Description
Известны способы отливки крупногабаритных детален через несколько литниковых каналов с применением заливки металла из нескольких ковшей- Однако они не обеспечивают условий непрерывной кристаллизации металла, в форме.Known methods of casting large-sized details through several gating channels using the pouring of metal from several ladles. However, they do not provide the conditions for continuous crystallization of the metal in the mold.
Особенность описываемого способа получени отливок заключаетс в том, что, с целью повышени заполн емости литейных форм и обеспечени условий непрерывной кристаллизации металла в отливках, заливку металла на всех ступен х производ т при одинаковом гидростатическом напоре.The peculiarity of the described method of producing castings is that, in order to increase the filling capacity of the casting molds and provide conditions for the continuous crystallization of the metal in the castings, the metal is cast at all stages with the same hydrostatic pressure.
По предлагаемому способу заливка металла в формы рассредоточиваетс по высоте отливки, т. е. производитс последовательно по ступен м, начина снизу, причем высота каждой ступени определ етс максимально допустимой высотой падени жидкого металла. Дл осуШ;ествлени способа используют сборные формы с центральным внутренним стержнем, в которых между соседними ступен ми устанавливают сигнальные электрические лампы, показываюш,ие врем перехода при заливке с одной ступени на другую. Подвод металла к каждой ступени производитс через обычные литниковые системы. Заливку жидкого металла в собранные формы производ т из двух или нескольких ковшей. Крупные тонкостенные отливки заливают в наклонно установленные формы.According to the proposed method, the casting of metal into molds is dispersed throughout the height of the casting, i.e. it is carried out sequentially in steps, starting from the bottom, with the height of each step being determined by the maximum allowable height of the fall of the liquid metal. For the implementation of the method, use is made of modular forms with a central inner rod, in which signal electric lamps are installed between adjacent steps, indicating the transition time when pouring from one stage to another. The metal is supplied to each stage through conventional gating systems. Pouring molten metal into assembled forms is made from two or more buckets. Large thin-walled castings are poured into obliquely mounted molds.
Предмет изобретени Subject invention
Способ получени крупногабаритных, преимущественно тонкостенных отливок, путем подвода металла к отливке на разных ступен х, отличающийс тем, что, с целью повышени заполн емости формы металлом и обеспечени условий направленной кристаллизации, металл подаетс « отливке под одинаковым во всех ступен х максимальным гидростатическим напором.The method of obtaining large-sized, predominantly thin-walled castings, by supplying metal to the casting at different stages, characterized in that, in order to increase the mold filling with the metal and provide conditions for directional solidification, the metal is cast under the same maximum hydrostatic pressure in all stages.
