30000 TONS/YEAR FULLY AUTOMATIC ELECTRIC FURNACE ROCK WOOL PRODUCTION LINE

Product Overview

The electric furnace rock wool production line uses an electric resistance furnace as the core melting device. Through high-temperature processing, natural rock and auxiliary materials are fully melted and transformed into high-performance rock wool products. These materials are widely used in building insulation, industrial pipeline protection, acoustic noise reduction, fire isolation, and thermal insulation for high-temperature equipment.

Electric furnace rock wool is characterized by low energy consumption, environmental friendliness, structural stability, and fine and uniform fibers. These advantages make it a mainstream technological solution in the rock wool industry. The production line features full automation control, mature and reliable technology, high production efficiency, and stable product quality, meeting modern building energy efficiency standards and the stringent requirements of industrial high-temperature applications.

Product Structure and Components

Electric Furnace Melting System

Uses a high-performance electric resistance furnace with precise temperature control and uniform heat distribution. It supports multiple raw material formulations, offers high melting efficiency, stable operation, and long service life.

Spray Fiber Formation System

High-speed airflow is used to stretch molten material into fine fibers, creating a uniformly distributed and delicate rock wool fiber layer.

Fiber Collection System

Composed of a forming chamber, conveyor belt, and vacuum adsorption device, this system ensures uniform fiber deposition and continuous production of rock wool mats and boards.

Cutting and Forming Equipment

Equipped with automated cutting machines and shaping devices, enabling processing of rock wool boards and custom-shaped components in various specifications.

Drying and Curing System

High-efficiency drying and curing equipment ensures rapid shaping of products and guarantees mechanical strength and dimensional stability.

Automatic Packaging System

Automates product packaging to improve efficiency and facilitate storage and logistics transportation.

Technical Parameters

Process Flow

Raw Material Preparation
