hot top aluminum slab casting equipment
Product Description

Aluminum Slab Casting Machine (hot top)

Casting process: adopt the casting process of the top dense row in the same level, the use of a different mold to produce aluminum rods of different diameter sizes. Different crystallizers will produce different specifications diameter of aluminum slab.

Ingredients ---forklift loading (or use the automatic feedstock feeding machine) ---start melting furnace regenerative combustion system ---aluminium ingot and foundry return melting ---before loading batch played the slag, slag-off---aluminum billet and foundry return all melting---artificial mixing (electromagnetic stirring) and slag-off ---preliminary analysis---melt composition adjustment---add silicon and magnesium, etc ---check analysis---- melt composition adjustment ---refining slag-off (aluminium hot dross recycling machine)----metamorphic processing----degassing (online degassing device)) ---standing discharge points discharge through the degassing unit, filter box and flute into casting machine (control process temperature and melt quality enter the process ----aluminum billet casting or aluminum slab casting----aluminum billet homogenizing---aluminuium billet sawing, aluminum slab sawing--- packing----finished product of aluminum billet or aluminum slab stock.

The main feature of aluminum Slab casting machine

1. Casting type: round billet, square billet and hollow billet

2. Casting quantity of billet: 1~20 pieces

3. Casting slab size: 80mm~800mm

4 Crystallizer type: water curtain type, hole type.

5. Aluminum slab casting machine:  steel wire type or hydraulic type 

6. Aluminum slab casting table (mould),  hot top type, air slip type, oil mould type.
7. Aluminum slab casting machine can be equipped with automatic casting system, Casting LED Display for incrasing the production efficiency.

8. The feature of aluminum slab casting table:

The steel structure of casting table welded by A3 superior carbon steel, cooling water tank adopts round shape pressure boosting structure, the cover plate of water tank can be disassembly,the screw hole is equipment with the sleeve, can be convenience to replace the inner or outer screw (if the installed screw hole of billet mold disassembly too much times, it may damage the screw hole, so this design, only need to replace the screw sleeve, simple operation and easy to maintain quickly, it can extent the working life of equipment and reduce the operator labor). The thickness of main plate of water tank is 25mm, the thickness of protecting refractory plate and pressing plat is over 6mm steel plate. The thickness of cover plate of water tank is 12mm, round pipeline of cooling water adopts 120* 80 rectangle galvanization square tube, inner of water tank is zinc spraying treatment to avoid rusting. The joint which connect water tank, crystallizer, tilting arm has been machined to ensure top and bottom tolerance within ±0.2mm.

The feature of  new design of aluminum slab casting mold with fiter net

The slab mold can use copper material, so no need to use graphate ring and more durable.

1) Manual type of casting control operation: Manual operation: during casting process, water flow range will be operated by the worker to adjust the flow valve to the right position, casting speed will be controlled by the potentiometer on the operation table.
2)  Automatic type casting operation: download all of technical program through the tough screen, start on the preparation button on the operation table, the equipment system will check every valve position status. After the system is ready, when the aluminum liquid flow into the casting table and reach the casting requirement, start up the button of “start on”, PLC will monitor and regular the whole system according to setting data at the beginning. The flow data measured from the flow meter will switch the current signal to PLC, then PLC will output the signal after calculate the sent flow data and casting speed to pass to flow regulating valve, the valve will adjust the flow range, meanwhile, PLC will output the signal of casting speed regulation to convertor to achieve the casting speed regulation. After the casting start up work finished, the system will cast in smooth speed according to technical program. During casting process, if the aluminum liquid temperature is too high, it will need to change the casting speed, the operator can correct the data on the tough screen. This system will adjust the casting speed and cooling water flow automatically, so it can make sure the billet casting quality. When the casting work is going to finish, the system will adjust the cooling water and casting speed according to the setting data automatically, so that the end of billet can be smooth. After the all casting process completed, the operator can press the button of casting table up, the casting table will lift up quickly and automatically.
3) Latest design of aluminum slab, the size of the mold can be adjustable. The following pictues is showed the mold.
