Abstract

[0002] Hot bell type bright annealing furnace can be widely used for bright annealing of non-ferrous metal copper, aluminum alloy and ferrous metal, carbon steel, silicon steel, alloy steel and other coils, coils, wires, etc. Its principle is a heat treatment process in which the metal material is heated to an appropriate temperature, maintained for a certain period of time, and then slowly cooled.
[0003] Common annealing processes include: recrystallization annealing, stress relief annealing, spheroidizing annealing, full annealing, etc. The purpose of annealing is to reduce the hardness of metal materials, improve plasticity, facilitate cutting or pressure processing, reduce residual stress, improve the homogenization of organization and composition, or prepare the organization for subsequent heat treatment.
[0004] The existing annealing furnaces are basically set up in the workshop. When the furnace bottom temperature is 100 degrees, the temperature is high in summer, forming a harsh high temperature environment. In order to ensure the working environment of the workshop, refrigeration is required. The increase in refrigeration costs leads to high production costs. In order to increase the load-bearing strength of the furnace bottom, the traditional annealing furnace uses 14-25mm metal plates as load-bearing vertical plates. The metal is welded to form a strong enough heat output. When the temperature in the furnace is 800 degrees, the metal surface will reach 100 degrees, which is very easy to cause heat loss.
