Изобретение относится к литейному производству. Целью изобретения является обеспечение высококачественных плотных отливок и повышение выхода годного литья. Литейная форма снабжена вкладышами с экзотермическим, охлаждающим, поверхностнолегирующим и термитным материалом. Вкладыши изготавливаются из картона, сохраняющего свою форму в процессе формовки. Вкладыши с экзотермическим и термитным материалом устанавливаются в уступ прибыли. Вкладыши с термитным и поверхностнолегирующим материалом размещаются в полости отливки и стержнях. Форма вкладышей может быть прямоугольной, цилиндрической и др. Для повышения температуростойкости вкладыши из картона могут быть пропитаны жидким стеклом.The invention relates to foundry. The aim of the invention is to provide high-quality dense castings and increase the yield of suitable casting. The mold is provided with liners with exothermic, cooling, surface-alloying and thermite materials. Liners are made of cardboard, which retains its shape during the molding process. Liners with exothermic and thermite material are installed in the ledge of profit. Inserts with thermite and surface alloying material are placed in the cavity of the casting and cores. The shape of the liners can be rectangular, cylindrical, etc. To increase the temperature resistance of the liners made of cardboard can be soaked in liquid glass.
