Aluminum Alloy Aging Furnace

Aging Furnace Introduction

Working principle of aging furnace

Aging furnace is a heat treatment equipment used for aging treatment of metal materials. Its working principle mainly includes temperature control, time control, and cooling system. After aging treatment, metal materials can undergo a series of changes, such as grain refinement, phase transformation, hardness increase, etc. The reason is that by maintaining at a specific temperature for a long time, the crystal structure inside the metal can develop and stabilize, thereby improving the mechanical properties and corrosion resistance of the material.

The aging furnace performs manual aging treatment on profiles to eliminate internal stress and improve mechanical strength.

Structure of the aging furnace

The equipment inside the aging furnace includes the furnace body, furnace door, and control system. The furnace body is composed of an inner lining, an outer crown, and an insulation layer; The furnace door is mainly composed of the door body, door leaf, furnace door sealing device, etc; The control system includes heating, temperature control, time control, furnace environment control, etc.

Application scope of aging furnace

The aging furnace is mainly suitable for the post-treatment process of aluminum alloys, including aviation, automotive, electronics, construction and other fields. Its main function is to improve the material properties of aluminum alloys, extend their service life, and is suitable for the production and processing of various aluminum alloy materials.

Operation steps of aging furnace

1. Load the billet onto the frame, push the frame into the furnace, and close the furnace door.

2. Turn on the heater and fan, check the temperature rise inside the furnace. The general temperature rise rate is 135 ℃ per hour, and keep a record.

3. When the temperature inside the furnace rises to 200 ℃, hold it for 2.5 hours.

4. Shutdown and discharge from the furnace

Precautions for operating Aluminum Alloy Aging Furnace

1. Suitable temperature and time parameters should be selected according to the process requirements to ensure the formation of the required alloy phase.

2. Before operation, check whether the electrical equipment, insulation layer, furnace door, etc. inside the furnace are normal.

3. Accurately control the heating speed inside the furnace to avoid heating too quickly or too slowly, which may cause unstable material properties.

During the heating and insulation process inside the furnace, good ventilation and heat dissipation should be maintained to avoid rapid temperature rise.

The aging furnace is a widely used equipment. When using it, one should fully grasp its principles, application scope, furnace equipment, and operating precautions, and follow the process requirements to achieve the best heat treatment effect.
