    摘要: A gas pressure bonding furnace having a convection shield with (1) monolithic tubular refractory insulation having its upper end surrounding the work receiving hot zone of the furnace and its lower end depending to a cool zone, (2) an impervious tubular metal shell surrounding the tubular insulation and holding it under compression by differential thermal expansion, (3) a cover closing the top of the shell by a gas tight gasket seal and (4) a piston actuated by the gas working pressure to hold the cover closed. In a preferred form, the insulation is cast in the shell and the composition is an alumina cement with embedded alumina balloons.
