The invention belongs to the technology field of metal thermal treatment, which relates to the rolling technology of deformed steel used for a maglev train rail. The invention comprises the procedures in turn of rough rolling, finishing rolling, coolant-controlling and straightening, which is characterized in that two reversible mills rolling is adopted for rough rolling and the maximum rolling force of a two reversible mill is 8000 to 10000KN. And the rolling deformation should account for 60 to 90 per cent of total deformation. Three-stand universal continuous rolling line with high rollingforce and high accuracy is adopted for finishing rolling to realize mixing roll under universal mode. The invention can merely use large H-shaped hot- rolling production line to produce finished products and does not require thermal treatment and machining process, with the result that the cost can be greatly reduced and the requirement of mass production can be fully satisfied.
