Description

Technical Field

[0001] The utility model belongs to the field of amorphous alloy strip production, in particular to an online winding device for amorphous alloy strip. Background Art

[0002] Amorphous alloy strip is a new type of energy-saving material that came out in the 1970s. It is made by rapid cooling from molten steel to finished thin strips in one step. Its thickness is usually between 20 and 40 microns. This material is made by spraying molten steel containing elements such as iron, boron, and silicon on a high-speed rotating low-temperature roller. Due to the use of ultra-rapid cooling technology, the solidification speed of the molten metal is faster than the crystallization speed, thus forming a glass-like amorphous metal strip. The production process of amorphous alloy magnetic strip is mainly as follows: first, the alloy material is put into the smelting device for smelting, and then the molten alloy liquid is introduced into the tundish, and then the molten alloy liquid is uniformly guided onto the high-speed rotating cooling roller through the tundish. The molten alloy liquid is rapidly solidified into a strip-shaped amorphous alloy magnetic strip through the rapid cooling of the cooling roller, and is ejected along the tangent direction of the cooling roller under the action of inertia. It can be used after being collected into a roll.
