Embodiment Construction
[0015] Such as figure 1 , figure 2 , image 3 As shown, the furnace body for a high-precision atmosphere protection program-controlled tempering furnace includes a furnace shell 1. A furnace mouth 10 with a folded conical head structure is opened on the top of the furnace shell 1. A furnace shell 1 is provided inside the furnace shell 1. Retort 2, the retort 2 is provided with an air guide tube 3, a channel for hot air flow is formed between the air guide tube 3 and the retort 2, and a tube is provided on the retort 2 to facilitate the intake of the protective atmosphere. The air inlet pipe 24, the air inlet pipe 24 passes through the furnace shell 1 and is externally placed on the furnace shell 1, the bottom end of the furnace shell 1 is provided with a second heat insulating layer 12, and the inner circumference wall of the furnace shell 1 is provided with There is a first thermal insulation layer 11, the bottom of the first thermal insulation layer 11 is fixedly connecte...

The invention relates to a furnace body for a high-precision atmosphere protection program-controlled tempering furnace. The furnace body comprises a furnace shell, a furnace pot, a ventilating duct and a heating assembly, wherein a channel convenient for hot air to flow is formed between the ventilating duct and the furnace pot; an air inlet pipe convenient for protective atmosphere to inflow is arranged on the furnace pot; a second thermal insulation layer is arranged at the bottom end of the furnace shell; and a first thermal insulation layer is arranged on the inner wall of the periphery of the furnace shell. The furnace body has the advantages that a furnace opening of the furnace shell is set to be a toriconical head structure, so that mounting and dismantling of the furnace pot are facilitated, the connection is reliable, and the damages to the furnace shell are reduced; through the arrangement of the ventilating duct, flowing of the hot air in the furnace pot is ensured, the balance of the temperature in the furnace pot is ensured, the phenomenon of uneven heating in an existing hearth is avoided, and the tempering efficiency is improved. The protective atmosphere is introduced into the furnace port through the air inlet pipe, so that the air in the furnace pot in a tempering process is effectively improved; and the tempering quality is improved. A hearth is formed by the first thermal insulation layer and the second thermal insulation layer, so that the thermal insulation properties are good; the loss of heat is reduced; and the safety performance is good.
Description
technical field [0001] The invention relates to a furnace body for a high-precision atmosphere protection program-controlled tempering furnace. Background technique [0002] The tempering furnace is used for tempering general metal parts in the air and quenching, annealing and aging heat treatment for aluminum alloy die castings, pistons, aluminum plates and other light alloy parts. The existing tempering furnace body is processed by steel plates. The inner side of the furnace is covered with insulation material. The existing insulation material is basically made of insulation bricks, and the surface of the furnace body is a sealed structure. During the tempering process, the hot air in the furnace has poor flow performance, resulting in different There is a temperature difference in the area, which is not conducive to the heating and tempering of the workpiece, and the furnace is a sealed structure, which cannot handle the exhaust gas generated during the tempering process ...
