Black Annealed Iron Wire, mostly written as Soft Annealed Wire, Annealed Iron Wire or just Annealed Wire. This kind of steel wire offers excellent flexibility and softness due to its oxygen free annealing process. Our annealed wire products are mostly used as tie wire or material for weaving wire mesh.

Treatment of waste residue in titanium dioxide production
Titanium White Production of sulfuric acid in the waste acid is mainly residue after sedimentation solution, the main ingredient is not decomposed iron ore of titanium, rutile, zircon, gangue, mud and sand, ferrous sulfate, sulfuric acid, and the free portion soluble titanium (TiOSO 4), is generally washed with water (neutralization with lime or), filtered, pressed dry made after inorganic waste, coal slag or blended with sub-brick.
The US Environmental Protection Agency stipulates that the allowable content of heavy metals in sludge fertilization is: Cd10mg/kg, Mo1000mg/kg, Hg10mg/kg, Ni200mg/kg, Pb1000mg/kg, Zn2000mg/kg, acid hydrolysis residue from a domestic plant (using Liangguang Mine) test The results were lower than this standard: Fe 2 O 3 14.9%, A1 2 O 3 22.93% CaO 8.47%, MgO 6.3%, CdO 2.8 mg / kg, Mo 36.2 mg / kg, PbO4 3.5 mg / kg, NiO55. 7 mg/kg, ZnO 49.4 mg/kg, and Hg were absent.
The acid-decomposed waste residue can also be returned to the ilmenite for re-acidification. In China, there have been examples of re-acidification of the acid-decomposed waste residue in the factory, but too much application affects the whiteness of the product, and TiO in the slag (dry basis) When the content is less than 40%, there is no need to return to continue use. Recently, it has been reported that Saatchi, Germany, has about 50% of acid-decomposed waste residue containing TiO 2 , which is blown into a steel-making furnace in a steel-making plant, and finally sintered on the inner wall of the furnace, which can greatly extend the steel-making furnace refractory brick. The service life of the lining.
