Abstract
A roof assembly for a furnace comprising at least one segment ( 12.j) comprising a single integral metal body (22) comprising copper. The body has opposed first and second faces (26 and 29) and the body defines channels (50) for a cooling fluid drilled into the body to extend between the first and second faces. Each channel comprises at least first and second intersecting circular channel parts (52, 54).
