The present invention relates to a lifespan-extended reinforced structure of a magnesium heat reduction reaction tube capable of extending a lifespan of a reaction tube, reducing costs, and improving productivity through insulation or rib reinforcement. The present invention, regarding a magnesium heat reduction reaction tube, includes a lower discharging outlet prepared on a lower end of the reaction tube for discharging a raw material remaining after the heat reduction tube; an upper thermal stress concentration portion, positioned on an upper portion of the reaction tube, exposed to the atmosphere to receive a thermal stress; a lower thermal stress concentration portion, positioned on a lower portion of the reaction tube, exposed to the atmosphere to receive a thermal stress; and thermal stress reduction instruments prepared on the upper and lower thermal stress concentration portions to reduce the thermal stresses of the upper and lower thermal stress concentration portions. |
