Description
Technical field
The utility model relates to a kind of reduction furnaces.
Background technique
Currently, 15 pipe reduction furnaces are using hydrogen as reducing atmosphere, for the production requirement of tungsten (molybdenum) powder, in setting
Under the conditions of technological temperature, tungsten oxide (molybdenum) powder materials are restored, 15 pipe reduction furnaces are to introduce from Germany China's nineties
14 pipe reduction furnace technologies on the basis of digest and assimilate and continuously improve the equipment of new generation that developed.Former 15 pipes reduction
Furnace directly facing high temperature is that high aluminum fiber folds block, it is a kind of fibrous structure, at high temperature with using prolonging for time
Long, fiber, which folds block, can occur powder phenomenon-tion, and insulating layer will be more and more thinner, and heat insulation effect will be deteriorated, and the energy consumption of equipment is just
It can be increasing.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of reduction furnace, it
Powder phenomenon-tion will not occur at high temperature for insulating layer, and service life greatly prolongs, and play good energy-saving effect, extend and set
The maintenance cycle of standby heat preservation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of reduction furnace, it includes furnace body, institute
The furnace chamber that furnace body is provided with furnace wall He is arranged in furnace wall is stated, the furnace wall includes wing furnace wall, and the wing furnace wall is by nearly oven cavity side
It is disposed with mullite brick layer, insulating layer and side wall body layer outward.
Further, the insulating layer has insulation fibre cotton layer.
Further, the insulation fibre cotton layer is provided with two layers, respectively high aluminum fiber cotton layer and aluminosilicate fiber cotton layer.
Further, the furnace body is provided with substrate in the bottom for surrounding furnace chamber.
Further, the substrate is made of light-weight brick.
Further, the furnace body is provided with top furnace wall surrounding at the top of furnace chamber.
Further, the top furnace wall is also equipped with insulating layer, and the insulating layer has two layers of insulation fibre surface layer, by introversion
It outside successively include high aluminum fiber cotton layer and aluminosilicate fiber cotton layer.
Further, boiler tube group is provided in the furnace chamber, the boiler tube group includes the multiple boiler tubes being set side by side, Mei Gelu
Pipe group is correspondingly arranged on thermocouple.
Further, at least two row boiler tube groups, the boiler tube group are disposed in the furnace chamber from the bottom to top to be correspondingly arranged
There is fire brick layer, and the lower section of corresponding boiler tube group is arranged in the thermocouple, the fire brick layer is arranged in corresponding furnace
The top of pipe group.
After above-mentioned technical proposal, the utility model adds one layer of mullite brick layer before insulating layer, due to increasing
Mullite brick layer, makes insulating layer that powder phenomenon-tion will not occur at high temperature, and insulating layer can also suitably be thickeied, heat preservation effect
Fruit can be more preferable, and service life also greatly prolongs, and plays good energy-saving effect, also extends the maintenance cycle of insulation of equipment,
Many maintenance costs are saved for client.
Detailed description of the invention
