Gas Furnace for Melting Aluminum Features and Applications


The gas furnace for melting aluminum scrap is an energy-saving aluminum melting furnace.

It can better meet the requirements of strict alloy composition, large single furnace capacity, and discontinuous production in the process of smelting aluminum and aluminum alloys.

It improves working conditions and improves production efficiency.

When using a gas furnace for melting aluminum scrap, daily maintenance is also an important link that cannot be ignored.

Regular maintenance of equipment can not only improve work efficiency but also prolong its service life.

 

What are the characteristics of the gas furnace for melting aluminum scrap?

 

1. Small environmental pollution


With natural gas as fuel, the combustion products are mainly water and CO2, which can be directly discharged into the atmosphere.

 

2. High thermal efficiency and low operating cost


The lining of the gas-fired waste aluminum smelting furnace adopts a full-fiber structure, which improves the thermal insulation performance of the furnace body, saves energy, and reduces production costs.

 

3. The heat is reused, and the energy-saving effect is good.


The gas-fired scrap aluminum smelting furnace adopts a multiple heat flow channel system design, fully develops and utilizes the energy generated by the burner, and greatly improves thermal work efficiency.

 

4. Automatically adjust the air pressure in the furnace


The level of air pressure in the furnace has a great influence on the use effect of the heating furnace.

 

When the pressure in the furnace is high, the furnace gas will rush out of the sealed gaps of the furnace body to form airflow erosion, which will have a great impact on the furnace door and furnace bottom sealed with fiber materials.

 

At the same time, the high-temperature airflow will also affect the surrounding environment of the furnace body and control devices. When the furnace pressure is low, the cold air is sucked from the sealing gap, which will not only increase the oxidation of the workpiece but also causes the high temperature in the furnace to be quickly drawn out by the negative pressure, resulting in a waste of fuel.


Gas furnace for melting aluminum scrap can smelt materials


1. A single type of scrap aluminum


This kind of waste aluminum is generally a certain type of waste parts, such as automobile reducer casings, pistons of internal combustion engines, front and rear bumpers of automobiles, wheels, aluminum doors, windows, etc. These materials can be put directly into the furnace for smelting.

 

2. Scattered scrap aluminum material


Such waste aluminum materials are represented by pop cans, aluminum wire, etc. Briquetting is required before smelting.

 

3. Mixed aluminum scrap


This kind of waste miscellaneous aluminum has a complex composition and different physical shapes. In addition to scrap aluminum, it also contains scrap steel, scrap iron, scrap lead, scrap zinc, and other metals and waste rubber, waste wood, waste plastics, and non-metallic materials such as stones. This type of waste has a complex composition and a small amount of material is relatively large. Such scrap is pre-sorted before smelting, in which steel scrap and other impurities are manually picked out.


How to clean up the waste slag in the furnace?

 

Cleaning up waste slag needs to be carried out when the gas-fired aluminum melting furnace is working normally. After letting go of the molten aluminum, use a round steel with a length of 3m and a diameter of 30mm-40mm to hit the place with carbon deposits in the furnace from the slag opening. The carbon deposits will fall off one by one, and they can be cleaned up in 1-2 hours. For the slag removal of the scrap aluminum smelting furnace in the production process, one or two times a day is enough. Maintaining this frequency can reduce the failure rate and improve the service life of the scrap aluminum smelting furnace.
