Bottom Loading Furnace

High Temperature Bottom Loading Furnace up to 1700℃

This bottom loading furnace is very convenient to load and unload, and the heating elements are distributed around the furnace evenly so that the temperature is uniform. The Max. temperature is 1700°C.

The bottom lifting furnace platform is located under the electric furnace, which can be lifted manually or automatically. The furnace can also be made into a Bogie Hearth Furnace, which is convenient to operate.

The electric bottom loading furnace is widely used for battery materials, electronic ceramics, magnetic materials, non-ferrous metals, chemical raw materials, etc. Meanwhile, it is suitable for sapphire wafer annealing and zirconia sensor heating treatment in scientific labs or universities, etc.

Bottom Loading Furnace Features:

  • Max temperature:
    1200℃ (HRE Fe-Cr-Al-Mo wire)
    1400℃ (SiC Heater)
    1700℃ (MoSi2 Heater)
  • Large loading capacity, easy operation, and high efficiency,
  • Suitable for small workpiece high-temperature heating treatment.
  • Four-sided heating, excellent furnace temperature uniformity (< ±5 °C).
  • The furnace materials use the vacuum-formed high-purity alumina fiber materials, which can bear the high temperature, excellent heat preservation performance.
  • Digital intelligent temperature controller with PID control, 51-segments
  • programmable temperature rise curve.
  • Electrostatic spray shell, resistant to corrosion and acid.
  • Increase efficiency by built a double rail trolley.
