A multi-element alloy co-infiltration furnace with full mixing and contact

Abstract

The invention discloses a fully-mixed contact multicomponent alloy co-permeation furnace. The fully-mixed contact multicomponent alloy co-permeation furnace comprises a rotary heating tank, a heating tank rotary vehicle, a left heating furnace and a right heating furnace. The left heating furnace and the right heating furnace are combined face to face to form a cylindrical heating cavity. The rotary heating tank and the cylindrical heating cavity are arranged coaxially. The rotary heating tank is arranged on the heating tank rotary vehicle and can move in the axial direction of the rotary heating tank and rotate around the axial direction of the rotary heating tank. The inner wall of the rotary heating tank is provided with four sets of fixing and clamping protrusions used for clamping and fixing four corners of the vertical section of bundled metal plates. By adopting the fully-mixed contact multicomponent alloy co-permeation furnace, on one hand, friction impact between the metal plates and the rotary heating tank is reduced, and on the other hand, the metal plates and the rotary heating tank are made to rotate synchronously, so that mixed contact between the metal plates and co-permeation agents is sufficient.

Description

technical field [0001] The invention relates to the technical field of multi-element alloy co-infiltration metal anti-corrosion treatment equipment, in particular to a fully mixed and contact multi-element alloy co-infiltration furnace. 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 sp...

AI Technical Summary

Problems solved by technology

When the metal sheet that needs multi-element alloy co-infiltration anti-corrosion treatment is rolled and heated in the co-infiltration furnace with the above structure for alloy co-infiltration treatment, the metal sheets will collide with each other, causing the metal sheet to deform or wear, so there is a certain In addition, when the co-infiltration furnace is rolling, the metal sheet in the co-infiltration furnace will roll in the co-infiltration furnace under the action of gravity, which will not only cause wear on the metal sheet and the inner wall of the co-infiltration furnace, but also affect the contact between the metal sheet and the co-infiltration furnace. The full contact and mixing of the multi-element alloy co-infiltration agent makes the alloy co-infiltration treatment of the metal sheet uneven, and there are weak positions for anti-corrosion
