Skamol A/S produces and develops insulation materials for high temperature industries in close cooperation with the industry. The broad range of insulation products provides countless possibilities of reducing costs and improving carbon footprint.
Challenges often faced in high-temperature industries are ways of minimising production costs while increasing production and reducing CO2 emissions at the same time. Insulation of the production equipment can contribute to solving these challenges.
Among its large product portfolio, Skamol A/S has developed VIP-900 and VIP-12 HS that are very applicable for use in e.g. steel ladles and torpedo cars as backup insulation. A low thermal conductivity of 0.23 W/(m x K) at 200° C and a still low 0.30 W/(m x K) at 1000° C ensures that heat can be preserved inside the e.g. ladles and thereby minimizing heat loss and fuel consumption. Studies have shown that the CO2 emissions can be reduced with up to 5.500 ton/year for a plant of 5 mio. tons of steel/year. The unique blend of ingredients and production methods used to produce the insulation materials mean that the VIP products gain strength as they get warmer – up to 600° C. Using this strong backup insulation makes it possible to increase the number of heats between relinings and reduce costs of relining.
For insulation of rotary Kilns, Skamol A/S has developed M-EXTRA - a diatomite insulating brick. Besides reducing energy costs, using M-EXTRA minimises problems like deformation of shell and stress on wear parts and hereby reducing maintenance costs. Examples have shown that using M-EXTRA can lower the shell temperature with up to 64 % and due to the insulation, CO2 emissions can be reduced with up to 64.000 ton/year.
A significant difference between the M-EXTRA and chemically bonded bricks is the fact that most chemically bonded bricks loose strength when reaching app. 700° C, while the M-EXTRA bricks gain strength up to app. 900° C – making the rotary kiln stronger and thereby less effected by the heat.
