The purpose of the game is to increase the complexity of the process, to improve the quality of the cast material for the rotation of the process,

The method of mining a sicnpepbmHo ™ for casting the blanks is as follows. pomotu dztchrgkot installed with some steps along its length ..

It has been established that the temperature of the 1e wall is maximal in the zone of the rupture of the workpiece and decreases in a napron lane to the ends of the crystallizer.

With a bullet eon rupture, the temperature of the copper wall is maximally 1a fi the center of the crystallizer 5 a b, equidistant from 1 2Ntra single temperature points;; gogopkt rat.) w.

When the rupture zone is displaced to one or another stern-center from the center of the equipment, the temperature at the center point of the padata, and at the points equidistant from the center of the center, there is a gap, the temperature is proportional to the size of the segmentin.

When shifting right to the right, the structures in the top, located on the right of the center of the attorney stan- dards, are urshchivatsa, and in, located with the Eva, decreases; In this case, the flow rate in the right side of the crista.pplator is reduced, and the melt flow rate of the left crystallizer is reduced. The ratio of the flow rates of the alloy in the ne, and the right part is determined by the formula I

The ratio of the flow rates of the rasplapl is also determined by the gyu form; R I.

Based on the experimental data, the icoHTpcJTbHOM crystallizer determines the melt flow rate at the EMG1 for the zero offset of the workpiece rupture zone and also graphs the temperature shift of the displacement meter at the sensor points. According to these graphs, using the form. 1. Change the ratio of the flow rates of the melt at the solidification front during the EMF to achieve a constant thickness of the crust of the preform at the opposite ends of the mold.

Obtaining a thin crust thickness. At the ends of the criss-plaster, it is possible to reject the adjustment of the drawing speed at small values of the fracture zone and achieve an increase in the homogeneity of the structure of the blanks according to their depth,
