Precision T5 Treatment Line Installed
LAC has successfully completed installation of the gas furnace SVKP 20000/03. This is a T5 furnace used for the artificial ageing of aluminium pistons. The 20,000L furnace is for a max. temperature of 300 °C and a working temperature of 250°C, and is designed to meet the customer’s extremely strict temperature uniformity requirements. The temperature distribution in the fully-loaded furnace in stable state is ± 3°C, and it is designed to  guarantee a heating rate inside of the piston from 20 ° to 230° in a maximum of 150 min?
 
The SVKP is a gas heated bogie hearth furnace with total input power of 800kW (200kW per heating unit). Its forced air circulation system and state of the art insulation ensures the required ± 3°C temperature uniformity. The furnace’s heating system is divided in to four heating zones each with its own automatically operated exhaust flap. Fan units with gas burners are located in each zone, on the top of the furnace. The temperature in individual zones is scanned by a type „K“ thermocouples and every zone is equipped with an independent safety limit unit to protect the furnace from overheating
 
The fans remove the air from the working chamber and blow it through the side walls back into the chamber. The furnace bogie runs on rails embedded in the floor, and the door is automatically operated and opens upwards. The Siemens PLC SIMATIC S7-1200 control system with TP700 operator touch panel synchronises movements of the door and bogie as well as handles furnace regulation. Temperature and heating times are set up on the touch screen and movements of the furnace bogie are signalised optically and acoustically.
