800KG Gas Fired Aluminum Alloy Holding Furnace For Steel Melting CE

800KG Gas Fired Aluminum alloy holding furnace

1. aluminum alloy pool type gas holding furnace

Pool type gas aluminum holding furnace is mainly suitable for heat preservation

of non-ferrous metal solution, which can be used in die casting machine,

centrifugal casting, gravity casting, precision casting and other processes.

The product consists of furnace body, burning system and electrical control

system.A flat flame combustion system is installed on the top of the furnace body,

which directly radiates the aluminum alloy liquid level in the molten pool,

with high thermal efficiency and convenient maintenance, cleaning and movement.

The gas pool type aluminum holding furnace is a kind of aluminum alloy

holding furnace which can carry out heat recovery and limit the pursuit

of energy saving.High quality imported flat flame burner is adopted, with

large flame radiation area and high thermal efficiency. The temperature of

aluminum liquid can be controlled within ± 3 ℃, and the oxygen content in

the furnace atmosphere is less than 5%, which can effectively prevent the

generation of oxide in the furnace. Due to its unique thermal insulation structure,

it can effectively reduce the surface heat dissipation, reduce the surrounding

temperature and improve the thermal efficiency.

The furnace lining is made of high-strength non stick aluminum refractory

castable (Allied Mineral), with a service life of more than 5 years (three-year warranty).

Adopt special combustion system and combustion supporting fan to realize

low noise work.

2. This aluminum holding furnace is designed for the purpose of

heat preservation of aluminum alloy according to the requirements of our company.

It has the following technical parameters.

3. furnace structure

3.1 steel structure:

The furnace shell is made of steel plate and section steel and the material

around the furnace door is cast iron.The whole furnace has lifting function,

which is convenient for matching with the equipment.

3.2 Lining composition:

The part of the molten pool is made of silicon carbide nitride brick, which

has the characteristics of high strength, non stick aluminum, long service

life, etc.Heat preservation nano insulation layer shall be used at the top and

upper end of furnace wall. The temperature rise of furnace wall is less than 25 ℃.

3.3 Combustion system:

3.3.1The imported gas burner is selected. The operation and maintenance

are simple and the service life is long. At the same time, it has temperature

control, automatic ignition and flame eye monitoring. When the set temperature

is reached, the burner stops burning. When the temperature in the furnace is

lower than the set temperature limit, the burner enters the combustion port to

ignite and burn automatically. After the operation preparation of the aluminum

holding furnace is completed, the air blowing is carried out first. When the

flame is detected by the flame detection rod, the burner will automatically

and gradually enter the high combustion state. Meanwhile, the flame detection

rod always monitors the combustion state of the burner.

3.3.2 The safety system of the holding furnace can cut off the main burner

and ignition burner immediately and cut off the fuel supply in case of incomplete

combustion or extinction of the burner. The interlock device is set between the

pressure switches of the fuel and combustion air pipelines, so that the shut-off

valve of the fuel supply can be closed through the response of the interlock

device in case of any abnormal combustion conditions.According to the temperature

of the aluminum liquid in the holding furnace, the temperature control is to

automatically adjust the rotation speed of the combustion fan through the

frequency converter of the combustion fan, so as to adjust the combustion

quantity of the burner. The method is PID regulation.Set the upper temperature

limit by heating the atmosphere temperature in the cover to control the atmosphere temperature.

3.4 Main components of combustion system

3.5.Low voltage electric adopts components of Schneider and Chint brand.

The touch screen is Siemens.

4. temperature control

4.1 Automatic temperature control flame switch, over temperature alarm,

flameout protection, etc

4.2 aluminum temperature control

4.3 furnace temperature control

4.4 safety device and automatic control system:

When the preparation of the furnace is finished, first use the blower to

purge the furnace after the switch is turned on, set the control temperature,

at the same time, turn on the solenoid valve of the gas pipeline, inject the

gas into the furnace, and ignite automatically.

5. scope of user works:

5.1 the gas pipeline shall be connected to the side of the furnace body as required.

5.2 Electrical wiring works. Wire from the control cabinet to the furnace body is to

be provided by our company. (within 5m) The power supply is 380V ± 10%, 50Hz.

5.3 furnace positioning work (also coordinated by both parties).
