Method for forming film on roller surface through laser cladding

Abstract

The invention discloses a method for forming film on a roller surface through laser cladding, and belongs to the field of laser heat treatment. The method comprises the following steps: a) preparing a mixed adhesive according to the weight ratio being 1: (15 to 25) of shell-lac to ethanol, b) adding a wear-resistant medium into the adhesive, and stirring uniformly to form a coating liquid, wherein the weight ratio of the wear-resistant medium to the adhesive is 1: (4 to 6), c) cleaning the roller surface well, d) spraying the coating liquid onto the roller surface by a high-pressure spray gun, and e) carrying out laser heat treatment on a roller sprayed with the coating liquid. Through the adoption of the method, a film is formed on the roller surface through cladding, so that the service life of the roller can be remarkably prolonged, and the method has outstanding economic and environmental values.

Description

technical field [0001] The invention relates to a method for forming a film on the surface of a roll, in particular to a method for forming a film by laser cladding on the surface of a roll, and belongs to the field of laser heat treatment. Background technique [0002] The roll is an important equipment running part in the steel processing industry. In the steel processing industry, the roll is usually in direct contact with high temperature and heavy steel materials. This contact will cause wear, deformation and damage to the roll. Frequent replacement of the roll will not only It will lead to an increase in the cost of consumables, and it will also take up a large proportion of production time, which will have a greater impact on the production and benefits of rolling steel. In today's fierce competition after the marketization of the steel industry, the impact of rolling steel wear and replacement is even more serious. In order to stand out, all enterprises are looking f...

[0002] The roll is an important equipment running part in the steel processing industry. In the steel processing industry, the roll is usually in direct contact with high temperature and heavy steel materials. This contact will cause wear, deformation and damage to the roll. Frequent replacement of the roll will not only It will lead to an increase in the cost of consumables, and it will also take up a large proportion of production time, which will have a greater impact on the production and benefits of rolling steel. In today's fierce competition after the marketization of the steel industry, the impact of rolling steel wear and replacement is even more serious. In order to stand out, all enterprises are looking for new ways of scientific and technological progress and lean management. Rolls with longer life can effectively reduce their consumption speed and replacement frequency. High energy density can make its surface form a contact layer with superior performance compared with the background material, but this treatment method is limited to the phase transformation of the roll itself and the wear-resistant layer formed by tissue reconstruction, and cannot adapt to the modern steel industry. The demand for economical and efficient operation, the industry urgently needs a more effective way to improve the life of the roll
