Description

Technical Field

[0001] The utility model belongs to the technical field of steel material processing devices, and in particular relates to a steel material leveling and pre-processing device. Background Art

[0002] The raw steel used to produce steel structure assembly beams will bend to varying degrees and warp at both ends during transportation. The surface of the steel will rust during storage. Therefore, the steel needs to be leveled and derusted by a leveler and pretreatment line process before assembly. The leveler squeezes the steel plate through upper and lower rollers to make the surface of the steel flat. The pretreatment line process uses a surface shot blasting process to remove rust and apply a layer of protective paint to improve the corrosion resistance of the steel and extend the service life of the steel.

[0003] However, the existing steel leveling devices and pretreatment line processes still have certain defects: 1. During the leveling process, the operator usually manually pushes the plate into the leveling machine, which makes the direction of the plate entering the device easily deviate and poses certain safety hazards; 2. Most of the existing steel plate pretreatment production lines do not have an oil removal function, which results in some steel plates that are stained with oil during transportation failing to achieve the pretreatment effect, affecting the quality of shot blasting, rust removal and protective paint spraying; 3. Two sets of equipment are used for steel leveling and pretreatment, and workers need to carry steel back and forth, which consumes manpower and material resources and wastes time.
