Arc & Stress Relieving Furnace

MG make Electric Arc Furnace is a squat, cylindrical vessel made of heavy steel plates. It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof. The shell sits on a hydraulically operated rocker that tilts the furnace forward for tapping and backward for slag removal. The bottom—i.e., the hearth—is lined with tar-bonded magnesite bricks and has on one side a slightly inclined taphole and a spout, an oval hearth and a vertical taphole. With this latter arrangement, a furnace needs be tilted only 10° for tapping, producing a tight and short tap stream that decreases heat loss and reoxidation of the liquid steel. Before charging, the vertical taphole is closed from the outside by a movable bottom plate and is filled with refractory sand.

The major benefits for MG make EAF are -

• Compact design with minimum space requirements
• User friendly for ease of operation and maintenance.
• Low refractory wear due to small pitch circle diameter
• EAF can be supplied for min. of 2 MT & LRF Can be supplied for min. of 15 MT of steel refining and upwards.
• Hydraulic electrode movement & control system
• Furnace operations and control are automated with PLC and computer based Human Interface which are very friendly to operate and maintain.

• Production Capacity: 2000 kg to 50000kg
