Description
Technical field
The utility model belongs to metal and establishes processing heating furnace equipment manufacturing technology field, particularly a kind of combining structure refractory fibre furnace lining device.
Background technology
The energy of the various industrial furnace consumption of China's employing at present accounts for about 1/4th of national energy total amount consumed, can be rated as power consumption first rich and influential family.And the stove that is using at present has considerable part still to belong to the product that the 50-60 of the former Soviet Union age is provided with manufacturing, and furnace lining structure all adopts fire-resistant brick system to form, this refractory brick stove, and advantage is outstanding, and is sturdy and durable, good stability; But shortcoming is also outstanding, and especially power consumption is big, and heat-insulating property is poor, and it is slow to heat up, and thermal inertia is big, and the temperature control difficulty is big etc.Along with the progress and development of science and technology, various power-saving technologies, new energy-saving material constantly occur, for condition has been created in the technological transformation of old-fashioned industrial furnace.Country proposes the notion of " green " environment-protecting industrial stove recently, and energy-conservation, sustainable development becomes fundamental state policy.The core of " green " is promptly energy-conservation, also is maximum environmental protection.
With the aluminosilicate refractory fiber is the refractory material of representative, applies in China since the beginning of the seventies, has obtained excellent effect, and all fibre furnace lining structures of using are compared energy-saving effect all between 20%-40% with old-fashioned refractory brick furnace kiln structure.But this The Application of Technology is to having experienced the quite a while really by the handy various refractory fibrous materials that utilize.China is refractory fibre big producing country, and the performance and the quality of a lot of kinds are all taken its place in the front ranks of the world.
The refractory fibrous material advantage is a lot, and thermal conductivity is low, thermal capacity is little, chemical stability is good, Heat stability is good, attractability is good and do not contain corrosive substance.Representational refractory fibrous material has following kind: 1, plain edition aluminosilicate fiber cotton and goods thereof: heat resisting temperature reaches 1260 ℃;
2, high-purity type aluminosilicate fiber cotton and goods thereof: heat resisting temperature reaches 1260 ℃;
3, high alumina type aluminosilicate fiber cotton and goods thereof: heat resisting temperature reaches 1400 ℃;
4, contain zirconium-type aluminum silicate cellucotton and goods thereof: heat resisting temperature reaches 1400 ℃;
5, polymorphic mullite fiber cotton and goods thereof: heat resisting temperature reaches 1450～1500 ℃.
At present; Industrial furnace all adopts various refractory fibres to make furnace lining; And a lot of in the mode of different its moulding of application scenario, general commonly used method has: mull technique, vacuum forming, spray mo(u)lding method, fibrofelt shaping method to suppress, be pressed into building block construction from part or the like.Yet, with regard to shaft furnace, be the best with the fibrofelt shaping method to suppress.
Traditional fibre furnace lining is a monolithic construction, and service life, energy-saving effect will obviously descend more than 3 years, and the liner fibrage wears out, becomes fragile; Energy-saving effect own descends about 10%, always be that integral body changes new furnace lining into, and outer field refractory fibre is low because of operating temperature; Performance is as excellent as before, has to change together, and this just very wastes fibrous material; Really unfortunate, this is also with regard to corresponding increasing production cost.
