Abstract
1292156 Container for float glass GLAVERBEL 8 Oct 1969 49435/69 Heading C1M [Also in Division F4] A method of making a refractory body which forms or is suitable for forming at least part of a float tank wall for use in a float glass process, is characterized in that a refractory mass 24 is east and one or more solid elements or pieces is or are pressed into the said concrete mass before it has set to form a layer covering at least part of a face of said mass, such elements or pieces being composed so that at least that surface of said layer which is remote from the cast mass has a composition different from the mass. The refractory mass 24, in the form of a concrete, can be formed from a combination of chamotte grains comprising 40-42% alumina, calcium aluminate and water. Other constituents which can be employed for forming a refractory concrete are corundum, sillimanite and alumina. The covering layer is composed of a material of higher thermal conductivity than the said mass, such as a carbon-rich layer, either in the form of blocks or as a rubble bound together by an agent which may incorporate fine carbon particles. The carbon layer prevents sticking of the glass and also assists in preserving the reducing atmosphere over a bath of Sn.
