At present, there are many types of magnesium reduction furnaces used in China.

From the perspective of energy saving and high efficiency, it is more common to choose a regenerative magnesium reduction furnace.

[0003] The existing magnesium reduction furnace generally lacks effective temperature monitoring and regulation devices. In the process of magnesium being taken out of the furnace, in order to ensure the quality of magnesium, operators often adopt a conservative strategy, maintaining a continuous supply of fuel even when there is no reduction reaction, which is the so-called "empty burning" state, which will cause a waste of resources, and the temperature is cooled down to the starting temperature only after the furnace is finished, which takes a lot of time, and the combustion temperature control in the furnace is not flexible, which easily leads to the problem that the life of the reduction tank is generally too short and the quality of the finished magnesium is not high.
