Description

Metal magnesium reduction furnace

Technical field

The utility model belongs to the stove of making MAGNESIUM METAL.

Background technology

Metal magnesium reduction furnace is important thermal technology's production unit of making MAGNESIUM METAL, working temperature is 1200-1400 ℃ in this reduction furnace reduction jar working spaces and combustion chamber, for can be high temperature resistant, the furnace roof of present this reduction furnace and top, combustion chamber are all adopted refractory brick to build by laying bricks or stones and are formed, its shape is vault construction, though refractory brick has resistant to elevated temperatures characteristic and since refractory brick build by laying bricks or stones the vault that forms cold and heat succeed each other and

Easily produce under the hot environment and burst apart and high temperature creep, the brick generation is peeled off cause furnace roof and top, combustion chamber to cave in, therefore this reduction furnace is shorter work-ing life.

Summary of the invention

The purpose of this utility model is: the metal magnesium reduction furnace that a kind of long service life is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of metal magnesium reduction furnace, comprise furnace wall, flue, fire in a stove before fuel is added hole, reduction jar, combustion chamber and column, be fixed with joist on the column, be equipped with on the joist and the joining lifting part of hanger brick one end, the other end and the furnace roof that are positioned at the intravital hanger brick of stove connect firmly, and the other end and the top, chamber, combustion chamber that are positioned at the hanger brick of combustion chamber connect firmly.

Described lifting part is made up of hanging beam and suspension ring, and hanging beam is contained on the joist, and suspension ring are supported by hanging beam, and an end and the suspension ring of hanger brick link.

Furnace roof and top, chamber, combustion chamber all are to be made by refractory material casting, all are cast for one with the hanger brick lower end.

Furnace roof and combustion chamber top is the pinnacle that there is obliquity on mind-set both sides therefrom, and is gapped between furnace roof and the furnace wall.

Furnace roof and top, combustion chamber are template top, plane, and be gapped between furnace roof and the furnace wall.

The furnace roof of this metal magnesium reduction furnace and combustion chamber top all connects firmly mutually with hanger brick and an end of hanger brick and the lifting part that is contained on the joist connect mutually, furnace roof and top, combustion chamber are a whole plate structure, therefore they have hot performance preferably, overcome because of temperature in the stove colds and heat succeed each other and the damage on the furnace roof that causes of pyroplastic deformability and top, chamber, combustion chamber, so the reduction furnace long service life of this structure.
