Embodiment 1

[0013] S11. Pressure-weld multiple sets of horizontal bars and multiple sets of vertical bars so that they are distributed in a grid pattern.

[0014] The steel bars arranged horizontally in the steel grating are called horizontal bars, and the steel bars arranged vertically are called vertical bars. Several horizontal bars and vertical bars are arranged in a grid and welded together.

[0015] S12, cutting the redundant part at the end of the horizontal bar and the vertical bar.

[0016] After the horizontal bar and the vertical bar are welded, excess parts will be left at the ends, and the excess parts at the ends of the horizontal bar and the vertical bar will be cut by cutting equipment.

[0017] S13. Grinding the burrs on the surface of the horizontal and vertical strips.

[0018] Since there are some burrs on the horizontal and vertical bars that need to be removed, some grinding tools are used to remove the burrs to facilitate subsequent surface treatment.

Abstract

The invention discloses a steel grating plate molding and surface treatment process. The process comprises the following steps of: performing pressure welding on transverse strips and longitudinal strips to form a grating plate; cutting a redundant part at the end of the grating plate; grinding burrs on the surface of the grating plate; removing impurities from the surface of the grating plate; performing assistant plating treatment on the transverse strips and the longitudinal strips; drying the grating plate, and then galvanizing the grating plate; chemically polishing welding residues on the surface of the grating plate; and washing the grating plate, and then drying. Before a steel grating plate is galvanized, the impurities adhered to the surface of the steel grating plate are maximally removed, the surface of the steel grating plate is passivated, and a subsequent galvanizing layer has maximum adhesive force on the surface of the steel grating plate, so the quality of a coating is improved.

Description

technical field [0001] The invention relates to a steel grating forming and surface treatment process. Background technique [0002] Steel grating is widely used, and its use environment is changeable and harsh, requiring it to have high surface quality, high corrosion resistance, and good formability. Electrogalvanized steel grating can better meet its requirements on material surface quality and corrosion resistance. However, due to technological problems, the existing electrogalvanized steel grating still has deficiencies. Contents of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to propose a steel grating forming and surface treatment process, before the steel grating is galvanized, the impurities attached to the surface of the steel grating are firstly removed to the maximum extent , and passivate the surface of the steel grating, so that the subsequent galvanized layer has the greatest adhesion on t...
