Product Description

Product Description

The GWDL-JR series 1000°C pit-type electric furnace is designed for high-precision heat treatment, sintering, and materials research involving ceramics, metallurgy, electronics, refractory materials, new materials, and high-performance alloys. The furnace body and lid are constructed using vacuum-formed high-purity alumina insulation with low thermal mass, paired with a durable refractory brick base for enhanced load-bearing.

Featuring a hydraulic lifting lid for easy access and a three-zone independent temperature control system, the furnace minimizes vertical temperature deviations, ensuring superior uniformity for tall workpieces. The ring-shaped Mo-alloy heating elements are mechanically protected by mullite shields to prevent contact damage during loading/unloading, effectively reducing wear and prolonging service life.

Equipped with an intelligent touchscreen controller, the system supports 50 programmable steps, multi-curve storage, real-time power monitoring, and built-in safety functions such as overcurrent, overtemperature, and dual-loop protection.

Key Design Advantage
Mechanical Protection Panels: Mullite protection boards shield heating elements from direct contact and accidental impact, reducing risk of breakage during loading/unloading.
Hydraulic Lid Lifting: Enables easy and safe vertical access to the furnace chamber, reducing labor intensity and improving operational safety.
Three-Zone Temperature Control: Independent control of top, middle, and bottom heating zones effectively reduces vertical thermal gradients for enhanced process precision.

Standard Equipment
Maximum Temperature (Tmax)	1200℃ / 1400℃ / 1800℃
Thermocouple Type	K / S / B (depending on temperature level)
Heating Elements	High-temperature alloy resistance wire / SiC/ MoSi2
Heating Zones	Installed vertically on both sides of the furnace chamber. (Optional expansion to multi-zone heating)

Temperature Uniformity	Within ±5℃ (depending on chamber size)
Heating Rate	Adjustable: 1℃/h to 40℃/min (non-linear control)
Furnace Lining	The furnace lining is constructed from imported vacuum-formed high-purity alumina fiber lightweight boards. High-contact areas such as the furnace base are reinforced with high-purity alumina hollow ball plates, providing high temperature resistance, low thermal mass, excellent thermal shock resistance, no cracking, no spalling, and superior insulation (over 80% energy savings compared to traditional designs).
Insulation System	A three-layer insulation system is employed, consisting of high-alumina wool, alumina fiber board, and imported fiber board. Critical contact areas such as the furnace opening use shaped high-purity alumina lightweight components to enhance durability and energy efficiency.
Shell Construction	Dual-layer ventilated carbon steel shell; surface temperature ≤45℃; coated in RAL 7035
