METHOD OF HONEYCOMB MOLDING PRETREATMENT FOR BURNING AND SYSTEM FOR HONEYCOMB MOLDING PRETREATMENT FOR BURNING

摘要

A method in which an unburned honeycomb molding which has been formed from a raw-material composition comprising a raw ceramic material, water, and a binder and has cells serving as fluid channels and separated by partitions is subjected to a pretreatment for burning. The method includes a first step in which 100-150°C overheated water vapor is passed through the cells to heighten the temperature of the honeycomb molding and then the overheated water vapor being passed is kept at a temperature which is not lower than the temperature of the overheated water vapor having been passed through the cells and is not higher than 200°C. By the method of honeycomb molding pretreatment for burning, the honeycomb molding can be pretreated prior to burning in a shorter time while inhibiting the occurrence of troubles such as deformation and breakage.
