Изобретение относитс к порошковой ме- .теллургии, в частности, к электропечам с защитной газовой средой дл спекани и термообработки MeTannoKepfiMH-iecKHX изделии .The invention relates to powder me- turelgy, in particular, to electric furnaces with protective gaseous medium for sintering and heat treatment of a MeTannoKepfiMH-iccKHX product.
Известна электрюпечь йл термообработки изделий в защитной газовой среде, включающа нагревательную и охладительную камеры , нагреватели, систему загрузки и раз грузки изделий, систему контрол и регули;ровани температуры. Однако така печь отличаетс нестабильностью термического .режима, обусловленной охлаждением печи в направлении газового потока, что сопро- вождаетс снижением качества изделий.The known electric furnace for heat treatment of products in a protective gaseous environment includes heating and cooling chambers, heaters, a system for loading and unloading products, a system for controlling and regulating temperature. However, such a furnace is characterized by the instability of the thermal regime caused by the cooling of the furnace in the direction of the gas flow, which is accompanied by a decrease in the quality of the products.
Предлагаема электропечь отличаетс от известной тем, что, с целью стабилиза:Ции термического режима, она снабжена приспрсоблением дл нагрева газа, вьшол-, Ненным в виде змеевика, ycтaнoвпeнi@Г6гo Iвдоль нагревателей, и экраном, вьшолнен:ным с возможносГью осевого перемещени ;и установленным между нагревательной и охладительной камерами.,The proposed electric furnace differs from that known for the purpose of stabilization: Thermal mode, it is equipped with a gas heating device, a hollow, a coil in the form of a coil, a stand-alone @ H6go I along the heaters, and a shield, complete: with possible axial displacement; installed between the heating and cooling chambers.,

Приспособление дл нагрева газа выполнено в виде i змеевика с :минимальным шагом и минимальной прот женностью пр молинейных участков. Змеевик располагаетс под намоткой нагревателей либо в верхней полости нагрева тельной . камеры,FIG. 1 shows the proposed furnace, a general view; in fig. 2 - section A-Anafig. 17: The heating chamber 1 is a horizontal pipe of rectangular cross section, on which heaters 2 are wound through the insulation, Through: back, wall 3: heaters 1 and valve 4 is fed working gas IB fixture (coil): 5 for preheating the gas. The device for heating the gas is made in the form of a coil with: minimum pitch and minimum length of the straight sections. The coil is located under the winding of the heaters or in the upper cavity of the heater. cameras,
