Description of temperature range control
Aluminum annealing furnace is generally controlled below 600℃, the line speed depends on the size of the conductor section. Due to the low temperature-quenching temperature relative to aluminum, the amount of steam generated during cooling into the tank is small, and oxidation occurs from time to time. In order to increase the amount of steam and improve the density of steam, the temperature of the tank should not be too low, generally should be controlled at about 70℃; At the same time, the conductor sleeve into the end of the line must be fitted to the line pipe, in order to reduce the steam outlet section, relieve the passive inlet steam, so that the conductor in a stable preheating state, improve the softening effect.
Introduction to aluminum annealing furnace
Annealing furnace is a kind of metal heat treatment furnace, is to put the metal in a different annealing furnace slowly heating to a certain temperature, after holding heat for a period of time and then cooling with appropriate temperature, so as to make the workpiece or material soften, reduce hardness and improve plasticity and toughness, make the chemical composition uniform, achieve the expected physical performance.
Aluminum annealing furnace is mainly used for annealing large carbon steel and alloy steel parts. Tempering of surface quenching pieces; Stress relief annealing, aging and other heat treatment processes for welding pieces.
Heating methods include electric heating, fuel oil, gas, coal burning and hot air circulation. The annealing furnace framework is made of welded sections of steel.
Channel steel is used as the main beam for the outer frame, cold plate for the coaming, channel steel for the platform car as the main beam, and medium plate for the bottom plate and front and rear end plates.
Aluminum has good ductility (its ductility is second only to that of gold and silver) and can be made into aluminum foil thinner than 0.01 mm at 100 ℃ ~ 150 ℃.
