Abstract
A discharge opening for a reheat furnace is shielded with a pair of metal woven wire mesh curtains each secured above the discharge opening and hanging to the bottom of the opening. Each curtain preferably is formed from multiple parallel coplanar ribbons, each extending from above the discharge opening to the bottom of the discharge opening. The mesh curtains are fabricated from a sag resistant metal alloy. Embodiments are described for accommodating slots which receive discharge lifter members for removing heated metal workpieces from the furnace. A preferred mounting apparatus employs one or more fibrous thermal insulation strips above the discharge opening. A counterweight mounting apparatus urges the fibrous thermal insulating strips against the outer wall of the furnace.
