General Melting Furnace Design Features
- Heavy duty casing construction to withstand thermal and mechanical stresses.
- Expansion allowance and compensation in furnace design.
- Hydraulic or Electro Mechanical door lifting with synchronisation shaft to ensure uniform lift.
- Vertical or inclined doors.
- Static furnace or tilting (side or rear) furnace designs.
- Tilt cylinders integrated either at front of furnace, at floor level down side of furnace or underneath furnace in basement.
- Positive pneumatic door clamping and sealing systems.
- Long lasting refractory block, cast steel or water cooled door surrounds.
- Furnace chamber exhaust ducting systems and stacks to atmosphere
- Door fume extraction hoods
- Automatic pressure control regulation using an actuated ‘mechanical damper’
- Pneumatically operated automated bath thermocouple to insertion and retraction system.
- High efficiency regenerative burners, hot air recuperation or cold air burner systems.
- Gas fired, Oil fired or electrical heat input systems
- Electronic Fuel/Air ratio control or Thyristor control on heating elements
- Manual or automatic metal pouring operation to suit specific casting requirements
- Durable refractory linings in monolithic, brick or pre-cast blocks.
- Molten metal receiving wells with hot metal crucible tilting mechanisms for furnace filling.
- PC/PLC based control systems with human/machine interface giving ‘Set point’ furnace control.
- SCADA control systems.
- Continuous emission monitoring, data logging and trend analysis for environmental legislation.
