Pressure welding steel grating types: surface shape into the tooth by bonding steel lattice panels, flat type, type I and composite bonding steel grating. Steel grating surface treatment according to the situation can be divided into pressure welding galvanized steel grating, and the original painting pressure bonding steel grating. Pressure welding steel grating flat steel, rail specifications: 1, pressure welding steel grating steel: the material is Q235A Anping galvanized or stainless steel grating, a common plane type, tooth type and section I slip type. Common specifications 20 * 5,25 * 5,25 * 3,32 * 5,32 * 5,40 * 5,40 * 3,50 * 5,65 * 5,75 * 6,100 * 8,100 * 10 and so on. 2, pressure welding steel grating crossbar: Material for Q235A or 304 stainless steel round bar, twisted steel, square steel or six angles. Twisted square steel plate garden by the side of the mold by drawing and twisted from the standard hot-dip galvanized steel grating, its common specifications are 5 * 5,6 * 6,8 * 8mm and so on. Galvanized grating pre-cleaning process galvanized top grill plate by spray cleaning tank cleaning device, the 1st brushing machines, electrolytic cleaning tank, the 2nd brushing machine, fat bowl of hot water, but air dryer and cleaning segment circulatory system, the exhaust gas purifying means composed of the discharge system. Its advantages are as follows: (1) before entering the annealing furnace strip pre-cleaned in the cleaning section processing. Not only can thoroughly remove dirt concentrated deficit and the strip surface. But also to remove the residues within the pit strip galvanized steel grating, fully clean strip surface. (2) is no longer set in the annealing process or non-oxidizing furnace oxidation furnace remove grease strip surface, either directly in the village transfer tube furnace, the strip indirectly heated to the recrystallization temperature annealing process is completed. Because the combustion gas does not contact the strip surface. Before hot-dip galvanized steel strip is very clean, and help to improve the substrate bonding strength and surface quality galvanized zinc layer.
