(54) ИЗЛОЖНИЦА ДЛЯ КРУГЛЫХ СЛИТКОВ в изложнице перераспределение массы по высоте достигают утолщением стенки в верхней зоне ., На фиг. I изображена изложница дл круглого слитка, в которой дл усилени верхнего торца отношение толпшны стенки , изложницы к радиусу слитка в верхнем торце равно О,65, наружна поверхность выполнена в форме двух усеченных конусов . Высота верхнего конуса0,30 высоты ИЗЛОЖ1ШЦЫ. Конусность верхней час ти 30 , конусность нижней части - 18 На фиг. 2 изображена изложница дл круглого слитка, в которой дл увеличени долговечности и улучшени устойчивости конусность верхней части ДО О,4О высоты изложницы 12°, конусность нижней части 0,4. Отношение толщины стен ки изложницы 5 к внутреннему радиусу изложницы R в верхнем торце О,5О-О,8О. Наружна поверхность изложницы выполн етс в форме двух усеченных конусов . Конусность верхней части наружной поверхности на высоте О,2-О,9 высоты изложницы 4-70, а конусность нижней части 0,4-20 . Конусность верхней час 214 ти изложницы превышает конусность нижней части в 1,5-ЗО раз. Соотношение , масс изложницы и слитка 1,1-2,50. Снижение отношени толщины стенки изложницы к радиусу слитка в верхнем торце изложницы ниже0,5О и уменьшение конусности верхней части наружной поверхности менее 4 приводит к ухудшению стойкости из-за ослаблега верхнего торца. Увеличение соотношени () сверх 0,80 и нконусности сверх 7О° не целесообразно из-за повыщени массы излоношцы. Увеличение высоты верхнего конуса изложницы сверх 0,90 ухудшает устойчивость изложницы, а уменьшение ниже О,2 ослабл ет верхний торец и ухудшает стойкость изложницы. Уменьшение соотношени ИгСниже О,9О приводит к ухудшению стойкости изложниц дл высоколегированных сталей и сплавов из-за потери прочности тонкими стенками, а увеличение сверх 2,5О - не экономично. Параметры изложниц и их стойкость приведены в таблице.(54) DEPOSIT FOR ROUND INGOTS in the mold, the redistribution of the mass in height reaches a wall thickening in the upper zone. In FIG. I shows a mold for a round ingot, in which, to reinforce the upper end, the ratio of the massive walls, the mold to the ingot radius at the upper end is O, 65, the outer surface is made in the form of two truncated cones. The height of the upper cone is 0.30 of height. The taper of the upper part is 30, the taper of the lower part is 18. In FIG. Figure 2 shows a mold for a round ingot, in which, to increase durability and improve stability, the taper of the upper part TO 0, 4O of the height of the mold is 12 °, the taper of the lower part is 0.4. The ratio of the wall thickness of the mold is 5 to the inner radius of the mold R at the upper end O, 5O-O, 8O. The outer surface of the mold is in the form of two truncated cones. The taper of the upper part of the outer surface at a height of 0, 2-O, 9 of the height of the mold 4-70, and the taper of the lower part of 0.4-20. The taper of the upper hour of the mold is greater than the taper of the lower part by a factor of 1.5 to 30. The ratio of the mass of the mold and ingot 1.1-2.50. A decrease in the ratio of the wall thickness of the ingot mold to the ingot radius at the upper end of the ingot mold below 0.5 O and a decrease in the taper of the upper part of the outer surface of less than 4 leads to a deterioration in durability due to the weaker upper end. An increase in the ratio () in excess of 0.80 and an inclination in excess of 7 ° is not advisable because of the increase in the mass of the craters. An increase in the height of the upper cone of the mold above 0.90 impairs the stability of the mold, and a decrease below 0,2 weakens the upper end and impairs the stability of the mold. A decrease in the ratio of IgSnie O, 9O leads to a deterioration of the stability of the molds for high alloy steels and alloys due to loss of strength by thin walls, and an increase in excess of 2.5O is not economical. The parameters of the molds and their durability are shown in the table.
