Detailed Product Description: | Refractories (Refractory material) of air permeability air permeability allows gas to pass through the material under pressure performance. Since the gas through the permeable material through the pores, the air permeability of the through pores of size, number, and the state of the structure, and with the pressing direction during molding of refractory products varies. It and the porosity of a relationship, but no regularity, and again, and the porosity is different. Certain refractories (Refractory material), an air permeability is critical indicators refractories, directly affect its anti-corrosion medium, such as slag, molten steel, molten iron and various gases (steam) erosion resistance, oxidation resistance, breathability functions. For some materials, such as flame or hot gases for isolation or in direct contact with the slag, the molten metal article, is required to have a very low air permeability; and some functional refractory materials wholesale, there must have a certain air permeability. Refractories (Refractory material) of the air permeability of the direct impact of the production process by its refractory agent, by controlling the ratio of the particles, forming pressure and firing system can control the permeability of the material. On the air permeability of dense shaped refractory products, in accordance with the national standard GB / T3000-1999 (equivalent to international standards ISO8841: 1991) were measured. With China's accession to the WTO, domestic refractories (Refractory material) and refractory products challenges abroad longevity, energy, functional new products, the market is increasingly competitive. In this regard, the experts pointed out that China should accelerate the optimization and adjustment of the refractory industry, implementation of powerful alliances, eliminate backward production lines refractory low, strengthen research and production operations, the adjustment of product structure to meet the needs of domestic and international steel industry as soon as possible.
