Magnesium reduction furnace

Magnesium metal reduction furnace is the core equipment of magnesium production. According to the different fuels used, they can be roughly divided into two categories: reduction furnaces heated by gas or heavy oil and reduction furnaces fueled by coal. Reduction furnace with gas or heavy oil as fuel Reduction furnace with gas or heavy oil as fuel, usually it is a reduction furnace with 16 horizontal tanks.

The flame enters the furnace space from the combustion chamber, bypasses the periphery of the reduction tank, and draws the burned flue gas into the branch flue at the bottom of the furnace by the drawing force of the chimney, and enters the chimney after passing through the flue and the flue gate. The secondary air is sent into the furnace through the secondary air duct through the secondary air duct on the second layer of the furnace bottom. A combustion chamber or a smoke chamber is arranged between the two reduction tanks at the bottom of the reduction furnace. Transformation of hardened carbon steel during vacuum tempering The reduction furnace is both an inverted flame furnace and a heat storage furnace. There are generally 16 reduction tanks made of nickel-chromium alloy steel in the furnace. The 16 reduction tanks are divided into four groups, that is, 4 reduction tanks form a group and are connected to a vacuum unit (the vacuum unit consists of a slide valve pump and a Roots pump), and each reduction furnace is also provided with a spare vacuum unit, so A reduction furnace generally has 5 vacuum units, and each reduction furnace is equipped with a water ring pump as a pre-pumping pump.Microstructure evolution of vacuum tempered low carbon microalloyed steel
