Structure Of Annealing Furnace



Structure of annealing furnace

Heat treatment furnace for annealing furnace, quenching furnace, tempering furnace, normalizing furnace, hardening and tempering furnace, mainly used for large carbon steel, alloy steel parts surface quenching tempering; annealing; welding stress relief annealing and aging heat treatment process. The heating modes include electric heating, fuel oil, gas, coal combustion and hot air circulation. The annealing furnace is a new type of heat exchange equipment. Annealing furnace is energy-saving cycle operation furnace, super energy-saving structure, adopt fiber structure, save electricity 60%.

The frame of the annealing furnace is welded by various types of steel, the outer frame is made of channel steel, the main plate is cold plate, and the trolley is made of channel steel. The bottom plate and front and back end plate adopt middle plate.

The driving part of the annealing furnace is that the trolley is driven by an electric motor and a reducer is driven by a chain of driving wheels at the front end through a chain. The door furnace is driven by a worm gear reducer and an electric motor.

Sealing: the labyrinth sealing structure between the car and the furnace body is provided, and the automatic sealing device for the sand sealing knife is arranged on both sides of the trolley. The sealing of the furnace door is made of roller type compression and spring pressing mechanism. The furnace body is made of high quality refractory brick structure to ensure the sealing property of the furnace. The high voltage aluminum brick is used for the compression part of the trolley, and the lower part is filled with insulating bricks for insulation.

The annealing furnace combustion system in furnace are respectively arranged at both sides of only a few burning in the furnace, heat flow reciprocating cycle, ensure the temperature uniformity. Automatic and semi-automatic type may be selected as required.

Exhaust gas preheating device in furnace is arranged on the upper end of the exhaust gas preheating device, flue gas in the furnace through the preheater, the fan into the cold air is preheated by the pipeline sent to the burner combustion, and a manual butterfly valve installed in the outlet, the valve can adjust the pressure in the furnace. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, power, shipbuilding, paper making, mining, medicine, central heating and other industrial sectors heating, cooling, condensation, evaporation and other processes.
