Roller-Type Coated Sand New Sand Heating Furnace

Uniform Temperature, Precise Control
Multi-zone external heating with multi-point thermocouples + PID control ensures internal temperature deviation ≤±15°C—consistent material heating.

Energy-Efficient, Low Operating Cost
Double-layer insulation (ceramic fiber + refractory brick) keeps surface temperature ≤50°C, minimizing heat loss. Gas models ≥85% thermal efficiency; electric model  be equipped with waste heat recovery.

Robust Structure, Stable Operation
Drum made of Q345R boiler steel or heat-resistant stainless steel (310S). Precision-machined rollers and riding rings ensure smooth, low-vibration operation—service life ≥10 years.

Intelligent Control System
PLC + 10" HMI touchscreen supports multi-stage heating profiles, data logging, fault alarms, remote monitoring (optional), and integration with MES.

Safe & Reliable, Easy Maintenance
Equipped with over-temperature protection, gas leak alarm (gas models), emergency stop, explosion relief port; wide access doors and quick-change components simplify maintenance.

Eco-Friendly, Green Production
Exhaust treatment effectively removes dust and harmful gases—emission ≤30mg/m³, compliant with national standards.

Continuous drying and curing of resin sand cores and shell cores in foundries

Calcining of high-alumina bricks and magnesia-carbon brick blanks

Regeneration of catalysts, molecular sieves, and desiccants in chemical industry
