Application of fractal theory in refractories production

Some applications of fractal theory in the production of refractories are introduced.Based on the applications,it is proposed that:Adding cryoprocessing procedure to the crushing and grinding process of the refractory raw materials can improve the efficiency of grinding,particularly can improve that of the hard materials;Studying the fractal structure of the powder can predict the flowability and filling status during press of the powder so as to improve the preparation,storage and conveyance of the powder;Studying the fractal structure of the crack can help to control grinding procedure by pre-feedback;Establishing the fractal grain size distribution can help to improve the property of the refractories;Adding powder or fiber with fractal structure can improve the strength and toughness of the refractories;Enhancing the study on the fractal structure of suction powder to prevent and control the occupational disease in refractories industry.
