Double Regenerative Furnace Thermal Efficiency
The bottom of the regenerative trolley heating furnace is a movable trolley.Before heating, the trolley loads materials outside the furnace, the heating parts are put on the special pad iron, and then the trolley is pulled into the furnace by the traction mechanism for heating. After heating, the trolley is pulled out of the furnace by the traction mechanism for unloading, and then the heated workpiece is hoisted to the forging and pressing equipment for processing by the crane.
The national standard energy-saving cycle type furnace, super energy-saving structure, with composite fiber insulation, super lightweight high strength beads vacuum energy saving brick, exclusive rights to produce the brick off 20 ° inclined put on silk silk, collision brick front against the workpiece, automatic sealing car and oven door, integration of rail, without foundation installation, can be used on a level surface.
Scope of application:
Mainly used for high chromium, high manganese steel castings, gray cast iron, nodular cast iron, roll, steel ball, hammer head of crusher, wear-resistant lining plate quenching, annealing, aging and heat treatment of various mechanical parts.
1.Average gas consumption: 45-55m3/t.(natural gas)
2. Smoke extraction temperature ≤150℃
3. Furnace temperature uniformity ≤±10℃
4. The average life of imported components for directional valve is ≥ 200,000 times.
Regenerative combustion can improve the flame radiation intensity, enhance radiation heat transfer and increase furnace output.
