摘要： The method and apparatus for forming an insert liner unit of the type having a plurality of refractory panels hingedly interconnected by a flexible heat destructible material. The apparatus includes a mold or forming assembly, a transfer table, a roll-over table and a transfer screen on which the unit is formed and which is used to transport the insert unit from the mold assembly through the transfer table to the roll-over table for depositing on a dryer screen. The mold assembly includes a vacuum box on which the transfer screen is supported, a mold which is moveable into engagement with the vacuum box to define the contour of the insert unit, and a pressurized air box to force water out of the slurry. The mold is filled with a predetermined amount of refractory slurry which is de-watered through the transfer screen to form a semi-rigid insert unit on the transfer screen. The transfer screen is automatically moved through the transfer table and into the roll-over table where the insert unit is transferred from the transfer screen to the dryer screen.

摘要： The method and apparatus for automatically forming a hot top bottom ring from a slurry containing a major portion of granular refractory material, minor portions of inorganic fibrous material and porous refractory material and a resinous binder. The apparatus includes a reservoir containing the slurry, a mold assembly, and a transfer mechanism for moving the mold assembly into and out of the slurry in the reservoir. The mold assembly includes an upper mold member and a lower mold member, the lower member being mounted for movement into engagement with and away from the upper mold member, and a vacuum system operatively connected to the mold assembly to draw the slurry from the reservoir into the mold assembly and to dewater the slurry during the movement of the mold assembly to a dryer screen. The fibrous bottom ring formed in the mold assembly is removed therefrom by the application of air under pressure to deposit the bottom ring on the dryer screen.
