Abstract

The utility model discloses a U-type thermal recycling isothermal normalizing furnace, which comprises a furnace body. A left combustion flue and a right combustion flue are arranged in the furnace body and are connected to form a U-shaped structure, a preheating section, a heating section and a heat-insulation section are successively disposed in the left combustion flue, an isothermal section and a slow cooling section are successively disposed in the right combustion flue, and a cold air jetting device is disposed at a connection position of the left combustion flue and the right combustion flue. The U-type thermal recycling isothermal normalizing furnace is reasonable in structure and high in thermal efficiency, and is energy-saving and environment-friendly.

Description

U formula recovery type heat isothermal normalizing stove
Technical field
The utility model relates to a kind of recovery type heat isothermal normalizing stove.
Background technology
In the prior art for the normalizing treatment of metal works (for example carbon steel, steel alloy or cast iron) generally all in stove behind the heat tracing, cooling fast in air or in the air blast thereupon, the emptying in cooling of its workpiece sensible heat is run off, and has energy dissipation major defect such as contaminate environment greatly again thus.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanism reasonable, can make full use of the U formula recovery type heat isothermal normalizing stove of heat energy.
Technical solution of the present utility model is:
A kind of U formula recovery type heat isothermal normalizing stove, it is characterized in that: comprise body of heater, two combustion flues about being provided with in the body of heater, about two combustion flues connect into the U type, be disposed with preheating section, heating zone, holding-zone in the combustion flue of a left side, be disposed with isothermal section and slow cooling section in the right combustion flue, the spray cooling air unit be set in combustion flue junction, the left and right sides.
Described spray cooling air unit comprises the spray ice chest that communicates with the cold wind import, and the air nozzle to combustion flue spray wind is set on the spray ice chest, and the body of heater of combustion flue junction, the left and right sides is provided with blower fan.
The corresponding setting with the slow cooling section of right combustion flue of preheating section of left side combustion flue communicates by heat exchange mechanism between the two.
The utility model is rational in infrastructure, thermo-efficiency height, energy-conserving and environment-protective.
