Abstract

The continuous annealing process of blown aluminum plate belongs to the field of metal heat treating technology. The annealing apparatus includes one furnace body, one heater, one temperature controller and one circulating and suspending material conveyer penetrating the top of furnace cavity, and is heated with natural gas. The process includes heating, feeding, temperature setting, rotation speed setting and other technological procedures. The process has low power consumption, stable annealing quality, short production period, high safety and high operation efficiency.

Description

Technical field [0001] The invention relates to the technical field of metal heat treatment. Specifically, it relates to continuous annealing methods for inflated aluminum sheets. Background technique [0002] The inflatable aluminum plate must be annealed before inflation to eliminate the internal stress of the material caused by the various processing steps before the aluminum plate is inflated, such as hot rolling, cold rolling, etc., to ensure that the material has sufficient plasticity during inflation. At present, the annealing method of the inflatable aluminum plate is commonly used for annealing in an ordinary box-type furnace, using electric heating, and by placing a rated number of aluminum plates in the furnace at one time, the annealing time is more than 12 hours, and the required value of annealing hardness is reached. This annealing method It is an intermittent production method. The annealing of inflation aluminum sheets is generally a large-scale production ...
