Изобретение относитс к литейному производству , конкретнее - к процессу получени отливок в металлических формах-кокил х .The invention relates to a foundry, more specifically to a process for producing castings in metal molds.
Известен способ получени чугунных отливок в кокиле, включающий заливку расплава и последующее его охлаждение путем создани зазора между отливкой и формообразующими част ми кокил 1.A known method for producing pig iron castings in a chill mold involves pouring the melt and then cooling it by creating a gap between the casting and the forming parts of the chill mold 1.
Недостатком этого способа вл етс значительна сложность получени равномерного зазора между кокилем и отливкой, а следовательно, и сложность получени однородных свойств по поверхности отливки.The disadvantage of this method is the considerable difficulty in obtaining a uniform gap between the chill mold and the casting, and consequently, the difficulty of obtaining uniform properties along the surface of the casting.
Целью изобретени вл етс повышение качества отливок.The aim of the invention is to improve the quality of castings.
Это достигаетс тем, что после создани зазора отливку привод т во вращательное движение вокруг ее оси симметрии и вращают до полного затвердевани .This is achieved by the fact that after creating the gap, the casting is brought into rotational motion around its axis of symmetry and rotated until it solidifies.
Способ осуществл ют следующим образом .The method is carried out as follows.
ЛСидкий чугун заливают в кокиль с одной или несколькими вертикальными плоскост ми разъема, выдерживают до образовани поверхностной корки, после чего раздвигают части кокил . После создани зазора между отливкой и формообразующими част ми кокил отливку начинают вращать вокруг ее осп симметрии со скоростью 5-60 об/мин до полного затвердевани .The cast iron is poured into a chill mold with one or several vertical planes of the connector, held until a skin crust forms, after which parts of the chill mold are moved apart. After creating a gap between the casting and the molding parts of the chill mold, the casting starts to rotate around its axis of symmetry at a speed of 5-60 rpm until it is completely solidified.
Вращение отливки во врем эвтектического превращени позвол ет равномерно распределить по ее поверхпости вли ние экранировани тепла незавпсимо от разницы в велич1П1ах зазоров и получить отливку с одинаковой структурой и свойствами поворхиосгного сло .The rotation of the casting during the eutectic transformation makes it possible to evenly distribute the heat shielding effect over its surface, regardless of the difference in the gap widths and to obtain the casting with the same structure and properties of the turning layer.
