Crystal taking frame convenient for taking monocrystal bar

Abstract

The invention provides a crystal taking frame convenient for taking a monocrystal bar, which comprises a base and a wooden base plate arranged on the base. Two parallel rods vertical to the base are fixed on the base, a plurality of wooden baffles are arranged between the two rods, the wooden baffles are parallel to the base, and the upper parts of the wooden baffles are provided with uniform notches. The whole crystal taking frame is designed into a cart pattern with roller wheels at the bottom, which is very convenient to carry. The operation can be completed easily now by only one person instead of the cooperation of two persons.

Description

technical field [0001] The invention relates to a crystal taking frame for placing a single crystal rod. Background technique [0002] The shape of a single crystal rod is as figure 1 As shown, the head and tail are pointed. Under the feeding amount of 60KG (18-inch thermal field), after the drawing is completed, the single crystal ingot is lowered from the auxiliary chamber of the single crystal furnace, and falls into the crystal taking frame directly below. The original crystal holder such as figure 2 As shown, it includes a steel plate base 21. There is a wooden spacer 23 of the same shape between the base 21 and the erected frame 22. The middle and upper parts are connected by a steel ring 24, and the height is about to the waist of an ordinary person. With the increase of single crystal feeding amount, there are the following problems: [0003] 1. The surface temperature of the ingot is about 100 degrees. Since the single crystal cannot be quenched (contact with m...

AI Technical Summary

Problems solved by technology

[0003] 1. The surface temperature of the crystal rod is about 100 degrees. Since the single crystal cannot be cooled rapidly (contact with metal objects), it is necessary to use wooden materials between the crystal rod and the external metal frame of the crystal frame.

Taking the conventional 6-8 inch single crystal rod as an example, the diameter difference is large, the range of wood thickness is narrow, the temperature of the single crystal rod is high, and the phenomenon of carbonization of wood occurs during use, and the 6 inch crystal rod is easy to contact with the metal on the edge. Excessive contact heat dissipation of the frame causes stress and even self-cracking, etc.

[0004] 2. From the schematic diagram of the single crystal ingot, it can be seen that the tail of the single crystal is pointed, and the ingot leans against the crystal frame. As the length of the ingot and the amount of feeding increase, the center of gravity will appear unstable, and the center of gravity will exceed the base words are more dangerous

[0005] 3. The ingot is heavy and needs two people to move it together. Sometimes it needs to be carried for a long distance, which is very difficult
