Problems solved by technology

Then the shot-peening processing method in the above-mentioned literature mainly considers the solidity of the combination between the base material and the subsequent coating material, and its shot-peening treatment is to prepare for the subsequent coating process, and does not involve the fusion of the base material and the amorphous alloy. The wettability relationship of the liquid, the only consideration factor is the roughness index, and the microstructure and shape of the substrate surface are not considered, so it is not suitable for processing the surface of the cooling roll

Abstract

The invention discloses a cooling roller surface processing technology comprising the steps of (1) cutting the surface of a roller sleeve of a cooling roller to remove an unsmooth part which can be observed through naked eyes; (2) fixing the roller sleeve on a rotating shaft, and enabling the roller sleeve to rotate; (3) carrying out shot blasting treatment on the surface of the rotating roller sleeve; (4) carrying out rolling treatment on the surface of the rotating roller sleeve in a mechanical rolling way; (5) carrying out ultrasonic treatment on the surface of the roller sleeve by using an ultrasonic vibration generator before the cooling roller is used. An amorphous strip obtained when an applicant prepares the amorphous strip by using the cooling roller treated by combining the three processes including shot blasting treatment, mechanical rolling and ultrasonic treatment in the process of processing the surface of the cooling roller is good in surface smoothness and continuity, few in product flaws as well as good in strip stability and strip thickness uniformity.

Description

technical field [0001] The invention relates to a metal surface processing technology, in particular to a cooling roller surface processing technology, which belongs to the technical field of metal surface treatment. Background technique [0002] The principle of amorphous alloy preparation is to rapidly cool the liquid metal at a rate greater than the critical cooling rate, hinder the crystallization process and form an amorphous state, preserve this thermodynamic metastable state and cool it below the glass transition temperature without The main preparation method is the quenching method, which first heats and melts the metal or alloy into a liquid state, and then makes them melt in 10 through various ways. 5 -10 8 The high-speed cooling of K / s causes the disordered structure of the liquid metal to be preserved and forms an amorphous state. The samples are in the form of sheets, ribbons or filaments with a thickness of several microns to tens of microns depending on the ...
