Lindberg/MPH, Riverside, Mich., has shipped a gas-fired melting and holding furnace with a maximum temperature of 850°F for melting and holding up to 45,000 pounds of molten zinc for diecasting. The furnace incorporates seven immersion tubes, each with its own burner and ratio regulator control.
The system is rated at 2,300,000 BTU/hr. The furnace temperature controller includes a PID loop and LED display. The furnace includes an adjacent pump well with stainless steel weir to isolate dross. A splash shield was added to protect combustion piping from molten metal contact. The 180°F exhaust deflector improves efficiency and reduces noise.
“The design of this system facilitates energy-efficient melting and holding of the zinc and precise temperature control. Lindberg/MPH also supplied control and power wiring.” – Andrew Paul
This Lindberg/MPH furnace features individually operable spark ignited burners with flame rod flame safety. Each burner has its own gas/air ratio regulator assuring the correct air and gas mixture for dependable ignition and efficient combustion. On-off firing allows for a wide input range virtually eliminating temperature creep.
