Abstract
The invention relates to a double-row tank magnesium reduction furnace in the field of non-ferrous metal metallurgy, in particular to a bearing structure of an upper tank of the double-row tank magnesium reduction furnace, which consists of upper tank supporting bricks and lower pedestal lattice bricks, wherein, the upper tank supporting bricks take a shape of saddle, while the lower pedestal lattice bricks are twin type connected by a base. The invention solves the problems of poor strength of bearing bricking-up structure of the upper tank, easy damage, largely shielding heating to the lower part of a reduction tank, uneven heating of materials in the tanks, small flowing section of smoke in the furnace, uneven temperature in the furnace, and the like.
Description
Technical field
The double tank magnesium reducing furnace that the present invention relates to smelting field of nonferrous metal, particularly relates to a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, in order to improve inner flue gas of the stove, flows and being heated evenly property of tank body, improves material reduction output capacity in tank; Increase the stability of upper strata tank supporting masonry, the service life of improving reduction furnace.
Background technology
Upper strata tank supporting structure is the important component part of double tank magnesium reducing furnace, its Main Function is at reduction furnace internal support magnesium-reduced tank body, guarantee at high temperature thermally equivalent of tank body, make material in tank at the temperature of technique initialization, complete smoothly reduction reaction, until magnesium steam is excessive to condensing zone crystallization.Magnesium-reduced technological requirement upper strata tank supporting structure intensity is good, can resist and take on the thrust that tank operation brings, and also will under the indeformable condition of tank body, dwindle supporting structure being as far as possible heated of tank body covered guaranteeing.
Existing supporting construction for upper layer tanks of double row tank magnesium reducing furnace, all adopt common standard type laying fireproof bricks, the shortcoming with following several respects: 1, structural strength is poor, very easily layering in taking on tank operating process, comes off and even topples over, and causes tank body distortion until affect the normal production of reduction furnace; 2, supporting masonry section is large, has seriously covered the heating surface of tank body lower part, causes in tank the material inequality of being heated, and has reduced magnesium-reduced output capacity; 3, due to the layout feature of double tank, between lower floor's tank body and upper strata tank supporting masonry, spacing is little, has reduced the cross section of flue gas circulation, causes flue gas circulation not smooth, has worsened the working of a furnace, has reduced the heat capacity of stove; 4, because supporting masonry has occupied larger burner hearth area, cannot stay equably and establish lower furnace exhaust smoke hole, cause the interior temperature of stove dead angle many, furnace temperature is inhomogeneous, has seriously affected material reduction output capacity in tank.
Summary of the invention
The present invention in order to solve the problems of the technologies described above, provide exactly a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, object be solve upper strata tank supporting masonry structure intensity difference, fragile, reduction tank bottom is heated and covers in large, tank the material problems such as inequality, inner flue gas of the stove flow area is little, furnace temperature is inhomogeneous of being heated.
In order to solve the problems of the technologies described above, the present invention is achieved in that a kind of supporting construction for upper layer tanks of double row tank magnesium reducing furnace, it is characterized in that consisting of top holder tank brick and lower base checker brick.
Described top holder tank brick is saddle type.
In the middle of described top holder tank brick, be provided with reinforcement.
The cross section of described reinforcement is any one in ellipse, rectangle, circle or polygon.
The side of described top holder tank brick is for being provided with spill guide face.
Described spill guide face is any one in lonely shape curved surface, lonely phase cross surface, obtuse angle phase cross surface or right angle intersection face.
The double type of described lower base checker brick for being connected by base.
The base of described lower base checker brick is provided with smoke evacuation grid hole.
The shape in described smoke evacuation grid hole is any one in square, rectangle, circle or polygon.
Described top holder tank brick is that brickwork joint is connected or special form brick connects with lower base checker brick.
Described brickwork joint connects or special form brick to connect be that mother-son mouth adds refractory wass and is connected.
The female mouth of described bond is located at the bottom of top holder tank brick.
Described bond rim of the mouth is located at the top of lower base checker brick.
Described mother-son mouth shape is any one in semicircle, circular arc, trapezoidal, rectangle or triangle.
Supporting construction for upper layer tanks of double row tank magnesium reducing furnace of the present invention has the following advantages:
1, due to what adopt, be special form brick Integral combined structure, the masonry structure forming has been cancelled most of construction joint, and between special form brick all with the mutual bond of form of mother-son mouth, so good integral strength, can at high temperature resist well the lateral thrust that reduction furnace forms in taking on tank operation, be conducive to extend the service life of whole stove.
2, designed top holder tank brick and lower base checker brick brick body cross section is little, but the fulcrum to tank body is many, both dwindled the covering of tank body lower part heating surface, can reduce tank body temperature distortion again, the interior material of tank is heated more even, is conducive to improve the reduction output capacity of material in tank.
3, because the sidepiece at supporting construction for upper layer tanks of double row tank magnesium reducing furnace has adopted the design of spill guide face, effectively expand burner hearth flue gas flow area, improved the working of a furnace, can improve the heat capacity of reduction furnace, and then improved the production capacity of reduction furnace.
4, because lower base checker brick have smoke discharging function, can make at the bottom of reduction furnace cigarette hole arrange more even, effectively eliminate temperature dead angle in stove, whole fire box temperature uniformity coefficient is obviously improved, and then improve material reduction output capacity in the tank of reduction furnace.
