ABSTRACT:
A solid or perforated plate, serving as a support for a screen conveyor in paper-making machinery or the like, consists of a multiplicity of juxtaposed coplanar sections of sintered refractory, predominantly ceramic material joined to one another by thin layers of a bonding agent. The ceramic component, e.g. alumina, may be admixed with a small proportion of a vitreous substance facilitating the use of a siliceous bonding agent, such as glass, enamel or silicon carbide. Alternatively, the bonding agent may be a solder (with preliminary metallization of the adjoining section edges) or an organic cement.
A method for making the plate includes filling gaps between the sections with a bonding agent of silicon carbide formed by melting pieces of graphite in the gaps in an atmosphere of silicon vapor, thereby uniting the sections.
