Description

непрерывной разливки вертикального тина на его грани в зоне вторичного охлаждени подают через форсунки охладитель, ианример воду. При этом охладитель на каждую грань подают только на часть ее поверхности, ограниченную контурами равнобедренного треугольника , основание которого, равное 200 мм, .расположено непосредственно под кристаллизатором , а вершина расположена по оси грани в конце зоны затвердевани на рассто нии 9 м от кристаллизатора.continuous casting of vertical tin on its face in the secondary cooling zone is fed through a nozzle cooler and water. At the same time, a cooler is fed to each face only on a part of its surface bounded by the contours of an isosceles triangle, whose base, equal to 200 mm, is located directly under the crystallizer, and the vertex is located along the axis of the face at the end of the solidification zone at a distance of 9 m from the crystallizer.

При таком распределении охладител по поверхности слитка происходит его равномерное охлаждение, в корочке слитка не возникают термические напр жени , превосход щне допустимые значени , не возникают трещины в слитке, качество его повышаетс .With such a distribution of the cooler over the surface of the ingot, its uniform cooling occurs, thermal stresses do not occur in the crust of the ingot, exceed the permissible values, there are no cracks in the ingot, its quality is improved.

Invention Formula

The cooling method of continuous ingot ingot includes the supply of a cooler to separate parts of the ingot surface. I distinguish it, and so that, in order to reduce thermal stresses and improve the quality of the ingots, the cooler is supplied to a part of the surface of the wide edges of the rectangular ingot limited by the contours of an equilateral trapezium, the larger base of which is located directly under the crystallizer and is equal to the width of the ingot the smaller base is located at the end of the solidification zone of the ingot and is equal to the width of the ingot, reduced by its double thickness, and to the narrow edges of the rectangular ingot and the edges of the square ingot, the cooler is served for an hour s surface bounded by contours of an isosceles triangle, the base of which is located directly below the mold and is equal to the width of the facets, and a vertex positioned in the end zone of the ingot solidification.
