Matrix metal iron in the solid state solution of zinc atoms to form a crystal, is the integration between the two metal atoms, the atoms gravity is relatively small. Therefore, when the zinc reached saturation in solid solution, zinc, iron atom interdiffusion of two elements, spread to (or called infiltration) iron matrix zinc atoms migrate in the matrix lattice, and gradually form an alloy with iron. Supply galvanized bolts, fasteners Yongnian County Bowen professional processing galvanized bolts, we have advanced technology of hot-dip zinc screw parameters, excellent equipment, high-tech assembly line, is a professional supplier of hot dip galvanized bolts, reasonable price, complete specifications, allowing you to buy the rest assured useful products. First, hot-dip zinc electrolytic degreasing screws, then washed, dried, and then by a protective gas reduction furnace recrystallization annealing the hot-dip zinc screw machining, and finally into the zinc galvanizing pot in a sealed case. This approach because the strip does not pass through an oxidizing furnace heated, the surface of the thin oxide film, the reduction furnace can be appropriately reduced hydrogen content in the protective gas.
