Abstract
Large size (over 150 kg) ware which has to be fired in a kiln to form refractory ware is surrounded by muffling or upright lattice work in order to maintain a substantially uniform temperature gradient around the ware during firing in the kiln and during part of the cooling-down phase. The kiln used is a tunnel kiln and other ware to be fired may form the muffling or lattice work.
Claims7
In a process for burning ware of a size greater than 150 kg and having a wall thickness greater than 200 mm to form refractory products, the improvement which comprises processing the ware through a tunnel kiln and surrounding the ware with heat-resistant muffling or upright lattice work so as to maintain a substantially uniform temperature gradient around the ware.
