Refractories Co., Ltd., Zhengzhou City shangzhuang understand some materials, such as silica-alumina refractory products, it is generally believed that at a certain temperature (eg within the following 700 ~ 900 ℃ in the elastic range) chemical furnace refractories, the higher the temperature wear resistance property (Wear resistance), the lower, can be considered when the temperature was increased with the increase after the elastic modulus, abrasion resistance (Wear resistance) decreased. When the temperature rises, the elastic modulus reaches a maximum value after chemical furnace refractories, with the decrease of the elastic modulus, abrasion resistance (Wear resistance) but improved. Aluminosilicate refractory products such as during 1200 ~ 1350 ℃, abrasion or even better than those at room temperature. When the temperature is further increased, reaching more than 1400 ℃, the result of refractory products in liquid viscosity drastically reduced wear (Wear resistance) decreases. Some quality refractory products such as chromium, with increasing temperature furnace refractories chemical, abrasion (Wear resistance) increases. Refractoriness refractory how? Refractories Co., Ltd., Zhengzhou City shangzhuang tell you: refractoriness is not a matter of absolute unique physical chemical furnace refractories, the material was measured under specific test conditions to achieve specific soften extent relative technical indicators. The test method for materials required to make the truncated cones (the test cone), with a fixed bend down at a specific temperature, heating rate standard temperature cone frustum triangle (the standard cone), jointly established the heating rate and a certain atmosphere Under the conditions of heating, bending down to test the extent of the cone with the standard curve inverted cone contrast method for the determination of comparable refractoriness.
