The terms of “high performance” and “high cost-effectiveness” for refractories are so familiar. However, to answer questions like what the real meaning of high performance is, how to represent it, what the evaluation criterion is and how to realize high performance and meanwhile high cost-effectiveness seems to be not that easy without thinking in depth. For decent refractories, from original intention of design to production process, installation and on site service, each link is closely related to performance and cost, and in pursuit of, as much as possible, high performance and low cost. How to investigate subjectively high performance and how to feasibly realize low costs for refractories are worth further consideration and implementation by R&D workers and managers.
