TECHNICAL FIELD
[0001] The utility model mainly relates to the technical field of cover type bright annealing furnace, concretely relates to a cover type bright annealing furnace with good heat preservation function. BACKGROUND
[0002] The hot bell type bright annealing furnace can be widely used for bright annealing of copper, aluminum alloy, black metal, plain carbon steel, silicon steel, alloy steel and the like, and can be used for bright annealing of strip, pipe and wire rod. The principle is that the metal material is heated to a proper temperature, kept for a certain time, and then slowly cooled.
[0003] Common annealing processes include recrystallization annealing, stress relief annealing, spheroidizing annealing, and full annealing. The purpose of annealing is to reduce the hardness of the metal material, improve the plasticity, facilitate cutting or pressure processing, reduce residual stress, improve the uniformity of the structure and composition, or prepare the structure for subsequent heat treatment.
[0004] The existing annealing furnace is basically arranged in a workshop. When the temperature of the furnace bottom is 100 degrees, and the temperature is high in summer, a poor high-temperature environment is formed. In order to ensure the working environment of the workshop, refrigeration cooling is needed. The increase of refrigeration cost increases the production cost of products. In order to increase the bearing strength of the furnace bottom, the traditional annealing furnace uses 14-25mm metal plate to make the bearing vertical plate, and the metal is welded into shape. Although the strength is enough, the heat dissipation is also increased. When the temperature in the furnace is 800 degrees, the metal surface part will reach 100 degrees, which is easy to cause heat loss. UTILITY MODEL CONTENTS
