1300℃ Bell-Type Furnace

1300℃ Bell-Type Furnace Technical Specifications

• Maximum Service Temperature: 1300℃
• Continuous Operating Temperature: 1280℃
• Control Range: 80–1250℃
• Temperature Measuring Element: Thermocouple Type K, measuring range 0–1320℃
• Heating Elements: U-shaped silicon carbide (SiC) rods, arranged around the chamber, max temperature up to 1500℃
• Temperature Control Accuracy: ±1℃ (integrated circuit control, no overshoot)
• Furnace Temperature Uniformity: ±5℃
• Heating Rate: Fully adjustable; maximum 30℃/min, minimum 1℃/h
• Furnace Body: CNC-machined, polished, pickled, phosphated, powder-coated, and baked at high temperature; resistant to oxidation, corrosion, acid/alkali, and high temperatures, with easy cleaning
• Furnace Structure: Advanced air-cooled double-layer structure; guided airflow prevents overheating and oxidation of heating element conductors, ensuring safe and stable operation
• Lifting System: Double-cylinder hydraulic lifting with manual lowering button in case of power failure; equipped with mechanical safety lock to prevent accidental falling
• Loading Platform: Vertical lifting bell-type opening; multi-layer soft seal steps with elastic high-temperature strips and sealing sand structure for excellent airtightness and thermal expansion absorption
• Loading Platform Refractory: Vacuum-formed high-purity alumina lightweight material combined with alumina hollow ball plate for both insulation and load-bearing capacity
• Chamber Refractory: Vacuum-formed high-purity alumina lining; furnace mouth and bottom reinforced with lightweight alumina hollow ball plates; resistant to rapid heating/cooling, cracking, and slagging; thermal efficiency >80% compared to conventional furnaces
• Insulation System: Three layers—aluminum silicate fiberboard, alumina fiberboard, polycrystalline alumina fiberboard—ensuring high energy savings (>80% vs. traditional designs)
• Furnace Shell Temperature: ≤45℃ during continuous operation
• Protection System: Integrated modular control unit with dual-loop system (control + protection), offering safeguards against overshoot, phase loss, overvoltage, overcurrent, overtemperature, and more
• Control System: Closed-loop thyristor (SCR) trigger control; supports phase-shift or zero-crossing trigger; constant voltage/current/power modes; ensures reliable regulation and heating element protection
• Touchscreen Interface: 7-inch display for real-time monitoring and storage of temperature, segments, time, remaining time, output power %, voltage, and current
• Temperature Curve Programming: FP03 intelligent temperature controller (Japan); supports PID, AI-based APID/MPT control; self-tuning and self-learning; 40-segment programmable curves for precise heating/cooling; functions include jump (loop), run, pause, stop, and on-the-fly program editing
• Spare Parts: Two heating elements, two sets of rods
• Warranty: One-year free warranty (heating elements excluded, but free replacement within 3 months if natural damage occurs)
• Packing List: Furnace ×1, heating elements ×2, rods ×2, high-temperature gloves ×1, manual ×1, certificate ×1, inspection report ×1, delivery note ×1
