摘要
应用分形理论研究了低硅烧结矿的抗压强度。结果表明：应用分形理论来定量描述烧结矿的微观结构是切实可行的,其分形维数介于1.1-1.6之间;1 300℃是分形维数和抗压强度的极大值温度点,在温度两侧抗压强度均随分形维数的增加而提高;1 300℃以下,分形维数和抗压强度随温度的提高而增加,1 300℃以上,规律性不明显;定量表征了微型烧结温控是1 300℃的机理。
The intensity of the low silicon sinter is studied by fractal theory.The results show that it is workable to character microstructure of sinter quantificationally,the value of fractal dimension is 1.1-1.6;The value of fractal dimension and intensity reach to the max when the temperature of the sintering is 1 300 ℃.The intensity is increased with the adding of fractal dimension on the either side of 1 300 ℃.The fractal dimension and the intensity is increased with the adding of sintering temperature below 1 300 ℃,but the regularity is not obvious above 1 300 ℃.The mechanism of the temperature controlling of macro sintering experiment quantificationally（its value is 1 300 ℃） is characterized.
