Refractory Bricks Fire For Coke Oven
The properties of clayey products fluctuate over a wide range due to the wide range of chemical composition of the products (Al2O3 content fluctuates between 30 and 46%) and to the differences in production processes.The refractories of clayey products fluctuate from 1580 ℃ to 1770℃, which depends mainly on the chemical composition of the products and increases with the increase of Al2O3/SiO2 ratio.The increase of flux impurities, especially alkali metal oxides, will significantly reduce the refractoriness of the products.The softening temperature under load depends mainly on its chemical mineral composition and density, but the latter does not affect the final softening temperature under load, but increases the initial deformation temperature.Low volume density of brick will also lead to lower initial temperature of load softening.Therefore, to improve the starting temperature of clay products under load softening, we should start from the following aspects: to increase the content of Al2O3 in the products, especially the content of Al2O3 in the matrix;Increase the firing temperature and use more clinker ingredients;Improve the bulk density of the formed brick.
