Description
Ходную камеру. Днище опоки снабжено отверсти ми дл равномерного прохода газообразных продуктов. В качестве поддерживающей решетки служит сетка с сечением чейки в свету 0,1x0,1 мм, которую укладывают на днище оноки перед формовкой. Заливка формы производитс низкоуглеродистой сталью. Были получены отливки но газифицируемым модел м в форме из ферромагнитного сыпучего материала ДСК-05 при поступлении воздуха в полость формы после заливки в течение 1,3, 5, 7, 10 мин Юл на 1 г модели, атакл :е контрольные отливки при обычном способе заливки. Исследование микроструктуры отливок по известному и предлагаемому способам показывает, что микроструктура поверхностного сло контрольной отливки науглерожена на глубину 0,3 мм до свободного цементита, 1)асположенного в виде разорванной сетки по границам зерен. В отливке, полученной нриThe running camera. The bottom of the flask is provided with holes for uniform passage of gaseous products. A grid with a cell cross section of 0.1x0.1 mm in the light, which is placed on the bottom of the onoki before forming, serves as a supporting grid. The die cast is produced by low carbon steel. Were obtained by casting but gasifiable models in the form of ferromagnetic bulk material DSK-05 when air entered the mold cavity after pouring for 1.3, 5, 7, 10 min Yul per 1 g of model, attack: e control castings with the usual method fill. The study of the microstructure of castings according to the known and proposed methods shows that the microstructure of the surface layer of the control casting is carburized to a depth of 0.3 mm to free cementite, 1) laid out in the form of a broken mesh along the grain boundaries. In casting
подаче воздуха 10 л на 1 г у1оделн в течение 3-5 мин носле заливки, науглероженный слой отсутствует.air supply of 10 l per 1 g is one for 3-5 minutes during pouring, there is no carburized layer.
