The utility model has the advantages that after the scheme is adopted, the actual temperature of the furnace tubes can be measured more accurately, therefore, the assurance of effectively controlling the temperature in the furnace tubes is provided, and the reduction reaction between the hydrogen gas and the WO3 in the storage boat pan in the furnace tube is carried out more sufficiently so as to produce the superfine metal tungsten powder.
Description
Technical field
The utility model relates to a kind of hydrogen reducing furnace of processing metal tungsten powder, especially a kind of hydrogen reducing furnace of processing the multipoint temperature monitoring formula of superfine metal tungsten powder.
Background technology
Processing superfine metal tungsten powder needs to satisfy four essential conditions: 1, efficient temperature control; 2, the hydrogen water content is low; 3, hydrogen flowing quantity is big; 4, WO in the boat
3Thickness of feed layer little; In these four essential conditions, the difficulty of efficient temperature control is maximum comparatively speaking, the hydrogen reducing furnace of traditional processing metal tungsten powder is owing to only be provided with Temperature Detector on the top of boiler tube, actual temperature in temperature of being surveyed and the boiler tube has very big error, thereby be difficult to temperature is effectively controlled, so the metal tungsten powder granularity that processes is big, when applying it to carbide alloy, can have influence on the intensity of alloy.
Summary of the invention
In order to overcome above-mentioned deficiency, thereby the purpose of this utility model is to provide a kind of both sides up and down at boiler tube to be provided with Temperature Detector the temperature of boiler tube can effectively be controlled the hydrogen reducing furnace of the multipoint temperature monitoring formula of the processing superfine metal tungsten powder of producing superfine metal tungsten.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the hydrogen reducing furnace of the multipoint temperature monitoring formula of processing superfine metal tungsten powder, be by cooling jacket, boiler tube, body of heater, light-weight insulating brick, heterotypic fire brick, the air feed device, the boiler tube supporter, the charge boat, calandria is formed, be positioned at the central authorities of body of heater by four boiler tubes of boiler tube support body supports, around boiler tube, be provided with heterotypic fire brick, calandria is embedded in the heterotypic fire brick, periphery at heterotypic fire brick is provided with light-weight insulating brick, the charge boat is positioned at boiler tube, and its technical essential is: be provided with pad between the boiler tube and between the heterotypic fire brick of boiler tube and bottom up and down in body of heater; Both sides up and down at boiler tube are provided with Temperature Detector; Temperature Detector adopts temperature sensor, and the calandria that boiler tube is heated is a nickel filament.
Adopt this scheme can measure the actual temperature of boiler tube more accurately, thereby, make the WO in the charge boat in hydrogen and the boiler tube for the temperature of effectively controlling in the boiler tube provides safeguard
3Reduction reaction takes place more fully, to produce ultra-fine metal tungsten powder.
The beneficial effects of the utility model are: owing to after having adopted scheme of the present utility model, can measure the actual temperature of boiler tube more accurately, thus for the temperature of effectively controlling in the boiler tube provides safeguard, make the WO in the charge boat in hydrogen and the boiler tube
3Reduction reaction takes place more fully, to produce ultra-fine metal tungsten powder.
