Abstract (en)
A trough cover (1), comprising a plurality of cover (2) panels, encloses a trough (t) adapted to carry hot molten material (m) to contain gaseous emissions and heat released from the molten material (m) and to prevent foreign matter from entering the trough. Each panel (2) comprises a channel-shaped support member (5) and a refractory member (6), preferably a ceramic fiber material-type refractory, the refractory (6) covering the surface of the support member (5) exposed to the molten material. A fastening means (9) secures the panels (2) together to form the top (3) and side walls (4) of the cover (1) whereby and essentially continuous refractory interior surface (10) is formed by the refractory members (6). The refractory insulates the fastening means (9) and the support members (5) of the panels (2) from the molten material (m). In alternate embodiments, stiffening flanges are provided on the support member and a handle rod is provided to facilitate lifting of the cover when covering or uncovering the trough.
