Description
Technical field
The invention belongs to complex phase thermal storage refractory technical field.It is resistance to more particularly to a kind of alloy-oxide complex phase accumulation of heat
Fiery material and preparation method thereof.
Background technology
Refractory material directly applies to steel, coloured, cement, glass, ceramics, chemical industry, the height in the mechanically and electrically field such as power
It is the basic material for ensureing that above-mentioned industry operation and development are essential in temperature industrial production process.China is energy consumption big country, with
The anxiety of environmental requirement and fuel supply, energy-saving and emission-reduction oneself great technological improvement engineering is classified as by country.Heat accumulating type waste heat
Recovery technology 19th-century mid-term begins to be used for that the scale such as glass furnace, blast funnace hot blast stove, open hearth and coke oven is big and temperature is high
Stove.
In recent years, the heating furnace in China will develop rapidly to the direction of recuperative heater, except newly-built heating furnace will be more
Come outside more use regenerative heat technologies, heating furnace online at present also will progressively transform recuperative heater as.In order to adapt to
This change, further improves the performance of recuperative heater refractory material, and recuperative heater will with refractory material
Further it can be developed and be applied.Recuperative heater energy-saving effect is notable, it is environmentally friendly protection and raising steel into
Material rate, it is the prior development direction of modern the latter period heating furnace.
Since nineteen nineties, obtain to enter greatly very much in the research of regenerative combustion technology and application aspect in the world
Exhibition, energy-conservation and environmental protection are combined, are promoted to " HTAC（HTAC）”.Japan will apply heat storage type combustion skill
The industrial furnace of art is referred to as " high performance industrial furnace ", is classified as the great new industrial research problem of country and application, and obtains notable
Effect.On soda-lime-silica glass kiln, the temperature that flue gas leaves flame space is very high（Up to more than 1400 DEG C）, flue gas is so
Kiln is left at high temperature, substantial amounts of heat will be taken away, typically account for the 50~70% of kiln heating load.Therefore, it is raising
The thermal efficiency of kiln, reasonable energy utilization, all with waste heat utilization equipments such as regenerator in the structure design of glass furnace.Together
When, to reach flame temperature required in kiln, in addition to the heat energy that fuel combustion provides, also need to preheat combustion air,
This is also one of free-revving engine for introducing regenerator.
