Air quantity adjusting apparatus for ageing furnace

Abstract

The invention provides an air quantity adjusting apparatus for an ageing furnace. The apparatus comprises a flow deflector, an air quantity adjusting plate, an adjusting plate, an adjusting plate support an adjusting rod and an adjusting nut, the flow deflector is hinged to the air quantity adjusting plate, the air quantity adjusting plate is connected with the adjusting plate support, the adjusting plate support is hinged to the adjusting rod, the adjusting rod is provided with the adjusting nut, and the adjusting rod is arranged in a socket. The reasonable air quantity adjustment of the temperature change of circulating hot air in all positions in the furnace is carried out by the air quantity adjusting apparatus for the ageing furnace, so the temperature in the furnace tends to consistency, and no deformation or oxidation is realized. Block making does not take the influences brought by thermal expansion into account, so the temperature field of all areas in the furnace can be effectively adjusted, thereby a problem of the unimproved aluminum product quality due to the long-term non-uniform temperature of the aluminum ageing furnace is well solved, and the defects of high defective index, large energy consumption and low material performance of an aluminum product are solved.

Description

technical field [0001] The invention relates to an air volume adjustment device, in particular to an air volume adjustment device for an aging furnace. Background technique [0002] For large and complex aluminum profiles, aluminum plates and aluminum products, the furnace temperature uniformity is effectively and conveniently adjusted during the aging heat treatment, thereby greatly improving the uniformity of the temperature field in the effective working area of ​​the furnace and improving the aging of aluminum materials. The pass rate of heat treatment has effectively improved the mechanical properties of all aspects of the material. It plays a very important role in the rapid development of my country's aluminum products industry. However, the traditional furnace temperature adjustment is to realize the multi-channel circulation of hot air by opening holes in the guide plate to achieve the effect of uniform temperature in the furnace. The actual effect is not ideal....
