The surface smoothness of KBK system girder treated by professional machinery is a polishing method which relies on cutting and plastic deformation of material surface to remove the convex part after polishing and to obtain a smooth surface. Generally, abrasive stone and abrasive fluid are used.
Chemical polishing, chemical polishing is to make KBK system main beam material in the chemical medium surface of the micro-protruding part of the concave part dissolve preferentially, so as to obtain a smooth surface.
The main advantage of this method is that it does not need complicated equipment, can polish the KBK system workpiece with complex shape, can polish many steel plates simultaneously, and has high efficiency. The key problem of chemical polishing is the use of polishing fluid and the material of products. The surface roughness obtained by chemical polishing is generally 10m.
