Compound tube plate

Abstract

The invention provides a compound tube plate. A groove is formed on a part to be protected on a base material tube plate; a metal compound material is poured into the groove; a cover plate is connected to the groove in a sealing mode; another material is directly poured into the groove formed on the tube plate, so the thickness of the material of the compound layer can be controlled easily; the metal compound material and the base material tube plate are mutually melted, so the strength of the base material tube plate is enhanced; moreover, the compound tube plate has anti-corrosion performance; and pouring can be performed at any position of the tube plate, materials are saved, metal pollution is reduced, and resources are effectively saved.

Description

technical field [0001] The invention relates to a composite tube plate. Background technique [0002] At present, the molding process of composite materials mostly adopts explosive molding or welding surfacing method, electroplating method, etc. [0003] Explosion molding requires a relatively safe and relatively closed special site. The explosion requires a large area of ​​action. There are gaps in the edge parts that have not been affected by the explosion. They must be cut before they can be used, resulting in increased costs. Since the surfacing method is carried out with a large current, the welding is easy to cause deformation of the tube plate. To avoid deformation, the thickness of the plate must be increased, and mechanical processing must be performed after surfacing, so the cost increases and the working cycle is long. Electroplating composite tube sheet materials are technically difficult, long in cycle and high in cost. Contents of the invention [0004] The...

[0003] Explosion molding requires a relatively safe and relatively closed special site. The explosion requires a large area of ​​action. There are gaps in the edge parts that are not affected by the explosion and must be cut before use, resulting in increased costs.

The surfacing welding method is carried out with a large current, and the welding is easy to cause deformation of the tube plate. In order to avoid deformation, the thickness of the plate must be increased, and mechanical processing must be carried out after surfacing welding, so the cost increases and the working cycle is long.

The technical level of electroplated composite tube sheet material is difficult, the cycle is long, and the cost is high
