Description

Известны герметичные камерные печи периодического действи  с восстановительной или нейтральной средой.Sealed periodical kiln furnaces with a reducing or neutral medium are known.

Однако известные печи не обеспечивают необходимой герметизации при загрузке деталей. Значительный подсос воздуха приводит к образованию окисных пленок на издели х, особенно изготовленных из нержавеющих сталей.However, the known furnaces do not provide the necessary sealing when loading parts. Significant air leakage leads to the formation of oxide films on products, especially those made from stainless steels.

Кроме того, в период загрузки изделий в печь и выгрузке их из печи происходит загр знение атмосферы цеха защитными газами.In addition, during the period of loading products into the furnace and unloading them from the furnace, the atmosphere of the shop is polluted with protective gases.

Предлагаема  печь дл  безокислительного нагрева изделий из нержавеющих сталей лищена указанных недостатков, так как в ней применено загрузочное устройство с герметичным затвором. Загрузочное устройство выполнено в виде кармана с крыщкой, открываемой при помощи рычага. Карман снизу перекрываетс  затвором, имеющим форму усеченной пр моугольной пирамиды, и размещен на щтоке с пружиной.The proposed furnace for non-oxidizing heating of stainless steel products is free of these drawbacks, since it uses a hermetic closure loading device. The boot device is made in the form of a pocket with a lid, opened with a lever. The bottom pocket is closed by a shutter having the shape of a truncated rectangular pyramid, and is placed on a spring brush.

На чертеже показана принципиальна  схема камерной печи.The drawing shows a schematic diagram of a chamber furnace.

Загрузочное устройство / печи оборудовано затвором 2, имеющим форму усеченной пирамиды, который размещен на щтоке 5. Крышка 4 при загрузке деталей поднимаетс  рычагом 5 и закрываетс  под воздействием пружины 6, расположенной на щтоке.The loading device / furnace is equipped with a shutter 2 having the shape of a truncated pyramid, which is placed on the rod 5. The lid 4 rises when loading parts with the lever 5 and closes under the influence of the spring 6 located on the rod.

Сначала детали подают в загрузочное устройство через щелевой затвор, образуемый при подъеме крыщки, затем на подающее устройство 7 путем опускани  затвора 2.First, the parts are fed into the loading device through a slit gate formed when the lid is raised, then to the feeding device 7 by lowering the gate 2.

Подающее устройство с детал ми стержнем 9 вручную перемещаетс  в камеру 8 нагрева.A feeding device with parts rod 9 is manually moved into the heating chamber 8.

Предмет изобретени Subject invention

Камерна  печь дл  безокислительного нагрева изделий из нержавеющей стали в защитной газовой среде, отличающа с  тем, что, с целью предупреждени  загр знени  атмосферы цеха защитными газами , выдел ющимис  обычно при загрузке изделий в печь, она снабжена загрузочным устройством, выполненным в виде загрузочного кармана с поднимающейс  при помощи рычага крыщкой и щтока с пружиной, обеспечивающими перекрытие кармана снизу затвором, имеющим форму усеченной пр моугольной пирамиды.A chamber furnace for non-oxidizing heating of stainless steel products in a protective gaseous environment, characterized in that, in order to prevent the atmosphere of the shop from being contaminated with protective gases, usually emitted when the products are loaded into the furnace, it is equipped with a charging device made in the form of a loading pocket with a flap that is raised with the help of a lever and a stem with a spring, which provide for the overlapping of the pocket by the bottom gate having the shape of a truncated rectangular pyramid.
