Melting and Holding Furnace for Non-ferrous Metals

Electric Melting and Holding Furnace

• Type: crucible
• Shape: square, round
• Energy: electrical energy
• Capacity: 800kg (can be customized upon request)
• Melting rate: 180kg/h
• Process temperature: 630℃-750℃, cooperatively used with 630-800T die casting machine
• Structure: furnace casing, furnace lining, electric control system, crucible, round furnace wire with straight tube

The crucible inside the electric melting and holding furnace is uniformly heated by resistance radiation, allowing aluminum ingots to be placed in the crucible for melting and holding.

• External structure
  1) Barrel casing made of 4mm thick steel plate
  2) Crucible cover made of 25mm thick steel plate
  3) Bottom plate made of 8mm thick steel plate
  4) Cover made of 10mm thick steel plate
  5) Holding furnace cover (removable): outer layer is 6mm thick, inner layer is made of 60mm thick insulation material. Formed by one stamping, the holding furnace cover is manually lifted, and can be rotated at 360°
• Construction materials of furnace lining
  1) Three layers of high temperature insulation boards (Morgan-imported)
  2) Insulated cotton with the density of 260
  3) High-purity high-temperature insulating brick: mullite (Morgan-imported)
  4) Specially developed insulation materials
• Heating elements
  1) Resistance wire: quartz protecting tube that can withstand temperatures up to 1400℃, which is convenient for wire replacement
  2) Silicon carbide graphite protective cover
  3) Thermocouple: L-shaped stainless-steel thermocouple with an accuracy of ± 1 ℃

We are responsible for the transportation of equipment to the customers factory, transportation costs, installation and operation, and equipment training. We do not cover hoisting expenses incurred by unloading and placing equipment in place.

• The installation from the power grid wiring to national standard wire (at least 45mm) to be connected to the furnace is up to the buyer.
• The primary control cabinet power (380V, 50Hz, with additional circuit breaker) should be supplied by the buyer.
• The wiring from the control cabinet to the furnace is achieved using a high temperature resistant metal casing, which is supplied by us as long as it is within 4 meters.
• Notice on power distribution: Buyers should preinstall the power supply (over 220A) with air switches near the installation location with a control cabinet. A three-phase five-wire system with 35mm copper core, 4mm null line and 6mm earth wire is required.
• The electricity box must be connected to tap water for circulating cooling.
