Bright annealing furnace is a metal heat treatment process, which means that the metal is slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at a suitable speed. The purpose is to reduce the hardness and improve the machinability; Eliminate residual stress, stabilize size, reduce deformation and crack tendency; Refine grain, adjust structure, eliminate structure defects.

The purpose of annealing is to soften materials or workpieces that have been cast, forged, welded or cut, improve plasticity and toughness, homogenize chemical composition, remove residual stress, or obtain desired physical properties.

There are many kinds of annealing processes depending on the purpose, such as recrystallization annealing, isothermal annealing, homogenization annealing, spheroidization annealing, stress removal annealing, recrystallization annealing, stabilization annealing, magnetic field annealing and so on.

The annealing furnace skeleton is made of various types of welded steel, the outer frame is made of channel steel as the main beam, the coaming plate is made of cold sheet, the platform is made of channel steel as the main beam, and the bottom plate and the front and rear end plates are made of middle plate.

How it Works:

The material to be annealed is placed in the inner cover with a protective atmosphere, and the material is raised and cooled according to the specified process curve by electric heating or gas or oil, so as to achieve the purpose of bright annealing. The furnace is currently the international advanced industrial production mainstream furnace type.

Applications:

Hood type bright annealing furnace can be widely used in non-ferrous copper, aluminum alloy and black metal, carbon steel, silicon steel, alloy steel and other coil, coil, wire and other bright annealing.

Heat treatment process in which metal materials are heated to the appropriate temperature, held for a certain time, and then slowly cooled. Common annealing processes are: recrystallization annealing, stress relief annealing, spheroidizing annealing, complete annealing and so on. The purpose of annealing is mainly to reduce the hardness of metal materials, improve plasticity, facilitate cutting or pressure processing, reduce residual stress, improve the homogenization of the organization and composition, or prepare the organization for the post-heat treatment.

The equipment can be widely used in non-ferrous copper, aluminum alloy and ferrous metal, carbon steel, silicon steel, alloy steel and other coil, coil, wire and other bright annealing. Strong convection bell type bright annealing furnace has the advantages of high production efficiency, good product quality, low energy consumption, no pollution, automatic operation, safety and reliability, and is one of the advanced heat treatment equipment internationally recognized.

Bright annealing furnace is a kind of annealing furnace, its working principle is: the material that needs to be annealed is placed in the inner cover with a protective atmosphere, and the material is raised and cooled by electric heating according to the specified process curve, so as to achieve the purpose of bright annealing. The furnace is currently the international advanced industrial production mainstream furnace type.

The main features of bright annealing furnace:

1. The whole annealing process of the material is placed in a protective atmosphere, the surface of the annealed workpiece is bright and no oxidation, and the steel surface is not decarburized.

2. Due to the strong convection circulation of the protective gas in the furnace, the furnace temperature is uniform, so that the temperature difference of the materials in the furnace is within ±5℃; It can effectively ensure the consistency of soft and hard annealed materials at any position, and facilitate deep processing of materials.

3. Adopt the quasi-continuous operation mode of double hearth heating and cooling, the furnace structure is scientific and reasonable, the energy saving effect is obvious, and the energy consumption per ton of steel is low; Single furnace capacity of 30 tons, high production efficiency.

4. The surface of the material treated by the furnace is bright, eliminating the pickling process, cleaning the working environment and eliminating acid pollution.

5. The whole set of equipment is controlled by microcomputer, with a high degree of automation, which can effectively ensure product quality and safe operation of equipment.

Scope of application of bright annealing furnace:

1. Black metal steel strip, steel wire, steel pipe parts and finished products bright annealing.

2. Non-ferrous copper strip, copper wire, copper pipe, copper rod middle and finished product bright annealing.

3. Standard parts, chains, mechanical parts and other parts bright annealing.
