Convection flow type double furnace cover structure using annealing furnace to make furnace temperature uniform

Abstract

The invention discloses a convection flow type double furnace cover structure using an annealing furnace to make furnace temperature uniform, and relates to the technical field of annealing furnaces.The convection flow type double furnace cover structure comprises a fixed seat, a constant-temperature mechanism is fixedly arranged above the fixed seat, and a heat dissipation mechanism is fixedly arranged above the constant-temperature mechanism. According to the convection flow type double furnace cover structure using the annealing furnace to make the furnace temperature uniform, the interiorof the furnace body can be cooled through the mixing of cold air and hot air, so that the working efficiency is effectively improved; through a first one-way valve, the cold air in the working furnace can only be discharged, and in the process of entering the cold air and in the process that the cold air is mixed with the hot air, the effect of convection cooling is achieved; rotating handles arearranged so that the rotating handle can be used to drive threaded rods to rotate; and stop blocks can be driven to rise through the lifting of a lifting plate, and a heat dissipation opening can beopened through the rising of the stop blocks, so that the heat dissipation effect is achieved, the phenomenon that the temperature inside the furnace body is damaged due to high temperature is avoided, and the safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of annealing furnaces, in particular to a convective blowing type double furnace cover structure utilizing uniform furnace temperature of the annealing furnace. Background technique [0002] The heat treatment furnace is divided into annealing furnace, quenching furnace, tempering furnace, normalizing furnace and quenching and tempering furnace. It is mainly used for annealing of large carbon steel and alloy steel parts, tempering of surface hardened parts, stress relief annealing of weldments, aging and other heat treatment processes. The heating methods include electric heating, oil, gas, coal and hot air circulation. The annealing furnace is a new type of heat exchange equipment. The annealing furnace is an energy-saving periodic operation furnace with a super energy-saving structure and a fiber structure, saving 60% of electricity. [0003] Ordinary annealing furnaces generally have either a cooling fan ...
