Center Pivot Tilting Melters

Gas Fired Melting Furnaces-maximum temperature 2400 deg F.  Will run on natural gas or propane-adjust the gas air mixture accordingly (no orifice to change).

MODELS T-160, T-301 and T-80

T-80 pictured above

A most economical tilting furnace in sizes ideal for the small foundry, vocational or educational facility, and the precious metal melter or reclaimer. These center pivot models pivot at their center of gravity for easy tilting by a worm/worm gear drive. The manual tilt is operated with a hand wheel.  The worm gear tilting feature eliminates the possibility of accidentally dropping the furnace from the tilting position. Precision engineered gears, operating in an oil-tight gear box, provide years of smooth operation. The furnaces come equipped with a swing away refractory cover which can be locked in the closed position.

FLEXIBILITY, VERSATILITY, and ECONOMY

MIFCO manufactures some of the most versatile melting furnaces available. The wide temperature range will allow the melting of most non-ferrous metals used in casting and some grey iron up to class 25 or 30. All of these units have a temperature range of 1200° to 2400° F and are designed to melt as rapidly as possible. In the school shop or industrial foundry, these units have an immediate and profitable application. They cover nearly the entire range of modern melting needs. The initial investment for this type of industrial equipment is nominal and the maintenance is held to an absolute minimum due to the rugged construction and high quality of the furnace lining.

RUGGED, WELDED STEEL CONSTRUCTION

The outer shells of MIFCO furnaces are heavy gauge steel, reinforced where necessary, with rolled steel bars and welded throughout. The rugged construction conforms to the highest industrial standards. The lid support rings are also constructed of heavy gauge rolled steel bars. The furnace lids are recessed in sectional cast chrome-iron protection plates. The lid derrick is simple in design and sturdily constructed with a detachable handle to prevent overheating. Structural steel legs provide air circulation beneath the unit to prevent overheating of the foundry floor. The low operating height provides greater convenience for charging of the crucible. Each unit is provided with an overflow and drain hole in the base of the furnace.

SECTIONAL REFRACTORY LINING

Super-duty high alumina, hand-made, air rammed, pre-fired refractory shapes are used in the lining and dome shaped lids of all MIFCO High Speed Melters. The rapid melting schedules and capacity to melt grey iron make it mandatory that we use the best refractory material available to insure long life of the furnace lining. Super-duty high alumina can withstand the drastic temperature changes due to rapid heating and can operate at temperatures in excess of 3000° F without spalling or deterioration. Sectional linings facilitate movement during heating to prevent thermal cracking and deterioration of the lining and lid. Field replacement of the linings and lids is rapid and easy. Refractory relining kits are available for all MIFCO furnaces.

The crucible in the T80 furnace is held in place by 2 crucible support bricks.
The crucible in the T160 and the T301 furnace is held in place by a pour spout brick shown below.

HIGH TEMPERATURE INSULATION

High temperature castable insulation between the steel shell and the combustion chamber lining combine high strength and excellent insulating properties. This provides faster heating, lower heat loss and greater burner efficiency.

BURNER SYSTEM

The MIFCO gas-air mixer will utilize any type of fuel gas – natural, bottled or tank. The venturi design of the aspirator mixer develops a slight suction against the main gas line, eliminating the need for check valves. The standard mixer system is a manual two-valve control which permits the operator to set any type of flame or atmospheric characteristics desired. Both the gas and air valves are conveniently located. The type of fuel gas can be changed as desired without having to change an orifice or jet on the mixer. Each furnace is shipped complete with a blower. It is only necessary to make gas and electrical connections and the furnace is ready to operate.

COMBUSTION SAFEGUARD SYSTEM

Combustion safeguard system are standard equipment on all MIFCO furnaces. The burner control is an industrial type, electronic unit activated by a flame sensor that detects the ultra violet spectrum of the burner flame. Response to a flame failure of any kind is within 2 to 4 seconds and flame monitoring is continuous. The burner system is ignited by a timed electronic spark. In the event of a flame failure, reset of the burner control is manual.

All MIFCO gas fired tilt furnaces manufactured  in the year 2015 and later meet the minimum NFPA 86 guidelines (applies to burner systems over 150,000 BTU/HR):

• Two valves required on pilot and main burners
• Visual indication of valve position required for burners above 150,000 BTU/HR
• High and low gas pressure switches required
• Burners above 400,000 BTU/HR require visual indication and proof of closure

We recommend that the customer install a pressure gauge and regulator on their incoming line.  We DO NOT provide these.
