Pressure spray bag for use in pressured making of amorphous strip and amorphous strip making method

Abstract

The invention relates to strip making equipment for an amorphous strip, in particular to a pressure spray bag for use in pressured making of the amorphous strip and an amorphous strip making method. The pressure spray bag comprises a spray bag shell and a conveying mechanism for conveying molten steel into the spray bag, wherein a prism-shaped liquid guide cavity which is larger on the upper portion and smaller on the lower portion is formed in the bottom in the spray bag shell; the liquid guide cavity is communicated with a jet cavity below; the bottom of the jet cavity is connected with a nozzle. Molten steel enters the pressure spray bag from a liquid guide hopper through a flow guide pipe, nitrogen is added into the pressure spray bag through an air inlet nozzle, and the molten steel flows towards the nozzle under the actions of own dead weight and the pressure of nitrogen, meets a hollow structure and a copper roller into which cooling water is introduced continuously after flowing out of the nozzle, is condensed into solid momentarily, and is molded into the amorphous strip. By adopting the pressure spray bag and the amorphous strip making method, the flowing degree of molten steel is increased, molten steel flowing into the spray bag can be sprayed completely at one time, high density, uniform thickness and a small quantity of rough edges are realized, and the quality of the amorphous strip is improved.

Problems solved by technology

[0003] With the continuous improvement of living standards, electrical products continue to develop in the direction of miniaturization, environmental protection, and energy saving. In the strip making process, the density, thickness, width and other factors of the strip are greatly fluctuated by factors such as the pressure of the spray ladle, the heat dissipation of the copper roller, and the temperature of the molten steel. The consistency of the

And one of the more important factors is the pressure of the molten steel in the spray ladle during the process of making the belt. Conventional belt making relies on the weight of the molten steel itself flowing in the spray ladle and extruding from the nozzle at the bottom. Due to the limited weight of the molten steel itself, and the relatively large fluctuations in the manual pouring of the steel during the strip-making process, the depth and shallowness of the molten steel in the spray ladle are inconsistent, resulting in a low density of the sprayed strip, uneven thickness, and thinness. Therefore, it directly affects the performance of the strip, and cannot guarantee the high quality of the product.
