats 17 is smaller than the inner diameter of the steel ladle 3, so that the support seats 17 do not influence the covering of the ladle cover 2 and the steel ladle 3. The reinforcing plate 15 is not only favorable for increasing the strength of the ladle cover 2, but also can play a role in fixing the burner 5, and can increase the stability of the lifting lug 4.
