Description

Известны формы дл  отливки глуходонных изложниц с использованием центрального земл ного стержн .Molds are known for casting coreless molds using a central earth rod.

Особенность предлагаемой формы заключаетс  в том, что стержень в верхней части снабжен металлической надставкой. Такое выполнение формы обеспечивает повышение качества отливаемых изложниц.A feature of the proposed form is that the rod in the upper part is provided with a metal extension. This embodiment of the form provides improved quality cast molds.

На чертеже изображена схема предлагаемой формы.The drawing shows a diagram of the proposed form.

Форма имеет центральный земл ной стержень /, в верхней части которого расположена металлическа  надставка 2.The shape has a central earth rod /, in the upper part of which there is a metal extension 2.

После набивки стержн  состаном и установки надставки стержень окрашивают обычным способом, а затем сушат. При заливке металла в форму и соприкосновении его с металлической надставкой он приобретает мелкозернистую перлито-феррптную структуру, поэтому донна  часть изложницы оказываетс  устойчивой к разгару. Остальна  часть изложницы может иметь феррито-перлитную структуру, предотвращающую возможность образовани  трещин на ее стенках. Таким образом, при одном и том же химическом составе металла различные части цзложницы имеют разную структуру в соответствии с услови ми ее работыПредмет изобретени After the core is packed, the stem is installed and the extension is installed. The core is painted in the usual way and then dried. When metal is poured into the mold and in contact with the metal extension, it acquires a fine-grained perlite-ferrite structure, so the bottom part of the mold is resistant to heat. The remainder of the mold may have a ferritic-pearlitic structure preventing the possibility of cracking on its walls. Thus, with the same chemical composition of the metal, the different parts of the companion have a different structure in accordance with the conditions of its operation.

Форма дл  отливки глуходонных изложниц с использованием земл ного центрального стержн , отличающа с  тем, что, с целью повышени  качества отлин-аемых изложниц, стержень снабжен в верхней части металлической надставкой.A mold for casting dead-cast ingot molds using an earth core rod, characterized in that, in order to improve the quality of the cuttable molds, the core is provided with a metal extension in the upper part.
