Digital display

Measuring temperature, setting temperature double display

Control features

Control system modular structure, long life design of key components of the equipment, simple and reliable process, good stability and high precision.

Air cooling system

The fan impeller is mounted directly on the bottom of the double furnace shell and assembled with the control system. When the sintering furnace is heated, air cooling can reduce the surface temperature of the furnace shell and protect the heat of the electric appliance, and the personnel operation is safer and the efficiency is improved.

Refractory

The lining is made of high-quality high-purity alumina fiber, vacuum-formed fiber-reinforced light-weight board material, light-weight hollow-balloon alumina board, high temperature, low heat storage, resistance to rapid heat and cold, no cracks, no slag, good insulation performance ( The energy saving effect is more than 80% of the old electric furnace). The double-furnace structure patent is a patented feature that not only heats up quickly, but also has durability and long-term use without collapse.

Insulation Materials

High-quality alumina multi-fiber insulation material, insulation layer is 150mm.

shell

The furnace shell is made of steel plate and profile welded, and the outer casing is equipped with a removable protective plate. The protective plate is electrostatically sprayed and painted. Fine workmanship and beautiful appearance.

Furnace structure

Double-layer furnace shell structure, air-cooled circulation, reducing the temperature of the shell. The surface temperature of the shell is < 60 degrees.

The surface of the inner furnace is coated with a high-temperature alumina coating to increase the heating efficiency of the equipment and to extend the life of the instrument.

Energy saving performance

Light weight, fast heating, energy saving of more than 50%, saving time and effort.

Random spare parts
