Description

Изобретение относитс  и металлургии , в частности к нагреву металла под термическую обработку и предназначено дл  применени  в термических печах открытого пламени .The invention also relates to metallurgy, in particular, to the heating of a metal for heat treatment, and is intended for use in open-flame heat-treating furnaces.

Известен способ создани  циркул ции печных газов за счет энергии струи продуктов сгорани , вытекающих со скоростью 200-300 м/сек. Повышение скорости истечени  достигаетс  за счет повышени  дамени , при котором сжигаетс  топливо.. В реактивных горелках оно достигает 1,1-1,2 ата. Процесс окигани  ведут при посто нном давлеши.There is a known method of creating furnace gas circulation due to the energy of the jet of combustion products flowing at a speed of 200-300 m / s. The increase in the flow rate is achieved by increasing the time at which the fuel is burned. In jet burners it reaches 1.1-1.2 at. The process of oxidizing is carried out at constant pressure.

Однако известный способ сложен, дл  осуществлени  высокой степени сжати  топливовоздушной смеси используют громоздкое оборудование (компрессоры, воздуходувки ) , стойкость тошшвосжигающих yCTjpoMcTB, нахо.пдщихс  под непрерывным воздействием высокотемпературных продуктов сгорани , низка , пределы устойчивой работы горелок по избытку воздуха (с However, the known method is complicated; in order to achieve a high degree of compression of the air-fuel mixture, bulky equipment (compressors, blowers) is used;

0,95-1,05) УЗКИ.0.95-1.05) TIPS.

Цель изобретени  - повысить качество термической обработки и улучшить эксплуатационные характеристики печи.The purpose of the invention is to improve the quality of heat treatment and improve the performance of the furnace.

Эта достигаетс  тем, что сжигание топлива осуществл ют при посто нном объеме.This is achieved by burning fuel at a constant volume.

На чертеже представлена схема осуществлени  способа создани  циркул ции в термических печах.The drawing shows the implementation of the method of creating circulation in thermal furnaces.

Печь состоит из камеры I нагрева изделий с крышкой 2 и песочным затвором 3, устройства дл  уст.ановки в печи обрабатываемых изделий, например корзины 4, камеры 5 сгорани , впускного 6 и выпускного 7 клапанов, запального устройства, например свечи 8, распределительных коллекторов 9 и дымового канала 10.The furnace consists of a heating chamber I with parts with a lid 2 and a sand stopper 3, a device for installing processed products in the furnace, for example, a basket 4, a combustion chamber 5, an inlet 6 and an exhaust valve 7, an ignition device, for example a candle 8, distribution manifolds 9 and smoke channel 10.

Предлагаемый способ циркул ции осуществл ют следующим образсж.The proposed circulation method is carried out as follows.

Детали, подвергаемые терлической обработке, загружают в корзину 4 и устанавливают в камере нагрева I. Через клапан 6 в камеParts subjected to thermal processing are loaded into basket 4 and installed in the heating chamber I. Through valve 6 in the chamber
