Abstract: Based on the continuous annealing process and system analyses for cold-rolled stainless steel, the heating system of continuous annealing furnace was designed, and the furnace length configuration and the combustion power configuration were respectively calculated by the surface energy balance equation and the energy conservation equation. By comparison and analysis of the actual calculation example and the actual operation, it verifies that the design method is effective and has the ability to complete the design process from the product outline and process analysis basis to the unit heating system integration, arrangement and overall arrangement of equipment. Thus, it provides a theoretical basis for the secondary model of the heating system of the cold-rolled stainless steel continuous annealing furnace.

Key words: cold-rolled stainless steel, continuous annealing furnace, heating process, system design
