Description

Technical Field

[0001] The utility model relates to the technical field of amorphous strip production, in particular to an amorphous strip drawing mechanism. Background Art

[0002] In daily life, people come into contact with two types of materials: crystalline materials and amorphous materials. The so-called crystalline materials refer to materials whose internal atomic arrangement follows certain rules. Conversely, materials whose internal atomic arrangement is in an irregular state are amorphous materials. General metals have orderly internal atomic arrangement and are all crystalline materials. Scientists have discovered that after a metal is melted, its internal atoms are in an active state. Once the metal begins to cool, the atoms will slowly arrange themselves in an orderly manner according to certain crystalline rules as the temperature drops, forming crystals. If the cooling process is very fast, the atoms are solidified before they have time to rearrange themselves, thus producing amorphous alloys. A rapid solidification process is used to prepare amorphous alloys. High-temperature molten steel in a molten state is sprayed onto a high-speed rotating cooling roller. The molten steel is rapidly cooled at a rate of one million degrees per second. It only takes one thousandth of a second to reduce the temperature of 1300°C molten steel to below 200°C, forming an amorphous strip.

[0003] During the production of amorphous strips, after the amorphous tape spraying machine produces the amorphous tape, the amorphous tape is wound by a tape reel. There is usually a certain distance between the amorphous tape spraying machine and the tape reel. If the amorphous tape spraying machine and the tape reel are not tensioned, the amorphous tape will become loose, swollen or wrinkled when wound onto the tape reel, affecting the quality of the amorphous tape roll.
