PRODUCT PARAMETERS
Description
1000°C Pit-Type Heat Treatment Furnace
The 1000°C pit-type heat treatment furnace is an industrial heat treatment unit that integrates vacuum capabilities, atmosphere protection, and high-precision temperature control. It features an independent dual-zone (top and bottom) temperature control structure, a high-temperature alloy resistance wire heating system, and an intelligent touchscreen control platform, enabling precise temperature regulation, uniform heating, and automated operation. Equipped with vacuum and atmosphere control systems, the furnace supports the introduction of various gases—such as hydrogen, nitrogen, argon, and oxygen—to provide a stable and reliable processing environment for material heat treatment.
Product Features
- Independent Temperature Control for Upper and Lower Zones
The equipment features two independently controlled temperature zones, allowing for separate temperature parameter settings. The temperature uniformity within the furnace chamber is ±1°C (depending on the heating chamber dimensions), ensuring consistent temperature distribution across the upper and lower zones.
- 310S Stainless Steel Inner Chamber
The inner chamber is constructed from 310S stainless steel, offering excellent high-temperature performance as well as superior oxidation and corrosion resistance. Chamber dimensions: 600mm (diameter) × 300mm (height).
- Dual-Mode Operation Vacuum and Controlled Atmosphere
Achieves a vacuum level of -0.1 MPa and supports the introduction of various gases, such as hydrogen, nitrogen, argon, and oxygen. Equipped with two gas inlets (flow rate controlled by rotameters) and one gas outlet (featuring an automatic pressure relief valve); the vacuum system utilizes a mechanical pump.
- Electric Top-Opening Door with Manual Lateral Shift for Convenient Operation
The furnace door opens electrically upwards and can be shifted laterally by hand, ensuring flexible and convenient operation. Silicone rubber seals (rated for 260°C–350°C) provide excellent sealing performance, maintaining stable internal pressure under both vacuum and controlled atmosphere conditions.
- Centralized Control via 7-Inch Touchscreen with Data Traceability
Equipped with a 7-inch true-color touchscreen, the system supports functions such as temperature program setting, historical curve plotting, data reporting, and real-time display of temperature, voltage, current, and vacuum levels.
