Abstract
The present invention be directly spray into oil liquefied gas or coal gas and natural gas thereof etc. and compressed air make various ceramic bases in the atmosphere electric furnace, glaze formula burns till the testing equipment of needed atmosphere.It is characterized in that gas concentration can regulate CO concentration 0～10%, O arbitrarily
2Concentration 1～20%, and show automatically and record that temperature is controlled automatically.Simple to operate, easy to use, applicability is wide.
Description
The present invention be directly spray into oil liquefied gas or coal gas and natural gas thereof etc. and compressed air make various ceramic bases in the atmosphere electric furnace, glaze formula burns till the testing equipment of needed atmosphere.
Along with the development of ceramic industry, it is poor general that quality raw materials are tending towards, and uses inferior raw material and paid attention to by More and more factories.The firing atmosphere electric furnace is to carry out various bases, glaze formula test, opens up new requisite important high-temperature services such as porcelain kind.It (is O that the present high-temperature electric resistance furnace that uses all is confined to carry out oxidizing atmosphere
2Content is 21%) test under the condition.And the southern Production of Ceramics of China is owing to the cause of raw material composition must be burnt till under the condition of reducing atmosphere.So just make the gap between test and the production widen.A new porcelain kind puts into production and needs considerable time to debug, and the test manufacture phase is longer, so economic attrition is bigger.
In this case, some unit has carried out the trial-production of atmosphere furnace.As: the atmosphere furnace of Jiangxi Province's ceramic industry Science Institute development is made reducing atmosphere with alcoholic solution.But the furnace gas composition can not regulated at will.There are very not uniform phenomenon in atmosphere and temperature.Therefore, this atmosphere furnace can not adapt to the test of the ceramic base of various differences, glaze formula.
The object of the present invention is to provide a kind of new ceramic firing test equipment, this equipment can be made different ceramic bases, glaze formula burns till needed atmospheric condition.Make it to formulate calcining system rapidly and accurately for ceramic industry large-scale production.
Fig. 1 is the flow chart of expression one embodiment of the invention, and Fig. 2 is that the structure of expression Ma Foshi electric furnace of the present invention is formed schematic diagram.
The present invention finishes as follows. The Ma Foshi electric furnace [4] of employing take Elema as heater element, and in the back perforate [10] and [11] are used for laying temperature thermocouple [6] and probe tube [5]. At fire door [12] nozzle [3] is set and is used for spraying into oil liquefied gas and natural gas [1] thereof etc. and compressed air [2] manufacturing firing atmosphere. Make gas concentration CO in the atmosphere electric furnace, 0～10%, O2, 1～20% can regulate arbitrarily. Adjustable for reaching gas concentration, the present invention has installed flowmeter [14] and [15] at oil liquefied gas and compressed-air actuated pipeline. For making furnace atmosphere even, air admission hole [13] is designed to two sections, be taper near one section in burner hearth, one section is cylindrical outside the burner hearth.
In order to further specify advantage of the present invention, introduce an embodiment below, its technical performance and equipment are as follows:
1. electric furnace rated power: 8Kw
2. rated voltage: 380V
3. frequency: 50Hz
4. the number of phases: three-phase
5. burner hearth effective dimensions: 0.25 * 0.20 * 0.10m
3
6. temperature commonly used: 1350 ℃
7. maximum operation (service) temperature: 1420 ℃
8. gas concentration: CO:0～10%, O
2: 1～20%
9. fuel: oil liquefied gas
10. combustion-supporting gas: compressed air
11. analyzer: CD-001 series magnetic conductance formula oxygen analyzer
FF-CO infrared C O analyzer
12. flowmeter: LZB-4 0.016～0.16m
3/ h
LZB-6 0.06～0.6m
3/h
13. nozzle: SDX-1 type nozzle
Claims (3)
1, a kind of atmosphere electric furnace that is used for various ceramic bases, glaze formula firing test.It is characterized in that oil liquefied gas or coal gas and natural gas [1] thereof etc. and compressed air [2] directly sprayed into by nozzle [3] and make firing atmosphere in the trial furnace.
2, atmosphere electric furnace according to claim 1, it is characterized in that having air admission hole [13] and venthole [10].
