SK-34 firebrick in China indicated that clay firebrick. Refractoriness refers to the temperature at which the data reaches a specific degree of softening under the effect of high temperature, and represents the function of the data to resist the effect of high temperature. Refractoriness has a different meaning than melting point. The Al2O3 content of clay bricks in China is generally more than 40%, and the FeO content is less than 2.0 ~ 2.5%.
SK(Seck cone) is a brand indication method in foreign refractory bricks can also be called refractories indication method, is a test target to indicate the title, just like our domestic is to use T or G to indicate the brand of refractory bricks. sk-34 firebrick in China indicated that clay firebrick.
