Equipment Description
The furnace comprises a refractory lined cylinder, swing aside charge door, rear mounted burner and flue, rotary cradle and roller bearings, stationary floor mounted support, fixed fume hood and control cabinet.
Furnace Construction
Charging occurs through an opening in the front of the furnace. The liquid metal discharge occurs through a pour spout mounted in the mid section of the main refractory lined cylinder. When the charge door is closed the front section is a close fit to the main rotating body thus leakage of the flue gases during normal operation is minimised.
Refractory Lining
The refractory lining is of a high quality, abrasion resistant brick and castable, backed up with high density insulation board. The charge door is lined with a dense hot face castable and an insulating backup up.
Furnace Waste Gas Ducting
A fixed flue canopy is directly mounted above the charge door. The flue and canopy for this type of furnace is normally supplied by the ventilation contractor. This system requires an induced exhaust fan downstream of our battery limit.
Electrical Cabinet
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.
Combustion System
The fuel 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.
Safety
Floor mounted personnel protection guarding 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 around the mechanism pinch points, and beside the furnace on each side, protecting personnel from the door opening.
