It is understood that high quality PPGI prepainted galvanized steel coil is divided into two types of products: high-strength board and deep-drawing board. Faced with the strict requirements of customers on product performance indicators, technicians take root in production lines, solve technical problems, and rely on national-level enterprise technology centers and national physical and chemical inspection centers to continuously strengthen key indicators research and experiment of automobile plate strength, forming and welding.
When producing high-strength galvanized sheet, the technicians actively docked the market on the basis of stable production of 600MPa grade dual-phase steel and developed 800MPa grade high-strength steel. When producing deep-dip galvanized automotive panels, technicians overcome the problems of high elongation and high surface quality of the products, especially the ultra-deep O5 board surface requires zero defects. The technicians specially formulated the production guarantee measures: before the production, the whole line cleaned the roll surface and carefully checked the defect source; in the production, the surface quality was checked by means of the meter; after the product was off the line, the product was manually polished and then the product was inspected to ensure the product. Surface Quality.
The company's O5 board has produced and sold more than 1,000 tons for two consecutive months, and the contract fulfillment rate has reached 100%. Automobile panels have become suppliers and service providers of many well-known automobile manufacturers at home and abroad, and the products are moving towards high-end, high-quality and brand-oriented.
