Abstract: A method for smelting magnesium quickly and continuously includes: preparing dolomite or magnesite with reductants and fluorite at a predetermined ratio, uniformly mixing the prepared ingredients to obtain pellets, and calcining the obtained pellets in an argon or nitrogen atmosphere; continuously feeding the high-temperature calcined pellets (without being cooled) under argon protection into a reduction furnace, and performing a high-temperature reduction reaction in a flowing argon atmosphere to obtain high-temperature magnesium steam; and enabling the high-temperature magnesium steam to be carried out of the high-temperature reduction furnace by an argon flow, and performing condensation to obtain metal magnesium. The present invention eliminates a vacuum system and a vacuum reduction tank, so that quick and continuous production of the metal magnesium is realized, the reduction time is shortened to 90 min or less, and the recovery rate of magnesium is increased to 88% or more.
