Furnaces with accessories are designed for heating of forgings and castings made of aluminium alloys up to 600 °C and following quenching.
Furnaces are designed with a view to the specifi c requirements that should be provided for this type of heat processing. Primarily, it the temperature accurateness, intensive air flow in the working area and fast dip of the charge in the quenching medium where hardening is required.
Furnaces are fi tted with fans. The air forced circulation promotes even distribution of the temperature and a faster transfer of heat to the charge. According to the required direction of flow (vertical, horizontal), fans are fitted on the ceiling or on the sidewalls. A system of suction and draught fl aps provide for the furnace atmosphere exchange.
A fan may be added to the system to increase the intensity of the air exchange. On models with electrical heating, the furnace power input is switched by contactors while on larger power it is contactless, by means of solid-state relays or thyristor units. The temperature in the furnace is measured by thermocouples or thermostats and it is controlled by digital microprocessor controllers with the control set to value, a simple ramp function or fully programmable controllers. With larger units, control is possible by a PC-based industrial automatic control unit. Dimensions, power input and design are assessed individually according to specifi c processes, the charge weight and temperature curves.
