Изобретение относитс к области литейного производства, в частности к технологическим пробам дл определени склонности металла к образованию гор чих трещин при кристаллизапии и охлаждении отливки.The invention relates to the field of foundry, in particular, to technological samples for determining the tendency of a metal to form hot cracks during crystallization and cooling of a casting.
Известна проба дл контрол отливок, выполненна из пластины одинаковой толщины П-образного сечени .A known sample for controlling castings, made of a plate of uniform thickness of the U-shaped cross section.
Однако дл точного определени оптимальной длины заготовки требуетс больщое количество типоразмеров таких проб.However, a large number of sample sizes of such samples is required to accurately determine the optimal length of the workpiece.
Предложенна проба отличаетс тем, что пластина выполнена в виде клина и снабл еиа по оси симметрии с внутренней стороны П-образного сечени ребром.The proposed sample is characterized in that the plate is made in the form of a wedge and provided it with an axis along the axis of symmetry from the inner side of the U-shaped section.
Это уменьшает типоразмеры проб и создает возможность управлени развитием гор чей трещины.This reduces sample sizes and makes it possible to control the development of a hot crack.
На фиг. 1 изображена металлическа форма дл пробы, общий вид; на фиг. 2 - сечение по А-А на фиг. 1.FIG. 1 shows the metal mold for the sample, general view; in fig. 2 is a section along A-A in FIG. one.
В неподатливой форме литейна усадка металла в данной пробе в температурном интервале хрупкости практически отсутствует, в результате чего в середине верхней части пробы образуетс и развиваетс гор ча трещина .In the intractable form of the casting metal shrinkage in this sample in the temperature range of brittleness is practically absent, resulting in a hot crack in the middle of the upper part of the sample.
Трещнноустойчивость металла измер ют длиной П-образного сечени пробы в том месте , где кончаетс трещина.The crack resistance of the metal is measured by the length of the U-shaped cross-section of the sample in the place where the crack ends.
