The choice between kiln T3 clay bricks and high-alumina bricks depends on a number of factors, including the environment in which the kiln will be used, process requirements, budget, and the required fire resistance. Environment: If the working temperature of the kiln is high, and there are high-temperature heat and chemically aggressive substances, such as metal smelting furnace, glass kiln, etc., it may be more suitable to choose high-alumina bricks, because high-alumina bricks have good thermal shock resistance and erosion resistance at high temperatures. If the kiln operating temperature is low and particularly high fire resistance is not required, such as brick kilns, T3 clay bricks may be a more economical and suitable choice. Process requirements: If the process in the kiln requires special treatment of the product, such as high-temperature calcination, chemical reaction, etc., the stability and durability of the material need to be considered. In this case, a high-alumina brick may be more suitable because it has higher resistance to thermal shock and erosion. If the process in the kiln is not demanding, just for general firing or heating, T3 clay bricks may be a more economical and suitable option.
Budget: T3 clay bricks are usually cheaper than high-alumina bricks considering the budget factor, so if the budget is limited and the working conditions of the kiln do not require particularly high fire resistance, T3 clay bricks can be selected to save costs. According to the above content, the choice of T3 clay brick or high-alumina brick for kiln should comprehensively consider the use environment, process requirements, budget and other factors of the kiln to find a satisfactory product.
