Abstract
The utility model relates to a single crystal fused aluminum oxide ingot mould. The utility model is characterized in that the cavity of the aluminum oxide ingot mould is in a cone shape. Because the cavity of the aluminum oxide ingot mould is transformed into the cone shape from the square shape, the utility model prevents the aluminum oxide ingot mould from cracking when the angular parts are under the effect of the stress in the mould, thereby greatly prolonging the long service life of the aluminum oxide ingot mould.
Description
Technical field:
The utility model relates to a kind of monocrystalline fused alumina ingot mould.
Background technology:
In monocrystalline fused alumina production process, ingot mould is the main container of material at electric furnace fusion back melt material, and material becomes solid fine grain from liquid crystals in this container.Because the continuous effect of high-temperature fusant, existing square ingot mould expanded by heating, the bight is vulnerable to the concentrated of die body internal stress to be compiled, and occurs cracking phenomena (shown in the A portion of Fig. 1) easily in this bight, cause melt excessive, shortened the work-ing life of ingot mould greatly.
Summary of the invention:
The purpose of this utility model is to provide a kind of monocrystalline fused alumina ingot mould, and this monocrystalline fused alumina ingot mould is simple in structure, reasonable in design, the work-ing life that helps improving the aluminum oxide ingot mould.
The utility model monocrystalline fused alumina ingot mould is characterized in that: aluminum oxide ingot mould die cavity is circular cone shape.
The utility model because by with aluminum oxide ingot mould die cavity by the square truncated cone that makes into, thereby avoided the aluminum oxide ingot mould to be subjected to the generation of the easy cracking phenomena of die body internal stress effect in the bight, thereby improved greatly the work-ing life of aluminum oxide ingot mould.
Description of drawings:
Fig. 1 is the organigram of existing aluminum oxide ingot mould;
Fig. 2 is an organigram of the present utility model.
Embodiment:
The utility model monocrystalline fused alumina ingot mould 1, aluminum oxide ingot mould die cavity 2 is circular cone shape.In order more to help preventing the be heated problem of back stress concentration of die body, aluminum oxide ingot mould profile also is circular cone shape, and aluminum oxide ingot mould wall thickness equates or unequally all can.
The utility model by with aluminum oxide ingot mould die cavity by the square truncated cone that makes into, help eliminating the be heated problem of back stress concentration of die body, thus the work-ing life that helps improving the aluminum oxide ingot mould.
