Abstract
The utility model relates to an annular crucible, belonging to the field of crucibles. The outer wall of a cylindrical crucible is fixedly connected with the bottom of the annular crucible, and the inner wall of the cylindrical crucible is fixedly connected with the bottom of the annular crucible. The annular crucible disclosed by the utility model has the advantages that the structure is novel, a crucible body is annular, the using diameter of the crucible can be more than 500mm, and the crucible can be heated through inner and outer combined heating devices, so that a thermal field is uniform, the uniformity of materials is good and the rate of finished products is greatly improved.
Description
Technical field
The utility model belongs to crucible, refers in particular to a kind of high temperature sintering and uses annular crucible.
Background technology
The employed crucible of high temperature sintering is a cylindrical shape now, and diameter is about 250mm, and diameter is big greater than the crucible radial symmetry gradient of 300mm, heating is uneven, it is not thorough to dissolve, and causes quality of materials defective, causes significant wastage.
Summary of the invention
The utility model provides a kind of annular crucible, and the thermograde that occurs in the big crucible heating process is big, heating is uneven, it is not thorough to dissolve, and causes quality of materials defective, causes the problem of significant wastage to solve.
The technical scheme that the utility model is taked is: tubular crucible outer wall is fixedly connected with at the bottom of the annular crucible, and tubular crucible inwall is fixedly connected with at the bottom of the annular crucible.
The advantage of the utility model is: novel structure, crucible body are the garden annular, and crucible uses diameter can reach more than the 500mm, can heat crucible through inside and outside combined heated device, makes thermal field even, the good uniformity of material, and yield rate improves a lot.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The specific embodiment:
Tubular crucible outer wall 1 with 2 be fixedly connected at the bottom of the annular crucible, tubular crucible inwall 3 with 2 be fixedly connected at the bottom of the annular crucible.
The material that needs heat is put into annular crucible, and the while evenly raise inside and outside the mode of heating made crucible simultaneously inside and outside the employing.
