Popis:	A principally novel technology for molding and compacting articles from low-moisture powder materials by continuous zonal injection directly into open molds is suggested. The method excludes air inclusions, the elastic aftereffect, the inaccuracy of the sizes of the articles, and other defects typical for cyclic semidry pressing. The use of the new technology in the production of refractories makes it possible to increase their density, decrease the forces acting on the material by 1 – 2 orders of magnitude (i.e., to the ultimate strength of the greenware), increase the accuracy of the sizes, decrease the expenses per unit product, and increase the output of the molding equipment.
