Gas Fired Bogie Hearth Furnace Factory

Main technical parameters and equipment

steel structure

Steel structure welded from shape steel, steel plate, lightweight and reliable.

The furnace’s door has a peephole, covering the entire field of vision peephole furnace in all areas, in order to facilitate the operator to understand the situation in the furnace.

Furnace lining

Furnace lining using fiber blanket folded piece (LYGX-289), low thermal conductivity, heat capacity, excellent thermal insulation properties. Lining structure is the whole fiber structure, the lining thickness is 300mm, stainless steel anchors multi-point positioning, structure solid, surface and coated with high temperature curing agent.

The maximum temperature at 1200℃, the furnace side surface temperature ≤45℃, roof surface temperature≤55℃.

The lift door of furnace

Using mechanical lift gate furnace’s door: furnace’s door welded from steel plate and steel frame structure, all-fiber insulation collapse block structure, fixed anchors which located on the door peephole. Enhance the use of electric door complete with mechanical power (preparation of moving), manual control by the central control cabinet, door lift moving speed of about 4-5m / min.

Trolley

trolley is carrying workpiece heating and transport platform,Our furnace trolley by heavy car wheels,actuating device,Enough strength of the steel structure of the frame and refractory insulation materials.

The trolley walk by electric motors+reduction gears+Chain drive form to cooperate to complete.

combustion system

1,centrifugal fan

*centrifugal fan adopt 9-19series,Is a single stage axial single suction type centrifugal fan,Low noise, small flow rate, air pressure as a beginning.

2,Burning pipeline (including air supply, gas supply system

*  Chooses the pipeline fittings and valves of reliable performance, safe operation, convenient maintenance,Choose domestic or imported famous brand products. Larger valves equipped with simple rings, for lifting.

. control system

* The control system with manual/automatic control function.

Electric control cabinet

* Burners and ignition controller transformer installed in the control cabinet,there isa switch on the door.Setting mechanical action manual control console furnace before.

1)Control function description

2)The heating zone temperature control

1. Adopt pulse control

2. Gas flow through the air-fuel ratio valve adjusted according to the follow-up mode,Ensure reasonable air-fuel ratio (if eventually adopts double electromagnetic control method, proportional valve is cancelled).

3. Can be set temperature curve,with more curves storage function,Can realize heating, constant temperature control function.

4. If the various points to be measured temperature than set value,System will alarm in time.

2)Gas main pipe pressure

Manager should set the regulator valve,Automatically adjust the gas main pipe pressure,Make its stability within a given range.

Low pressure gas main chain alarm function.

Trolley furnace electric drive and control

Electrical control system including the furnace area within the scope of the electrical control and low voltage power distribution.Furnace area are all made of low voltage (380 v / 220 vac).

1)combustion fan  ON/OFF control

2)Pallet, oven door interlock, sealing equipment

3)loading:trolley in-close the furnace door-seal

4)unloading:open the seal-open the furnace door-out of trolley

5)Distribution and control combustion system;

6)Purging procedure:

Open the fan automatically after enter the purging process,At this point do not allow the ignition control system,Purging can meet the ignition conditions after the completion of the implementation of the ignition and into the temperature control.

Cable connection arrangement

*According to the equipment and customer site conditions;

Paint

* Can be designed according to customer requirements;

Supply scope

Company profile
