MELTING SECTION

At the heart of stone wool manufacturing is the melting furnace, a critical component that
transforms raw materials into molten form for further processing. This essential stage lays the
groundwork for producing high-quality stone wool insulation.

The industry primarily relies on three types of melting furnaces, each offering unique benefits:
ELECTRIC MELTING FURNACES | GAS FIRED CUPOLA FURNACES
COKE FIRED CUPOLA FURNACES

Each furnace type plays a key role in optimizing efficiency, sustainability, and product quality, enabling manufacturers to meet evolving market requirements and strict regulatory standards.

ELECTRIC MELTING FURNACES

Sustainable Technology for Stone Wool Manufacturing

Electric melting furnaces are revolutionizing stone wool production by providing a cleaner and
more energy-efficient alternative to traditional melting technologies. Their precise temperature
control ensures consistent product quality while significantly reducing carbon emissions,
especially when powered by renewable energy sources.
The compact design of electric melting furnaces supports automated, space-saving operations,
making them ideal for sustainable and efficient manufacturing. As a result, electric melting
furnaces are becoming the preferred choice for manufacturers focused on high-quality, eco-
friendly stone wool insulation.

GAS FIRED CUPOLA FURNACES

Efficient and Adaptable Technology for Stone Wool Manufacturing

Gas fired cupola furnaces offer a modern and efficient solution for melting raw materials in stone
wool production, combining high thermal efficiency with lower environmental impact compared
to traditional systems. Their ability to provide consistent, controlled heat ensures uniform
product quality and reliable manufacturing processes.
Gas fired cupola furnaces are especially attractive in regions with abundant natural gas resources
and can be integrated with advanced environmental technologies to further reduce emissions.
By adopting gas fired cupola furnace technology, manufacturers can improve the sustainability
and competitiveness of their stone wool insulation products while meeting stricter
environmental regulations.

COKE FIRED CUPOLA FURNACES

The Proven Choice for Stone Wool Manufacturing

The coke fired cupola furnace is the most widely used technology for melting raw materials in
stone wool production, valued for its reliability and robust performance. Its operational flexibility
allows manufacturers to efficiently manage variable production demands and recycle production
waste, supporting sustainable manufacturing.
With lower maintenance and operating costs, as well as a durable design, cupola furnaces ensure
long service life and minimal downtime. Choosing a coke fired cupola furnace enables stone
wool producers to achieve consistent product quality, cost-effective production, and enhanced
environmental responsibility.
