Basalt Fiber Drawing Production Line
Standard Description
CMT provides turnkey solutions for basalt fiber production equipment of various scales, integrating 3 patented technologies and professional R&D experience in the field. The production line realizes fully automated processes from basalt ore melting to fiber forming through all-electric melting technology. Compared with traditional glass fiber production equipment, it reduces energy consumption by over 40% and eliminates pollutant emissions. Equipped with a high-precision temperature control system, it ensures fiber diameter deviation ≤0.8μm and a finished product qualification rate of 99.5%. The line supports 24/7 continuous operation, suitable for large-scale production of basalt raw yarn, chopped strands, and high-performance composite materials.
Product Introduction
The production line adopts an "ore pretreatment -melting -drawing -oiling -winding" five-station integrated design, breaking through the technical bottlenecks of traditional basalt fiber production:
Melting System: Adopts advanced all-electric melting technology. Initial heating is performed by molybdenum disilicide rods, and switches to electrode heating after the ore is partially melted, ensuring uniform melting of basalt ore. The furnace structure is optimized via GB50017-2003 steel structure design standards, reducing heating time by 30% compared to traditional processes.
Drawing Module: Equipped with platinum-rhodium alloy bushing (400-800 holes, customizable), matched with water-cooled bushing coolers for energy conservation. A frequency-controlled online lubricator is installed below the bushing to ensure uniform coating of sizing agent on fiber surfaces.
Intelligent Control: Integrated with PLC system, enabling automatic feeding (20kg/h), real-time temperature monitoring (accuracy ±1℃), data acquisition, and remote monitoring. It supports communication with upper-level management systems, realizing visualized process management and automatic alarm.
Environmental Design: No waste residue or exhaust gas emissions during production; the closed-loop water circulation system achieves water reuse rate ≥95%, complying with GB 5959.1-2005 safety standards for electric heating devices.
Product Features
Natural Material Advantage: Uses 100% natural basalt ore as raw material without artificial additives, retaining the inherent high-temperature resistance (-260℃ to 800℃) and corrosion resistance (90% strength retention after 168h NaOH immersion) of basalt.
Efficient & Flexible Production: Single unit can operate independently, or multiple units can be combined (up to 20 units) to achieve annual capacity of 2000-4000 tons. The modular design supports quick switching between 7-23μm fiber diameters (changeover time ≤30 minutes).
Precision Process Control: The dual-mode heating system (molybdenum disilicide rods + electrodes) ensures stable melt viscosity; the radar level gauge controls molten liquid level fluctuation ≤±0.5mm, effectively reducing broken filaments.
Fully Automated Operation: Equipped with automatic ore feeding, intelligent bushing temperature control, and automatic doffing systems, reducing labor demand by 70% compared to traditional equipment. It can run continuously for 30 days without manual intervention.
Environmental Compliance: Dust emission ≤5mg/m³, no waste gas or residue discharge, meeting ISO 14001 environmental management system certification and EU environmental standards, suitable for high-end material markets worldwide.
Basalt Fiber Product Applications
Infrastructure Engineering: Reinforcement materials for bridges, highways, and marine engineering (service life ≥30 years, 2x longer than glass fiber materials).
High-Temperature Filtration: Filter materials for waste incineration flue gas (continuous operating temperature up to 260℃, filtration efficiency ≥99.9%).
Aerospace: High-strength composite materials for aircraft and spacecraft components (maintaining stability in extreme temperature environments).
New Energy: Fireproof bulkhead for new energy vehicle battery packs (resisting 1000℃ flame impact for 30 minutes without cracking).
