Detailed Product Description: | US grid control galvanized to reduce dross US grid galvanized zinc dross is necessary to reduce the amount of iron in molten zinc content, factors that begin from the reduction of dissolved iron: ⑴ plating and insulation to avoid iron The dissolution of the Peak District, which do not carry out operations in 480 ~ 510 ℃ when. ⑵ zinc pot carbonaceous material is used wherever possible, low silicon content of steel welding. High carbon content, the zinc solution to wok erosion will accelerate, high silicon content can cause corrosion of zinc liquid iron. The current use of 08F quality carbon steel. Its carbon content 0.087% (0.05% to 0.11%), silicon ≤0.03%, and containing iron can be suppressed by etching the elemental nickel, chromium and the like. Unavailable ordinary carbon steel, otherwise consume a large amount of zinc, zinc short pot life. It was also proposed to manufacture silicon carbide molten zinc tank, though resolve core loss, but the molding process is also a problem. ⑶ should always slag. First temperature to process temperature limit for dross and zinc liquid separation, and then dropped to the process temperature, so that after the bottom dross Shen fish with a spoon. Fall into molten zinc plating also timely salvage. ⑷ To prevent fluxing iron zinc into the groove of the workpiece, the compound fluxing agent will have some time to generate red-brown iron, the US grid, should be regularly filtered. Fluxing agent to maintain the pH at about 5 as well. ⑸ plating of aluminum is less than 0.01% will accelerate the generation of sediment, the amount of aluminum zinc solution not only improve mobility, increase the coating brightness, but also help reduce dross, zinc ash. A small amount of aluminum floating in the liquid in the face to reduce oxidative beneficial, too much influence the coating quality, resulting in the phenomenon of missing spots. ⑹ heating, heating should be uniform, to prevent burning and overheating burst. US grid welding machine used cautiously then zero protection Most welders US grid plant low-voltage distribution system grounding TN system commonly used, including plastic US grid, namely the low-pressure side of the transformer neutral point directly grounded star, electrical equipment may be exposed conductive portion connected through the protection line or neutral line and neutral (ground). US grid welders welding plant for use in such a system should be used to protect access to the natural zero measure. Welding pick zero into two parts: one to prevent accidental shorting the housing shell hit then zero, the second is to prevent welding machine breakdown fleeing the primary high-voltage secondary side of the secondary coil connected to zero (zero line should be connected with one end connected to weldment). After welding the two parts then theoretically zero to ensure welder without touching a high voltage (380/220 volt supply voltage means), but the actual work in the secondary coil connected to zero and it will attract some insecurity, must be careful use. Because the welding secondary coil then zero, if the weldment and the earth is not insulated or welding cable sheath damaged touch, the aluminum the US grid, welded wire loop once is bad, the US grid fence, there will be a huge welding current By land, protection of the zero line and the welding wire to form a new circuit, the welding current directly fuse the zero line, easy to cause fire, if the fuse is then zero lines, but also undermine the entire low voltage power supply system. US grid, built through mesh, the US grid plastic bag provided by the City Building Materials Co. Jiantong screen. US grid, built through mesh, the US grid plastic bag is Dongguan Jian Tong Screen Materials Co., Ltd. (www.dghuaxiasw168.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image on the telephone, to obtain the latest information, contact: Liu Liandong. |
