Description

Technical Field

[0001] The utility model belongs to the technical field of converters, and particularly relates to a converter bottom rail installation structure. Background Art

[0002] The track bottom plate installation structure is mainly the basis for ensuring the smooth operation of the vehicle under the furnace. The existing track bottom plate installation structure under the furnace is installed on the foundation embedded plate. The embedded plate is installed at intervals of 600mm-1000mm. The embedded plate is made of δ=20mm steel plate. The embedded plate is welded with Φ18mm and Φ20mm threaded steel during base molding to make it embedded, rooted and fixed to bear force; when the vehicle under the furnace is under load, the load is transferred to the track, bottom plate, embedded plate and foundation through the wheels.

[0003] During smelting, splashing or slag overflow will be generated due to operations such as adding molten iron into the converter or inserting an oxygen lance for oxygen blowing. The splashed material will fall onto the track bottom plate, which can easily cause red slag to remain on the track bottom plate. The uneven distribution of thermal stress will cause the track bottom plate and the embedded plate to deform due to heat, causing their welds to crack, which will directly affect the vehicle running track under the furnace, and then the furnace will be forced to be stopped for maintenance such as replacing the bottom plate, which will seriously restrict the production rhythm and effective operation rate.

The slider assembly 8 is composed of a fixed shaft 81 and a roller 82. The fixed shaft 81 is welded to the top of the driven plate 7, and the roller 82 is rotatably connected to the top of the fixed shaft 81. The roller 82 rolls in the inner cavity of the slide groove 11. Through the setting of the roller 82, when the active plate 6 rotates to drive the slider assembly 8 to slide in the inner cavity of the slide groove 11, the roller 82 will roll in the inner cavity of the slide groove 11, thereby reducing the friction resistance between the slider assembly 8 and the inner cavity of the slide groove 11.
