Mathematical simulations of extrusion forming of the large-sized porcelain blankets of increased reliability

A computational and experimental study of the technological process of mouthpiece pressing of large-sized porcelain covers has been carried out. Mathematical modeling of the process of pressing cylindrical tubular billets from an alumina mass, which is presented as a non-Newtonian fluid, performing a laminar flow through the forming channel of a vacuum press, has been carried out. Recommendations are given on the choice of a rational configuration of the forming system of a vacuum press for the production of a cylindrical tubular semi-finished product.
