The present invention relates to a method for manufacturing a tube-type spray formed product and, in particular, to a method for manufacturing a tube-type spray formed product without using a core. The present invention provides a method for manufacturing a tube-type spray formed product in which a tube-type spray formed product is formed by spraying droplets through an atomizer installed at the position separated from the center portion of a rotating plate as much as the droplets should not sprayed on the center portion of the rotating plate.

The present invention relates to a continuous shear deformation device. In order to occur shear deformation at the position at which a material is inserted into a molding path from a rotary guide apparatus for the purpose of solving the problem that the amount of shear deformation of a material is non-uniform and insufficient due to the gap between the curved portion of the molding path and the lower parts of the material, there is provided a continuous shear deformation device, characterized in that a curved portion is constructed by collaboration between the rotary guide apparatus and the molding path. In addition, there are provided additional constructions for effectively performing shear deformation by a small power by reducing the friction at the molding path excepting the curved portion. The present invention thusly constructed can be utilized for continuously and effectively mass-produce sheared materials.

The present invention relates to a shear deformation device. To improve the productivity by solving the problem that the amount of shear deformation of a material is not uniform and sufficient due to the gap between the curved portion of the molding path and the lower parts of the material and omitting any additional process for removing irregularity and surface products on the surface of the material, there is provided a shear deformation device capable of scalping, characterized in that a scalping guide path which allows the surface of the material to be separated from the other portions of the material as the material is scalped at a predetermined thickness when passing through the curved portion during shear deformation is formed in the curved portion in communication with the molding path. In addition, there are provided additional constructions for effectively performing shear deformation by a small power by reducing the friction at the molding path excepting the curved portion. The present invention thusly constructed can be utilized for continuously and effectively mass-produce sheared materials.

The present invention relates to processes of regenerating Ni catalysts which had been used in a hydrogenation of unsaturated fatty oil or petroleum resin, which comprise separating the Ni-extracted solution and support by extracting the pretreated Ni catalysts with an acid, preparing support-containing solution by burning the separated support in the flow of air or oxygen diluted with nitrogen at the temperature of 300.degree. to 800.degree. C. for 5 to 15 hours and adding deionized water to the support, preparing a catalyst precursor by dropping the Ni-extracted solution and the mixed solution of a basic compound and a compound with free oxygen in the support-containing solution during agitation so as to keep PH of the solution at 9 to 13, whereby nickel oxide precipitates on the support, carrying out a step consisting of aging, washing, filtering and drying the catalyst precursor, and stabilizing the dried catalyst precursor by reducing with hydrogen and passing in nitrogen diluted with oxygen or an organic material.
