Description
Technical field
The present invention relates to a kind of device for preventing electric glass melting molybdenum electrode to be oxidized, being specially adapted to the electric melting furnace founding the shorter glass of material property.
Background technology
Metal molybdenum has very superior performance as the electrode materials of glass electric melting, not only high temperature resistant, and corrosion-resistant, resistance to erosion, have again lower price relative to platinum, metal current molybdenum is used widely in electric glass melting simultaneously.But metal molybdenum also also exists fatal shortcoming as high-temperature electrode material, that is exactly very easily oxidized under the environment of aerobic, therefore, when adopting molybdenum electrode to carry out glass smelting, what kind of method is taked to prevent molybdenum electrode to be oxidized into a vital problem.
The main method of current protection molybdenum electrode has air-cooled, water-cooled and inflated with nitrogen protection, takes different guard methods for different glass properties.When adopting water coolers, because the molybdenum plate cooling intensity near Shui Bao position is larger, for the glass that some material properties are shorter, start condensation when this position molybdenum electrode does not also wrap by hot glass metal completely, cause electrode roots do not wrapped completely by glass and cause anodizing to rupture.
Summary of the invention
The technical problem to be solved in the present invention is the anti-oxidant requirement that the antioxidation treatment mode of existing molybdenum electrode can not meet molybdenum electrode.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of device preventing electric glass melting molybdenum electrode to be oxidized, and comprises round metal annular electrode protection cover and packaging protection layer; Described round metal annular electrode protection cover is positioned at the molybdenum electrode root of peripheral hardware and coaxially arranges with molybdenum electrode, and it is positioned at electrode hole and bottom full weld is connected on the water coolers of molybdenum electrode; Described packaging protection layer is low melting glass powder bed, and its covering metal circular ring electrode protective sleeve also fills electrode hole completely.
By the buffer action of round metal annular electrode protection cover; isolate the molybdenum plate at close Shui Bao position; hot glass metal is made to there will not be the phenomenon having started condensation when also this position molybdenum electrode not wrapped completely; avoid and cause electrode roots do not wrapped completely by glass and cause the generation of anodizing phenomenon of rupture; low melting glass adopts existing composition than following low melting glass: SiO2:50 ~ 75%; Al2O3:1.0 ~ 15%, CaO+MgO:10 ~ 25%, R2O:5 ~ 15%.
As a modification of the present invention scheme, round metal annular electrode protection cover is high temperature alloy.
Beneficial effect of the present invention is: improve molybdenum electrode reliability in use, greatly reduces the probability that oxidation scission in use occurs molybdenum electrode; The method preventing electric glass melting molybdenum electrode to be oxidized and device too increase the whole stability of tank furnace operational process and the work-ing life of tank furnace to a certain extent, and structure is simple, easy to process, be easy to install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the method prevent electric glass melting molybdenum electrode to be oxidized to the present invention and the implementation result of device are further elaborated.
The present invention includes round metal annular electrode protection cover 1 and packaging protection layer 2; Described round metal annular electrode protection cover 1 is positioned at molybdenum electrode 3 root of peripheral hardware and coaxially arranges with molybdenum electrode 3, and it is positioned at electrode hole and bottom full weld is connected on the water coolers 4 of molybdenum electrode 3; Described packaging protection layer 2 is low melting glass powder bed, and its covering metal circular ring electrode protective sleeve 1 also fills electrode hole completely; Round metal annular electrode protection cover 1 is high temperature alloy.
By the buffer action of round metal annular electrode protection cover 1; isolate the molybdenum plate 5 at close water coolers 4 position; hot glass metal is made to there will not be the phenomenon having started condensation when also this position molybdenum electrode 3 not wrapped completely; avoid and cause molybdenum electrode 3 root do not wrapped completely by glass and cause the generation of anodizing phenomenon of rupture; low melting glass adopts existing composition than following low melting glass: SiO2:50 ~ 75%; Al2O3:1.0 ~ 15%; CaO+MgO:10 ~ 25%, R2O:5 ~ 15%.
During experiment, this device is used for founding the shorter glass of a kind of dark material property by experimenter, breaks down within the whole kiln phase without any an electrode, and work-ing life of whole electric melting furnace is increased to about 30 months by 6 ~ 8 before month.
