XG08 zinc pot production steel plate 1. brand "XG08", "WKS", "WDT0b" and German imported steel materials, mainly used for storage of zinc liquid needed. Zinc content of zinc pot is 200 tons. By controlling the composition of zinc liquid, the product has high appearance quality, mechanical processing property and some defects caused by improper control of zinc liquid composition. Rimmed steel is an incomplete deoxidizing steel. When pouring, the molten steel is boiling in the ingot mold (gas escaping), and the amount of silicon in the steel is very low. C, Si, Mn, P, S content of 2. chemical composition characteristics of the material is low, such as C < 0.08, Si < 0.03, can effectively resist the corrosion of zinc. The current hot-dip galvanizing cooker in China is usually welded with high quality low carbon steel plates such as 08F or 05F. However, due to the strong corrosion of molten zinc to steel materials, the service life of the container is very short. Generally speaking, the service life of domestic hot-dip galvanizing pan is 3 months to 2 years. 3.XG08 C Cr Mn steel chemical composition elements P Si Cu Ni in < 0.08 = 0.10 0.25-0.50 = 0.035 = 0.03 = 0.20 = 0.30 4.XG08 mechanical properties experimental yield strength tensile strength elongation contraction of each element is greater than or equal to 295MPa rate of hardness value is larger than 175MPa 35% 60% 131HB 5. steel in zinc plating of carbon: 1): the carbon content is high iron zinc diffusion reaction more intense, the greater the loss of iron loss, deterioration of alloy layer thickening adhesion. Low carbon steel in general use of 0.05~0.15. 2) silicon: high silicon content will increase the thickness of the alloy layer and form a gray coating to influence the adhesion. Rimmed steel and aluminum steel with a silicon content of less than 0.07% are used as galvanized substrates. 3) copper: Copper in steel base can slow down the pickling speed, but it has no bad effect on hot dip galvanizing, and at the same time, it can improve corrosion resistance. When manufacturing special purpose corrosion resistant galvanized sheet, it often chooses steel grade of 0.2~0.3%. 4) titanium: steel containing 0.2% titanium plays an important role in zinc plating. Titanium is the main addition element to produce low alloy and high strength galvanized steel. It plays an important role in the steel in the presence of TiC and TiN. 5) the content of manganese, sulfur, phosphorus and sulfur has little influence on the structure of zinc layer, but the content of phosphorus is about 0.15%, the zinc layer has no luster spots and the adhesion is bad. 6) aluminum: aluminum is the main additive in zinc solution, generally 0.15~0.22%, aluminum has an important effect on zinc plating: A and aluminum content reach 0.03%, which can increase zinc sheen. B and aluminum can produce an extremely thin intermediate layer of five aluminized two iron, which can inhibit the growth of the iron zinc alloy layer and increase the adhesion of the zinc layer. C and aluminum can affect the viscosity of zinc liquid and make the zinc layer thicker or thinner. D and aluminum can reduce the number of copper resistance tests. E, too much aluminum can reduce the solubility of iron in the zinc liquid, generate more zinc. 7) iron: harmful elements can increase the viscosity of the liquid zinc, the zinc layer thickness, formation of slag. The general control is below 0.05%. 8) cadmium: 0.1~0.5% can increase the zinc flower. After 0.5%, the alloy layer can be thickened and the toughness is reduced. General control is less than 0.03%. 9) lead: beneficial element, can improve the wettability of zinc liquid and increase zinc flower. Lead generally controls 0.06~0.08% when galvanizing with lead containing hot-dip galvanizing method.
