Lining and Repair
Lining
Thanks to both the extraordinary efforts of specialist engineers and the application of state-of-the-art refractory technologies, blast furnaces nowadays only need a new lining once in a generation. A Lifespan of 20 years or longer can be achieved easily, making the demands on refractory products extremely high.
Therefore the quality of the related monolithic products (gas seal bell, dome, start-up protection) is of enormous importance. WEERULIN has more than 30 years experience working with refractory mixes in blast furnace linings. Our products are perfected, well proven and absolutely reliable.
Repair
When it comes to interim repairs, the main factor is time. Each day of downtime is extremely costly. Therefore, repair jobs must be carried out within a very tight timeframe.
WEERULIN has been helping with interim repairs in blast furnaces for decades: providing service as well as products. You can rely on our time management. We use state-of-the-art robot gunning systems and moveable platforms. WEERULIN has also been working as main contractor in turnkey projects and always delivers the blast furnace in time.
