A multi-component alloy co-infiltration treatment method with sufficient mixing and contact

Abstract

The invention discloses a sufficiently mixing and contacting complex alloy co-permeation treatment method, which comprises the following steps of bundling plate materials; laminating the metal plate materials requiring complex alloy co-permeation treatment into a stack with the similar height and width; laying a layer of co-permeation agents between the adjacent metal plate materials; then, packing the laminated and stacked metal plate materials into a bundle by a U-shaped rod provided with screw threads at the two ends; performing fixation in a furnace; and feeding the packed and bundled metal plate materials into a rotating heating tank of a co-permeation furnace, wherein the inner wall of the rotating heating tank is provided with four groups of fixed clamping bulges; each group of fixed clamping bulges consists of a horizontal position limiting convex block and a vertical position limiting convex block; and the four groups of fixed clamping bulges respectively clamp and fix four corners on the vertical cross section of the packed and bundled metal plate materials. The treatment method has the advantages that on one hand, the friction collision between the metal plate materials and the rotating heating tank is reduced; and on the other hand, the metal plate materials and the rotating heating tank synchronously rotate, so that the contact and the mixing of the metal plate materials and the co-permeation agents are sufficient.

Description

technical field [0001] The invention relates to the technical field of multi-element alloy co-infiltration metal anticorrosion treatment, in particular to a fully mixed and contact multi-element alloy co-infiltration treatment method. Background technique [0002] The embedded parts of bridges with reinforced concrete structure are prone to corrosion and damage the concrete structure of the bridge due to long-term exposure to various corrosion-causing factors such as freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction; especially due to humidity The effect of carbon dioxide, temperature and carbon dioxide will cause the carbonization of concrete, and the effect of corrosive media such as oxygen, sulfur dioxide and chlorine will further aggravate the corrosion of bridge embedded parts and the damage of concrete structure. Traditional anti-corrosion processes such as electro-galvanizing, electro-cadmium plating, hot-dip galvanizing, thermal spra...

Problems solved by technology

This is a pre-embedded plate for anti-fall beams commonly used in bridge infrastructure. When the fixed plate of the anti-fall beam pre-embedded plate is rolled and heated in the co-infiltration furnace for alloy co-infiltration treatment, the fixed plates will collide with each other so that The fixed plate is deformed or worn, so there is a certain defective rate; in addition, when the co-infiltration furnace rolls, the fixed plate in the co-infiltration furnace will roll in the co-infiltration furnace under the action of gravity, which will not only cause the fixed plate and co-infiltration The wear of the inner wall of the furnace will also affect the full contact and mixing of the fixed plate and the multi-element alloy co-infiltration agent, so that the alloy co-infiltration treatment of the fixed plate will be uneven, and there will be weak anti-corrosion positions
