High-Temperature Aging Detection Equipment with Multi-Zone Heating and Forced Hot Air Circulation

Equipment Description

I. Heating and Temperature Control System
1. Heating Elements
Silicon Carbon Rods/Heating Tubes: Utilize high-temperature-resistant silicon carbon rods or honeycomb stainless steel heating tubes, enabling rapid temperature increases (0–30°C/min) up to 1600°C and offering a long service life.
Multi-Zone Heating: Heating elements are symmetrically arranged on both sides of the furnace, combined with a forced hot air circulation system to ensure temperature uniformity (no-load temperature difference ≤ ±2°C).
2. Control System
Temperature Control Module: Integrated with PLC and PID algorithms, supports multi-stage programmable temperature control (50 programmable steps), with a temperature accuracy of ±0.5°C and real-time display of temperature curves and operating status.
Safety Protection: Automatic over-temperature shutdown, leakage protection, heating element overload protection, and fault alarms ensure stable equipment operation.

III. Operation and Maintenance Specifications
1. Usage Procedure
Preheating: For the first use, run the furnace unloaded for one hour (at 300°C) to remove moisture and impurities.
Loading: Place the sample in a high-temperature resistant crucible or tray, avoiding direct contact with the furnace chamber. The furnace door must be completely sealed.
Cooling: After the program is complete, allow the furnace to cool naturally or activate the forced air cooling system. Open the furnace and remove the sample when the temperature drops below 100°C.
2. Maintenance Points
Cleaning: Regularly clean the furnace chamber to prevent carbon deposits that affect heating efficiency.
Inspection: Quarterly inspect the thermocouple calibration, heating element connection status, and electrical circuit insulation.

IV. Safety and Design Advantages
1. Safety Design
Explosion-proof Structure: Equipped with a pressure relief valve and flame arrester, suitable for flammable and explosive working conditions.
Multiple Protections: Independent over-temperature protection, over-current protection, and door open/close sensor shutdown. ‌2. Energy-Saving Features‌
The waste heat recovery system can use exhaust heat for preheating fresh air or auxiliary heating, achieving an overall energy saving rate of ≥40%.

Main structures and components:

I. Main Structure
1. Shell and Frame
Material: Double-layer cold-rolled steel or 304 stainless steel, finished with a high-temperature paint or rust-proof finish. Corrosion-resistant and heat-resistant up to 300°C.
Support Design: The frame is welded and equipped with heavy-duty casters or adjustable feet for easy mobility and securement.
2. Inner Chamber and Insulation
Heating Chamber: Alumina fiber or ceramic fiber chamber, heat-resistant up to 1600°C, with strong thermal shock resistance to prevent deformation.
Insulation Filling: High-density rock wool or ceramic fiber (thickness ≥ 100mm) is filled between the double-layer shell, achieving a heat dissipation rate of ≤5%.
3. Door Design
Sealed Door: Side-opening double-layer door with built-in high-temperature silicone sealing strips and explosion-proof locks to minimize heat dissipation and ensure safe operation.

II. Core Components
1. Heating System
