Abstract
In a method of firing ceramic formed bodies including a binder by using a firing furnace having one or more burners in which a firing output changes alternately between a high output state and a low output state, an air ratio of the burner is maintained at a level of more than 3 in a temperature range from a temperature at which the binder begins to burn out to a temperature at which an ignition loss reaction ends. Further, a firing apparatus has a control means for controlling the burners according to the firing method mentioned above.
Claims5
A method of firing ceramic formed bodies including a binder by using a firing furnace having at least one burner in which a firing output changes alternately between a first output state and a second output state that is lower than said first output state, comprising a step of maintaining an air ratio of said at least one burner to a level of more than 3 in a temperature range from a temperature at which the binder begins to burn-out to a temperature at which an ignition loss reaction ends.
