Abstract

The utility model discloses a hollow seed crystal rod, which comprises a seed crystal rod main body, and is characterized in that a hanging bracket connected with the outside of a furnace is arranged at the upper end of the seed crystal rod main body; a clamping slot for assembling a seed crystal is formed at the lower end; the seed crystal is inserted into the clamping slot; the cylindrical seed crystal rod main body is made of an iraurita material; and the inner part of the seed crystal rod main body is vacuumized. The hollow seed crystal rod has the advantage of simple structure, is used safely and can change the heat conduction rate and effectively protect the temperature fluctuation of a temperature field.

Description

A kind of open core type seed rod

Technical field

The utility model relates to a kind of seed rod, relates in particular to a kind of open core type seed rod, is mainly used in the production seed body.

Background technology

Seed rod is one of imperative equipment of produce single crystal; Because the continuous rise in price of noble metal, the shared production cost of iraurite seed crystal in the monocrystalline production also can't neglect, and seed rod in the past all is to process through iraurite; Again because in the past seed rod all is solid as shown in Figure 1; So, tightly in process of production the thermal conductivity of seed body is increased, and cost is than higher.Because the height suitable to temperature requirement when producing seed body, and aspect temperature equalisation, require also very highly, and the seed rod of the sort of solid mode in the past is higher to the thermal conductivity of seed body; Though seed rod is in stove; But the parts that link to each other with seed rod are outside stove, again because seed rod in the past is solid, so; The outer temperature of stove will soon conduct on the seed body in the stove through seed rod, and the seed crystal that causes producing is difficult to up to standard.

The utility model content

In order to overcome the defective of above-mentioned prior art, the utility model provide a kind of simple in structure, safe in utilization, can change thermal conduction rate simultaneously, can effectively protect the fluctuation of warm temperature.

The utility model technical problem to be solved adopts following technical scheme to realize:

A kind of open core type seed rod comprises the seed rod main body, it is characterized in that: the upper end of described seed rod main body is provided with the suspension bracket that links to each other with stove outward, and the clip slot that seed body is installed is established in the lower end.

Assigned seed body in the described clip slot.

Described seed rod main body adopts the iraurite material to process, and is shaped as right cylinder, its inner sealed vacuum that forms.

The beneficial effect of the utility model is:

Simple in structure, safe in utilization, the while can change thermal conduction rate, can effectively protect the fluctuation of warm temperature.

Embodiment

For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 2, a kind of open core type seed rod comprises seed rod main body 1, and the upper end of seed rod main body 1 is provided with the suspension bracket 2 that links to each other with stove outward, and the clip slot 4 that seed body 3 is installed is established in the lower end.

Assigned seed body 3 in the clip slot 4.

Seed rod main body 1 adopts the iraurite material to process, and is shaped as right cylinder, its inner sealed vacuum that forms.

More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments, and the principle of describing in the foregoing description and the specification sheets that the utility model just is described is under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
