The cooling device crystallizer HORIZONTAL continuous casting machines from ferrous metals and alloys

摘要

The invention relates to metallurgy, in particular to continuous and semi-continuous casting of billets made of nonferrous metals and alloys in horizontal machines with a volume of the crucible is not more than 12000 cm ³ and a melt temperature of not more than 1500 ° C.; The cooling device of a graphite mold of horizontal continuous casting machine of the non-ferrous metal and alloys with a volume of the crucible is not more than 12000 cm ³ and a melt temperature of not more than 1500 ° C, made of upper and lower portions disposed on the mold by the metal yield, according to the utility model , each part comprises two cooling circuits, each circuit comprises a channel for supplying a cooling fluid, made in the central part of the cooling device, along the direction Navigating Nia metal cross channel relative to the direction of metal movement, located on the side of the metal entry into the mold with a plug and a channel for discharging cooling liquid, made by the lateral surface of the cooling device at an angle to the direction of metal flow, forming in this area tapering contour, and channels for supplying coolant to the bottom of the cooling unit fitted with valves at the inlet of the coolant. The angle between the channels for discharging the cooling liquid and the direction of movement of the metal is 10-15 ° C.; The technical result - improving the quality of the ingot due to the more uniform structure in its thickness and width.
