The invention relates to a process for heating continuous casting slabs by a regenerative roller-hearth type heating furnace and belongs to the technical field of process for heating slabs by a heat-accumulation heating furnace. The process is used for rapidly heating continuous casting thin slabs. According to the technical scheme, the various functional segments of the roller-hearth type heating furnace are divided into a first heating section, a second heating section, a third heating section, a slab traversing section and a thermal-insulation section, a regenerative combustion technology is adopted in each section, and the temperature of the first heating section as a main heating section is raised to 1230 DEG C, the temperature of the second heating section as an auxiliary heating section is raised to 1210 DEG C, the temperatures of the other sections are also raised to 1190 DEG C, the soaking process is completed, and the final tapping temperature is 1180+/-5 DEG C. According to the ...
