Abstract
The utility model discloses a heat recovery type continuous isothermal furnace, which comprises a furnace body; wherein, an upper combustion flue and a lower combustion flue are arranged in the furnace body; a preheating section is arranged at the front end of the upper combustion flue; a heating and holding section is arranged at the rear end of the upper combustion flue; a rapid cooling section, an isothermal section and a slow cooling section are arranged in section in the lower combustion flue; both the upper and the lower combustion flues are provided with a foraminous conveyer. The utility model has simple structure, is capable of preheating the newly fed workpieces fully using the thermal energy discharged in cooling the metal, the thermal utilization rate is high, the foraminous conveyer is not directly exposed outside the furnace, thereby, the heat loss in the furnace cycle is reduced.
Description
Technical field:
The utility model relates to a kind of isothermal normalizing treatment unit of metal parts.
Background technology:
Normalizing and dry quenching for metal works (for example grey cast iron, high chromium steel ball) in the prior art are handled, generally in stove behind the heat tracing, cool off fast in air, its workpiece heat energy runs off after cooling, has defectives such as energy dissipation is big, seriously polluted thus.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can make full use of the recovery type heat continuous isothermal normalizing electric furnace of heat energy.
Technical solution of the present utility model is:
A kind of recovery type heat continuous isothermal normalizing furnace, it is characterized in that: comprise body of heater, double-deck combustion flue up and down is set in the body of heater, upper strata combustion flue front end is a preheating section, the back segment of upper strata combustion flue is the heat tracing section, lower floor's combustion flue is followed successively by fast cold section, isothermal section, slow cooling section, in the upper and lower layer combustion flue foraminous conveyer is set.
The slow cooling section of the preheating section of upper strata combustion flue and lower floor's combustion flue is oppositely arranged, and is the hot switching path form between the slow cooling section of the preheating section of upper strata combustion flue and lower floor's combustion flue.
First foraminous conveyer is set in the last combustion flue, second, third foraminous conveyer is set in lower floor's combustion flue, and second, third foraminous conveyer is in the isothermal section handing-over of lower floor's combustion flue.
Fast cold section at lower floor's combustion flue is provided with strong spray cooler.Guipure end in the combustion flue of upper strata is provided with the blanking slideway mouth that material slips into guipure in lower floor's combustion flue.
The utility model is rational in infrastructure, can make full use of the heat energy that metal cools emits and make preheating usefulness for the workpiece that newly advances stove, and heat utilization efficiency height, guipure directly are not exposed at outside the stove, and the stove internal recycle has reduced thermosteresis thus.
