Finally the guarantee of refractory quality and security supply in the current scenario of shortage mainly concerning natural refractory raw materials have drastically propelled the demand for synthetic raw materials. The combination of the several factors above has led to increase the importance and interest for monolithic refractories.

Jan 01 1982 · Insulation rarely adds to refractory life and may even reduce it. It does however save energy. In some furnaces for example in the large structures operated at relatively low temperature for annealing boiler equipment the walls are built completely of insulating material using bricks monolithic insulation or fiber blankets.
