Description
technical field [0001] The invention relates to equipment and a method for reducing magnesium, and mainly refers to a tunnel-type double-circulation vacuum smelting furnace and a method thereof. Background technique [0002] The traditional production method of magnesium metal is mainly the Pidgeon method. In this method, ferrosilicon is used as the reducing agent, and a horizontal furnace is used. The furnace body is built on the ground with refractory bricks, and a number of reduction tanks are placed horizontally in the furnace, and the reaction material pellets are filled in the reduction tanks. Gas or oil is used as fuel, and manual loading, unloading and feeding are adopted for combustion and heating. The reduction tank is first heated by the radiant heat of the reverberatory furnace outside the reduction tank, and then the heat radiation is transferred from the reduction tank to the reaction material pellets in the tank, and then the pellets are relayed to each other....
