The furnace comprises a refractory lined rotating cylinder, swing aside charge door with integral burner and flue, tilt cradle, stationary floor mounted supports, tilting fume hood and control cabinet.
Benefits over Conventional Non-Tilting Rotary Furnaces
Faster, safer metal & slag tapping practices
Lower noise emissions
Reduced cycle times
Greater thermal efficiency
Reduced flux requirements
Quicker charging sequences
Reduced labour requirements
Charging and discharging are both achieved through an opening in the front of the furnace. The charge/discharge door houses the burner and flue which allows the flue gases to attain a double pass. Opening is actuated via a hydraulic actuator which moves about a pivot located to the side. This requires only one position for flexing of the gas, air and electrical cables and results in the furnace door moving to one side with a total rotational travel of 180 degrees.
Furnace Waste Gas Ducting
The flue canopy is directly mounted on to the tilt cradle with the duct terminating on the pivot axis so that fumes may continue to be extracted via a rotating joint throughout the full range of tilt. The flue duct battery limit is a stationary flange at the rotating joint. This system requires an induced exhaust fan downstream of our battery limit.
The electrical control cabinet has an environmental rating of IP55 and is engineered to be mounted either adjacent to or remotely from the furnace. The electrical battery limit is the cabinet mounted electrical isolation device.
The gas train components have an environmental rating of IP54. The combustion air blower is fitted with noise attenuation on the inlet to reduce noise levels to 83 dBa at 1 metre.
Oxygen / Fuel Combustion
Major’s oxygen enriched combustion system provides customers with an advanced method of processing metals. Our proprietary PLC program provides for tailored cycle parameters to optimise metal recoveries.
Floor mounted personnel protection guard rails can be provided which are engineered to the Australian Standard and are adjacent to moving parts outside frame support and around hot areas. Guards are provided across the driven end near the rotating motor, and beside the furnace on each side, protecting personnel from the door opening.
