Abstract

The invention provides a crystallizer which is mainly used for preparing amorphous alloy. The amorphous crystallizer is composed of a copper sleeve 5, a copper sleeve support 3 and a rotary spindle 1; when the crystallizer works, cold water flows in from a water inlet end of the rotary spindle and flows into the copper sleeve 5 along the pore channels in the rotary spindle 1 and the copper sleeve support 3; the cold water absorbs the heat of molten steel transferred from the outer surface of the copper sleeve; and then the hot water returns to a water outlet end in the rotary spindle from the copper sleeve support 3 at the other end of the copper sleeve 5 along the path opposite to the cold water and flows out so as to circularly cool the molten steel. The crystallizer provided by the invention has the advantages that: the cooling efficiency is high, the surface temperature of the copper sleeve is uniform, a water flow dead angle does not exist in the copper sleeve, the axial cooling of the copper sleeve is uniform, the mechanical performance is good, and the working precision is high; and the heat transfer effect of applying the amorphous crystallizer to cool the molten steel is guaranteed.

Description

Technical field: [0001] The invention relates to a crystallizer, in particular to a crystallizer for producing amorphous alloy. Background technique: [0002] Amorphous alloys are solidified by ultra-rapid cooling. When the alloy is solidified, the atoms do not have time to arrange and crystallize in an orderly manner. The obtained solid alloy has a long-range disordered structure, and there are no grains and grain boundaries of the crystalline alloy. [0003] The production technology of amorphous alloy is to pour 1300 ℃ alloy steel on the high-speed rotating water-cooled copper sleeve, and instantly cool it to below 200 ℃ to form amorphous alloy. [0004] The immature structure and parameters of the existing domestic and foreign crystallizers, and the diversification of the cooling structure make the experiment of preparing amorphous alloys unscientific, resulting in the failure of various water-cooling structures, but summing up its experience, the structure and design of...
