Summary

The manufacture of ceramic products like refractory bricks involves the use of several different types of raw materials and different size fractions of these materials and a multiplicity of manufacturing processing steps. The large number of critical factors that may influence the final brick properties is compounded by the fact that interactions among and between compositional and processing factors often exist. A study to demonstrate the manner in which parameters critical to a ceramic process can be identified has been undertaken using the refractory brick manufacturing example. Screening experiments suggested by Plackett and Burman and by Box and Hunter have been carried out to identify the significant processing factors to be studied in and “response surface” experiment. The response surface experiment is then used to construct mathematical models that may predict the manner in which a process will respond to manufacturing inputs. The response surface is used to identify the degree to which process parameters must be controlled to achieve the desired product tolerance level. In addition, this understanding is essential for the implementation of effective automated process control. A summary of the process factors critical to green density of refractory brick is shown to demonstrate the techniques.
