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.

Tall work-supporting elements, riders or buttons, for reheat furnaces increase the unshadowed area of radiation exposure for the under surface of steel workpieces and thereby significantly reduce the 'skid mark' phenomena of workpieces. The tall supporting members are secured to horizontal water-cooled skids and have internal flow passageways to receive cooling water.

A rider for use with lengthwise generally horizontal supports in a furnace is formed from an anchor block and a cover block and a locking means. The anchor block is secured to the lengthwise generally horizontal support surface. The cover block fits vertically onto the anchor block and can be moved forwardly into a locking position which prevents vertical, forward, or lateral movement of the cover block. A locking means between the anchor block and the cover block prevents rearward movement of the cover block. The cover block is replaceable without requiring removal and replacement of the anchor block.
