Изобретение относитс  к области дуговой вакуумной плавки и отливки металлов.This invention relates to the field of vacuum arc melting and metal casting.

По основному авт.св. N 359970 известна вакуумна  дугова  печь дл  плавки и лить  металлов , состо ща  из плавильной камеры с шиберным э твором и плавильным тиглем, заливочной камеры, перемещаемой в горизонтальном направлении , и центробежной машины. Заливочна  камера выполнена в виде обечайки с опорами дл  стола, свободно устанавливаемого на телескопическом валу центробежной машины, снабженном дополнительным приводом вертикального перем«1це1ш .According to the main auth. N 359970 is a well-known vacuum arc furnace for melting and casting metals, consisting of a melting chamber with a slide valve and a melting crucible, a casting chamber moved in a horizontal direction, and a centrifugal machine. The casting chamber is made in the form of a shell with supports for the table, freely mounted on the telescopic shaft of a centrifugal machine, equipped with an additional drive of the vertical re1c1sh.

Целью предложенного устройства  вл етс  повьгшение производительности установки в целомThe purpose of the proposed device is to improve the performance of the plant as a whole.

Это достигаетс  за счет усоверцюнствовани  заливочной камеры, в которой встрюены вакуумные шиберные затворы с клапанами, соединенными с механизмом перемещени .This is achieved by improving the filling chamber, in which the vacuum slide valves are fitted with valves connected to the movement mechanism.

На чертеже показано предложенное устройство .The drawing shows the proposed device.

Заливочна  камера 1 снабжена двум  шиберными затворами 2 и 3, установленными в верхней и нижней часта камеры. Шнберные затворы имеют клшаны 4 и 5, перекрывающие технологические проемы и соединенные с механизмом 6 перемещени .Filling chamber 1 is equipped with two slide gates 2 and 3 installed in the upper and lower parts of the chamber. Connector closures have valves 4 and 5, blocking technological openings and connected to the movement mechanism 6.

,Внутри камеры 1 закреплены три установочных пaлы a-упора 7 дл  точной установки стола 8 с формой., Inside the chamber 1, there are three mounting pads of the a-stop 7 fixed for the exact installation of the table 8 with the form.

Герметизаци  камеры осуществл етс  поджаткем резиновых уплотнений 9 к клапанам 4, 5 за счет подаод сжатого воздуха в канавки резинового уплотнени  или поджатием клапанов эксцентриками к резиновым уплотнени м.The sealing of the chamber is carried out by preloading the rubber seals 9 to the valves 4, 5 by supplying compressed air to the grooves of the rubber seals or preloading the valves with eccentrics to the rubber seals.

Перемещение клапанов по направл ющим фланца осуществл ют с помощью механизма 6.The movement of the valves along the flange guides is carried out by means of mechanism 6.

Литейнал камера точно фиксируетс  относительно плавильной камеры с помощью щтырей 10. В боковых стенках литейной камеры встроены три смотровые окна 11, предназначенные дл  йизуальнОго осмотра внутреннего пространства камеры.The casting chamber is accurately fixed relative to the melting chamber with the help of shtyry 10. Three viewing windows 11 are built in the side walls of the casting chamber, which are intended for a visual inspection of the internal space of the chamber.

После заливки металла в формы, установленные на столе 8, происходат опускание стола на 25 пальцы-упоры 7 и вьшод шпиндел  центробежнойAfter pouring the metal into the molds mounted on the table 8, the table is lowered by 25 fingers-stops 7 and the spindle centrifugal is shown
