Abstract
A method for the continuous production of a cellular ceramic plate having asymmetric cells comprising thermally treating ceramic particles and a blowing agent in a foaming furnace while conveying said ceramic particles and said blowing agent at a first speed thereby forming a cellular ceramic plate, and annealing said cellular ceramic plate in an annealing lehr by cooling it down while conveying it at a second speed, larger than said first speed, thereby stretching and cooling said cellular ceramic plate.

1-16. (canceled)
A method for the continuous production of a one-piece continuous cellular ceramic plate comprising:
- a) thermally treating ceramic particles and a blowing agent in a foaming furnace while conveying said ceramic particles and said blowing agent at a first speed to thereby form a one-piece continuous cellular ceramic plate, and
- b) annealing said one-piece continuous cellular ceramic plate in an annealing lehr by cooling said one-piece continuous cellular ceramic plate down while conveying said one-piece continuous cellular ceramic plate at a second speed, larger than said first speed, thereby stretching and cooling said one-piece continuous cellular ceramic plate.
An apparatus for the continuous production of a one-piece continuous cellular ceramic plate comprising:
- a) a foaming furnace arranged to treat in one continuous piece ceramic particles and a blowing agent, said foaming furnace comprising a first conveyor adapted to convey at a first speed while heating said one piece continuous ceramic particles and said blowing agent to form a one-piece continuous cellular ceramic plate, and
- b) an annealing lehr arranged to anneal said one-piece continuous cellular ceramic plate by cooling said one-piece continuous cellular ceramic plate down, said annealing lehr being located downstream from said foaming furnace and comprising a second conveyor adapted to convey said one-piece continuous cellular ceramic plate at a second speed, larger than said first speed.
