METHOD FOR PRETREATING HONEYCOMB FORMED ARTICLE BEFORE FIRING
A method for pretreating an unfired honeycomb formed article of a raw material composition containing a ceramic raw material, water, and a binder and having a plurality of cells separated by partition walls and functioning as fluid passages before firing. The method has a first step of passing superheated steam having a temperature of 100 to 150°C through the cells to raise temperature of the honeycomb formed article and then maintaining the temperature of the superheated steam at the temperature of the superheated steam passed through the cells or more and 200°C or less. The method can provide a pretreatment to a honeycomb formed article in a shorter time with inhibiting generation of a defect such as a deformation or a damage.
