Development of domestic galvanized sheet

Development of domestic galvanized sheet
Since 1975 the United States for the first time applied to galvanized plate board 20 years of industry, the world's largest producer of developing and developed countries are trying to prevent corrosion of the goal, and considering the welding, coating properties and formability of high quality plating zinc plate board, and made a series of technological advances, including the chemical composition of the steel substrate, rolled steel surface quality, uniformity of coating thickness galvanized sheet, alloyed optimal structure and a series of process control technology problem. After 20 years of research, the above-mentioned technical problems and to complete the technical requirements of this technology and equipment have been solved and applied in large quantities on the successful application of these technologies can greatly improve the working condition, prolong life and save energy. High surface quality, high strength and profound impulse is the panel must have the basic conditions, the quality of the coating surface roughness and sheet surface quality, cleanliness, chemical composition and stamping strip has a direct relationship, while hot-dip process Zinc liquid ingredients, Redu equipment is also an important factor affecting the quality of the coating surface. High strength and high resistance and galvanized plate stamping chemical composition, physical properties, heat treatment and hot-dip board performance are closely related.
