Lower noise emissions
Greater thermal efficiency

Furnace Construction

The furnace is a robust rectangular shaped unit with flat roof (other shapes also available), engineered for reverberatory heating of a molten metal charge. Our furnaces have a wide main door to facilitate both scrap loading and furnace cleaning. They are solidly built, particularly around the door surrounds to minimise warpage and loss of door sealing. Tilting of the furnace is actuated via twin hydraulic cylinders mounted between the tilting cradle and the stationary frame, with the pivot axis close to the pour point. The furnace is capable of tilting to allow the removal of all furnace contents.

Refractory Lining

This refractory lining comprises typically 230mm of 85% Alumina phosphate bonded refractories below the metal line backed up by insulating refractories for optimal wear characteristics.

Major also has the capability to re-engineer furnace refractory linings to accommodate new requirements such as siphoning systems or increased furnace capabilities.

Electrical Cabinet

A free-standing operator control panel of IP54 rating is provided to house the control equipment for the furnace. The PLC which is used to control the furnace operating parameters is typically housed in a separate control room or alternatively can be located in the main control cabinet.

Combustion System

The furnace typically has two nozzle mix burners with high turndown capacity and medium to high velocity flame to assist in good heat transfer. Burner controllers and over-temperature safety instruments are located in the operator control cubicle together with all necessary pushbuttons, indication lights, relays, etc. for the safe operation of the plant.

Air Pressure Control System

Furnace pressure is monitored by pressure transmitter and controlled by PLC PID loop. The furnace pressure is maintained at slightly positive to minimise ingress of cold air and hot egress and hence maximize fuel efficiency

Furnace Sizes

Major supplies an extensive range of reverberatory melting and holding furnaces with capacities ranging from 1 tonne to 80 tonnes. Others available on request.
