Description
1. Production Line Process
(1) Raw Material Preprocessing
Intelligent Proportioning: Basalt (60–80%), slag (20–40%), binder (phenolic resin ≤3%).
Automatic Crushing and Screening: Particle size controlled between 0.5–5 mm to ensure uniform melting.
(2) Natural Gas Melting System
Regenerative Combustion Technology: Furnace temperature stable within ±10℃, energy consumption ≤120 m³ natural gas per ton of rock wool.
Low NOx Emission: Nitrogen oxides <100 mg/m³, exceeding national ultra-low emission standards.
(3) Centrifugal Fiberization
Four-Roller Centrifugal Machine: Fiber diameter 3–7 μm, slag ball content <10% (national standard ≤15%).
Negative Pressure Fiber Collection System: Uniform fiber distribution with error ≤5%.
(4) Curing and Forming
Intelligent Stacking: Multi-layer staggered placement increases tensile strength by 20%.
High-Temperature Curing Furnace: Temperature gradient control (200–250℃), curing time reduced to 10–15 minutes.
(5) Cutting and Packaging
Laser Positioning Cutting: Dimensional accuracy ±1 mm, supports custom sizes (board thickness 30–200 mm, width ≤1200 mm).
Automatic Palletizing and Packaging: Daily output 10–30 tons depending on line configuration.
