Description
Изобретение относитс к металпургии и может быть использова:но рри получении nojttax слитков дл кузнечно-прессового производства. По основному авт. св. №276111 известно устройство дл отлиЬки палых елиткбв, состо щее из разливочного ковша, промежуточного ковша , опорной рамы изложницы и охфавки , выполненной в виде трубы из металла, состав.которого соответствует составу внутренней поверхности слитка, внутри трубы с зазором установлен стержень-холодильник 1. The invention relates to metalpurgy and can be used: but to obtain nojttax ingots for forging and pressing production. According to the main author. St. No. 2761111, a device for casting fallen elitskb is known, consisting of a pouring ladle, an intermediate ladle, a mold base frame and an ohfvka made in the form of a pipe made of metal, the composition of which corresponds to the composition of the inner surface of the ingot, a cooler 1 is installed inside the pipe with a gap.
i Однако из-за незначительной теплпередачи излучением через воздуш;ный зазор возможно подплавление оправки , уход металла из полости формы и сваривание его со стержнемxoлoдильникo л . При заливке слитков большой Macctk возможно заклинивание стержн -холодильника при усадке металла и образование трещин на внутренней полости слитка.i However, due to insignificant heat transfer by radiation through an air gap, the mandrel may melt, the metal leaves the mold cavity and is welded to the rod of the l-holder. When casting large Macctk ingots, it is possible that the core of the fridge will jam when the metal shrinks and cracks form on the internal cavity of the ingot.
Цель изобретени - повышение качества полых слитков за счет увеличени теплотвода от внутренней полости слитка.The purpose of the invention is to improve the quality of hollow ingots by increasing the heat supply from the internal cavity of the ingot.
Поставленна цель достигаетс тем, что устройство снабжено вставкой трубчатсий формы, размещенной в зазоре между стенкгиед оправки и стержн -холодильника и выполнен .ной из двух частей - нижней из высокотеплопроводного материала, ;температура плавлени которого ниже .температуры затвердевани слитка, The goal is achieved by the fact that the device is equipped with an insert of tubular form placed in the gap between the wall of the mandrel and the rod of the refrigerator and is made of two parts - the bottom of a highly heat-conducting material, the melting point of which is lower than the solidification temperature of the ingot,
O на высоту тела слитка, и верхней из огнеупорного материала на вы- . ;соту прибыльной части слитка.O to the height of the ingot body, and the upper of the refractory material to you-. ; honeycomb profitable part of the ingot.
В процессе заливки и кристаллизации слитка тепло перегрева и In the process of casting and crystallization of the ingot, heat is overheated and
5 кристаллизации заливаемого металла используетс дл расплавлени вставки и передачи его стержню-холодильнику .5, the cast metal crystallization is used to melt the insert and transfer it to the cooler rod.
. Кс лбинированна трубчата встав0 ка состоит из двух частей. С целью быстрейшего отвода тепла и затвердевани тела слитка нйжн часть на высоту тела состоит из высокотеплопроводного материала, имеющего темпе5 ратуру плавлени ниже температуры . затвердевани слитка, например свинца . Верхн часть выполнена из огнеупорного материала, например магнезита, с целью обеспечени на0 правленного затвердевани слитка. Kc pipe is inserted into two pieces. In order to quickly heat and solidify the body, the ingot nigh part to the height of the body consists of a highly heat-conducting material having a melting point below the temperature. solidification of the ingot, for example lead. The upper part is made of a refractory material, for example magnesite, in order to ensure the directional solidification of the ingot.
