1. Product Overview
The Coke Furnace Rock Wool Production Line is mainly used to produce high-performance rock wool materials by melting natural basalt, iron ore, diabase, and other raw materials at high temperatures, followed by centrifugal fiberizing or blowing fiberizing, binder mixing, forming, and curing processes.
The produced rock wool products feature uniform density, precise dimensions, excellent thermal insulation, and fire resistance. They are widely used in coke plants, high-temperature pipeline insulation, heat treatment furnaces, metallurgical equipment, and industrial buildings for thermal insulation, energy saving, and fire protection.
2. Production Process
▶ Raw Material Preparation
- Selection of high-quality basalt, diabase, iron ore powder, and other raw materials
- Crushing, screening, and accurate proportioning
- Addition of inorganic binders to improve product stability
▶ High Temperature Melting
- Raw materials are melted in electric furnaces or gas furnaces at 1450℃-1600℃
- Uniform molten material with excellent fluidity ensures efficient fiber formation
▶ Centrifugal or Blowing Fiberizing
- Molten rock is transformed into fibers through high-speed centrifugal spinning or air blowing technology
- Fiber diameter can be controlled according to different density requirements
▶ Forming and Curing
- Fibers are evenly distributed and mixed with inorganic binders
- Vacuum forming, hot pressing, or self-curing molding technology
- High-temperature curing improves mechanical strength
▶ Cutting and Packaging
- CNC cutting equipment enables production of various sizes of boards and blankets
- Moisture-proof packaging ensures safe transportation and storage
