Abstract
A furnace lining for an industrial furnace is arranged inside a furnace shell of the industrial furnace and comprises an inner high temperature resistant layer and an outer high temperature resistant layer. The inner high temperature resistant layer is composed of a bottom laid from water penetration resistant bricks and inner linings arranged on two sides and the top, and the inner linings are inverted U-shaped structural members made from high-temperature resistant non-metal composite materials. The outer high temperature resistant layer is composed of a bottom laid from general insulating bricks, and two sides and a top laid from light high-alumina refractory fiber modules. The furnace lining for the industrial furnace provided in the utility model has the advantages of short furnace laying period, low maintenance cost, long service life of the inner linings, etc.; and can realize rapid temperature increase and temperature decrease in the furnace.
Description
Technical field
The utility model relates to a kind of industrial furnace cellar for storing things, relates in particular to a kind of industrial furnace liner.
Background technology
Industrial furnace liner is arranged in the furnace shell of industry cellar for storing things stove, comprises internal layer high-temperature-resistant layer and outer heat-insulation layer.The industrial furnace liner of prior art as shown in Figure 1, its outer heat-insulation layer 12 adopts insulating bricks to build by laying bricks or stones in furnace shell 11 inboards, internal layer high-temperature-resistant layer 13 adopts leakage proof brick or high temperature resistant brick building by laying bricks or stones in outer heat-insulation layer 12 inboards.The problem that adopts this structure and material to produce is:
1, the block stove cycle is long;
2, masonry accumulation of heat loss is bigger, and the loss of body of heater surface radiating is bigger;
3, insulating brick and leakage proof brick are all selected the light-weight brick of proportion in 0.5～0.8 scope for use, its distinct disadvantage is that the porosity is big, at the bottom of the tissue looseness, mechanical strength, anti-wear performance is poor, heat endurance is bad, slit after use a period of time between brick and the brick is subjected to displacement along with variation of temperature, cause at last that the sealing of burner hearth and heat insulating ability are serious to descend and scrap, must build furnace lining again by laying bricks or stones.
The utility model content
The purpose of this utility model in order to overcome the problem that above-mentioned prior art exists, provides a kind of industrial furnace liner with new structure exactly.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of industrial furnace liner, be arranged in the furnace shell of industrial furnace, comprise internal layer high-temperature-resistant layer and outer heat-insulation layer, be characterized in, described internal layer high-temperature-resistant layer comprises the bottom of being built by laying bricks or stones by leakage proof brick, and the liner that is arranged on both sides and top, and this liner is the whole inverted U-shaped part that adopts resistant to elevated temperatures nonmetallic composite to make; Described outer heat-insulation layer comprises the bottom of being built by laying bricks or stones by general insulating brick, and by the both sides and the top of lightweight high-alumina refractory fiber module masonry.
Described inverted U-shaped part liner both sides are plank frame, and crown center is provided with the pore that is used to be in communication with the outside, and both sides are respectively equipped with row's aperture, all are provided with reinforcing rib structure around middle pore and each aperture.
Described inverted U-shaped part liner is fixedly linked by many heat resisting steel pull bars and furnace shell.
The utility model industrial furnace liner makes it compared with prior art owing to adopted above technical scheme, has following advantage and characteristics:
1,, realized being rapidly heated and lowering the temperature of stove cellar for storing things owing to adopted thermal conductance is low, thermal capacitance is little refractory fibre module as outer heat-insulation layer;
2, owing to adopted modular structure, the block stove cycle shortens dramatically, and be normally to build 1/3rd of stove man-hour, and can in use realize badly which where changing, reduced maintenance cost;
3, improve efficiency of equipment, alleviated the weight of body of heater, simplified structure of furnace body, reduced environment temperature, improved product quality, improved working condition;
4, owing to adopted carborundum/silicon nitride composite material goods (SiC/Si
3N
4) as liner, its advantage is that thermal coefficient of expansion is little, oxidation rate is slow, and elevated temperature strength is big, and volume stability has good thermal conductivity, and the heat good stability that shakes makes the liner long service life, thereby has improved greatly the life-span of insulating layer of furnace body.

The specific embodiment
Referring to Fig. 2, Fig. 3, industrial furnace liner of the present utility model is arranged in the furnace shell 1 of industrial furnace, comprises internal layer high-temperature-resistant layer 3 and outer heat-insulation layer 2.
Cooperation is referring to Fig. 3, internal layer high-temperature-resistant layer 3 comprises the bottom 31 of being built by laying bricks or stones by leakage proof brick, and the liner 32 that is arranged on both sides and top, this liner 32 is the whole inverted U-shaped parts that adopt resistant to elevated temperatures nonmetallic composite (present embodiment is carborundum/silicon nitride composite material) to make.The both sides of this inverted U-shaped part liner 32 are plank frame, and crown center is provided with the pore 321 that is used to be in communication with the outside, and both sides are respectively equipped with row's aperture 322, all are provided with reinforcing rib structure 323 around middle pore and each aperture.Inverted U-shaped part liner 32 is fixedly linked by many heat resisting steel pull bars 4 and furnace shell 1.
Outer heat-insulation layer 2 comprises the bottom 21 of being built by laying bricks or stones by general insulating brick, and the both sides 22 and the top 23 of being built by laying bricks or stones by lightweight high-alumina refractory fiber module (this refractory fibre module can anti-1200-1600 ℃ high temperature).Between both sides 22 and furnace shell 1, also be provided with calcium silicate board with microporous 5, also be provided with refractory fiber blanket 6 around the pore between top 23 and furnace shell 1.
