Electric Furnace Rock Wool Production Line

Main Components of Rock Wool Production Line

Feeding system: It is composed of storage bin, feeder, belt conveyor, etc., which can realize automatic metering, proportioning and transportation of raw materials.

Electric furnace smelting system: The core equipment is the electric melting furnace, which introduces electric energy into the furnace through electrodes to melt the raw materials at high temperature.

Fiber forming system: It mainly includes centrifuge, blow-off fan and other equipment to make high-temperature molten rock wool fiber.

Forming and curing system: It is composed of pendulum cotton spreading machine, pre-pressing machine, curing furnace, etc., which spreads rock wool fiber into uniform cotton felt, and solidifies the binder through the curing furnace to form a rock wool board with certain strength and shape.

Cutting and packaging system: It includes cutting equipment, packaging machine, etc., which cuts the cured rock wool board into specified size and packages it.

Control system: DCS control system is used to monitor and control the temperature, pressure, flow, speed and other parameters of the production line in real time.

Technical Advantages

Energy saving and environmental protection: The comprehensive energy consumption of SUNTHERM production line is reduced by more than 20%, carbon emissions are reduced by 10%, and sulfur dioxide emissions are reduced by 30%; the production line saves 4,100 tons of standard coal per year, and sulfur dioxide, nitrogen oxides, and dust emissions are reduced by 35%, 20%, and 30%, respectively.

High production efficiency: The maximum daily output of SUNTHERM electric furnace rock wool production line is 330 tons, and the annual output is 100,000 tons; our company's production line in Luoyang produces 150 tons per day and an annual capacity of 50,000 tons.

Good product quality: The acidity coefficient of SUNTHERM rock wool production line products is as high as 2.0, and the thermal conductivity of exterior wall products is as low as 0.036W/(m・K).

High degree of intelligence: The entire production line can be operated under the DCS control system, reducing manual intervention and improving production stability and product quality consistency.

Application Fields

Construction field: used for exterior wall insulation, roof insulation, fire isolation belts, etc. of buildings, which can effectively improve the thermal insulation performance and fire safety of buildings.

Industrial field: as thermal insulation materials for industrial equipment and pipelines, it can reduce heat loss and energy consumption. It can also be used for roof and wall insulation of industrial plants, as well as fire separation.

Other fields: It is also widely used in chemical, electric power, transportation and other industries, such as anti-corrosion and thermal insulation of chemical equipment, thermal insulation of power pipelines, and fire insulation of ships.
