摘要：

In recent years, in refractories industry, a cost supreme principle occupies the mainstream and even a technical feeling of a blockade is sensed. Much more high purity steel and strict component control steel will be reqired in the future, and the request to the ultra low carbon containing refractories in refining and casting of steel is indispensable. Realization of nanotech refractories based on the nano structural matrix is expected as a leading measure. If the further leap of refractories technology is aimed at, introduction of the new technology which exceeded the existing frame on the occasion of development is indispensable. In this report, with the following two control technologies, nano structural matrix is developed and the direction towards utilization of nanotech. Refractories is shown two control technologies are, a)control of the packing structure by dispersion of the nano particles of various shapes, or the pore structure by modification on the surface of a coarse grains, and b)control of the combined structure in the heat-treatment process of binding materials.
