Preparation method and device for alloy tubular product with controllable diameter and wall thickness

Abstract

The invention provides a preparation method and device for an alloy tubular product with controllable diameter and wall thickness. The preparation device comprises a liquid alloy melt generating unit,a mould and a tubular product forming component. The mould is provided with a mould cavity. The tubular product forming component is installed in the mould cavity so that a cavity for preparing the alloy tubular product is formed between the outer surface of the tubular product forming component and the inner surface of the mould. The liquid alloy melt generating unit can provide a liquid alloy melt to the cavity so as to prepare the alloy tubular product. The liquid alloy melt can be adhered to the inner surface of the mould and / or the outer surface of the tubular product forming component.The method comprises the following steps: providing the liquid alloy melt for the cavity so as to prepare the alloy tubular product, and separating the alloy tubular product from the mould. The preparation method and device can be used for preparing the alloy tubular product with the controllable and uniform diameter and wall thickness, especially a non-crystal alloy tubular product.

Description

technical field [0001] The invention relates to the technical field of alloy pipes, in particular to a preparation method and device for alloy pipes with controllable diameter and wall thickness. Background technique [0002] Alloy pipes, especially amorphous alloy pipes, have important applications in engineering due to their advantages of high strength, high hardness, high elastic limit and excellent corrosion resistance. Due to the physical properties of some alloy materials, especially amorphous alloy materials, there are special difficulties or special restrictions in the production of their tubes. [0003] Such as figure 1 What is shown is a casting scheme of an alloy pipe, especially an amorphous alloy pipe, in the prior art, in which a molten alloy melt 12 is placed in a quartz container 11 . The lower end of the quartz vessel 11 has a melt outlet 13 . The caliber of the melt outlet 13 is small enough that the effect of surface tension is sufficient to prevent the...

Problems solved by technology

[0006] The preparation of pipes by this method requires more alloy raw materials than the actual materials used, and the remaining liquid alloy melt 16 falls out from the lower end of the cavity 15, resulting in a waste of alloy raw materials, especially for the preparation of amorphous alloy pipes. Expensive, difficult to prepare, and repeated use have a certain impact on the forming of amorphous alloy tubes;

[0007] In addition, the inner diameter of the pipes that can be made by this method is uncontrollable and the thickness of the inner diameter pipe wall is uneven; Form continuous large outer diameter alloy pipes, especially amorphous alloy pipes
