Abstract
The utility model relates to a crystallizer copper tube for efficiently combining a plating layer and a substrate. The crystallizer copper tube comprises a copper substrate and a surface plating layer, wherein the inner surface of the copper substrate is provided with a sand blast treatment surface and is an uneven rough surface A; the inner surface of the plating layer is a rough surface B matched with the rough surface A; the concave-convex parts of the rough surface A and the rough surface B correspond to each other and extend into the opposite part; and the rigidity of the copper substrate close to the rough surface A is matched with that of the plating layer. The inner surface of a crystallizer is provided with a sand blast treatment surface, is an uneven rough surface and corresponds to the concave-convex part of the inner surface of the plating layer and extends to the opposite part, therefore, the binding force of the plating layer and the copper substrate can be improved, and the service life is prolonged. As the rigidity of the copper substrate close to the rough surface A is matched with that of the plating layer, the service life is prolonged.
Description
Technical field
The utility model relates to the manufacturing technology field of crystallizer, particularly relates to the efficient mating type crystallizer copper pipe of a kind of coating matrix.
Background technology
The plating exfoliation of existing crystallizer copper pipe internal surface is too fast, steel transportation amount is low, can not satisfy numerous clients' demand, presses for improvement, to improve its service life and steel transportation amount.
The utility model content
The purpose of the utility model is in order to address the above problem, to provide a kind of coating matrix efficient mating type crystallizer copper pipe.
The technical scheme of the utility model is: the efficient mating type crystallizer copper pipe of a kind of coating matrix, contain copper matrix and overlay coating, and the inner surface of copper matrix is a grit blasted surfaces, is rugged hair side A at the inner surface of copper matrix; The inner surface of described coating is and the hair side B of above-mentioned hair side A coupling that hair side A is corresponding each other with the convex-concave position of hair side B, and stretches into the other side each other.
Described copper matrix is near the hardness of hair side a-quadrant and the Hardness Match of coating.
The beneficial effect of the utility model
This internal surface of crystallizer is a grit blasted surfaces, and its surface is rugged hair side, and is corresponding each other with the convex-concave position of the inner surface of coating, and stretches into the other side each other, can improve the adhesion of coating and copper matrix, thereby increase the service life.
Copper matrix also is in order to prolong its service life near the hardness of hair side a-quadrant and the Hardness Match of coating.
Description of drawings
Fig. 1 is the sketch map of the efficient mating type crystallizer copper pipe of this coating matrix section;
Fig. 2 is the local structure for amplifying sketch map of Fig. 1.
The specific embodiment
1. matrixes among the figure, 2. coating.
The efficient mating type crystallizer copper pipe of a kind of coating matrix contains copper matrix and overlay coating among the figure, and the inner surface of copper matrix is a grit blasted surfaces, is rugged hair side A at the inner surface of copper matrix; The inner surface of described coating is and the hair side B of above-mentioned hair side A coupling that hair side A is corresponding each other with the convex-concave position of hair side B, and stretches into the other side each other.
Described copper matrix is near the hardness of hair side a-quadrant and the Hardness Match of coating.
The concrete implementation procedure of this coating structure:
The inner surface of crystallizer is thrown the back in essence and with quartz sand gas is carried out blasting treatment; Make its surface form scraggly hair side A; Plate coating then, in the process of above-mentioned blasting treatment, also removed the oxide layer of internal surface of crystallizer; And improved the hardness of internal surface of crystallizer, make its hardness and coating hardness coupling.
Claims (2)
