aluminum billet heating treatment Homogenizing Furnace
The lining part of the furnace body adopts a full-fiber energy-saving structure, which saves energy by about 40% compared with the brick-type furnace. It is made of high-quality long-fiber thorn blankets as raw materials and is made with special equipment to achieve a good heat storage effect. It is directly fixed on the stainless steel anchor round nail of the steel plate of the furnace shell. The furnace mouth and the parts that are easy to collide are made of refractory bricks. Compared with other products, the advantages are low thermal conductivity, low heat capacity, excellent corrosion performance, thermal shock resistance and thermal insulation, which improves the high temperature strength of the fiber. The all-silicic acid refractory fiber material with good thermal insulation performance and light weight is specially processed, which can effectively prevent the heat in the furnace from being conducted and dissipated, and has excellent energy-saving effect. The furnace door is also made of this material.
The homogenizing furnace uses solid-state relays as heating control elements for the temperature in the furnace. In order to ensure the uniformity of the temperature in the homogenizing furnace, the hot air circulation system of the homogenizing furnace adopts several fans with large air volume to be used in parallel. Very small temperature difference.
Working principle: The equipment is a trolley structure. The workpiece to be processed is placed on the trolley. After the workpiece is loaded, the trolley is driven into the furnace by the traction motor of the trolley, and the furnace is closed. During the operation of the equipment, the heat emitted by the heating elements installed on both sides of the furnace will blow the hot air to the workpiece through the circulating fan installed on the top of the furnace body and the inner channel of the furnace, and then return from the suction port of the circulating fan to form a hot air circulation. Ensures temperature uniformity in the furnace. When the workpiece reaches the process temperature, the furnace door is opened, the trolley is driven out of the furnace, the processed workpiece is unloaded by the crane, and a new workpiece is installed for the next furnace production.

Product information
The homogenizing furnace unit consists of one 20t gas homogenizing furnace, one 20t cooling chamber & one 20t composite charging car. It’s for homogenizing aluminium billets to eliminate the unevenness chemical composition and internal organization of the billets. Then the billets are cooled at a controlled manner in the cooling chamber to improve metal processing performance for later extrusion or other processes.
Technological Process:
1. Material Storage: the billets are placed on the tray of the material loading platform by the crane;
2. Material Loading into Furnace: the composite charging car carries the tray from the platform and to the furnace doorway, while at the same time the furnace door is lifted to position and it’s locked safely; charging car then enters the furnace and its lifting device lowers to place the tray on the brackets, the car retreats, and then furnace door is closed and sealed;
3. Homogenize: After the furnace door is closed, the furnace has the temperature rising & maintaining rapidly automatically according to the set homogenizing technological curve. Temperature difference of each spot inside the furnace is less than ±5℃ during the process of temperature rising.When furnace air temperature reaches setting point, according to processing requirement, the circulation blower switches speed automatically to ensure furnace temperature’s uniformity;
When it reaches temperature maintaining stage, number of combustors working or fuel supply quantity is adjusted automatically to meet the requirement for furnace temperature’s uniformity.
4. Material Moving Out of the Furnace: When homogenizing process is finished, charging car moves to the furnace doorway, the furnace door is lifted to position and locked safely, charging car enters the furnace and carries out the tray and sends it to cooling chamber.
5. Cooling Process: charging car moves to the gate of the cooling chamber, chamber door is opened, charging car then enters the chamber, places the heated tray onto the brackets and retreats, the door is closed, rapid cooling system is started to cool down the billets. When the billets are cooled to the required temperature, air cool is adopted, that is the air from chamber outside flows in via blower for cooling the billets, the hot air is extracted from blower;
6. Material Unloading: After the cooling process, charging car enters the chamber to carry out the tray and waits for unloading, when unloading is done, the crane collects the billets, and the next circle starts.
