CRYSTALLIZER FOR CASTING METALS AND THEIR ALLOYS AND A METHOD OF ITS MANUFACTURE Russian patent published in 2004 - IPC

FIELD: iron and steel industry; designs of moulds of any profile and a method of a mould manufacture.

SUBSTANCE: the group of inventions is dealt with the field of iron and steel industry, in particular, with a design of a casting mould of any profile and a method of its manufacture. The crystallizer has a step-down converging top-down profile and consist of a profiled cradle linked with a lamellar cover with a purpose to form a chamber for a refrigerating liquid. On the front wall of the cradle there is a set of the thermally fixed graphitic inserts located closely one to other and forming a casting surface. Each insert has one or two ledges, the upper of which has L -shaped form. Ledges of inserts are positioned in the grooves of the cradle without special fastening means and are kept just due to their preliminary cooling with following heating and dense fixation in the corresponding grooves of the cradle. Per each meter of the cradle perimeter there may be about 80 pieces of inserts, that may have both a rectilinear or a curvilinear outer surface, allowing to produce a high quality surface of casting of different form with simultaneous improvement of conditions of realization of the production process. The technical result is decreased consumption of source materials, duration of machining of manufactured pieces and assembly of the crystallizer, that results in decrease of costs of the metal ladling.

EFFECT: the group of inventions allows to decreased consumption of source materials, costs of the metal ladling and duration of machining of manufactured pieces.
