Description

Известны электропечи с защитной атмосферой дл  термической обработки, имеющие камеру охлаждени , котора  снабжена механизмами с гидравлическими приводами, расположенными в передней и задней камерах печи, обеспечивающих загрузку и выгрузку изделий. Однако, известные электропечи не обеспечивают герметизацию камеры . Кроме того, при их эксплуатации имеютс  потери защитного газа.Electric furnaces with a protective atmosphere for heat treatment are known, having a cooling chamber, which is equipped with mechanisms with hydraulic drives located in the front and rear chambers of the furnace, providing loading and unloading of products. However, the known electric furnaces do not provide sealing chamber. In addition, during their operation there are losses of protective gas.

В предлагаемой печи, с целью устранени  потерь защитного газа , толкатель дл  подъема изделий, поступающих из камеры охлаждени  в переднюю камеру печи, установлен параллельно толкателю - столу, принимающему с него подн тое на один уровень изделие и выдающему изделие в загрузочное отверстие.In the proposed furnace, in order to eliminate the loss of protective gas, the pusher for lifting the products coming from the cooling chamber into the front chamber of the furnace is installed parallel to the pusher — the table receiving the product lifted by one level and issuing the product into the loading opening.

Дл  герметизации камеры, загрузочное отверстие печи снабжено подъемно-опускательным клапаном, обеспечивающим загрузку и выгрузку через одно отверстие.To seal the chamber, the furnace opening is equipped with a lift / lower valve that provides loading and unloading through one hole.

На чертеже изображена схема предлагаемой электропечи, котора  состоит из механизма / загрузки и выгрузки оборудованного колпаком 2, толкател  5, устройства 4 дл  вертикального перемещени  поддонов , загрузочно-выгрузочного стола 5. Печь 6 заключает Е себе герметический футерованный кожух с установленными на поду рельсами. Боковые стенки печного пространства несут на себе спиральные молибденовые нагреватели. Под печью расположена о.хлаждающа  камера/с вод ным охлаждением. Перегрузка поддонов из печи в охлаждающую камеру производитс  при помощи механизма перегрузки 8.The drawing shows a diagram of the proposed electric furnace, which consists of a mechanism / loading and unloading equipped with a cap 2, a pusher 5, a device 4 for vertical movement of pallets, a loading and unloading table 5. The furnace 6 encloses Е itself a sealed lined casing with floor rails installed on the floor. The side walls of the furnace space carry the spiral molybdenum heaters. Under the furnace there is a cooling chamber / with water cooling. The overloading of the pallets from the furnace to the cooling chamber is carried out using the overload mechanism 8.

Работа печи автоматизирована, включа  продувку колпака. Подлежащие спеканию пластины укладываютс  на поддон 9. Поддон сдвигаетс  под колпак, включаетс  кнопка пуска автоматического цикла печи. Поддон накрываетс  колпаком. После продувки пространства под колпаком стол с поддоном опускаетс  гидроцилиндром до уровн  рельс печи и проталкиваетс  в печь длинным ходом толкател . ВышедThe operation of the furnace is automated, including the blowing of the hood. The plates to be sintered are laid on the pallet 9. The pallet is shifted under the hood, the start button of the automatic furnace cycle is turned on. The tray is covered with a cap. After purging the space under the hood, the table with the pallet is lowered by a hydraulic cylinder to the level of the furnace rail and pushed into the furnace by a long stroke of the plunger. Out
