Abstract

PURPOSE:To provide a trough for the smooth discharge of molten glass, etc., composed of a metal having a thermal conductivity of higher than a specific level and inertness to water, and coated with a carbide cermet or a nitride cermet, or composed of a graphite plate having a thermal conductivity defined above. CONSTITUTION:A trough for discharging molten material such as molten glass, composed of either a metal plate (e.g. Cu, Al, etc.) having a thermal conductivity of >=70KCal/m.h. deg.C at 20 deg.C and inertness to water, and coated with a carbide cermet (e.g. a nickel graphite cermet such as WC-Ni) or with a nitride cermet (e.g. BN) or a graphite plate having a thermal conductivity of >=70KCal/m.h. deg.C at 20 deg.C. The drawbacks of the conventional trough made of iron, e.g. necessity of steep gradient, necessity of a large amount of water, scattering of water to the surroundings, generation of large amount of steam, etc., can be eliminated by the use of the trough of the present invention.
