Clean Bottom Loading Furnace

Introduction:

Features and Benefits of Clean Bottom Loading Furnace:

Scheduled sintering function: Set sintering time according to requirements, automatically execute pre-stored sintering processes.
Automatic calibration of furnace table movement track origin to ensure safe and stable loading and unloading of materials every time.
One-button loading and unloading for simple and efficient operation.
Non-linear temperature compensation ensures accurate real-time temperature monitoring.
The rate of slow descent of the hearth(furnace table) at high temperatures is adjustable, maximizing both reliability and efficiency in experimental/production settings.
Furnace table embedded gas preheating system ensures high temperature field stability for material safety and experiment/production reliability.
High-purity Al2O3 fiber refractory insulation material provides superior insulation effect, effectively reducing equipment power consumption.
Heating elements are circularly distributed inside the furnace chamber, surrounding the quartz liner 360 degrees, improving temperature uniformity inside the furnace chamber.
High-purity quartz furnace hood, quartz liner, and high-sealing structure design ensure a high clean level of the working chamber.
