DROP BOTTOM FURNACES FOR SOLUTION HEAT TREATMENT

Drop bottom furnaces used for T4 / T6 heat treatment of aluminum profile materails, the parts are automatically loaded to the baskets or manually. The basket is brought to the loading position of the furnace, with the automatic loading car. Baskets are moved to the furnace chamber with pneumatic elevator. After the door is closed and the sealing with the pressing system is achieved, the parts to be heated are dropped to the quench tank in about 6 seconds by opening the bottom doors of the furnace according to the determined heat treatment program (process). The liquid in the quench tank is preheated to the desired temperature by means of resistance and set, so that the liquid remains stable at the specified temperature while in the material. The liquid in the tank is detected by level sensors and filled with automatic pumps. When the cooling process is completed, the basket is automatically lifted and put down to the waiting area of the transfer car. All these operations can be done automatically or semi automatically if desired. All temperatures during the heating process are recorded with the recorders.
