Abstract: A cast web formed on a support in a casting process is peeled off the support by a first roller in a peeling and conveying process. As being peeled by the first roller, the cast web forms a film, and conveyed through a second roller to a tenter drying process.

The first and second rollers are concave rollers. A couple of blowers are disposed at the end of the peeling and conveying process, to blow the lateral sides of the film in laterally outward directions of the film, to stretch curls in the lateral sides of the film.

Abstract: Provided are an apparatus and method for manufacturing a solidified salt that is easy to treat in size and shape by using a vacuum transfer and a dual vessel. In the apparatus for quantitative solidification of a molten salt, a molten salt is introduced into a first vessel, and a second vessel is disposed inside the first vessel and quantitatively supplied with the molten salt. A molten-salt transferring unit quantitatively transfers the molten salt from the first vessel to the second vessel by vacuum pressure. A valve controls a discharge of the molten salt from the second vessel. A mold receives the molten salt from the second vessel and solidifies the molten salt. Accordingly, the molten salt can be stably discharged to the mold by quantitatively transferring the molten salt at vacuum pressure within the dual vessel, and a predetermined size and shape of the solidified salt can be manufactured, thereby processing and collecting the solidified salt safely.

The difference between a target shrinkage and the estimated shrinkage is determined, and one or more of the processing conditions used to form the ceramic body are changed to offset the difference.

Abstract: A component can be formed by a hot isostatic pressing (HIP) process but it is necessary to reinforce intricate internal structures against collapse and deformation by the hot isostatic pressing process. The present method utilizes a low melting point salt or alloy reinforcement within the structure which can be released when molten through a drain from the internal structure. The reinforcement may be molten as a result of the hot isostatic process or through achieving a temperature with the component which causes the reinforcement to become molten but without damaging the component itself. The remaining parts of the reinforcement may be removed by use of a solvent or simple washing with a corrosive agent to remove any reinforcement debris.
