Auxiliary Equipment

Auxiliary Equipment for Aluminium

Loading machines


At GHI, we have designed a series of machines for optimising the operation of furnaces and equipment.


Operation

These machines have a hydraulic power unit that supplies the drive fluid for load elevation, lowering and gripping. They work automatically, but can also be operated manually.
To monitor loading and unloading operations, the machines are equipped with video cameras which are of even greater usefulness when multiple furnaces are in operation.

Value proposition


Doors open for a shorter time.

Door lintel and threshold refractory linings last longer.

Greater efficiency of smelter, since there is less heat loss.

Improved worker safety, since the process is automated.

De-drossing machines


The quality of the metal obtained from the second melting operation depends on the cleanliness of the smelter and lack of dross in casting. Dross is removed by machines specifically for this purpose.


Operation

They have a movement trolley which enables them to be positioned anywhere along the width of the door opening. They have a second mechanism which enables a cleaning rabble to be inserted inside the furnace chamber, and cooling systems to prevent arm warping.

Depending on the application required, they may be floor or overhead-mounted, or move along embedded rails.

Value proposition


Optimum bath cleanliness.

High quality metal obtained.

Furnace refractory linings last longer.

Transport ladles


As an alternative to ingot supply, we can offer you ladles for transporting molten aluminium. These ladles are insulated, so transport time can be several hours without the metal requiring reheating.


Operation

Aluminium is supplied in 6-tonne capacity closed ladles.


Value proposition


Improved energy consumption.

Less loss of metal.

Metal does not require reheating.

A second mechanism allows for a cleaning wire to be inserted into the entire chamber. It includes a cooling system which prevents the wire mast from warping.

Porous plugs


By means of these plugs, an inert agitating gas, nitrogen and/or argon are blown into the bath.


Operation

They are located in the floor of the furnace. Bath agitation homogenises both temperature and chemical composition.


Value proposition


Reduced hydrogen content in the bath.

Enhanced cleanliness of bath.

Increased melting capacity of furnace.

Minimum operating cost.

Cooling chambers


These are used for controlled or non-controlled cooling of previously treated parts. They are sometimes used as an active part of the treatment, and sometimes to shorten the cycle time.


Operation

Cooling chambers have a series of fans in their roof which blow air across the load, similarly to air in the heating furnace. Around the fan housing area are cold air intakes with adjustable flow rates, so a greater or lesser volume of cold air can be drawn in according to the cooling speed required.

These chambers can have a water-cooled cooling system, in which case they will be manufactured from stainless steel.

Value proposition


Coil treatment process time is shorter.

Quenching tanks


These perform cooling of parts to give them the desired metallurgical transformation.


Operation

These tanks can hold different fluids and are fitted with the appropriate control equipment. Quenching quality is measured by two thermography cameras located at the tank exit, which capture thermographic images of all parts as they exit the tank.

Value proposition


Rapid, homogenous quenching is achieved through use of jet and agitator systems.

Cutting saws


After heat treatment, aluminium billets are moved to the cutting saw where the ends are trimmed and, if required, they are cut to measure for subsequent feeding into the extrusion press.


Operation

Saws can be equipped with additional devices for extracting and compacting the shavings produced, and with auxiliary equipment for weighing, marking and strapping the billets.

Value proposition


Precision cutting.

Optimised production time.

Casting machines


We have developed a wide range of vertical casting machines for both billets and sheets.
The casting machine comprises a rack for dies, a moving tray and a platform driven by a self-guiding cylinder, which bears the weight of the platform itself and the ingots being die cast.

Value proposition


Virtually maintenance-free.

Smooth movement of platform.

Vibration-free.

No surface marks on billets or sheets.

Aluminium scrap loading machines


At GHI, we have developed different types of loading machine adapted for aluminium melting and holding furnaces. They have been designed specifically for this application so that furnaces can be loaded quickly and efficiently and protected from impact or inappropriate manoeuvres. Energy losses and non-productive idle time in furnaces are also minimised.

Operation

The machines are mounted on a trolley which moves them along the length of the furnace door(s) being served. The pan containing the load is fitted with a guiding system and mechanism for inserting the load. A third mechanism takes care of pushing the load from the pan to inside the furnace. The movement of both mechanisms is synchronised so that the pan withdraws at the same time as the pusher moves forwards, and in this way the load is deposited on the furnace hearth in the same arrangement as it was loaded into the pan.

The pan is open at the front, which enables the scrap load to be positioned easily. Once the load is ready, the manoeuvre for unloading it into the furnace is coordinated with furnace door opening, and therefore the entire operation is performed quickly and efficiently.


Value proposition


Fully automated operation.

Prevents damage to furnaces, and use of equipment not specifically for the purpose.

Optimal furnace use and energy consumption through preventing downtime.

Reduced staffing costs.
