Technical field
The present invention relates to a kind of cross wall structure, relate in particular to a kind of open-type anode roasting furnace cross wall structure of aluminium anode production field.
Background technology
In the aluminum anode roasting production process, the heating-up temperature of anode product surpasses 1050 ℃, as the cross wall of hopper part, also will be heated to more than 1000 ℃.After heating process was completed, so the cross wall under high-temperature, will all be lost to all heats of accumulating in atmosphere and go, and it has become the chief component of anode-baking furnace heat loss.
Present anode roasting furnace for aluminum, the structural strength that is enough to resist the thermal stress of being come by the flue wall transmission for cross wall is had, guarantee that hopper can at high temperature work, all adopt the heavy refractory material of solid to build cross wall by laying bricks or stones, in heavy refractory material on anode-baking furnace all working face, the weight of cross wall material accounts for more than 1/3.The cross wall of this structure, have the shortcoming of following several respects: 1, cross wall weight is large, has increased the load of anode-baking furnace foundation; 2, because cross wall weight is large, the amount of stored heat that produces is also large, and the heat of the cooling rear loss of stove is also large; 3, in stove heating process, cross wall caloric receptivity is large, causes heat up poor temperature uniformity in slow, hopper of hopper two ends, is unfavorable for the raising of anode product quality.
Summary of the invention
The present invention provides a kind of anode roasting oven cross-wall structure exactly in order to address the above problem, traditional anode roasting oven cross-wall is heavy to solve, given tensile load is large, build that workload is large, its accumulation of heat loss causes the problems such as anode-baking furnace hear rate height by laying bricks or stones.
In order to solve the problems of the technologies described above, the present invention is achieved in that
Anode roasting oven cross-wall structure, odd-level at cross wall is made of odd-level composite fire member and both sides solid member, establish the linear pattern dilatation joint between odd-level composite fire member and solid member, odd-level composite fire member is by odd number high temperature strength framework case and the fire-resistant inserts of low heat capacity is compound consists of; Even level at cross wall is built by laying bricks or stones continuously by even level composite fire member, be provided with the shaped form dilatation joint between adjacent even level composite fire member, even level composite fire member is by even number high temperature strength framework case and the fire-resistant inserts of low heat capacity is compound consists of, and the entity component of the both sides of even number high temperature strength framework case and even number high temperature strength framework case are integrated.
The upper surface of described odd-level composite fire member and even level composite fire member and lower surface are provided with boss and the groove with upper strata masonry and lower floor's masonry interlock.
The height dimension scope of described boss and groove is 3～50mm.
The profile width dimensions scope of described odd number high temperature strength framework case and even number high temperature strength framework case is 200～600mm; Profile gauge scope is 70～1000mm; The wall thickness dimension scope is 20～200mm.
Described odd number high temperature strength framework case and even number high temperature strength framework case are a kind of fire retarding components of hollow, and its adopts, and unshape refractory is prefabricated to be formed or through the refractory product of oversintering.
The fire-resistant inserts of described low heat capacity is lightweight unshape refractory or light-weight refractory goods.
Anode roasting oven cross-wall structure of the present invention has advantages of following several respects:
1, build the cross wall intensity and the resistance to elevated temperatures that form by laying bricks or stones good, be conducive to improve the life cycle of cross wall.
2, the composite fire construction weight is light, is easy to build by laying bricks or stones operation.
3, adopt cross wall gross weight that this member masonry of lightweight aggregate becomes to descend about 40%, the accumulation of heat loss of anode-baking furnace is significantly descended
4, simple in structure, economical and practical, easy to implement.
