Abstract：Hot- dip aluminized steel sheets are widely used for automotives, appliances and new- energy fields due to its excellent corrosion resistance, high temperature heat resistance, and light and heat reflectivity. The production flow of continuous hot- dip aluminized steel sheet is similar with CGL, but its continuous and stable industrialized production face challenges from the higher bath temperature, poor coating active and strong corrosivity on steel plate and immersion pieces of Al melt. Furnace atmosphere，Aluminum pool management, coating control and cooling after coating are the key techniques for the production of hot dip aluminized steel sheet. Technical difficulties and countermeasures of those key techniques were discussed in detail.
