The mold MODEL FOR INVESTIGATION OF ingot crystallization

摘要

The invention relates to metallurgy, in particular to devices for studying crystallization ingots. The technical result is the ability to study the processes that occur during solidification and structure model ingot mold in various configurations under conditions of intense heat sink in the head and the bottom of the ingot and the rapid solidification of the ingot to all horizons and to predict the location and development of the shrinkage defects in the real ingot for hollow forgings. mold model for investigation of the crystallization process ingots, comprising a metal frame with a water cooled cavities on the perimeter of which are fixed transparent glass, the hot-top, the fittings for supplying and draining water, wherein the metal frame is made detachable from the bottom and side walls connected to a bottom portion hingedly tiltable at an angle from 42 ° to 116 °, wherein the bottom portion is concave to the feed head, wherein the ratio of the height of the mold from the concave portion to the plane based Ia the feed head to the average diameter of the mold is: H _rad / D _cf. = 1.1 ÷ 1.5, where H _rad - the height of the mold from the plane of the concave portion to the base of the feed head in cm; D _Wed - average diameter of the mold, see, characterized in that the feed head is made water cooled from a material with high thermal conductivity with connections for the supply of water in the hot-top and its outlet in a water cooled cavity metal frame and exit through the bottom portion, the height ratio of the hot-top. a mold height from the plane to the concave bottom portion of the feed head to the base of the hot-top is: h / H _rad = 0.2 ÷ 0.4 where h - height of the feed head in cm;_Rad H - height of the mold from the plane to the concave bottom portion of the feed head to the base of the feed head, see.
